UK construction site-access products include biometric turnstiles from MSite, biometric attendance from CausewayOne Attendance, software sign-in and workforce platforms (Chime, SiteConnect, HammerTech), and Site Control. SiteConnect lists RAMS, CPP, COSHH, inductions and attendance on its UK platform pages. Site Control combines UK CDM generation, RFIs and contractor-company isolation with per-site pricing and unlimited workers.
Construction site-access products differ across physical access, attendance and compliance. Compare the perimeter controls, payroll workflows, document types and site records required.
Figures and features are taken from public vendor pricing and product pages first fetched on 2026-06-06. CausewayOne Attendance was rechecked 2026-10-05; Chime's facial-recognition and QR sign-in facts were rechecked 2026-07-28, and SiteConnect's Asset Management evidence was refreshed 2026-08-29. Quote-only vendors are flagged where no public price exists.

Quote-only, plus hardware capex per site (turnstile/biometric reader install).
No public price is listed for CausewayOne Attendance; contact Causeway for a quote.
Quote-only flat subscription scaled by annual construction volume and active job sites; no per-user fee, unlimited users, subcontractors free, implementation and support bundled.
UK: £625–£1,625 per quarter for 1–69 Managed Workers; 70+ is POA. 12-month minimum; unlimited subcontractor companies and their teams are included.
Team size
Per active site with unlimited workers (~75+ typical), multiple contractor companies and assigned-site Site Supervisor logins inherited from Business
Best for growing subcontractor firms with payrolled and CIS workforces, from roughly 20 operatives upward
Large enterprise workforces — hundreds to thousands of operatives across multiple secured sites.
Mid-size to large contractors and labour-heavy operations with payroll accuracy as the primary driver.
Enterprise GC safety, operations and EHS teams managing many concurrent projects and large subcontractor pools.
1–69 Managed Workers on published UK bands; 70+ is price-on-application. Direct employees, labour-only workers and some sole traders count; external subcontractor companies and their teams are included without separate licences.
Best for
Principal contractors and builders running live sites with subcontractors who need UK CDM documents generated plus on-site contractor access, attendance, RFIs and audit-ready evidence in one per-site tool.
Subcontractors and labour-heavy trades digitising timesheets, CIS payroll and field workforce management across multiple sites
Tier-1 and large main contractors securing high-value, high-throughput sites that need physical perimeter access control with biometric verification.
Construction contractors who want to eliminate time theft and buddy-punching with biometric attendance feeding accurate build-up-to-gross payroll.
Mid-to-large general contractors running multiple job sites who want one mature EHS and site-operations platform with optional turnstiles and equipment management.
UK construction teams seeking a workforce-priced H&S platform with RAMS, CPP, COSHH, inductions, attendance and subcontractor access.
Not ideal for
No biometric turnstiles or physical access control, so it cannot secure a Tier-1 perimeter the way hardware-led platforms like MSite can.
Distributes RAMS rather than generating them — no built-in UK RAMS/CPP/COSHH document creation, so the compliance pack still has to be authored elsewhere.
Hardware-led: turnstile and reader installations can involve per-site capex and groundworks; compare those requirements for a small or short-duration job.
No public entry price is listed; buyers need a quote for their chosen device and site setup.
Runs US-style JHAs, Safety Plans and SDS and does not generate UK RAMS, CPP or COSHH documents, so UK CDM packs still need a separate tool.
The UK platform lists RAMS, CPP and COSHH; no RFI or document-review acknowledgement workflow was listed on the reviewed pricing page.
RAMS / CPP / COSHH generation
Generates UK RAMS, CPP, COSHH and method statements from the project brief.
Chime distributes RAMS, toolbox talks and digital documents to individuals, groups, sites or trades, but does not generate the UK RAMS/CPP/COSHH documents themselves — you upload your own.
RAMS module lets contractors UPLOAD and managers approve/sign-off RAMS digitally; it stores and distributes documents rather than generating UK CDM RAMS/CPP/COSHH content.
Stores and distributes H&S documents and tracks induction completion, but does not generate UK RAMS/CPP/COSHH method statements. Site Control generates the full CDM pack.
Stores and distributes safety documents and runs US-style JHAs, Safety Plans and SDS; it does not generate UK RAMS, CPP or COSHH documents.
UK product and pricing pages list RAMS, CPP and COSHH in the complete platform; no AI generation claim is made here.

