North London Gas Engineers

Your local gas specialists — based here, working here.

N4 Gas has been serving North London homeowners, landlords and businesses since 2006. We started as a one-man band in the N4 postcode — hence the name — and we've grown steadily by doing good work and letting that speak for itself. Our engineers are based in North London and know the area: the older housing stock in Highgate and Islington, the Victorian terraces of Crouch End and Stroud Green, the new-builds around Tottenham Hale and Haringey, the converted flats across Hackney and Stoke Newington.

Gas engineering in North London has its quirks. Older properties often have gravity-fed open-vented systems, undersized gas pipework and boilers in unusual locations. We've seen every configuration going — and we know how to work with them safely and efficiently. When you call us, you speak to a team that actually knows your area.

Why local matters

We know North London housing stock inside out.

North London properties span every era of British housing — from Edwardian townhouses in Muswell Hill to 1970s council blocks in Wood Green, Victorian conversions in Holloway to new-builds in Tottenham and Meridian Water. Each type presents its own heating challenges. Older gravity-fed systems, limited boiler access, undersized gas pipework, and the specific requirements of listed buildings are all things our engineers deal with daily. When you call us, you're not talking to a national call centre allocating the nearest available engineer — you're talking to a team based in North London, who have been working these streets for nearly two decades.

24hr Emergency Cover Across North London

Heating fails don't wait for office hours. We have an engineer on call around the clock, every day of the year — including bank holidays. If your boiler breaks down at midnight in Islington or your heating fails on Christmas Day in Barnet, we're still available. Call 0208 050 4729 — there's always someone there.

Extensively. North London has a large proportion of Victorian and Edwardian housing, and many of these properties have older heating systems — gravity-fed open-vented systems, solid floor pipework, undersized gas supply pipes and boilers in unusual locations. Our engineers are highly experienced with older systems and know how to work with them safely and cost-effectively.

Yes — CP12 gas safety inspections and certificates are one of our most common services for landlords across North London. We cover properties from single flats in Islington to large HMOs in Haringey.
