Baxi Boiler Prices, Reviews & Compare


With roots going back to 1866 and a UK network of over 200 skilled engineers, Baxi has always been focused on innovation, technology and excellence. All Baxi boilers are designed to run on natural gas but LPG conversion is available on certain models.

When comparing boilers there are a few important things to look out for, including output rating, efficiency, warranty length and potential price.

  • Output rating: Measured in kilowatts (kW), the output rating will give you an idea of how much power the boiler is capable of putting out. This is one of the most important things to check when comparing boilers as a certain output rating will be more suitable to the heating and hot water demands of your home.
  •  

  • Efficiency: Shows how much of the fuel used by the boiler is converted into energy used to heat the central heating system and domestic hot water. Many modern Baxi boilers have an ErP efficiency rating of 93%. This means that for every £1 spent heating your home, only 7p is lost to the waste gases produced as a gas boiler operates.
  •  

  • Warranty: It’s good to know that you’re covered after the installation of a new boiler and that’s where the warranty comes in. Many Baxi boilers now come with a warranty of between 7 and 10 years, which is an extensive period of time.
  •  

  • Price: A Baxi boiler will potentially cost between £600 and £1,000 which is a very reasonable price for a boiler with the efficiency and reliability of a Baxi.

See how Baxi boilers compare to your existing boiler using our Boiler Comparison Tool. You can compare the key information of up to 4 different boilers by hitting the ‘add boiler’ symbol.

Compare Baxi combi boilers

Combi boilers are compact cost-effective units that heat domestic hot water water on demand before being delivered directly to the hot water outlet, as opposed to storing it in a hot water cylinder. Baxi combi boilers are highly efficient and are covered by warranties of 3-10 years.

Compare the price of Baxi system boilers

In terms of how they operate, system boilers sit somewhere in between combi and regular boilers. They heat water directly from the mains but store it in a hot water cylinder. This means that they don’t take up as much space as regular boilers and can meet higher hot water demands than a combi.

Benefits of Baxi combi boilers

Baxi Duo-tec Combi 28 HE LPG Gas BoilerYou’ll be spoilt for choice with the Baxi range of combi boilers.

Whether you want a perfect fit in terms of output and capacity, excellent design, optimum energy efficiency – or even all of these, then Baxi have just the right choice to tick all your boxes.

A combi boiler is the most compact, space saving hot water and central heating system available today, which is why it’s also the most popular choice for modern homes.

All the clever stuff is included inside, so you don’t need to find space for a cold water expansion tank in the roof or a hot water storage cylinder in the airing cupboard or anywhere else in your home. So that’s good news!

Benefits of a Baxi Combi boiler

  • Excellent energy efficiency
  • Long-term warranties available up to 10 years
  • Compact space-saver maximises room in your home
  • Easy to use with digital display and simple controls
  • Extensive range of products choose from

When making a decision about a new combi boiler, don’t just go for the cheapest option. You need to make sure that the product you choose will work effectively to meet your specific needs so you should consider things like how much hot water you use, how well insulated your home is, and how much maintenance your system might need during its working lifetime.

Baxi Boilers – Regular Range

Baxi Solo 15 HE A Regular Gas BoilerMost of us will be familiar with a regular hot water and heating system, perhaps from parents or even grandparents’ houses, as a lot of older properties will have relied on them (and many still do!).

You can recognise a regular boiler because it’s always connected to a separate cold water tank as well as a hot water cylinder.

The latter is usually in an airing cupboard and makes a nice warm space for linen and towels.

If you want to take advantage of the benefits of a regular boiler, the modern equivalents are much more energy efficient than their predecessors and look rather sleeker too.

They still have the three crucial elements i.e. a feeder tank and a hot water cylinder as well as the actual boiler, but they also now benefit from modern design and engineering too.

Baxi’s regular range offers a choice of options.

Benefits of a Baxi Regular boiler

  • A newer like-for-like replacement gives greater energy efficiency than older models
  • A popular choice in older properties where the pipework is already in place
  • Good if you want to store plenty of hot water – perhaps if you have more than one bathroom
  • Ideal if the mains water pressure is low

The three things to think about when it comes to cost are: the purchase price of the new boiler system; installation by a qualified engineer to get everything connected and running perfectly; and the overall running cost i.e. energy bills and repairs and maintenance.

The first one is easy and you can find details for Baxi boilers and all prices on this site. Installation fees vary from one engineer to another so it pays to get three quotes / prices for comparison purposes. It’s also good to check with your provider regarding whole life costs as this can impact the type of boiler you buy at the outset. Get quotes for a new Baxi boiler.

Baxi Boilers – System Range

Baxi EcoBlue System 12 Gas BoilerA system boiler ensures a supply of hot water is pumped efficiently to radiators around the home and to a hot water cylinder to supply baths, showers and hot taps.

This type of system doesn’t have an extra cold water tank or ‘expansion’ tank as this part is built into the boiler itself rather than set up separately.

That’s good news when it comes to both installation as well as servicing as it simplifies the process for the engineer and ultimately should cost you less in time and therefore money.

Baxi system boilers are particularly energy efficient so if you want a greener choice, this could be the one for you.

Benefits of a Baxi System boiler

  • Baxi system boilers offer excellent energy efficiency
  • Economical to run and kind to the environment
  • Easy and neat to install as most of the major parts are built in
  • Provides a consistent supply of hot water, even when demand is high

This will ensure the boiler can operate as efficiently as possible, keeping heating bills to a minimum, and that there are no potential safety issues to be concerned about. A boiler service is also a great way to catch and fix small repairs before they have the chance to worsen over time and cause an expensive breakdown. Find out what’s involved in an annual boiler service, why it’s so important, the benefits and how much they cost in Baxi Boiler Service.

Baxi Boiler Warranty

Every boiler manufacturer offers a standard warranty with their boilers which last between 1-10 years. The warranty is your insurance policy and means if a fault develops the manufacturer will resolve it within a specified time frame. Some warranties include both parts and labour while others may only cover parts. The most important thing to remember is to get your boiler serviced by a Gas Safe registered engineer every year as failing to do so is likely to invalidate your warranty. For more detail about this brand’s warranty (including the small print) take a look at Baxi Boiler Warranty.

Baxi Boiler Repair Advice

Even the highest quality boiler can develop faults and problems as they age. Some are minor issues you may be able to handle yourself but most will need a Gas Safe registered engineer to diagnose and repair the problem. To find out if there are any common problems associated with this manufacturer you can read our guide to Baxi Boiler Repairs & Common Baxi Boiler Problems.

Baxi Error Codes

Error codes may appear on your boiler’s display; it’s your boiler’s way of telling you that something is wrong. Each manufacturer uses a different coding system to help an engineer to diagnose a fault. In some cases it may be a simple issue such as low pressure which you can adjust yourself but more technical faults will certainly need a professional. We’ve put together a list of Baxi Error Codes to help you understand what’s wrong before you contact an engineer.
