What Customers Say
“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.”
James P.
Blaby · Emergency Plumbing · 28 February 2026
“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.”
Helen W.
Birstall · Boiler Repair · 18 February 2026
“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.”
Rob T.
Syston · Power Flushing · 04 February 2026
“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.”
Priya K.
Thurmaston · Annual Service · 22 January 2026
“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.”
