Boiler Installation in Bexley

Bexley is the most architecturally consistent borough we work in, and that consistency is genuinely useful to a customer. It is overwhelmingly interwar suburban London: semi-detached houses built through the 1920s and 1930s along the railway lines and the Sidcup by-pass, which opened in 1928. Bexleyheath, Sidcup, Welling and Blackfen are made of them. When we quote a boiler installation in Bexley we usually know the layout of the house before we walk in.

What that means in practice is that one job dominates: converting an original gravity-fed system, with a hot water cylinder in the airing cupboard and a cold tank in the loft, over to a modern combi. Done properly it frees a cupboard, clears the loft, and removes the two things most likely to leak through a ceiling. Done badly, by someone who did not check the incoming main first, it produces a shower that runs cold whenever the kitchen tap is on. The difference is a flow rate test that takes ten minutes at the survey.

Bexley also has something inner London does not, which is off-street parking on most streets and driveways on many. That sounds trivial and it is not. It means an engineer arrives with the van at the house rather than three streets away, and a boiler installation in Bexley genuinely does tend to finish inside the day more reliably than the same job in Greenwich or Wimbledon.

Local Detail

Property Types Across Bexley

Bexley’s stock is more uniform than most of London, which makes the exceptions worth naming.

Interwar Semis (the Majority)

Bexleyheath, Welling, Sidcup, Blackfen and Barnehurst. Three-bed semis, cavity walls, a bathroom over the hall, an airing cupboard and a loft tank. Original systems were gravity-fed and many have had a back boiler at some point. These are the houses where a combi conversion makes the most difference, provided the mains supply supports it.

1930s Chalet Estates

The Willersley Avenue and Braundton Avenue conservation area in Sidcup, part of the old Smith's Hollies Estate, and similar 1930s development through Blackfen. Larger and better detailed than the standard semi, often with rooms in the roof, which changes where pipework can run and rules out the usual loft route.

Victorian & Village Stock

Old Bexley village, Crayford, Erith and Northumberland Heath. Older, mostly solid-walled, higher heat loss and frequently extended more than once, so the heating system has been added to rather than designed. These are the properties where sizing off the old boiler produces the wrong answer most often.

Post-War & Riverside Estates

Thamesmead, Belvedere, Slade Green and the Erith riverside. A mix of system boilers, older electric heating and properties converted from communal systems. Long pipe runs and undersized radiators are common, and getting a modern boiler to actually condense usually means upsizing a couple of them.

Worth Knowing

What’s Different About Bexley

Fewer planning constraints than the inner boroughs, but the age profile of the housing brings its own set of things to check.

16 Conservation Areas

Bexley has sixteen conservation areas, a modest number for a London borough. The ones that most often affect a boiler installation are Old Bexley Village, Danson Park, Upton in Bexleyheath (home to William Morris's Red House), Blendon, Lamorbey and Crayford. Inside them a flue cannot go on the principal elevation or a side elevation fronting a highway. Outside them, which is most of the borough, permitted development normally covers it.

Combi Conversions & Mains Flow Rate

The most common job in Bexley is taking out a cylinder and loft tank and fitting a combi. The single thing that decides whether that is a good idea is the flow rate at your kitchen tap, measured in litres per minute. Below about twelve, a combi will struggle to run a shower and anything else at once. We measure it before we recommend, not after we install.

Hard Water & Back Boiler Legacy

Bexley shares London's hard water, and a lot of its stock has carried a back boiler or an open-vented system for decades, which means years of sludge sitting in the radiators. Fitting a new boiler onto an unflushed system is the fastest way to void its warranty. Every installation we do here includes a proper power flush or chemical clean, a magnetic filter and the right inhibitor dose.

Access Is Easier Here

Driveways and off-street parking are the norm across most of the borough, and controlled parking zones are far less widespread than in inner London. Our vans are ULEZ compliant, which covers all London boroughs including Bexley. In practice it means we can usually get the van, the new appliance and the old one in and out without the access planning an inner-London job needs.

Common Questions

Boiler Installation in Bexley FAQ

Which parts of Bexley do you cover?
All of it. That is DA5 Bexley and Albany Park, DA6 and DA7 Bexleyheath and Barnehurst, DA8 Erith, DA14 and DA15 Sidcup and Blackfen, DA16 Welling, DA17 Belvedere, DA18 Erith Marshes, DA1 around Crayford, and the parts of SE2 and SE28 that fall inside the borough. Call 07538 192738 if you are near a boundary and want it confirmed.
Can I convert my Bexley semi from a cylinder to a combi boiler?
In most cases yes, and it is the single most common job we do in this borough. It removes the hot water cylinder from the airing cupboard and the cold tank from the loft, which gives you both back and takes away the two components most likely to leak. The one thing that decides it is the flow rate on your incoming main. We measure it at the survey, and if the number does not support a combi we will tell you so and quote a system boiler with an unvented cylinder instead.
I have a back boiler behind the fire. Can it be replaced?
Yes, and it should be. Back boilers are typically forty to fifty per cent efficient against ninety-plus for a modern condensing boiler, and parts for most of them are long discontinued. The replacement usually means relocating the boiler to the kitchen or a utility space, capping and making safe the old fireplace position, and running a new flue. It is a bigger job than a straight swap and we price it as one rather than surprising you halfway through.
How long does a boiler installation take in Bexley?
A straight combi-for-combi swap is normally one day. A conversion from a cylinder and loft tank system to a combi is usually one long day or two, because the old tank and cylinder have to come out and the pipework has to be reconfigured. A back boiler removal with a relocation is two days. We give you the number at the quote and we stick to it.
Do I need planning permission for a boiler flue in Bexley?
Usually not. Most of the borough sits outside a conservation area, so a new flue falls under permitted development. The exceptions are Old Bexley Village, Danson Park, Upton, Blendon, Lamorbey and Crayford, plus any listed building anywhere in the borough. In a conservation area the flue cannot go on the principal elevation or a side elevation fronting a highway. We check your address before quoting.
How much is a boiler service in Bexley?
£79 for an annual service, £69 for a landlord CP12 gas safety certificate. That is the visit, not a call-out charge with the work billed on top. If the service finds a fault we quote the repair separately and you decide whether to proceed.
Do you do landlord gas safety certificates in Bexley?
Yes, at £69 per certificate, and we can combine it with the annual service on the same visit so the tenant only has to be in once. If you have several properties across Bexley and the neighbouring DA postcodes, tell us when you book and we will group the visits into a run rather than charging you as separate jobs.
Can you get to an emergency in Bexley the same day?
For a total loss of heating or hot water, usually yes if you call in the morning. Bexley is inside our normal working area, and access here is easier than most of London, which genuinely helps. Ring 07538 192738 rather than using the form if the boiler is down.
