Boiler failed, with no heating or hot water? DGN GAS prioritises emergency boiler replacement across Richmond (TW9/TW10) — a small, focused team that moves quickly to fit a like-for-like replacement in riverside and period homes, with the flue and external work done sympathetically. Gas Safe registered. Free quote.
A boiler that’s died in a Richmond home — no heating, no hot water, maybe a leak — needs sorting quickly. If water is escaping, turn the system off and call us, and we get on with fitting a like-for-like replacement.
We won’t promise a specific hour, but a cold home is treated as urgent and, as a small hands-on team, we keep your job moving instead of parked behind a long list.
Because we’re a small, focused team, we can prioritise a failed boiler and move quickly — sourcing the right like-for-like unit, draining down, swapping and recommissioning, usually in a single visit for a straight swap. We fit Worcester Bosch, Vaillant, Baxi and ATAG boilers, every one Gas Safe certified with the manufacturer warranty registered.
If an upgrade suits a larger period house better than a like-for-like, we’ll size it on the spot — and where the old system is sludged, we include a full flush as standard to protect the new boiler.
Richmond is period-home territory — Georgian townhouses and Victorian villas around Richmond Green, Richmond Hill and the river, plus family homes towards Petersham and East Sheen. A lot of it sits within conservation areas (the famous view from Richmond Hill is protected by Act of Parliament), so an emergency replacement still has to respect the building and its setting. We plan the flue route and any external work sympathetically, even at short notice.
Older Richmond houses often run tired or oversized period systems, and riverside properties bring their own quirks; we size the right like-for-like, or where it makes sense a better-matched system boiler and cylinder for a larger home with several bathrooms. The aim is heat back on, done properly, without scarring a period frontage.
From the Georgian terraces around Richmond Green and the period houses climbing Richmond Hill to the family homes of East Sheen, Petersham and out towards Kew, riverside and low-lying properties also need the boiler, flue and any condensate run positioned with flooding in mind — detail we factor in rather than discover later.
Parking and access vary across Richmond — the tight terraces around the Green and the Hill are a world away from the wider family roads of East Sheen — so we plan the approach, protect period floors and staircases on the way in, and route pipework and the flue to suit the house rather than forcing a standard layout onto a characterful home.
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 Richmond
Homeowners across Richmond and south west London call DGN GAS when the heating fails — here’s what they say:
"I had my boiler repaired by DGN GAS in an emergency — they were brilliant. The following year when it broke down again I got Ravinder to replace it. My daughter is about to renovate her property and wants a new boiler. She will be using DGN too."
"The guys from DGN Gas were great. We needed them to replace a Megaflo. They were very courteous and respectful as well as being clean and tidy. They completed the job as requested and made sure everything was working well afterwards. Highly recommend."
