Smart Plan cover terms at a glance
The terms behind every cover answer below. Smart Plan is a service plan from UK Boiler Company Ltd (company 09078640), not insurance, so it does not carry insurance-style protections.
- Cover limits per 12-month period: up to £500 on most modules, £225 per appliance, and boiler and central heating up to £500 when the boiler is under 7 years old or up to £200 when it is 7 years or older. You pay any shortfall above the limit.
- Cover-plan call-outs run Monday to Friday, 08:00 to 18:00. If your boiler fails outside those hours, the earliest we can attend is the next working day.
- A £95 call-out fee, paid in advance, applies in defined cases: any call-out in the first 30 days of a new agreement, issues that fall under an exclusion, visits where our engineer cannot get access, and early annual-service requests. The first 30 days is a fee window, not a gap in cover.
- An annual service is not automatically included in cover, so arrange one separately unless your product includes it.
- One-off works run 09:00 to 17:00 and do not carry a workmanship guarantee, so they are not the same as cover.
- Billing is monthly, but a 12-month agreement period begins once you use a service. A 14-day cooling-off period applies from sign-up and ends if a service is carried out inside it.
- Leaving during the agreement period costs the remaining monthly payments, or 75% of the outstanding balance as a one-off.
- Exclusions apply and are set out in our terms and conditions.
Baxi boiler FAQs
Which Baxi boiler is right for my home?
It depends on your hot water demand and whether you already have a cylinder. A combi such as the Baxi 630 or 830 takes water straight from the mains and suits smaller homes with one bathroom. A heat only boiler works with a cylinder and feed tanks, which suits larger homes running several taps at once. The model reviews above cover each range in turn.
What do the numbers in Baxi model names mean?
The leading digit is the range and the last two digits are a kilowatt rating, but which rating depends on the boiler type. On the combis it is the maximum hot water output, so a Baxi 836 delivers a higher flow rate than an 830. On the system and heat-only models it is the central heating output instead, which is why a 630 Combi and a 630 Heat are rated for different things. Check the figure for your exact model.
What is the difference between the Baxi 600 and 800 ranges?
The 800 is Baxi's higher specification range and the 600 sits below it. Both are condensing gas boilers sold in combi form, and both use the same numbering for output. Guarantee terms differ between the ranges and can depend on who fits and registers the boiler, so check Baxi's current terms for the exact model before you buy.
Who makes Baxi boilers?
Baxi boilers are made by Baxi Heating UK, which is part of the BDR Thermea Group. Baxi has manufactured in the UK for many decades, and the same group is behind the Potterton, Main and Megaflo names. For owners this mainly matters at repair time, because parts for current Baxi ranges are widely available from UK merchants, while parts for discontinued ranges can be harder to find.
Are Baxi boilers reliable?
Reliability depends more on the quality of the installation, the state of the system water and yearly servicing than on the badge on the front. Baxi is a long established British brand fitted in homes across the UK. Common faults on condensing combis include pressure loss, ignition problems and poor circulation. Most are repairable, though on an older boiler the cost of a major part can exceed the plan limit.
Can I get cover for an older Baxi boiler?
Yes. The limit follows the boiler's age, not the range name. Under 7 years old the boiler module contributes up to £500 towards parts and labour in a 12-month period; at 7 years or older, up to £200, and you pay anything above that. The boiler must be working when the plan starts, because an existing fault counts as pre-existing. Full cover terms are set out on this page.
