Boiler repair in Croydon
Plenty of interwar homes in Croydon still have the original system layout, with a more recent boiler connected to it. The mix leads to faults that keep coming back, and a new boiler on its own will not cure them.

Boiler repair in Croydon
- Modern boilers connected to the pipework of the original system
- Faults that keep coming back because of sludge in an ageing circuit
- Power flushing when a repair on its own will not last
Croydon’s 1930s semis and estates still hold a fair number of back boilers, fitted behind a gas fire in the front room when central heating first arrived. They can often be repaired, but some of their parts are no longer made, so the first job is finding out whether the part exists. Houses that have moved on usually have a combi in the kitchen or a system boiler with the cylinder kept upstairs. Above the shops in the town centre, the converted flats mostly run a compact combi in a cupboard, sometimes with a flue out through a flat roof or a shared rear wall, which brings the freeholder in if anything external has to change. The towers are another matter again, with communal plant that is the building’s responsibility. Croydon water is hard, so combis here scale up on their hot water heat exchanger. Suburban streets generally have room outside; near the centre it is car parks and loading bays.

Questions we often get
Do you work in Croydon?
We do. Croydon falls within Croydon, covering the CR0, CR2, SE25, SW16 postcodes, and our engineers are out across Greater London from our Fulham office every day.
My boiler is new. Why does it keep failing?
Often the system was not cleaned out when the boiler went in. Decades of debris from the old pipes then collect in a modern unit built to far tighter tolerances. A flush tends to cure what a third repair cannot.
I still have a back boiler behind the gas fire. Can you repair it?
Often, yes, if the failed part can still be sourced, such as a thermocouple, a gas valve or a control. Plenty of Croydon semis kept theirs when the rest of the house was modernised. The catch is that parts for some older back boilers are no longer made, and then repair stops being an option. We check availability before quoting, and if replacement is the only answer we explain what moving to a wall-hung boiler would involve.
How much will it cost?
Before an engineer starts, you are given a price for the job. Should something hidden in a wall change what is needed, we stop and discuss it with you first, instead of pressing on and sending the bill later.
