Boiler Emergency

When your boiler fails
and you need it sorted

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.

How We Work

A fast, focused
replacement

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 Specifics

Riverside period homes
& conservation

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.

Powerflushing

Powerflushing
across London

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.

Frequently Asked Questions

Common questions
about Richmond emergencies

We’re in a Richmond conservation area — can you still fit a flue in an emergency?
Yes, done properly. Much of Richmond is conservation area, so the flue and any external work must be sited sympathetically to the period frontage and setting. We plan the route correctly rather than rushing an unsympathetic shortcut.
Our period house has an old oversized system {D} replace or upgrade?
We’ll advise honestly. Sometimes a like-for-like is right; for a larger house with several bathrooms a system boiler and cylinder is often the better long-term fit. You’ll get both options and the costs.
How quickly can you come?
We treat a cold home as urgent and a small team keeps us nimble, but we won’t promise a specific hour we can’t always keep. Your job is prioritised, not parked.
Do you do planned installs too?
Yes — for a planned new boiler, cylinder or full system in Richmond, see our boiler installation service. Same team and standard, just without the emergency.

"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."
