Plumber & Heating Engineer in Corby

Reactive Gas, Heating & Plumbing is registered at 9 Rutherford Court, NN17 4SJ — so when you call, the engineer arriving is genuinely local. We work daily across Oakley Vale, Great Oakley, Weldon, Danesholme, Kingswood, Beanfield, Lloyds and the older town centre streets, plus the new estates off Steel Road and Stephenson Way.

The mix of property here is unusual: a strong stock of 1950s/60s steel-town houses, large 2000s+ developments, and a growing number of new-builds on the south edge. Each comes with its own quirks — undersized 22mm gas runs in the older stock, hard-water scale knocking heat exchangers in the newer combis, and pressure-loss issues on the higher-set estates. We see it daily and price for it honestly.

Typical response from booking to engineer-on-site for a Corby emergency is around 45 minutes during working hours and within 2 hours overnight. For installations and servicing, most Corby bookings go in the same week.

We're not a national lead-broker — Reactive is one Corby-based engineer with a small trusted team. Every quote, every visit, every guarantee is direct.

That matters in Corby because we know which streets have shared meters, where the council still owns the gas main, and which new-build developers fitted boilers we'd refuse to install. Local context shortens every job.

Many original Corby New Town houses had 15mm gas runs sized for back-boilers. Modern combis need 22mm — we'll size and re-pipe before fitting, not after the boiler keeps locking out.

Anglian Water in NN18 runs hard. We always fit a scale reducer on installs and offer a low-cost descale on existing combis losing hot-water flow.

Sludge build-up in older copper microbore systems is the usual cause. A targeted power flush usually restores full heat without ripping pipework out.

External condensate pipes and outside taps freeze every January here. We re-route or insulate as part of the call-out so it doesn't happen again.

Town-house developments off Phoenix Parkway often suffer from undersized expansion vessels. We diagnose and replace rather than just re-pressurising weekly.

Older clay drain runs collapse under root pressure. We CCTV survey first and quote a permanent fix, not a quick rod-and-go.
