What a plumbing & heating RAMS has to cover
Plumbing and heating work sits in an awkward spot for paperwork: most jobs are small, fast and in occupied buildings, but they regularly involve gas, hot works, electricity and water — four hazard groups that reviewers take seriously. A plumbing RAMS that reads like a generic construction document gets sent back because it misses the things that make this trade different: the boiler is in someone's kitchen, the soldering happens next to a joist, and the gas connection is a separate legal competence altogether.

Start from the actual task — boiler swap, pipework first fix, bathroom strip-out, plant room maintenance — and let the hazards follow from it. A boiler replacement RAMS should cover gas isolation and tightness testing, electrical isolation of the boiler circuit (lock-off and prove dead), drain-down with hot-water burns in mind, manual handling of a 30–40 kg appliance, flue routing (often work at height), and the occupants. Pipework jobs shift the emphasis to hot works: naked-flame soldering near combustibles is the single most scrutinised line in a plumbing method statement.
Gas work: keep the legal line clear
If the job touches gas, your RAMS needs to say who is Gas Safe registered and where their work starts and ends. Gas Safe registration is a statutory competence under the Gas Safety (Installation and Use) Regulations 1998 — it is not something a RAMS can substitute for, and reviewers know it. The clean pattern is one line in the scope ("gas work is carried out by a Gas Safe registered engineer — registration number X") plus gas-specific controls: isolation at the emergency control valve, tightness testing before and after, and the National Gas Emergency number in the emergency arrangements.

The same logic applies to unvented hot water (G3 competence) and electrical connections (Part P / a qualified electrician for notifiable work). Name the competence, name the person, and keep the boundary explicit. PCs reject documents that imply one operative is doing everything.
Occupied properties change the risk profile
Most plumbing work happens around occupants — householders, tenants, staff in commercial buildings. That changes three things in your RAMS. First, isolation: water, gas and heating outages need agreeing with the occupier, especially where someone vulnerable or medical equipment relies on supply. Second, segregation: the work area needs keeping clear of children and pets, with floors protected and tools not left unattended. Third, fire: hot works in a lived-in building need a fire extinguisher at the work position and a genuine check of the area once the torch goes cold — most solder-related fires are found after the plumber leaves.

Spell out the handover too: occupant briefed on the new system, certification left behind (Building Regulations notification, gas safety paperwork), and the work area reinstated. Reviewers read the last step of a method statement to see whether you actually finish jobs cleanly.
Plumbing & Heating RAMS FAQs
Do I need a RAMS for a simple boiler swap?
If a principal contractor, landlord, letting agent or commercial client asks for one — yes, and increasingly they do. Even unasked, a one-day boiler swap touches gas, electricity, hot works and manual handling, so a short site-specific RAMS is cheap insurance and quick to produce with the builder.
Does my RAMS cover the gas work legally?
No. Gas work is only lawful when done by a Gas Safe registered engineer — that's a statutory competence under the Gas Safety (Installation and Use) Regulations 1998. The RAMS documents how the wider job is managed; it should name the registered engineer and keep the boundary clear.
What certificates do PCs expect to see referenced?
Gas Safe registration for gas, G3 for unvented cylinders, Part P arrangements for notifiable electrical work, and trade competence (e.g. NVQ/time served) plus CSCS where the site requires it. Reference them in the competence section — don't attach everything unless asked.
Do I need a hot work permit for soldering in a house?
On domestic jobs you usually control it yourself: clear combustibles, extinguisher within reach, check the area afterwards. On commercial sites or under a principal contractor, expect a formal hot work permit — say in the RAMS that you'll work to it.
How do I make a plumbing RAMS site-specific quickly?
Use the report builder: pick Boiler installation, answer the job questions (gas? hot works? occupied? pre-2000?) and fill in the site details. The document updates as you answer and the PDF is free during early access.
