Local engineers who know Streatham
We know Streatham's housing stock street by street - the big Victorian semis off Streatham Common, the mansion-block flats along the High Road, and the 1930s homes towards Streatham Vale. Sludged radiators and ageing back-boiler conversions are local specialities, and we've replaced more SW16 combis than we can count.
InstaGasWorks is based at 37 Mitcham Lane, Streatham - right in the heart of SW16. We keep our patch tight on purpose: it's how we manage same-day call-outs and turn up when we say we will.

Streatham questions, answered
01Where exactly are you based in Streatham?
Our base is at 37 Mitcham Lane, SW16 6LJ - between Streatham High Road and Tooting. For most Streatham addresses we can be with you faster than anyone who has to cross half of London first.
02Do you cover Streatham Hill and Streatham Vale too?
Yes - all of SW16: Streatham Hill, Streatham Common, Streatham Vale and the Furzedown borders. Norbury, which shares SW16, has its own page too.
03What does a boiler service cost in Streatham?
A basic boiler service - gas tightness test, flue gas analysis, controls and pressure checks and a cleaned condensate trap - is £120. A full service, with the boiler stripped down and cleaned internally and new seals fitted, is £220. Being local, we can usually fit Streatham services around your day rather than giving you a vague all-day window.
04How much does a new boiler cost in Streatham?
A straightforward combi-for-combi swap starts from £2,500, and that price includes a powerflush, a magnetic filter, a limescale reducer, one free heating control and up to 12 years warranty. Converting an older conventional system costs more depending on pipework and flue routes, so we survey Streatham homes free of charge and give a written quote before anything is booked.
