A local engineer who knows 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. A lot of the work here is balancing systems, fixing cold radiators and upgrading tired combis mid-terrace.
InstaGasWorks is based at 37 Mitcham Lane, Streatham - 10-15 minutes from Balham. The patch is kept tight on purpose: it's what makes same-day call-outs possible, and it means your engineer turns up when promised.

Balham questions, answered
How fast can you get to Balham?
InstaGasWorks is based on Mitcham Lane in Streatham, so Balham is typically 10-15 minutes away. In an emergency your engineer can often be with you within the hour. Call 0208 226 0205 and the timing is confirmed 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.
I've had a loft conversion. Can my boiler cope?
A common Balham question. Extra bathrooms and radiators often push an older boiler past what it was sized for. The fix starts with an assessment of your system and a rebalance, then if needed a 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.
