Why Your RAMS Keep Getting Rejected (And How to Fix Them Before Work Starts)

Getting your RAMS rejected by a principal contractor is more than an inconvenience. It means your start date moves, your relationship with the main contractor takes a hit, and in some cases you lose the job entirely to someone who had their paperwork in order.

The frustrating part is that most rejections come down to the same handful of fixable mistakes. Not complex legal errors. Not missing qualifications. Just documents that read like they were written for a different site, a different job, or nobody in particular.

The five most common reasons RAMS get rejected in 2026, according to HSE Network: vague task descriptions, incorrect control hierarchy, missing risk rating methodology, generic template content, and no competent person sign-off.

This guide works through each one. Fix these, and your RAMS will pass first time.

Before you read on: RAMS approval sits with the principal contractor, not building control. Building control checks structural compliance and building regulations. The principal contractor checks your RAMS under their CDM 2015 duties. These are separate processes, and confusing them is itself a common source of delays.

Why principal contractors reject RAMS

Under CDM 2015, principal contractors are legally required to ensure every subcontractor on site has suitable and sufficient risk assessments in place before work begins. That means they cannot simply wave your document through. If it does not clearly demonstrate that you have identified the specific hazards on their site and put adequate controls in place, they have to send it back.

This is not bureaucracy for its own sake. HSE guidance is clear: principal contractors cannot discharge their legal health and safety responsibilities under CDM 2015 without credible, site-specific risk assessments.

The practical consequence for subcontractors is that your RAMS need to satisfy two audiences at once: the HSE standard (is this legally compliant?) and the principal contractor's approval process (does this tell me enough about how you will work safely on my site?).

Most rejections happen because documents pass the first test but fail the second.

The 48-hour rule

Submit your RAMS at least 48 hours before you are due on site. This is not always a hard legal requirement, but it is standard practice across most principal contractor approval workflows. Leaving it until the morning you are due to start means any rejection, however minor, will delay your start. Build the 48-hour buffer in as a default.

The five most common rejection reasons (and how to fix them)

1. Vague task descriptions

This is the single most common rejection reason. A task description like "installation of first fix pipework" tells a principal contractor almost nothing. Where on the site? What floor? What access is required? Are there other trades working nearby?

A principal contractor reviewing your RAMS needs to be able to picture your team doing the work in their specific building. If they cannot, they will send it back.

The fix: Describe the task as if you are explaining it to someone who has never seen the site. Include the location within the building, the sequence of work, the tools and equipment you will use, and how long each stage will take.

"First fix copper pipework installation on ground floor, kitchen and utility room, working from floor level using stepladders. Duration: 2 days. Other trades on site: electricians working in adjacent rooms."

That is the level of detail that passes.

2. Incorrect control hierarchy

The hierarchy of controls requires you to address hazards in a specific order: eliminate the risk first, then substitute, then engineering controls, then administrative controls, and PPE last. Many RAMS jump straight to PPE as the primary control, which signals to a principal contractor that the document was not properly thought through.

The fix: Work through the hierarchy genuinely for each hazard. For manual handling of heavy materials, the hierarchy might look like this:

• Eliminate: Can the task be redesigned to remove the lift entirely?
• Substitute: Can lighter materials or pre-cut sections be used?
• Engineering controls: Mechanical handling aids, trolleys, lifting equipment
• Administrative controls: Two-person lifts, rest breaks, trained operatives only
• PPE: Back support belt, safety footwear

PPE appears, but it is the last line of defence, not the only one.

3. Missing risk rating methodology

If your RAMS includes risk ratings (high, medium, low) but does not explain how you arrived at them, a principal contractor cannot verify the assessment is credible. A risk rated "low" with no scoring method behind it is meaningless.

The fix: Use a 5x5 risk matrix and show your working. Rate likelihood (1-5) and severity (1-5) before and after controls are applied. The free risk assessment template on The Site Book includes a pre-built 5x5 matrix with scoring guidance. Include the matrix in your document, or reference the methodology you used.

