When it comes to the cheapest way to heat your home, gas boilers are the most cost-effective option. This is because gas is currently the cheapest fuel type in the UK.
In terms of boiler model, the cheapest choice is a combi boiler, as it requires less work in the installation process.
The best cheap boilers
To begin with, we'll point out that buying the cheapest boiler isn't always the best course of action. Anyone considering a budget boiler should, first of all, browse or ask an installer: "How long does a cheap boiler last?"
The average lifespan of cheaper boiler models in the UK is between 10-15 years. But the actual lifespan of a boiler depends on its quality, type, and maintenance.
Cheaper boilers may need more frequent repairs and replacements much sooner than more expensive or higher-quality ones. Essentially, you get what you pay for.
Having said that, there are many reliable and affordable boilers available on the market. And many are manufactured by leading boiler brands.
From a survey with over 1,400 people, Boiler Guide found the best boiler brands in the UK. All of the top brands are reputable and have very popular boiler models used by homeowners across the country. In first place with 42% of the installations is Worcester Bosch, followed by Vaillant, Ideal, Baxi, and Viessmann.
In the rest of this guide, you'll find the best cheap boilers to buy in 2024 from the best boiler brands on the market, what to look out for when buying cheap boilers, and the best strategy to buy budget boilers.

Cheap combi boiler deals
Combi boilers are often the cheapest type of boiler and tend to be popular because they're space-efficient and don't need to be installed alongside any tanks or cylinders. Combi boiler prices start at around £500 and can rise to over £2,000, excluding installation costs.
While it isn't unheard of for combi boilers to cost more than £2,000, most fall below this figure. Top boiler manufacturers can sell quality boilers at low-cost points. For example, one of the cheapest combi boilers in the UK is Baxi's 424 combi gas boiler which sells for £649, excluding installation costs.
So, how do you find deals for cheap combi boilers for sale in the UK? Proper quote comparison by yourself involves a lot of valuable hours spent calling local engineers.

Cheap system boiler deals
The cost of system boilers, on average, ranges from £700 to £2,600, excluding installation costs. System boilers tend to be popular for households that have a high hot water demand because they have an unvented cylinder that stores the hot water. For example, one of the largest system boilers has an output size of 99kW and can reach prices as high as £3,837.
However, 99kW is higher than needed for domestic boilers. For a small household with up to 10 radiators, one of the cheapest regular boilers is the Baxi Megaflo System 15 which costs £711 and has an output of 15kW.

Cheap conventional boiler deals
Generally, conventional boilers, also known as regular or heat-only boilers, range from £500 to £2,700, excluding installation costs. The price typically depends on the size of the boiler you’re installing. Some larger conventional boiler prices can go as high as £3,000.
However, typically you can find a cheap heat-only boiler from reputable brands starting at around £700. For instance, Baxi’s 412 heat-only boiler, costing £695, is the cheapest conventional boiler of the top 5 boiler manufacturers.
The total cost of getting a conventional boiler will increase when the boiler installation is considered. As conventional boilers need to be installed with a hot water cylinder and cold water cistern. This is why it's recommended to get a new conventional boiler only if you’re replacing an existing one and have enough loft space and an airing cupboard.
Ultimately, the installation cost depends on your current heating system. A boiler engineer will be able to give you more accurate quotes for your total boiler cost, including the installation and any extra parts, such as the boiler flue and hot water cylinder.

When looking for a cheap new boiler, it is good to keep in mind that there are some trade-offs and risks you take with getting the cheapest boiler. You may save on upfront costs, but you take the risk of incurring higher repair costs in the future.

This is also why gas boilers might get phased out, read more about this in our ‘are gas boilers being phased out?’ guide.
However, when getting a cheap boiler, you can minimise some of this risk if you don’t get a cheap boiler from an unreputable brand. Another way to minimise the risk of high repair costs is by not forgetting to get an annual boiler service.
