Local insights

Boiler installation in Greenwich: the local picture.

Greenwich boiler installation covers SE3, SE7, SE8, SE9, SE10, SE18, and SE28, ranging from Greenwich and Blackheath Georgian terraces and SE3 and SE9 Edwardian villas to Thamesmead post-war estates and Greenwich Peninsula modern apartments. The Greenwich and Blackheath conservation areas mean period brassware and visible-pipework finishes are specified accordingly, and listed-building consent is needed where work touches a protected facade. A Deptford one or two bed conversion typically suits a 24 to 30 kW Vaillant ecoTEC plus or Worcester Bosch Greenstar 4000 combi; a three-bed Charlton or SE3 villa runs 30 to 35 kW; and four-bedroom Blackheath houses with multiple bathrooms move to a system boiler with a 180 to 210L Megaflo cylinder.

Thames Water across Greenwich is moderately hard, so every install gets a BS 7593 inhibitor dose of Sentinel X100 or Fernox F1 and an Adey MagnaClean Pro2 or Fernox TF1 Omega magnetic filter on the return. Building Regulations Part L makes the install notifiable; Gas Safe lodges within 30 days and the building-control certificate is emailed inside 14 days.

BS 5440 flue clearances (300 mm from opening windows, 600 mm from boundary or facing wall, 2.1 m above pedestrian paving) interact tightly with Blackheath terraces and Greenwich Peninsula balcony stock, so flue routing through internal voids in Part J fire-rated ducting is part of every survey. Combi installs across Greenwich start from £1,800 and system boilers with a cylinder start from £4,500. Worcester Bosch Greenstar 4000 and 8000 Life and Vaillant ecoTEC plus and exclusive ranges carry 10 to 12 years' manufacturer warranty when registered by an accredited installer, with our 12-month workmanship guarantee on top. Survey-to-install slot is one to two weeks for combi swaps and two to three weeks for system upgrades; full back-boiler conversions in Eltham period stock typically take three days on site.

FAQ

Boiler installation in Greenwich: your questions

What size boiler should I install in Greenwich?
Greenwich property stock runs to Georgian terraces in Greenwich and Blackheath, Edwardian villas across SE3/SE9, post-war estates in Thamesmead, modern apartments in Greenwich Peninsula, which drives the kW size we recommend. For a typical Greenwich install: 30 kW combi for 1 bed and studio flats, 35 kW combi for 2 to 3 bed flat conversions and small HMOs, system boiler with 180L+ Megaflo cylinder for any HMO over three bedrooms or any property with two bathrooms drawing simultaneously. We size on a 35 kW per litre per minute flow demand calculation, accounting for simultaneous bathroom-and-kitchen draw in family terraces, and the soft post-treatment water in central London zones. We survey before quoting, we don't size off the existing badge.
Do I need building regulations approval for a Greenwich boiler install?
Every boiler install in Greenwich is a Building Regs Part L notifiable work and we notify Gas Safe (which auto-notifies your local authority) within 30 days of the install. Flue clearances follow BS 5440: 300 mm minimum from any opening window, 600 mm from a boundary or facing wall, and 2.1 m above a paving level for a pedestrian flue. In HMO conversions across Greenwich, Blackheath, Woolwich, multi-storey flue routing through internal voids needs a Part J fire-rated flue duct, and we Gas Safe notify each unit separately if individual combis are fitted per flat. Building control sign-off and Gas Safe certificate are emailed to you within 14 days. CP12 / LGSR landlord certificate available at install for £125 (Greenwich accepts our certs directly).
Which boiler brands do you install most in Greenwich?
Across Greenwich we most commonly fit Worcester Greenstar 4000 and Vaillant ecoTEC pro for HMO conversions, Worcester Greenstar CDi system boilers for cylinder-fed flats. Worcester Greenstar 4000 with a 10-year warranty hits the price-vs-warranty sweet spot for Greenwich standard installs, and Vaillant ecoTEC plus or ecoTEC pro for HMO conversions where landlord parts availability matters. We are a Worcester Bosch Accredited Installer and a Vaillant Advance Installer, which means the full manufacturer warranty (typically 10 to 12 years) is registered at install, not the standard 2-year warranty unaccredited fitters get. We can install other brands (Ideal, Baxi, Viessmann, Glow-worm) on request if you have a preference or a service contract with a specific brand.
What does a boiler installation cost in Greenwich?
Greenwich sits in our Inner London install tier. A standard like-for-like combi boiler install in Greenwich starts from £2,490 including the boiler, flue, magnetic filter (Adey MagnaClean Pro2), system flush, condensate run, and Gas Safe certificate. A system boiler + unvented cylinder upgrade starts from £4,490. All prices exclude VAT. Fixed price quoted after a free survey, we don't add surprises on the day. 12-month workmanship guarantee runs alongside the manufacturer warranty (10 to 12 years depending on brand/model).
How long does a Greenwich boiler installation take?
For a typical Greenwich install we plan one day for a straightforward like-for-like combi swap; two days for a system upgrade with cylinder install; three days for back-boiler removal or full system change. Heating and hot water are off only during the install day itself, and we drain, swap, and refill the system the same day where possible. We protect floors with hardboard runners and cover furniture; we tidy up at the end of each day so the property stays usable. Engineers arrive at 8:30am on the agreed install day with the boiler on the van. Survey to install slot is typically 1 to 2 weeks for combi swaps, 2 to 3 weeks for system upgrades where the cylinder is bespoke-spec.
