DGN GAS installs and replaces boilers across Hanwell (W7) — from the Victorian and Edwardian terraces around the village green to family homes near Brent Lodge Park. Gas Safe registered, Worcester Bosch, Vaillant and Baxi installer. Free no-obligation quotes.
Across Hanwell's Victorian and Edwardian terraces and semis — the leafy streets off Uxbridge Road and Boston Road that give this West London ‘village’ its character — DGN GAS replaces ageing boilers and installs modern heating sized to the property. Our Gas Safe registered, F Gas qualified team covers boilers, Megaflo cylinders, underfloor heating, heat pumps and air conditioning right across W7.
From a like-for-like combi swap in a Victorian terrace to a full system in an extended Edwardian family home, every Hanwell install is carried out to the same uncompromising standard.
Hanwell is one of West London’s last Victorian ‘villages’ — predominantly Victorian and Edwardian terraced and semi-detached houses on streets like Church Road, Cuckoo Lane and Golden Manor, alongside newer apartments around the Elizabeth line station. Period family homes like these often still run tired or oversized systems: we right-size a modern combi for a smaller terrace, or a system boiler and cylinder for a larger or extended Edwardian house with more than one bathroom. With the Elizabeth line driving a wave of renovations and side-return and rear extensions across W7, we’re often fitting new heating, underfloor heating and heat-pump-ready systems as part of a refurbishment.
Much of the historic core sits within the Hanwell Village Green Conservation Area — extended to take in Campbell Road, Golden Manor and Hanwell Station — where flue positions and any external units need to be sited sympathetically to the period frontages, something we plan before we quote rather than discover on the day. We cover all of Hanwell including the Village Green, Church Road, Boston Road, the Brent Valley and out toward West Ealing and the Southall border.

If your radiators have cold spots, your system’s noisy, or your boiler keeps cutting out, the usual suspect is sludge and corrosion in the pipework — and a powerflush may be the fix. Often people are told on a service that their system needs flushing, or notice radiators that won’t warm up properly.
We assess the system and carry out the right flush to clear the blockages that wreck efficiency and shorten a boiler’s life. It’s a high-value job we do right across London as a standalone service — and on a new boiler install we always include a full flush of the system as standard. See our powerflush service for what’s involved.

Serving Hanwell
Homeowners across Hanwell and the wider Ealing borough trust DGN GAS for clean, one-day installs — here’s what they say:
"DGN GAS have been working with my firm for years. They've carried out boiler installations, unvented cylinder work and underfloor heating systems using top-quality brands including Vaillant, Worcester Bosch, Baxi and Megaflo. Workmanship and service are consistently excellent."
"Did our boiler and Megaflo installation and installed our powertank pressure booster system. I also got them to come and do my gas safety inspection afterwards. Very professional and I would use them again."
Yes — period terraces need a tidy, well-planned swap. We protect the home, plan the flue and pipework around the original layout, and aim to be in and out in a day for a straight replacement.
Regularly — Hanwell’s Victorian and Edwardian homes are popular for side-return and rear extensions, and we design the heating, and any underfloor heating, around the new layout.
Yes — we work right across W7 and into neighbouring West Ealing, Ealing and Southall, so it’s one local team from install to servicing.
