DGN GAS installs and replaces boilers across Hayes (UB3) — from the 1930s terraces of Botwell and Hayes End to the new canal-side apartments at Hayes Village. Gas Safe registered, Worcester Bosch, Vaillant and Baxi installer. Free no-obligation quotes.
Across Hayes — from the interwar terraces of Botwell, Hayes End and Wood End to the new canal-side homes rising on the old Nestlé and EMI factory sites — 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 UB3 and UB4.
Whether it’s a combi swap in a period terrace, a landlord replacement or a new system in a modern flat, every Hayes install is done to the same standard and left clean and tidy.
Hayes is one of West London’s most varied and fast-changing areas — 1930s terraced and semi-detached houses across Botwell, Hayes End, Wood End and Yeading, alongside thousands of new canal-side apartments at Hayes Village and the Old Vinyl Factory, all now on the Elizabeth line at Hayes & Harlington. The older homes often run tired or oversized boilers, and we right-size a modern combi or a system boiler and cylinder to suit; in the newer flats we handle like-for-like combi replacements within the existing layout.
We do a lot of work for Hayes homeowners, landlords and investors — reliable, well-priced replacements that pass their Gas Safe checks. The area’s older streets near the River Crane sit on low-lying ground, so we route condensate and flues carefully and tidily. We cover all of UB3 and UB4 around Botwell, Hayes End, Wood End, Yeading and the canal, and out towards Harlington and West Drayton.

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.
