Boiler repair in Bexleyheath, Sidcup and Welling: what happens when you ring
We answer, day and night. We'll ask what the boiler is doing, where in Bexleyheath, Sidcup and Welling you are and whether you have a hot-water cylinder.
Which parts of Bexleyheath, Sidcup and Welling do your gas engineers cover?
Every part of Bexleyheath, Sidcup and Welling, at any hour, from Welling and Bexleyheath in the north to Sidcup and Longlands in the south. By postcode district, the three towns divide up like this:
- DA6 and DA7: Bexleyheath and Crook Log
- DA16: Welling, East Wickham and Falconwood
- DA14 and DA15: Sidcup, Longlands, Lamorbey and Blackfen
Some streets on the edges have DA5 or SE9 postcodes. The rest of the borough of Bexley is ours too, Erith, Crayford and Old Bexley among it. If your road sits near the borough line, ring us with the postcode and we'll tell you.
What kind of boiler do homes in Bexleyheath, Sidcup and Welling have?
Semi-detached houses are the commonest home across Bexleyheath, Sidcup and Welling, and Welling's streets have the most of all. Blackfen and Falconwood add a good many terraces, while the Sidcup and Longlands wards have far more flats than the rest. A house like these could have a combi or a boiler with a hot-water cylinder. The cylinder is one of the things we'll ask about when you ring.
In the Sidcup and Longlands wards, more homes are heated by electricity alone than in the other five. Our engineers repair electric boilers as well as gas ones. Whichever heats your home, ring us, and we'll say on the call whether it's one for our engineers.
How hard is the water in Bexleyheath and Sidcup?
The water in Bexleyheath and Sidcup is very hard. Thames Water's reports for 2025 put every sample from its Bexleyheath supply zone in its very hard band, the top of the scale it uses. Every sample from its Sidcup and Elmstead Wood zone was in that band too.
A replacement combi is where the hardness counts. The building regulations' guidance asks for a new combi's hot water to be protected from scale wherever the water is harder than 200 mg/l. Both zones were far past that, so scale protection belongs on any new combi fitted here.
Whatever has stopped your boiler, the call is the place to start. Ring us, and we'll say when an engineer can come.
Where can a new boiler flue go in a Sidcup or Bexleyheath conservation area?
In a Sidcup or Bexleyheath conservation area, a new boiler flue needs planning permission if it faces the road from a house's front or side. Bexley Council's appraisals for most of these areas also ask for heating flues and vents to be kept to a minimum. They should go where they won't harm the look of the house or the street.
Sidcup's conservation areas are:
- Christ Church
- The Green
- Halfway Street
- The Hollies
- Longlands Road
- Old Forge Way
- The Oval
- Willersley and Braundton Avenues
Bexleyheath has Red House Lane. Where a replacement boiler's flue has to move, these rules come into play. When a new boiler makes more sense than a repair. Ring us for a quote on a new one. Its survey visit costs nothing.
Bexley's flue guidance, and the planning rule behind it
Every conservation area in Bexley has an appraisal and management plan. Each of Sidcup's appraisals, apart from Old Forge Way's, lists heating system flues and vents among the minor additions to keep to a minimum. Red House Lane's does too. Aerials, satellite dishes, burglar alarms and CCTV cameras are on the same lists. Each should go where it's needed, in places and ways that won't harm the building or the area.
The planning rule itself is national. The General Permitted Development Order 2015 grants a house permission for a new or replacement flue with no application, on conditions. In a conservation area, that permission stops short of a wall or roof slope fronting a road, at the house's front or side. The Order's permission is for houses, so a flat has none. Old Forge Way and Red House Lane also have Article 4 directions, which bring other outside alterations under planning control.