Permits to work
Document distribution and digital forms/checklists can cover permit-style sign-offs, but there is no dedicated named permit-to-work workflow advertised.
Briefings, RAMS sign-off and access gating cover much permit-style control; no dedicated permit-to-work issuance module is publicly documented.
No dedicated permit-to-work workflow surfaced on the product pages; focus is attendance, payroll and inductions rather than permit issue/approval.
Dedicated Permits module within the Coordinate workflow; permit depth is a recognised HammerTech strength.
UK construction pages list digital permit forms; reviewed pages do not establish the full issue, approval and close-out workflow.
Site inductions
Digital induction blocks check-in until acknowledged - readable in 9 worker languages.
Digital site inductions are a core feature, delivered in-app alongside RAMS and toolbox talks.
Online inductions software with forms, videos, questionnaires and 30+ language auto-translation; access is gated via biometric verification before entry.
Ensures workers complete safety training and site inductions before site access — induction gating is explicitly advertised.
Orientations and worker onboarding module gates worker readiness before site access.
UK education page says contractors cannot sign in until their digital induction is complete.
Multilingual inductions (9 languages)
Workers read and acknowledge key H&S details in 9 languages at the entrance QR; the language used is recorded in the audit trail and translations are site-team reviewable.
—
—
—
—
—
RAMS sign-off (per worker)
Per-worker RAMS acknowledgement can block check-in until the current version is signed. Optional 4-digit PINs add evidence to shared-link document sign-off without changing attendance.

Worker cert tracking
CSCS upload, internal review and expiry notifications.
Skills and certifications (including CSCS-type competencies) are tracked per worker as part of workforce/subcontractor management.
Competency and credential management is part of the workforce suite; credentials are checked against the worker before access is granted.
Tracks training and qualifications/competency records as part of the digital worker ID; supports verified audit trails.
Worker info, qualifications and orientation tracking with expiry handling as part of subcontractor management.
Contractor management and registers cover compliance documents; compare the listed competency and certificate-expiry alerts with the site's CSCS tracking requirements.
Right to work
Records Home Office share-code checks with outcome, expiry and an evidence file (manual verification, not a live API).
Right-to-work verification is included in onboarding/subcontractor management.
Identity checks and pre-registration support right-to-work/identity verification at enrolment, strengthened by biometric identity confirmation at the gate.
Tracks Right-to-Work records as part of a compliance audit trail.
Captures worker credentials and onboarding data; UK right-to-work share-code verification is not a documented native feature.
No formal UK right-to-work ID or share-code verification surfaced; focus is H&S compliance, not immigration checks.
Contractor self-onboarding
Contractor self-join via the entrance QR with CSCS upload and approval.
Strong subcontractor onboarding and management is core, though it is framed as employer-driven onboarding rather than a worker self-enrolment QR flow.
Pre-registration software lets subcontractors and workers self pre-enrol and complete induction before their start date.
Worker enrolment is supported via the mobile app and biometric capture, but onboarding is generally enrolment-led rather than contractor-company self pre-enrolment.
Subcontractor management lets sub firms self-complete onboarding; subcontractor access is free.
Contractors connect free without a licence fee and self-manage their company profile and compliance via contractor management.
QR / mobile sign-in
Permanent entrance QR for guest sign-in/out and contractor self-join.
Chime advertises mobile app sign-in via QR code, GPS or PIN with optional selfie/photo; its product features also list QR Sign In and multiple QR codes across areas.
Primary model is biometric turnstiles plus Workforce/Supervisor apps; sign-in is hardware-led rather than a no-hardware QR entrance.
Primary check-in is biometric readers plus a GPS mobile app for remote workers; not positioned as a no-hardware QR sign-in like Site Control's entrance QR.
IronGate access supports QR codes and pin codes alongside facial recognition; mobile app handles field sign-in.
Public QR code sign-in lets visitors check in without downloading the app.
GPS clock-in
GPS-verified clock-in is a headline feature — location captured at sign-in/out to confirm who is on site in real time.
Workforce App now advertises clock-in/out via Face Mini facial recognition or location check-in; public copy doesn't prove geofenced auto clock-in, so treated as partial.
GPS mobile app supports virtual geofences for site attendance before physical boundaries are defined.
Attendance is captured via turnstiles and app; geofenced GPS clock-in is not a documented core feature.
Geofencing sets virtual boundaries around sites and auto signs users in/out on entry, exit or dwell.
