Compare quotes from heating engineers in Bexleyheath, Welling, Sidcup, Crayford and Erith for boiler replacement, servicing, repairs and radiators.
Bexleyheath and the rest of the borough of Bexley grew around the railway in the 1930s, and street after street of semis and short terraces in Welling, Barnehurst and Blackfen still date from that era. Many have been extended at the back or into the loft, and most rely on a gas boiler that has been replaced at least once.
Describe what you need – a new boiler, an annual service, a breakdown repair or extra radiators – and compare quotes from engineers who work across south-east London and north-west Kent.

Inter-war semis with extended systems
A typical Bexley semi began with a regular boiler, an airing-cupboard cylinder and tanks in the loft. Loft conversions often removed the tanks' natural home, which is one reason so many owners have switched to combis. If you're planning a conversion, ask about the heating at the same time – the loft room will need a radiator, and the boiler may need to change.
Rear extensions are the other common factor. Radiators added on long pipe runs can heat slowly, and the whole system may need balancing so the new room gets its share.

Pricing a boiler or heating job in Bexleyheath
Two boiler quotes for similar homes in Bexleyheath can differ more than you might expect. It often comes down to things like these:
- Planned building work: coordinating with a loft conversion or extension can affect timing and pipe routes.
- Conversion scope: removing tanks and a cylinder adds a day or more to a boiler swap.
- System balance: long pipe runs to extensions may need extra valves or a pump check.

Bexleyheath boiler and heating FAQs
Should I change my boiler before a loft conversion?
Often it makes sense. Loft tanks usually have to go, and a combi or a system boiler with an unvented cylinder removes the need for them. Plan the heating with your conversion company and engineer together.
Why is my extension colder than the rest of the house?
The radiator may be undersized for a room with lots of glass, or it may be at the end of a long pipe run. An engineer can check its output and balance the system.
Will an engineer from Bexleyheath travel to Dartford?

Boilers and heating systems across London
London's heating work is shaped by its homes: converted period houses, mansion blocks, ex-council blocks and new-build developments, many with the boiler squeezed into a kitchen cupboard. Flue routes can be tricky in flats and tight terraces, parking and access add time to every visit, and some newer developments run on communal or electric heating rather than an individual gas boiler.
For anything involving gas, only use an engineer on the Gas Safe Register. Their ID card lists the types of gas work they're registered for, and you can confirm their registration online. How to check an engineer.
