When it comes to ensuring the longevity and efficiency of your boiler, regular servicing is key. For those with a Baxi boiler installed in their home, understanding the costs involved in servicing can help you plan and maintain your home's heating system effectively. In this guide, we'll explore the ins and outs of Baxi boiler servicing costs, ensuring you're well-informed on why it's an essential aspect of home maintenance.

Understanding the Importance of Boiler Servicing

Firstly, whether your Baxi boiler is a recent installation or has been reliably heating your home for years, annual servicing is crucial. Regular checks provide peace of mind, confirming your boiler is safe and not consuming more fuel than necessary, which could lead to inflated energy bills. Moreover, if your boiler is still under warranty, servicing ensures this warranty remains valid, keeping you covered for another year.

Baxi, a distinguished British brand, has evolved from its famous back boilers of the '60s to '80s to today's modern, high-efficiency models. Despite the changes in heating technology, Baxi's commitment to quality and reliability has remained constant. With parts readily available in the UK, Baxi boilers are a popular choice among both homeowners and engineers.

Cost Factors of Servicing a Baxi Boiler

The cost of servicing a Baxi boiler typically revolves around £100 including VAT. This price can vary depending on the service provider, with some national companies charging up to £120. It's important to note that if your boiler has a known fault, informing the engineer beforehand is wise, as repairs can increase the cost in terms of both time and money.

For the best results, consider booking your service with a Baxi-accredited installer. These engineers have undergone rigorous training specific to Baxi boilers, equipping them with in-depth knowledge and expertise that can significantly benefit the servicing process.

From an Engineer's Perspective

As seasoned engineers who have fitted and serviced Baxi boilers across London, we have encountered a range of models from the durable Baxi Solo to the newer, guarantee-covered boilers. The brand's resilience and the straightforward nature of servicing these units make them a pleasure to work with.

If you're unsure of your boiler's age, a quick internet search with the make and model number or a look through any available paperwork can give you a clear idea. Remember, while Baxi boilers are known for their reliability, they, like all appliances, have a finite lifespan—typically 14 to 16 years.

When to Consider a Replacement

While it's tempting to repair an older boiler, there comes a point when investing in a new A-rated boiler becomes more cost-effective. Not only could this save you money on your energy bills, but it also ensures your home's heating system is up-to-date and efficient.

Safety, governed by the Gas Safe Register, is always the priority. If an engineer recommends a repair, it's with your best interest in mind, aimed at ensuring your boiler is safe and efficient.


Servicing your Baxi boiler is a crucial aspect of maintaining your home's heating efficiency and safety. With costs of a Baxi Boiler Service averaging around £100, including VAT, it's a wise investment that keeps your boiler running smoothly and your energy bills in check. Remember, choosing an accredited Baxi installer for the service can make all the difference, offering you the expertise and peace of mind you deserve.


It's important to keep your boiler happy, healthy and safe for you and your family. So why not get it serviced by a Gas Safe Registered engineer annually? We  can help you with that!