Biometric access
Advertises secure facial-recognition/selfie sign-in in its app — operatives take a selfie at sign-in/out alongside GPS/time evidence. App-based, not fixed biometric turnstile hardware.
Core strength — MSite Face facial recognition confirms the worker's identity before access.
Core differentiator: fingerprint and facial-recognition devices verify identity to the minute and eliminate buddy-punching. Site Control has no biometric.
IronGate partner turnstiles provide facial-recognition biometric access.
No fingerprint or facial-recognition access; sign-in is geofence, QR or kiosk based.
Physical access control
No turnstiles or gates — Chime markets itself as hardware-free, using the mobile app for access and attendance.
Full/half-height turnstiles, Pod units, cabins and gates provide a physical secured perimeter — the flagship capability.
Biometric readers/tablets gate logging at site points; can integrate with hardware, but it is not primarily a turnstile/gate access-control platform.
IronGate facial-recognition turnstiles and gates engineered for harsh construction conditions.
Software-based sign-in only; no turnstiles or gate hardware integration documented.
Site attendance
Check-in/out, history and a live people-on-site view.
Time & attendance is foundational; digital timesheets are auto-created at sign-in/out with real-time hours.
Time and attendance with timesheets and labour-hour management captured at biometric turnstiles.
Captures hours worked to the minute via biometrics with automated overtime — the product's central T&A capability.
Site Access plus IronGate sync labour hours and attendance in real time.
Attendance is one of the four core pillars, recording site visitors and sign-in/out times.
CIS payroll
Hours flow straight to payroll with CIS calculated automatically — a clear differentiator versus Site Control.
Labour-hour/timesheet data supports CIS/IR35 workflows via integrations; not positioned as an in-product timesheet-to-pay engine.
Builds up to gross pay with automated overtime; the current Attendance page does not confirm CIS deductions or returns.
Captures labour hours but no documented UK CIS timesheet-to-pay payroll module.
No CIS timesheet-to-pay or payroll export surfaced; attendance data is for H&S not pay.
Live people-on-site
Triggered evacuation + muster roll-call: snapshot who is on site, mark each person safe, export a roll-call PDF.
Real-time field management shows who is on site at any moment via GPS-verified clock-ins.
Real-time on-site monitoring and attendance from turnstile entry/exit supports muster and roll-call.
Real-time monitoring across multiple locations shows who is on site; supports labour tracking and audit trails.
Turnstile and access data give real-time who-is-onsite visibility for muster and evacuation.
Real-time attendance records who is on site, supporting evacuation and muster needs.
Multi-company isolation
Each contractor company sees only its own workforce — test-verified.
Built to manage in-house teams and subcontractors together from a contractor's account; no advertised test-verified per-contractor-company data isolation portal.
Enterprise workforce management with subcontractor onboarding implies role/company scoping; per-contractor data isolation is not a publicly verified, test-backed claim.
Built for contractors managing their own and subcontractor labour, but multi-contractor-company data isolation is not advertised or test-verified as it is in Site Control.
Built around GC-managed projects with free subcontractor access; per-company data isolation is implied by role model but not publicly test-verified.
Contractor management connects multiple companies and includes their teams; confirm with the vendor which records each contractor company can access.
RFIs
Create, attach, comment, answer and close.
No request-for-information workflow advertised; Chime focuses on workforce, timesheets and H&S documents rather than project Q&A.
No request-for-information (RFI) workflow is part of the access-control/workforce platform.
No request-for-information workflow; Donseed is an attendance/payroll/compliance tool, not a site-coordination platform. RFIs are unique to Site Control here.
Focused on EHS and site operations; no request-for-information workflow documented on the platform pages.
No request-for-information workflow; the platform centres on H&S compliance, not project coordination.
Document-review evidence
Version-specific read/acknowledge audit chain.
Documents are distributed and acknowledged in-app, but there is no advertised version-specific read/acknowledge audit chain like Site Control's.
RAMS digital briefings record sign-off, and inductions capture acknowledgement, providing a read/acknowledge audit trail.
Records induction and training completion with audit trails, but not version-specific document-review acknowledgement chains like Site Control.
Bulletins and safety meetings capture acknowledgements; a version-specific document-review audit chain is not explicitly documented.
Toolbox talks capture digital signatures and attendance; a version-specific read/acknowledge audit chain for documents is not clearly evidenced.
Handover sign-off
Per-plot, per-trade hand-over sign-off is captured in person on one phone; a certified PDF is emailed to the developer and contractor, with a per-plot progress board.
