DGN GAS was founded by Ravinder Singh and has grown over almost a decade into one of London's most trusted independent gas and heating companies. What started as a commitment to doing things properly has become a business built on that same standard — from the first job to the last.
From the very beginning, the focus has been on quality over volume. Not rushing jobs. Not cutting corners. Not recommending work that isn't needed. Skilled, honest engineering — carried out to a standard our team is proud to put the DGN GAS name to.
That reputation has been built one job at a time — and it shows in the hundreds of five-star Google reviews left by customers who keep coming back, and who send their families our way.
Our team has worked across London's full range of properties — from multi-million pound homes in some of the capital's most prestigious addresses, to the modest terraced house where a young family has just moved in and needs heating they can rely on.
The property changes. The standard doesn't.
Whether it's a Megaflo and underfloor heating installation in a newly renovated home in West London, or a straightforward boiler replacement for a family who simply want warm radiators and reliable hot water — every job receives the same attention, the same care and the same finish.
Complex installations — Megaflo systems, underfloor heating, heat pumps — carried out to the highest specification and finish.
For families who want heating and hot water they can genuinely rely on — without worry, without breakdowns, without a boiler that keeps them up at night.
Efficient boiler installations for smaller spaces, with minimal disruption and a clean, tidy finish.
CP12 certificates, annual servicing and reliable boiler installations for single properties and larger portfolios.
Working alongside architects and developers on new build and renovation projects — complete heating systems from scratch.
Honest advice about your heating system — what's needed, what can wait, and what would make the most difference. No upselling.
We tell customers what they need to hear. If a boiler can be repaired, we repair it. No upselling, no unnecessary work.
Whether it's a multi-million pound home or a one-bedroom flat — every installation receives the same attention, care and quality of finish.
