Baxi boiler cover and repair costs

First: is your Baxi still in warranty?

Every cost below turns on that one question, so settle it before you read a single price. Baxi publishes warranty lengths of up to 10 years depending on the range, and only where the boiler was registered in time and is serviced every year. Our Baxi boiler warranty guide, linked at the foot of this page, covers checking what is left in the My Baxi portal, registering, what keeps a warranty valid, and how to book an in-warranty repair with Baxi.

If the boiler is still in warranty, stop there: Baxi books and covers the repair itself, and none of the prices below apply to you. The rest of this page is for owners whose warranty has run out.

The short version

• In warranty, Baxi does the repair itself. Our Baxi boiler warranty guide covers checking, registering and booking.
• Out of warranty, Baxi publishes a one-off repair on its repairs page as a "one off payment" covering "Engineer call-out, parts, labour and VAT". It is a "from" price, so read the current figure there.
• If the boiler cannot be repaired, Baxi says it will "only charge a £90 inspection fee and refund the rest".
• Baxi's maintenance and support plans are run with Domestic & General and priced on Baxi's own maintenance and support plans page. What you pay turns on whether the boiler is in warranty, whether an annual service is included and whether the central heating system is covered as well as the boiler.
• An independent cover plan is a different product again: modular, capped at a stated limit, and not tied to the boiler brand.

Out of warranty: what a one-off Baxi repair involves

Once the warranty has run out Baxi will still send an engineer, it just charges for it, and it publishes the price on its repairs page rather than quoting per job: a "Single, fixed price repair on your boiler, carried out by one of our expert Baxi engineers", sold as a "one off payment" that includes "Engineer call-out, parts, labour and VAT". It is a "from" figure, which means the price Baxi advertises is the floor rather than the ceiling, and Baxi can change it, so take the current number off Baxi's own repairs page before you budget.

The small print matters more than the headline. If the boiler turns out not to be fixable, Baxi says it will "only charge a £90 inspection fee and refund the rest". On work that is done, "Parts are guaranteed for 12 months" and "labour is covered for 90 days".

Read what the boiler is showing before you book anything. Baxi's own booking form asks "Is the pressure gauge in the red?" and whether outside temperatures are below freezing, and answering yes to either sends you to a guidance article rather than an engineer, because a pressure reading outside the normal band, and a frozen condensate pipe in cold weather, often are not a boiler fault in themselves. Our Baxi fault code guide, linked at the foot of this page, will place a code for you first.

Whoever you use, the engineer has to be qualified for gas. The Health and Safety Executive is explicit: "Anyone employed to work on gas appliances in domestic premises must be a Gas Safe registered engineer and competent in that area of gas work." Check the card against the Gas Safe Register before work starts. HSE also "strongly advises that all gas appliances, flues and pipework should be installed, regularly maintained and serviced at least annually", and Baxi's servicing page recommends the boiler "is serviced at least annually to ensure it is in optimum condition and to keep your warranty valid".

If you ever smell gas, do not touch electrical switches, do not smoke, put out naked flames, open the doors and windows and call the National Gas Emergency Service on 0800 111 999 straight away.

The table below sets out what Baxi itself publishes, and deliberately does not pin Baxi's prices to this page. Baxi changes them, and a stale figure repeated here would mislead you. The one-off repair and Repair & Care terms come from Baxi's repairs page, and the Heating Care, Gold and Platinum terms from Baxi's maintenance and support plans page. Both are linked at the foot of this page and both carry the live price. What moves those prices is the same short list every time: whether the boiler is in warranty or out of it, whether an annual service is included, whether the central heating system is covered as well as the boiler, the plan length, and any fee charged when a repair cannot be done.

Baxi's own published options, side by side

So which route makes sense?

If the boiler is young, registered and serviced, do nothing except keep the service going. Losing a long warranty because a service was skipped is the most expensive mistake available to a Baxi owner, and it costs nothing to avoid.

If it is out of warranty and healthy, and you would rather absorb an occasional bill than a monthly one, paying per repair is defensible. Baxi's published one-off repair price is the number to hold against any monthly figure you are offered. Take it off Baxi's repairs page on the day you decide, remember it is a "from" price rather than a ceiling, and multiply any monthly plan by twelve before you compare the two.

If it is out of warranty and a four-figure surprise would hurt, a plan is the point, and the question becomes which one. Manufacturer plans are tied to the appliance brand; independent cover plans are usually modular. Our compare boiler cover guide, linked at the foot of this page, sets out what to check on any of them.

Where a Smart Plan cover plan fits

For completeness, our own product described honestly. Smart Plan is a service plan, not insurance, from UK Boiler Company Ltd, trading since 2014. It is modular, so the boiler and central heating module can be taken on its own. That module funds parts and labour up to £500 in a 12-month cover period where the boiler is under 7 years old, or up to £200 where it is over 7, and anything above the limit is yours. A £95 call-out fee, paid in advance, applies during your first 30 days, for faults the plan does not cover, no-access visits and early annual service requests, and cover itself is live from day one. Where our engineer identifies an existing defect on your equipment, we quote for that work separately rather than covering it. Using a module starts a 12-month agreement period, the 14-day cooling-off period ends the moment a service is carried out, and leaving early after that costs the remaining months or 75% of the outstanding balance. Our boiler and central heating cover page, linked at the foot of this page, has the module detail.
