Across Northolt’s interwar and postwar semis — the family streets that grew up around the old village and the Central line — 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 across UB5.

Whether it’s a straightforward combi swap, a landlord replacement or a full system upgrade, every Northolt install is done to the same standard and left clean and tidy.

About Northolt

Heating engineers for
Northolt’s family homes

Northolt is a green, family-friendly part of Ealing built largely between and just after the wars — a mix of private and former-council semis and terraces around the historic green, the 14th-century St Mary the Virgin church and the man-made hills of Northala Fields. Many of these homes are on their original or second boiler; we right-size a modern combi for a typical semi, or a system boiler and cylinder where a family needs more hot water, and sort out tired pipework and controls at the same time.

We do a lot of work for Northolt homeowners and landlords alike — a reliable, well-priced replacement that passes its Gas Safe checks and keeps tenants warm. The homes here usually have good side and rear access, so a swap is typically a clean single-visit job. We cover all of UB5 around Northolt village, Belvue Park, Mandeville and out towards Greenford and Yeading.

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 Northolt

We’ve got an ex-council semi in Northolt — can you fit a new boiler?
Yes — we replace boilers in Northolt’s private and former-council homes every week. We’ll size a modern combi or system boiler to the house and fit it cleanly, with full certification.
I’m a landlord — can you handle a replacement and the gas certificate?
Yes — we do landlord boiler replacements across Northolt and can sort the Gas Safety (CP12) certificate at the same time, with minimal disruption to tenants.
Our boiler’s old but still running — is it worth replacing now?
Often yes — an old non-condensing boiler wastes gas and is more likely to fail in winter. We’ll give you an honest view at the survey rather than push a replacement you don’t need.
Which parts of Northolt do you cover?
All of UB5 — Northolt village, Northala Fields, Belvue, Mandeville and Western Avenue, plus neighbouring Greenford, Yeading and Perivale.

How much does a new boiler cost in Northolt?

It depends on the boiler and the work involved — a straight combi swap is less than a full system change. We give a clear fixed quote after a free survey, with no surprises.

Do you remove the old boiler?

Yes — we remove and dispose of the old boiler and any redundant tanks, and leave everything clean and tidy.

Do you also cover Greenford and Yeading?
