Boiler Installation & Replacement in High Wycombe
A new or replacement boiler from a Worcester Bosch Gold Accredited Installer — gas, oil and LPG, fitted correctly the first time by Gas Safe and OFTEC registered engineers, with manufacturer warranties up to 10 years.
The right boiler, fitted right, backed by the best warranty
Whether your old boiler has finally given up or you simply want a quieter, cheaper-to-run home, we install new and replacement boilers across High Wycombe and the surrounding areas.
Smith's Heating Services has been a Worcester Bosch Gold Accredited Installer since 2003 — the manufacturer's highest installer status. That accreditation lets us register longer warranties and gives you the reassurance that your boiler has been fitted to the standard the manufacturer demands. We install on gas, oil and LPG, so whether you're on the mains or off-grid, we have you covered.
We believe correct installation is the single most important thing. A boiler is only ever as good as the system around it, so we take the time to survey your home, size the boiler properly and commission it correctly. It's why over 90% of our work comes from referrals — and why the job is not finished until the paperwork is done.
Three reasons High Wycombe trusts Smith's
Gold Accredited expertise
A Worcester Bosch Gold Accredited Installer since 2003, registered with Gas Safe and OFTEC. The accreditation that lets us offer the longest warranties — earned by installing correctly, every time.
Done properly, paperwork and all

Local, family-run, referral-led
A family-run team based on Derehams Lane in High Wycombe. Over 90% of our work comes from referrals, so we look after every customer as if our next job depends on it — because it does.
Why upgrade your boiler?
If your boiler is more than a decade old, a new high-efficiency model usually pays for itself in comfort, reliability and running costs.
Lower running costs. Modern condensing boilers are far more efficient than older units, turning more of the fuel you pay for into heat for your home. For most households that means noticeably lower bills and a warmer house, sooner.
Reliability when you need it. An ageing boiler tends to fail at the worst possible time — in the depths of winter. A new boiler, installed and commissioned correctly, gives you dependable heating and hot water and far fewer breakdown call-outs.
The best warranty, protected. As a Worcester Bosch Gold Accredited Installer we can register manufacturer warranties of up to 10 years on qualifying gas boilers and up to 7 years on oil boilers. That cover depends on the boiler being installed correctly and serviced annually — both things we take care of for you.
Quieter, smarter comfort. New boilers run more quietly and pair with smart controls such as Nest, Bosch EasyControl and Drayton Wiser, so you can heat the right rooms at the right times from your phone.
Finance available
A new boiler is a significant investment — and it doesn't all have to come at once.
We offer finance options to help you spread the cost of your new boiler over manageable monthly payments, subject to status and affordability. Talk to us about what's right for your budget when we quote.

Which boiler is right for my home?
It depends on your property size, the number of bathrooms, your hot-water demand and whether you run on gas, oil or LPG. As a Worcester Bosch Gold Accredited Installer we survey your home and recommend the correctly sized combi, system or regular boiler — never an off-the-shelf guess. The right size and type keeps running costs down and protects your warranty.
How long does a boiler installation take?
A straightforward swap of a like-for-like boiler is usually completed in a single day. Moving the boiler position, changing fuel or boiler type, or upgrading the system can take two to three days. We confirm a clear timescale in your quote after the survey so there are no surprises.
How long is the warranty on a new boiler?
Because we are a Worcester Bosch Gold Accredited Installer we can register manufacturer warranties of up to 10 years on qualifying gas boilers and up to 7 years on oil boilers. Correct installation and an annual service are what keep that warranty valid — and the job is not finished until the paperwork is done.
Do you remove the old boiler?
Yes. We disconnect, decommission and remove your old boiler and any redundant pipework, and we dispose of it responsibly. We leave your home clean and tidy, and hand over all the commissioning and warranty paperwork before we go.
