DGN GAS installs, services and repairs boilers across Greenford from our base in Greenford, which is close enough that a call in the morning can often be a visit the same day. Most of the homes we work in here are 1930s semi-detached and terraced houses, where the boiler has usually been moved or replaced at least once over the years, often when a kitchen was redone or an extension went on, and a couple of our recent Greenford jobs came from exactly that.

We are Gas Safe registered and F Gas qualified, and cover boilers, Megaflo cylinders, underfloor heating and air conditioning, so one team can look after the heating from the first installation through to the annual service years later.

Recent Work

Greenford, UB6

Vaillant combi flue rerouted where it ended too close to a first floor window. The new flue runs horizontally over the extension roof, supported from the wall behind it, with a metal, fire-rated inspection hatch so the joints can be checked. Vaillant confirmed the design in writing before we started, October 2026.

Greenford

Gas leak found and repaired in a wall void after the pipe was caught by a drill while air vents were being fitted. The emergency service had capped the supply, so we replaced the damaged section in a very tight space, tested it with leak detection fluid and a gas sniffer, and put the gas back on, June 2026.

Common Questions

Boiler installation
in Greenford

How quickly can you get to Greenford?
We are based in Southall, a few minutes down Greenford Road, so Greenford is one of the easiest areas for us to cover. For a new boiler we can usually arrange the free survey within a few days, and most installations are booked within the week.
The emergency service capped my gas. What happens now?
The emergency service makes the supply safe by capping it, and that is where their visit ends. A Gas Safe registered engineer then has to find the leak, repair it and test the installation before the gas can go back on, which is what we did for a Greenford homeowner in June 2026. There is more on this in our guide to gas leak checks.
Which parts of Greenford do you cover?
All of Greenford, including Greenford Broadway, Greenford Green and the roads around Horsenden Hill, and across into Perivale and Northolt.
How does a boiler quote from DGN GAS work in Greenford?
We can give a rough price over the phone, then we visit for a free home survey. After the survey you get a written quote that names the exact boiler and materials and sets out the work, at a price that does not change. There is no obligation. If you are comparing quotes, see what to check on a boiler quote.
