Frequently asked questions
Here are the answers to some of the most common questions we are asked. If you can't find the answer to your question, contact us and we will be please to help you .
How often should I get my boiler serviced?
Your boiler should be serviced annually (this is a legal safety requirement if you live in a rented property). The best time to do this is during the summer months when installers are not so busy. Any Gas Safe registered installer should be able to carry a service for you.
The benefits of an annual service include:
- Peace of mind - your installer should inspect and test all key components in your appliance during the service
- Your boiler will work at maximum efficiency - an annual service can reduce gas consumption, save you money and minimise the risk of future breakdowns
- An annual service is required to ensure your warranty is valid

Are Baxi engineers Gas Safe registered?
All Baxi Customer Support engineers are Gas Safe registered and experts in Baxi appliances.
Do you use third-party contractors?
Yes, Baxi does sometimes use third-party subcontractors to carry out work on your behalf. This usually happens when we are busiest to assist us with annual servicing. The only other time we'll use subcontractors is in more remote areas of the country, for instance in remote parts of Scotland and/or the Isle of Wight where we do not have Baxi Customer Support engineers.
The companies that we use are carefully selected and trusted by Baxi, and fully trained on our products. We have very good relationships with these companies and they are aware of the high standard of work that we expect.
What type of boiler do I need?
The type of boiler you need will depend on the size of your house, plus your hot water requirements. We can help you choose the most appropriate Baxi gas boiler for your home with our Product Selector
What do the letter ratings on your boiler stand for?
As part of the Energy-related Products (ErP) initiative, all gas boilers must show their energy efficiency rating.
The letters are rated from G to A, with a G-rated boiler being the least efficient (less that 70%) and an A-rating being the highest efficiency.
All Baxi boilers are A-rated which means they operate at over 90% efficiency.
The hot water supply from my combination boiler fluctuates. Is this correct?
Depending on heat output, combination boilers can only supply a one tap at a time. Turning on additional taps will reduce the flow of hot water. If the water is not hot enough you may have to reduce the flow (by turning the tap down) to increase the temperature. This may be necessary especially in winter when the water supply to the boiler is colder.
