Local engineers who know Morden
Much of Morden was built in the 1930s, and plenty of homes still run heating systems extended and patched over decades - microbore pipework, old radiators and boilers well past their prime. We're specialists in bringing these systems up to date: power flushing, radiator upgrades and correctly sized modern boilers.
InstaGasWorks is based at 37 Mitcham Lane, Streatham - 15-20 minutes from Morden. We keep our patch tight on purpose: it's how we manage same-day call-outs and turn up when we say we will.

Morden questions, answered
Do you cover the whole of Morden?
Yes - Morden town centre, Morden Park, Lower Morden and the St Helier estate. All of SM4 is 15-20 minutes from our Streatham base.
Our 1930s house has cold radiators downstairs. Can you help?
That's one of our most common Morden call-outs. Decades of sludge build-up in older systems restricts flow, especially on ground floors. A power flush (£580-£820 depending on radiator count, with chemicals and magnetic filter included) usually restores full heat - we'll confirm the right fix after a look at your system.
Can you replace a very old boiler in Morden?
Yes, including back boilers and floor-standing units in older SM4 homes. A combi swap starts from £2,500; converting from an old conventional setup is quoted after a free survey, since pipework and flue routes vary house to house.
How much is a boiler service in Morden?
A basic boiler service in Morden is £120 - gas tightness test, flue gas analysis, controls and system pressure checks, condensate trap cleaned and the expansion vessel recharged. A full service, which adds a strip-down and internal clean, new seals and genuine manufacturer parts, is £220. Annual servicing keeps your manufacturer warranty valid.
