New combi, system, and regular boiler installation with manufacturer warranty.
* Estimates only, not a quote — typical figures from recent jobs. Your engineer confirms the exact price before any work starts.
A new boiler is the single biggest upgrade you can make to your heating bills and comfort — but only if it's sized, sited and installed properly. Our matched installers are Gas Safe registered, manufacturer-accredited where it matters, and they quote fixed prices before any work begins.
Tell us about your property with our interactive form and we'll match you to local installers who've done the same job on houses like yours. Every install includes commissioning, a full system flush where needed, and the paperwork (benchmark certificate, building regs notification) your warranty depends on.
Survey & sizing: heat-loss calculations (not guesses) to pick the right output for your home.
Removal & disposal of the old boiler, including safe disposal of old pipework.
Installation: new boiler, flue, condensate and controls to Gas Safe and manufacturer standards.
Commissioning: system flush, inhibitor, full test and demonstration — plus registering the install with Gas Safe and notifying building control.
Handover: benchmark logbook, warranty registration, and a walkthrough of your new controls.
Cheap installs skip the flush, the paperwork and the commissioning — and warranties get voided. Compare 2–3 fixed quotes with the same spec.
If you're planning an extension or conservatory, make sure it won't foul the boiler flue position — moving a flue is a separate job.
A magnetic filter and inhibitor at install time keep sludge out and protect your warranty for years.
Manufacturer warranties (5–10 years on most brands) only count if the install is registered — do it on day one.
You must have every gas appliance, flue and pipe checked annually by a Gas Safe registered engineer and give tenants the CP12 record within 28 days of the check (and before new tenancies start). It's a criminal offence not to. Book your annual service early — engineers get booked out in winter, and an expired certificate can invalidate insurance.
As a landlord you must keep the property's water, heating, sanitary and drainage systems in good working order and fix them promptly when they fail. You're responsible for structural repairs, the boiler and heating system, plumbing and electrics. Tenants should report faults in writing — and you should respond fast, because a small leak left unattended becomes a big claim.
Eligible households can save hundreds on heating upgrades through the government's ECO4 scheme — and we're bringing grant support to Plumbline soon. Register your job now and we'll let you know the moment it launches.
