Boiler repair in Swansea
Describe the fault and we pass it to Gas Safe registered engineers who cover your Swansea postcode.
Four in five Swansea homes heat with a mains gas boiler and nothing else. When one fails in January, there is no back-up, so it helps to know which faults you can clear yourself and which need an engineer straight away.

Gas smell or carbon monoxide alarm
Leave the boiler off, open doors and windows and phone the National Gas Emergency Service free on 0800 111 999. If anyone feels dizzy, sick or has a headache, get them into fresh air and seek medical help. Don't use the boiler again until a Gas Safe engineer has checked it.
Quick checks first
Check the pressure gauge. If it reads below 1 bar, top it up using the filling loop and our boiler pressure guide, then reset. If it keeps dropping, there is a leak somewhere that needs an engineer.
Swansea's hillside streets catch cold easterly winds in winter. A condensate pipe running down an exposed outside wall can freeze and shut the boiler down. Thaw it with warm water from a jug, then press reset.
What usually goes wrong
Because Swansea's water is soft, scaled-up heat exchangers are less common than in hard water areas. Faults here tend to be worn parts: fans, pumps, diverter valves, ignition electrodes and pressure sensors. Sludge from old steel radiators is the other big cause, especially in houses with original 1960s or 1970s pipework.
Read out the fault code and the boiler model when you book. The engineer can then bring the most likely part.
For contract-holders
If you rent, your landlord is responsible for repairing the heating and hot water. Report the fault in writing, and if a council or housing association home is without heating, use their emergency repairs line.
Swansea homes and what they need
Hillside Victorian and Edwardian terraces
Pipework in these houses has often been added to piecemeal over decades. Leaks under floors cause slow pressure loss, so mention how often you top up.
Interwar and post-war semis
If you have a cylinder and a regular boiler, tell the engineer whether you have lost heating, hot water, or both. A failed motorised valve is a common culprit.
Waterfront and city-centre flats
Some flats have electric heating rather than gas. If yours has a heat interface unit or electric boiler, say so, as a gas engineer may not be the right trade.
Areas covered
Engineers who cover Swansea work across areas including Sketty, Uplands, Mumbles, Killay, Morriston, Townhill, Brynmill, Gorseinon, Pontarddulais and Clydach.
Questions people in Swansea ask
My Swansea boiler is 15 years old. Repair or replace?
If it's a simple part and the boiler has been serviced, repair is usually cheaper. If the heat exchanger has failed, compare the quote with our new boiler cost guide.