Toolbox talks
Toolbox talks are distributed and acknowledged in-app alongside RAMS.
Briefings module broadcasts safety briefings/toolbox talks with verified sign-off via the worker apps and gate.
Health & safety and training tracking is supported; broadcast-and-acknowledge toolbox talks are not specifically advertised as a discrete feature.
Safety Meetings and Bulletins modules cover broadcast toolbox talks and acknowledgement.
Toolbox talks support scheduling, attendance tracking and digital signatures for daily briefings.
Site inspections
Inspections and checklists are part of the platform, with photo and location capture.
Broader Infobric/QHSE tooling covers inspections; not a core advertised feature of the MSite access-control module itself.
No dedicated site-inspection workflow surfaced; the product centres on attendance, payroll and worker compliance records.
Mature Inspections module within the Report workflow; inspections maturity is a HammerTech strength.
Pre-start checklists and customisable mobile forms cover daily site safety inspections (PPE, barriers, signage).
Incident log
Digital forms/checklists and reporting can capture incidents, but a dedicated incident log is not separately named in public materials.
Fatigue management and QHSE tooling touch on incident/safety reporting; a dedicated incident log is not prominently documented in the access-control module.
Includes H&S training and attendance audit trails, but a structured incident log is not advertised as an Attendance feature.
Incidents and Injuries module for reporting, tracking and investigation.
Incident and injury management lets teams report and investigate incidents with custom workflows.
Plant / asset management
Business and Site Control include spreadsheet import, project assignments, configured evidence, inspections, defects, quarantine, exports and Audit Pack history.
Asset tracking is an advertised module; Site Control covers register records, evidence and project assignments but not GPS or payroll automation.
No plant or asset management capability is documented in the workforce/access-control suite.
No plant/asset register; Causeway offers separate products for plant, but Donseed itself is workforce-focused.
Equipment Compliance module covers plant and equipment registers, operator checks, servicing alerts and pre-start inspections.
SiteConnect Asset Management covers plant, equipment, vehicles and tools: register, inspection/maintenance reminders, QR labels, linked hazards/incidents/tasks, bulk import and CSV/XLSX/PDF export.
Workforce scheduling
Real-time field/workforce management is central, though public materials emphasise time capture and management rather than dispatch/rostering.
Labour requisitioning helps plan labour needs, but full dispatch/rostering scheduling is not a headline feature.
Provides labour tracking; full dispatch or rostering is not advertised as an Attendance feature. Site Control has no scheduling either.
Logistics schedules site deliveries, crane lifts and work zones; no workforce shift or dispatch roster is advertised.
No dispatch or rostering/scheduling capability documented; focus is compliance not workforce planning.
Multi-site dashboard & exports
Attendance CSV, monthly H&S CSV/PDF and project audit-log exports.
Centralised multi-site view with real-time management reporting and PDF/share/save exports.
Multi-site dashboards and reporting consolidate attendance, labour hours and compliance across a contractor's project portfolio.
Real-time monitoring across multiple locations with project insights for commercial, operations and H&S, plus payroll/timesheet reporting.
Reporting and Insights real-time analytics dashboard spans multiple job sites with exportable data.
Compliance dashboard with real-time analytics and PDF export supports audits across sites.
Mobile app
No native app required; workers scan the entrance QR and use the browser on their own phone.
Native iOS and Android app (Chime Construction Software) for clock-in, documents and checklists.
Workforce App and Supervisor App provide mobile access for workers and site supervisors.
Native mobile app (iOS/Android) with GPS clock-in for remote workers, alongside fixed biometric readers/tablets on site.
Native iOS and Android apps linked from the platform pages for field use.
Native mobile app on iOS and Android gives workers access to materials from their phone.
Offline mode
Field app captures data on site; an explicit offline mode is not confirmed in public materials.
Turnstile hardware operates locally at the gate, but documented offline behaviour for the apps is not publicly specified.
The mobile app supports online and offline modes for use when signal coverage is limited.
Mobile app is used in the field; offline capability is plausible but not explicitly documented on public pages.
Mobile-first field use is emphasised but offline capture behaviour is not clearly documented.

Full breakdown per product
Strengths, weaknesses, fit, and the sources every claim came from.
From £675/site per month plus £5,000 one-off setup; volume tiers as sites scale
Best for
Principal contractors and builders running live sites with subcontractors who need UK CDM documents generated plus on-site contractor access, attendance, RFIs and audit-ready evidence in one per-site tool.
