Boiler failed, with no heating or hot water? DGN GAS prioritises emergency boiler replacement across Kensington (W8) — a small, focused team that moves quickly to fit a like-for-like replacement, handling the freeholders, managing agents and conservation rules that come with the area’s mansion blocks and period homes. Gas Safe registered. Free quote.
A boiler that’s failed in a Kensington flat or townhouse — no heat, no hot water, maybe a leak — won’t wait for a slow callout. Turn the system off if water is escaping and call us, and we move straight to fitting a like-for-like replacement.
We won’t give a stopwatch promise, but a cold Kensington home is treated as urgent, and a small hands-on team means your job keeps moving.
Being a small, focused team lets us prioritise a dead boiler — sourcing the right like-for-like unit, draining, swapping and recommissioning, usually in a single visit for a straight swap. Worcester Bosch, Vaillant, Baxi and ATAG fitted, Gas Safe certified, warranty registered.
Where the old system is full of sludge we’ll point it out — a fresh boiler on a dirty system won’t last — so we include a full flush as standard.
Kensington is mansion blocks, stucco terraces and period townhouses around Kensington Square, the Phillimore estate and the High Street — almost all within Royal Borough conservation areas, much of it listed or under Article 4. In a managed block, replacing a boiler means freeholder or managing-agent consent, booked access and protection of the common parts; we handle that liaison quickly so the building’s rules don’t leave a flat cold for days.
On period and listed frontages the flue route is restricted — it has to be sited compliantly and out of sight on a protected facade. We plan that route properly before we start, so the replacement is safe, consented where required and sympathetic to the building.
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 Kensington
Homeowners across Kensington and 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."
"Have used DGN GAS a few times now. They installed a boiler at my parent's house and I had a boiler and underfloor heating installed at my house. Very happy with everything."
