What Customers Say
After The Engineer
Leaves The Driveway.

Carl and the team replaced our 18-year-old Worcester with a new combi in a single day. Fixed price, no surprises, house warm again by tea time. Cleanest install I've ever had, the lads even hoovered the loft.

Burst pipe under the floorboards at 11pm on a Sunday. Reactive answered first ring, engineer here inside 70 minutes, isolated and repaired same night. Couldn't fault them.

Vaillant locking out repeatedly. Engineer diagnosed a failed PCB on the first visit, ordered the part, back the next morning to fit. Fixed cost agreed before any work, exactly what was quoted.

Radiators cold at the top, hot at the bottom for years. Reactive power-flushed the whole system in a day, balanced every rad and dosed the inhibitor. House is properly warm for the first time in winters.

Booked an annual service after switching from another company who kept missing appointments. Reactive turned up exactly when they said, full combustion analysis, sent the report by email. Refreshing.

Genuinely OFTEC-registered, unlike the last lot who 'sort of' did oil. Nozzle, filter, electrodes, combustion test, tank check, all done properly. Will use again.

Quote was £400 less than British Gas for a better-spec Worcester with a 10-year warranty. Install was a single day, smart Hive control included, finance approved the same evening. Outstanding.

Blocked drain into the river side of the property, CCTV survey identified roots, jetted and patch-repaired in one visit. Honest, no upsell, fair price.

Off-grid LPG property. Reactive are the only local lot I've found who are properly qualified on LPG and don't just refer the work out. Annual service done, regulator and pigtails replaced.

Run a portfolio of 14 rentals across LE postcodes. Reactive issue same-day digital CP12 certificates and direct-bill us monthly. Total game-changer compared to chasing certificates around.

Wanted a Nest setup with our existing boiler. They confirmed compatibility before charging anything, fitted it in 90 minutes and walked me through the app. Genuinely helpful.

Pressure dropping daily for months, three other plumbers just topped it up. Reactive used thermal imaging, found a pinhole under the kitchen floor in 40 minutes, fixed and signed off. Should've called them first.
