About On-Tap

Our Story
Built one customer at a time, since 2015.
Who we help
Homeowners across Bedfordshire who want their heating to just work — and to be told the truth when it doesn't. Landlords and letting agents who need reliable CP12 turnaround and tenants who don't ring them on Christmas Day. Families upgrading old systems for modern, efficient ones with smart controls. We're built for the people who'd rather pay once and properly than three times reactively.
What we specialise in
Domestic heating and plumbing — boiler installs, annual servicing, central heating upgrades, bathroom refits, leak detection, and emergency response. We're Worcester Bosch Accredited Installers and Vaillant Advance, which means we install boilers eligible for up to 18-year manufacturer warranties on qualifying systems. We work on all leading boiler brands. We do residential, all day, every day.
Experience depth
Ten years in business, thousands of jobs completed, and a team of Gas Safe engineers who've each been on the tools for over a decade. That depth shows up in fault diagnosis — we've seen most things twice — and in pricing accuracy. Our written quotes don't change halfway through a job because we already know what the job looks like.
Service area
Our base in Westoning, MK45 puts us within 30 minutes of every town we serve: Bedford, Milton Keynes, Luton, Hitchin, Flitwick, Biggleswade, Barton-le-Clay and Stevenage — plus the villages in between. We're a genuinely local team, not a national chain dispatching whoever's nearest. See our full service area →
Mission & Standards
How we work, and what we promise.
We treat every job as if it's the only thing keeping us in business — because for ten years, that's what's kept us in business.
Quality standards
Manufacturer-spec installs. Pressure-tested gas, balanced flow, scale-protected where water demands it. Nothing rushed, nothing cut.
Service philosophy
The engineer who quotes is the engineer who fits — no subcontractors. Same faces on the second visit. Customers know us by name.
Our guarantee
12-month workmanship guarantee on every job. Up to 18-year manufacturer parts-and-labour warranties available on qualifying new boiler installations.
Honest pricing
Written fixed-price quotes before any spanner comes out. No verbal estimates, no deposits on standard installs, no surprise charges.
We turn up
If we book you in for Wednesday morning, we're there Wednesday morning. If we're delayed, you get a call — not a no-show.
Tidy work
Dust sheets down, vacuum out, protective coverings on flooring. Your home should look the same when we leave — except the thing we came to fix.