Team size
Per active site with unlimited workers (~75+ typical), multiple contractor companies and assigned-site Site Supervisor logins inherited from Business
Sweet spot
A principal contractor running one or more active sites who must generate the CDM pack, control who is inducted and on site, run RFIs, and produce audit-ready attendance and H&S exports without hardware.
Strengths
Generates UK RAMS, CPP, COSHH and method statements, and captures worker sign-off on site.
Per-site pricing with unlimited workers (~75+) and test-verified multi-contractor-company data isolation, instead of per-seat or per-turnstile economics.
No hardware: a permanent entrance QR plus browser sign-in on the worker's phone means a new site needs no turnstile capex or install.
Combines RFIs, document-review evidence, CSCS and induction gating, attendance and audit-grade exports in one tool — plus SSO (Okta / Microsoft Entra), a scoped REST API and signed webhooks for enterprise IT.
Plot-by-plot hand-over sign-off: capture every trade signed off on every plot in person, with a certified PDF and a live progress board.
The Audit Pack can include per-worker RAMS sign-off (with check-in blocked until the current method statement is signed), right-to-work evidence with expiry, and a triggered evacuation roll-call PDF.
Weaknesses
No biometric turnstiles or physical access control, so it cannot secure a Tier-1 perimeter the way hardware-led platforms like MSite can.
No CIS payroll or GPS-geofenced clock-in, so payroll-accuracy-led buyers may prefer Chime or Donseed.
No plant or workforce scheduling, dispatch or telematics — the Plant register is evidence-led rather than a fleet operations suite.
Site Control is a newer plan, introduced in 2026, for principal contractors managing site access and compliance workflows.

Growth plan has a published annual price calculator that varies by operative count; check the live calculator for a current total. Higher tiers require a quote
Best for
Subcontractors and labour-heavy trades digitising timesheets, CIS payroll and field workforce management across multiple sites
Team size
Best for growing subcontractor firms with payrolled and CIS workforces, from roughly 20 operatives upward
Sweet spot
A subcontractor running mobile crews who wants GPS-verified clock-in flowing straight into CIS payroll, with RAMS distribution and asset tracking bundled in
Strengths
GPS-verified clock-in feeding digital timesheets straight into CIS payroll with calculations automated — a genuinely strong field-to-pay pipeline Site Control does not attempt.
The vendor describes a hardware-free deployment that avoids hardware procurement for mobile crews.
Broad workforce-management footprint: T&A, onboarding, skills, right-to-work, asset tracking and inspections in one subcontractor-focused platform.
Real-time multi-site reporting with native iOS/Android apps, well suited to labour-heavy subcontractors managing operatives across many jobs.
Weaknesses
Distributes RAMS rather than generating them — no built-in UK RAMS/CPP/COSHH document creation, so the compliance pack still has to be authored elsewhere.
No request-for-information (RFI) workflow or version-specific document-review audit chain, so project Q&A and acknowledgement evidence live outside the tool.
Growth pricing varies by operative count in Chime's public calculator, making it a substantial commitment for a sole trader or small crew; higher tiers require a sales quote.
Built around a contractor managing its own workforce, not multi-contractor-company data isolation for a principal contractor running a shared site.
Quote-only, plus hardware capex per site (turnstile/biometric reader install).
Best for
Tier-1 and large main contractors securing high-value, high-throughput sites that need physical perimeter access control with biometric verification.
Team size
Large enterprise workforces — hundreds to thousands of operatives across multiple secured sites.
Sweet spot
Major projects where a biometric turnstile perimeter, fatigue management and labour-hour reporting justify hardware capex and a quote-based rollout.
Strengths
MSite Face facial-recognition readers, turnstiles, Pods and gates provide biometric identity checks and physical site-entry controls.
End-to-end Tier-1 workforce platform — pre-registration, induction, access, T&A, briefings, RAMS approval and labour reporting in one enterprise suite.
Facial-recognition checks are used alongside worker credential verification at the gate.
Multi-site dashboards and labour-hour reporting suit large main contractors managing big subcontractor populations across many sites.
Weaknesses
Hardware-led: turnstile and reader installations can involve per-site capex and groundworks; compare those requirements for a small or short-duration job.
Pricing is quote-only, with no public price; buyers need to request a quote to compare costs.
RAMS module approves and distributes uploaded documents rather than generating UK CDM RAMS/CPP/COSHH content for you.
No request-for-information (RFI) workflow, and offline/data-isolation specifics are not publicly verifiable.
