Local engineers who know Wallington
Like much of the old Beddington and Wallington area, SM6 is dominated by inter-war semis - many with conservatories and extensions that added radiators to systems never designed for them. Balancing, power flushing and right-sizing replacement boilers are our bread and butter here.
InstaGasWorks is based at 37 Mitcham Lane, Streatham - 20-25 minutes from Wallington. We keep our patch tight on purpose: it's how we manage same-day call-outs and turn up when we say we will.

Wallington questions, answered
Which parts of Wallington do you cover?
All of SM6 - central Wallington, South Beddington, Roundshaw and the borders with Carshalton and Croydon. We're 20-25 minutes away, based in Streatham.
My radiators upstairs stay cold in Wallington - what's wrong?
Cold upstairs radiators usually mean trapped air or a system balance problem; cold downstairs usually means sludge. Either way it's a quick diagnosis on site - radiator investigation visits are £60-£80 and we'll tell you plainly whether a bleed, rebalance or power flush is the real fix.
Do you do landlord gas certificates in Wallington?
Yes - CP12 landlord gas safety certificates are £80 with extra appliances at £30 each, with certificates emailed the same day. We can add a boiler service to the same visit for £100, so both jobs are done in one appointment.
How much is a boiler service in Wallington?
A basic boiler service in Wallington 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.
How much does a new boiler cost in Wallington?
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 Wallington homes free of charge and give a written quote before anything is booked.
