Local engineers who know Balham
Balham's housing is classic Victorian terrace territory, much of it extended and loft-converted. That means long pipe runs, radiators added over the years, and boilers working harder than they were sized for. We spend a lot of time here balancing systems, fixing cold radiators and upgrading tired combis mid-terrace.
InstaGasWorks is based at 37 Mitcham Lane, Streatham - 10-15 minutes from Balham. We keep our patch tight on purpose: it's how we manage same-day call-outs and turn up when we say we will.

Balham questions, answered
How fast can you get to Balham?
We're based on Mitcham Lane in Streatham, so Balham is typically 10-15 minutes away. For emergencies we can often be with you within the hour - call 0208 226 0205 and we'll confirm before you book.
Do you cover the whole of SW12?
Yes - Balham High Road, Hyde Farm, the streets around Wandsworth Common and Tooting Bec Common, and everywhere in between.
We've had a loft conversion - can our boiler cope?
A common Balham question. Extra bathrooms and radiators often push an older boiler past what it was sized for. We can assess your system, rebalance it, and if needed quote for a correctly sized replacement - combi swaps start from £2,500.
How much is a boiler service in Balham?
A basic boiler service in Balham 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.