Quote-only flat subscription scaled by annual construction volume and active job sites; no per-user fee, unlimited users, subcontractors free, implementation and support bundled.
Best for
Mid-to-large general contractors running multiple job sites who want one mature EHS and site-operations platform with optional turnstiles and equipment management.
Team size
Enterprise GC safety, operations and EHS teams managing many concurrent projects and large subcontractor pools.
Sweet spot
Multi-site GCs in the US/AU/UK that prioritise breadth of safety modules, permit depth and access-control hardware over UK-CDM document generation or a self-serve per-site product.
Strengths
Most feature-complete rival in this comparison set: deep permits, mature inspections, incidents and equipment/plant management in one platform.
Optional IronGate facial-recognition turnstiles and gates provide physical access control through installed hardware.
No per-user fee with unlimited users and free subcontractor access, plus implementation, training and support bundled into the subscription.
Long track record across the US, Australia and UK with mid-to-large general contractors and enterprise EHS teams.
Weaknesses
Runs US-style JHAs, Safety Plans and SDS and does not generate UK RAMS, CPP or COSHH documents, so UK CDM packs still need a separate tool.
Pricing is quote-only, with the annual fee based on construction volume and active job sites; buyers need a sales quote to compare their costs.
No request-for-information (RFI) workflow, which collaboration-heavy site teams may expect.
Breadth and enterprise onboarding are aimed at larger contractors. A buyer considering one UK site can compare its required workflows with the platform's modules and quoted scope.
UK: £625–£1,625 per quarter for 1–69 Managed Workers; 70+ is POA. 12-month minimum; unlimited subcontractor companies and their teams are included.
Best for
UK construction teams seeking a workforce-priced H&S platform with RAMS, CPP, COSHH, inductions, attendance and subcontractor access.
Team size
1–69 Managed Workers on published UK bands; 70+ is price-on-application. Direct employees, labour-only workers and some sole traders count; external subcontractor companies and their teams are included without separate licences.
Sweet spot
UK construction teams that want a complete H&S platform priced by Managed Worker count, with unlimited sites and subcontractor companies.
Strengths
UK pricing is published by Managed Worker band, with quarterly billing on a 12-month agreement and an onboarding fee quoted for each implementation.

Short, straight answers - the same questions real builders ask.
What is the best construction site access software in the UK?
It depends on what you need. For securing a Tier-1 perimeter, MSite's biometric turnstiles lead. For biometric time and attendance feeding build-up-to-gross payroll preparation, Causeway Donseed is strong. For a principal contractor who must generate UK CDM documents such as RAMS, CPP and COSHH and run per-site contractor access, attendance and RFIs in one tool, Site Control combines document generation with on-site access and RFIs; SiteConnect lists UK CDM documents and a complete H&S platform priced by Managed Workers.
Does site access software handle RAMS and CDM paperwork?
SiteConnect lists RAMS, CPP and COSHH on its UK platform pages; its public material also describes building structured, site-specific RAMS and CPPs. Site Control documents those CDM workflows alongside site access and worker sign-off. Other products in this roundup focus on different access or safety workflows; compare current feature details.
Is per-site or per-user pricing better for site access software?
Which pricing model is better depends on the site. SiteConnect UK prices by Managed Worker band: £625–£1,625 per quarter for 1–69, with 70+ on application. External subcontractor companies and their teams are included; a 12-month minimum and quoted onboarding fee apply. Site Control charges a per-site fee, from £675 per site per month plus setup, with unlimited workers, which stays predictable when dozens of operatives and subcontractors come and go from one project over its life.
Do you need hardware for construction site access control?
Not always. MSite's turnstiles physically secure a perimeter. CausewayOne Attendance supports biometric devices, compatible tablets and smartphones, so equipment needs depend on the chosen setup. Software sign-in options, including Chime, SiteConnect and The Site Book's Site Control, do not require a turnstile installation. Choose based on whether the site requires a physically controlled perimeter.
Which site access tool is best for small UK builders?
SiteConnect publishes UK pricing by Managed Worker band and includes unlimited subcontractor companies and their teams. Compare the band definitions, onboarding quote and workflows against your site requirements. Site Control combines RAMS, CPP, COSHH, attendance, RFIs and audit exports per site. SiteConnect lists UK CDM documents and site workflows on a Managed Worker pricing model; compare the project records and access controls required. Heavy biometric or payroll platforms are usually overkill for a small builder.
