Suitable plumbing work
Find a plumber to repair a leaking radiator, replace a valve, move or add radiators, alter heating pipes or work on water-based underfloor heating. Include the number of affected radiators, whether the problem is throughout the property and the type of heating system if known.
Uneven heating may have several causes. You do not need to work out which part is at fault. Describe what you have noticed and let the tradesperson investigate.
Gas boilers need the right engineer
A plumber who is not Gas Safe registered may carry out some water-side work, but work on a gas boiler, gas appliance, gas fitting or the final connection to a boiler must be done by a suitably qualified Gas Safe registered engineer. Check the engineer’s card and the categories of work shown on the back.
Information that helps with a quote
Note the radiator type and approximate size, the floor it is on, whether the room has concrete floors or floorboards and whether pipework is visible. For planned additions, explain the intended room use and whether decorating or floor repairs are part of the request.
