Word of mouth,in writing.

Replaced our 18-year-old Potterton with a new Worcester. Fixed-price quote, work done in a day, dust sheets everywhere, even hoovered up before leaving. Sounds basic but it's so rare. Highly recommend.

Burst pipe under the kitchen sink on a Sunday. Aidan was on site within an hour, capped it, came back Monday and did a proper repair. Saved our weekend. Honest pricing too.

Manage 14 rental properties across Luton. On-Tap has handled my CP12s for three years — same-day certificates, auto reminders, one invoice. Removed a real headache from my life.

Full bathroom refit in our Victorian terrace. Project managed end-to-end — tiler, electrician, plumber, decorator. Stayed on quote, finished on time, the result is gorgeous.

Sixth annual service with On-Tap. Same engineer turns up, knows the system, in and out in 45 minutes. Never had a single issue with a boiler they installed.

Whole house re-pipe and new radiators on a new-build that the developer had set up badly. Cold rooms, noisy pump. Aidan recommissioned and rebalanced everything — totally transformed.

Pressure dropping on the boiler every few days. Two other engineers had 'tried things' and charged me each time. Aidan diagnosed a failing expansion vessel in 20 minutes, replaced it, done.

Long manufacturer warranty, scale reducer fitted, smart thermostat set up, all paperwork emailed before the engineer left. This is what professional looks like.

Smelled gas in the kitchen — they prioritised the visit and were here within 90 minutes. Tracked it to a worn cooker connection. Replaced same day, certificate issued. Genuinely reassuring.

Service to manufacturer spec, full service record stamped for our new-build warranty. Friendly, on time, fair price. Won't go anywhere else.

Honest, fast and professional. Issued CP12 the same morning, emailed everything I needed for the agent. No fuss.

No hot water on a freezing weekend. Aidan walked me through an isolation valve over the phone to stop it leaking, then came out next morning. Real human service.
