RAMS & CPP for Bathroom Renovations
What compliance documents you need for bathroom refits, wet rooms, and plumbing work — and how The Site Book handles it for you.
What compliance do you need?
Bathroom renovations involve a unique mix of trades — plumbing, electrical, tiling, and often structural work. Because you're combining water, electricity, and confined spaces, the risk profile is higher than many people expect. CDM 2015 applies to all construction work, including domestic bathroom refits.
Do you need a CPP?
Yes. Every construction project needs a Construction Phase Plan under CDM 2015. For a bathroom renovation, your CPP should cover how you'll manage the electrical work safely, how you'll deal with any asbestos, and how multiple trades will be coordinated in a small space.
Do you need RAMS?
RAMS are strongly recommended for bathroom work. Electrical installations in wet zones, working with hot water systems, and potential asbestos in older properties all carry significant risks. If you're working for a main contractor or housing association, RAMS will almost certainly be required.
Common hazards
- Electrical work in wet environments (zones 0, 1, and 2)
- Asbestos in older properties (floor tiles, pipe lagging, artex ceilings)
- Slips and trips on wet surfaces
- Manual handling of heavy items (baths, shower trays, tiles)
- Hot works when soldering pipework
- Dust from cutting tiles and removing old plaster
- Working with silicone sealants and adhesives (COSHH)

Frequently asked questions
- Do I need RAMS for a bathroom renovation?
- RAMS are strongly recommended for bathroom renovations, especially where there is electrical work in a wet environment, asbestos removal in older properties, or work involving hot water systems. Many clients and main contractors will expect RAMS before you start work on site.
- What regulations apply to electrical work in bathrooms?
- Electrical work in bathrooms must comply with BS 7671 (IET Wiring Regulations), particularly the requirements for special locations. Work must be carried out by a competent person and notified to Building Control under Part P of the Building Regulations. Zones 0, 1, and 2 have specific requirements for IP ratings and RCD protection.
- Do I need a CPP for a domestic bathroom refit?
- Yes. Under CDM 2015, a Construction Phase Plan is required for all construction projects, including domestic bathroom renovations. On domestic projects with a single contractor, you take on all CDM duties and must plan and manage the work safely.