4. Generic template content

A principal contractor who reviews RAMS every week can spot a copied template in seconds. Phrases like "workers will take care when working at height" or "appropriate PPE will be worn at all times" appear in thousands of documents and say nothing specific about your job.

Generic content is the fastest route to rejection. It signals that the RAMS was not written for this project, which means the hazards specific to this project have not been considered.

The fix: Every section of your RAMS should reference the actual site. Use the address. Name the specific tasks. Reference the conditions you found on your site visit. If you are working near a party wall, say so. If access is through a narrow corridor with a low ceiling, say so. The more site-specific the document, the more credible it is.

For a deeper look at what good looks like, see the step-by-step RAMS writing guide on The Site Book.

5. No competent person sign-off

Your RAMS must be signed off by someone with the competence to assess the risks involved. That means the document needs to include the assessor's name, their role, their relevant qualifications or experience, and the date of assessment.

A RAMS with no sign-off, or one signed by an unnamed "site manager", will be returned.

The fix: Include a sign-off block on the document that captures:

• Full name of the assessor
• Job title and company
• Relevant qualifications (CSCS card level, SMSTS, SSSTS, trade-specific certifications)
• Date of assessment
• Review date, especially for longer projects

If you are a sole trader doing the assessment yourself, that is fine. Sign it yourself, include your qualifications, and date it.

Before you submit: a quick pre-approval checklist

Run through this before sending your RAMS to the principal contractor. It takes two minutes and will catch the most common rejection triggers.

If you are resubmitting after a rejection, read the feedback carefully. Principal contractors will usually tell you which section failed. Fix that section specifically, then re-read the whole document with fresh eyes before sending it back.

Common questions about RAMS rejection

Can a principal contractor reject my RAMS without telling me why?

Technically yes, but in practice most will indicate which section failed. If you receive a rejection with no feedback, ask directly. You are entitled to know what needs to change. A brief email asking "could you confirm which sections need amending?" is reasonable and professional.

Does my RAMS need to match the principal contractor's template?

No. You own your RAMS and are responsible for their content. A principal contractor may ask you to use their format or cover page, but they cannot require you to transfer ownership of the document. If they ask you to reformat, check that the substantive content remains yours and has not been altered.

What if my RAMS was accepted on a previous job and rejected on this one?

Different principal contractors have different approval standards. A document that passed on one site may not pass on another, particularly if the new site has different hazards, access conditions, or a more rigorous review process. Always tailor your RAMS to the specific job rather than reusing a previous version unchanged.

Do I need separate RAMS for each trade or task?

It depends on the scope of work. If you are doing multiple distinct tasks with different hazard profiles (for example, groundworks and then internal fit-out), separate RAMS for each activity is cleaner and easier for the principal contractor to review. If the tasks are closely related and share the same hazards and controls, a single document covering all of them is fine.

What does SSIP accreditation have to do with RAMS approval?

SSIP (Safety Schemes in Procurement) accreditation demonstrates that your company meets a baseline standard for health and safety management. Some principal contractors require SSIP accreditation before they will accept your RAMS at all. It does not replace RAMS, but it can smooth the approval process and reduce the scrutiny your documents receive.

Get your RAMS right first time

Most RAMS rejections are preventable. The five issues covered in this guide (vague descriptions, wrong control hierarchy, missing risk ratings, generic content, and no competent sign-off) account for the vast majority of documents that get sent back.

The underlying problem with all of them is the same: the document was not written for this site, this job, and this principal contractor. Fix that, and the approval process becomes straightforward.

If you want to produce site-specific, CDM-compliant RAMS without spending hours on paperwork, The Site Book generates RAMS from a plain-English job description.

Describe what you are doing, where, and with what, and it produces a document built around your specific project, not a generic template. You can also check the builders' RAMS and CDM compliance page to see what documents are typically required for your type of work.
