If you are having a Baxi boiler fitted, a Baxi Approved Installer is an engineer Baxi has trained on its own boilers, who knows exactly what the warranty needs at handover. The length of the warranty itself comes from the Baxi range you choose, not from the installer. What the right installer does is make sure the conditions are met, so you actually keep that warranty.
This post explains what the approval means, how long Baxi warranties last, what keeps them valid and what to check before you book. One safety point first: any work on a gas boiler must be done by a Gas Safe registered engineer by law, so never fit, move or open up a gas boiler yourself.
What a Baxi Approved Installer is
Baxi Approved is a status Baxi gives to heating installers who are trained on its products and fit them to its standards. Approved installers also have direct access to Baxi's technical support, which helps when a tricky fault or an unusual system needs a second opinion.
It sits on top of the legal minimum, not in place of it. Every engineer who works on a gas boiler must be on the Gas Safe Register, the official list of businesses qualified to work safely on gas appliances. Our guide on how to check if a gas engineer is Gas Safe registered shows you how to look anyone up in a couple of minutes.
How long a Baxi boiler warranty lasts
Baxi sets the warranty by range. According to Baxi, the parts and labour warranties are:
- Baxi 800: 10 years
- Baxi 600: seven years
- Baxi 400: five years
- Baxi 200: two years
These lengths depend on the boiler range and on meeting Baxi's conditions. Baxi's own warranty pages don't make them depend on who fitted the boiler, and they say there is currently no option to extend the manufacturer's warranty beyond them. So be wary of any promise of a longer Baxi warranty that you can't see written down in Baxi's terms.
What keeps your Baxi warranty valid
The full warranty only holds if a few things happen. Baxi's conditions are:
- The warranty is registered within 30 days of installation. Your installer may do this for you, but check.
- The Benchmark checklist is completed. This is the commissioning record in the back of the boiler manual, where the engineer notes the settings, gas readings and system checks at installation and at each service.
- The boiler is serviced every year by a Gas Safe registered engineer, with proof of each service kept.
- On a Baxi 800, the magnetic filter is fitted and looked after. This is a small unit on the heating pipework that catches the black iron sludge that builds up in radiators and pipes.
Miss one and the warranty can drop back to a much shorter standard period. Baxi also doesn't cover failures caused by outside problems, such as incorrect installation or sludge in the system.
Where an approved installer makes the difference
Most of those conditions are in the installer's hands on the day. A good installation of a Baxi boiler means:
- the old system is cleaned before the new boiler goes on, so sludge doesn't damage it from the start
- inhibitor is added to the water, a liquid that slows the corrosion that causes sludge (our post on what central heating inhibitor does explains more)
- the filter is fitted where it can be reached and cleaned at each service
- the Benchmark checklist is filled in properly and left with you
- the warranty is registered in time, or you're told clearly that you need to do it
An engineer trained on Baxi boilers knows these steps for each model and has Baxi's support team to call if something doesn't add up. That's the real value of the approval: fewer gaps that could cost you your warranty later.
How we fit a Baxi boiler
AB Plumbing and Maintenance are Baxi Approved Installers and Gas Safe registered, and we're also Alpha Approved Installers. We start by looking at your home and how you use your heating and hot water, then recommend a Baxi boiler that suits it and give you a written quote.
You can read more about how we plan and fit a new boiler on our boiler replacement service page.
Questions to ask before you book any installer
Whoever you choose, a few questions will tell you a lot:
- Are you Gas Safe registered, and can I see your ID card?
- Which Baxi range are you quoting for, and how long is its warranty?
- Who will register the warranty, and when?
- Will the system be cleaned and a filter fitted?
- Will I get the Benchmark checklist and a Building Regulations Compliance Certificate?
That last certificate shows the installation was notified to your local council, which your engineer must do for a new boiler in England and Wales. Keep it with your house paperwork, as you'll be asked for it if you sell.
Keeping your warranty after it's fitted
Once the boiler is in, the main job is yours: book a service every year and keep the paperwork. The engineer should check the system water is clean, clean the filter and record the visit in the Benchmark section. If you move house, a registered warranty stays with the boiler, so the new owner just needs to keep up the annual service.
Our boiler servicing visits cover all of this, whoever fitted your Baxi boiler.
