Local engineers who know Dulwich
Dulwich's housing runs from Victorian workers' terraces around Lordship Lane to substantial detached homes near the Park and College. Period properties mean original pipework, cast-iron radiators worth keeping, and boilers hidden in cellars and outriggers. We work sympathetically on all of it, and we're happy quoting for conservation-minded upgrades.
InstaGasWorks is based at 37 Mitcham Lane, Streatham - 15-20 minutes from Dulwich. We keep our patch tight on purpose: it's how we manage same-day call-outs and turn up when we say we will.

Dulwich questions, answered
Do you cover East Dulwich as well as Dulwich Village?
Yes - SE22 (East Dulwich and Lordship Lane) and SE21 (Dulwich Village, West Dulwich borders and around the Park). Both are 15-20 minutes from our Streatham base.
Can you work on the heating in a period Dulwich property?
Yes - much of our Dulwich work is in Victorian and Edwardian homes. We can repair and balance older systems, keep original radiators in service where they're sound, and route new pipework discreetly when upgrades are needed.
How much is an emergency plumber in Dulwich?
An emergency water leak call-out is £150, day or night. We'll talk you through shutting off the water at the stopcock while an engineer is on the way, which often limits the damage before we arrive.
How much is a boiler service in Dulwich?
A basic boiler service in Dulwich 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 Dulwich?
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 Dulwich homes free of charge and give a written quote before anything is booked.
