Plumbing and heating RAMS sit at an unusual intersection: most of the work happens in occupied buildings, much of it involves hot works covered by insurer permits, and a significant share is in pre-2000 domestic property where the asbestos refurbishment-and-demolition (R&D) survey regime under CAR 2012 still applies. A strong plumbing RAMS treats hot works, asbestos and the occupier interface as first-class topics, not afterthoughts.
Most UK commercial insurers require a hot works permit for any soldering, brazing or grinding activity, and the standard permit (FPA HW01 or insurer-specific equivalents) imposes a 60-minute post-work fire watch. RAMS that name hot works but omit the fire watch are the single most common reason a plumbing RAMS gets sent back by a principal contractor or insurer's surveyor.
The permit also requires the area to be cleared of combustibles within 10 metres, a fire blanket or board to be placed behind the work, and a serviceable fire extinguisher (CO2 or dry powder) to be present and named in the RAMS by location and inspection date. The RAMS should describe how the contractor will close out the permit at end of day, including who carries out the fire watch and where they will be.
The majority of plumbing and heating callouts in the UK happen in someone else's home or workplace. The Management of Health and Safety at Work Regulations 1999 require employers to take account of risks to persons not in their employment — for plumbing that means the occupier, the occupier's family, and any visitors. A strong RAMS covers the occupier-interface explicitly: how the working area will be cordoned, what happens to the water supply during the work, what the operative will do if they find the property is occupied by a vulnerable person (very young children, elderly, mobility-impaired), and the protocol for unaccompanied access where the occupier has left a key.
For lone working in unoccupied properties — common for landlord-instructed maintenance — the RAMS should describe the lone-worker check-in protocol. A missed check-in is the most common trigger for a welfare emergency in this category of work.
The Control of Asbestos Regulations 2012 (CAR 2012, SI 2012/632) require anyone working on the fabric of a non-domestic building to have access to the dutyholder's asbestos register or to commission a refurbishment-and-demolition (R&D) survey before disturbing the fabric. For domestic property the survey duty falls on the contractor planning the work — there is no domestic dutyholder.
Plumbing work routinely disturbs the kinds of materials where asbestos is found in older buildings: pipe insulation, gasket material, toilet cisterns, AIB ceiling tiles in airing cupboards, textured coatings. The RAMS should set out the refusal protocol — what the operative does if they discover suspected ACMs once work has started — and the route to a licensed removal contractor where the material is licensed. Non-licensed work (NNLW) on small quantities of low-risk material is permitted under CAR 2012 reg 3(2), but only if the operative has been trained to the standard required by ACoP L143.
Any work on gas installations in the UK must be carried out by a Gas Safe registered engineer under the Gas Safety (Installation and Use) Regulations 1998 (GSIUR, SI 1998/2451). The RAMS should name the engineer's Gas Safe registration number, the categories they are competent to work in (CCN1, CENWAT, CKR1 etc.), and the isolation procedure for the meter and the appliance. For unvented hot water systems (G3) the engineer must also hold the corresponding G3 qualification.
A plumbing RAMS that covers wet plumbing only does not cover gas — the gas element needs its own RAMS or a clearly bounded section that addresses the Gas Safe rules specifically.

Plain-English guidance for plumbers and heating engineers on the asbestos materials they typically encounter.
On a commercial site or in any insured property with a hot works clause in the policy: yes. Most UK property insurance policies require a permit for any work involving naked flame or temperature above 100°C regardless of duration. On uninsured work in the operative's own workshop the permit is not legally required, but the underlying hazard is the same and the RAMS should still set out the controls.
Sometimes. The Control of Asbestos Regulations 2012 distinguish licensed work, notifiable non-licensed work (NNLW) and non-licensed work. Pipe lagging in good condition that is removed in one piece in small quantities (under 60 minutes of work over a 7-day period per worker) can fall into NNLW if the operative is trained to L143 standard. Anything friable, damaged or larger is licensed. If in doubt, stop and call a licensed contractor.
Name the system being worked on, state whether the alteration creates new dead legs or removes them, describe the flushing regime after re-commissioning, and reference HSG274 part 2. For a domestic boiler swap there is rarely a Legionella issue; for a commercial calorifier replacement or pipework alteration on a low-use building, it is material and should be addressed explicitly.
Both. The contractor signs as the duty holder for the document's accuracy. The principal contractor signs to accept it for use on their site under CDM 2015 reg 13(4). For domestic work outside CDM scope, only the contractor signs, but the customer / client should be informed of any controls that affect their access to the property.
Not if the work, materials and controls are the same. A single template RAMS with a property-specific addendum (address, building age, asbestos check result, occupier notes) is acceptable and is the standard model for landlord-instructed maintenance work. The addendum is what makes the document site-specific.
