Plumbers and heating engineers work in other people’s homes and workplaces, in lofts, under floors and in cupboards, with blowtorches, pressurised systems and hot water. Clients, housing associations and principal contractors usually want to see a RAMS that shows you have thought about hot works, water temperatures, access and the people living or working around you.

Gas work adds its own requirement. In Great Britain, anyone working on gas appliances and fittings must be on the Gas Safe Register for the work they do. A RAMS does not replace that registration, but it should reflect it.

Hazards a plumbing and heating RAMS should cover

Every job and site is different, but a plumbing and heating RAMS will usually need to deal with most of the following.

  • Fire and burns from hot works such as soldering and brazing
  • Scalding from hot water, steam and pressurised systems
  • Legionella and water hygiene when working on stored or stagnant water
  • Confined spaces such as voids, lofts and below-floor areas
  • Gas leaks, carbon monoxide and ignition sources on gas work
  • Electric shock from nearby wiring and bonding
  • Manual handling of boilers, cylinders, radiators and tanks
  • Slips and water spillage, and asbestos in older buildings

Legislation and standards a plumbing and heating RAMS often refers to

  • Gas Safety (Installation and Use) Regulations 1998, for gas work

Your competent person should check which of these apply to your job and make sure the RAMS reflects them.

How to produce a plumbing and heating RAMS in minutes

  2. Tick what is on site. Tell AutoRAMS about access, the public, services, working at height and so on.
  3. Add the site and the team. Name, address, dates and who is working.
  4. Generate and review. Download a branded PDF with your logo, then have your competent person check and approve it before use.

Frequently asked questions

Is a plumbing RAMS different from a heating RAMS?

The format is the same but the content differs. Heating and boiler work brings gas, flues and carbon monoxide into the picture, while general plumbing focuses more on water, hot works and access.

Does the RAMS replace Gas Safe registration?

No. Gas work must be carried out by a Gas Safe registered engineer for the work in question. The RAMS records how the work will be done safely; it does not give anyone the right to do it.

Do I need a RAMS for emergency call-outs?

Emergency work still needs risk assessment. Having generic emergency jobs ready, such as burst pipes or leak repairs, means you can adapt and issue a RAMS quickly instead of working without one.
