When researching the cost of a new boiler, you’ll probably notice that some brands charge much less than others. But what’s the reason for this? A lot of budget boiler brands will cut a corner somewhere, meaning you’ll often get a ‘no frills’ boiler that’s inferior to those made by a more expensive brand.
If the price of a boiler is low, you should always ask yourself what it doesn’t give you. A long warranty? Exceptional build quality? Better efficiency? Superior reliability? A cheap boiler doesn’t always mean good value for money, and chances are it will probably end up costing you more in the long-term. Think breakdowns and repairs, and high heating bills. Not to mention the misery of a cold morning shower.
It’s therefore essential to find a balance between quality and cost, and there are plenty of brands that produce good boilers at a competitive (but not necessarily the cheapest) price. In this article, we’ll introduce you to the best budget boiler brands, and how much you can expect to pay for their cheapest boilers.

Battle of the Budget Boiler Brands
When you think of cheap boilers, brands like Vokera and Ferroli might come to mind. With their boilers starting from as little as £440, it’s easy to see why you could get sucked in by their prices. However, these brands have received some heavy criticism from both customers and boiler engineers for their disappointing build quality and overall reliability. With these brands, you really do get what you pay for.

Instead, we’d recommend mid-range brands such as Alpha, Baxi, Glow-worm and Potterton. While their prices aren’t quite as low as Vokera and Ferroli, their boilers are much better quality and won’t cost you an arm and a leg. These brands don’t produce the best boilers that money can buy (think Worcester Bosch and Viessmann), but they do offer great value for money if you’re on a budget. Read on to find out how much boilers cost from these mid-range brands.

Cheap Boiler Prices
Value for money boilers typically cost between £520 and £2,500. Although this might seem like a lot, boilers made by top-of-the-range brands start from around £700 and increase to over £4,000.
The amount you’ll pay will be affected by the size of your house, however. The more radiators, taps and showers your home has, the bigger the boiler you’ll need (in kW) – and the more this will cost. So if you live in a 4-bedroom house, chances are you won’t be able to get the cheapest boiler on offer.
As a rough guide, this is the combi boiler size you’ll need:
For a 1 or 2-bedroom house with 1 bathroom: 24 to 27kW
For a 3 or 4-bedroom house with 1 or 2 bathrooms: 28 to 34kW
Anything bigger: 35 to 42kW
And this is the conventional and system boiler size you’ll need:
1-bedroom flat: From 12kW
2 or 3-bedroom flat or house: 15kW to 18kW
4 or more bedrooms: 24kW to 30kW
The table below shows you the price of boilers produced by the best ‘value for money’ brands – Alpha, Baxi, Glow-worm and Potterton.
Size Range (kW)
20 to 40
£520 to £2,575
12 to 32
£650 to £1,440
12 to 35
£610 to £1,855
12 to 33
£580 to £2,740
Cheap Combi Boilers
Combi boilers – or more formally, combination boilers – are the most common type of boiler in the UK. This type of boiler heats water directly from the mains when you turn on a tap or switch on your central heating, so you won’t need a hot water cylinder or cold water tank built into your loft. This means combi boilers are compact, great if you live in a small house or flat.
The table below shows you the cheapest combi boilers made by the best value brands on the market.

Cheap Conventional Boilers
Also known as heat-only or regular boilers, conventional boilers are useful if you already have a heating and hot water system linked to a hot water cylinder. They must also have a cold water tank up in the loft which will feed the hot water cylinder, and a tank which maintains the central heating’s water level.

Cheap System Boilers
A system boiler heats water directly from the mains when you fire up your central heating, but uses a hot water cylinder to heat water for your taps or shower. This will need to be stored in your loft.

Cheap Boiler Installation
When calculating how much a new boiler will cost you, It’s easy just to focus on the price of the boiler and forget about the installation cost. However, installation can sometimes cost as much as the boiler itself, so it’s important you shop around and compare quotes from several installation companies to find the best price.
Top tip: Local companies have been found to charge up to 33% less for the same boiler installation as big energy providers like British Gas
The cheapest installer will not always be the best option, however. Quality is crucial. If you choose an installer based only on price, they may not do a particularly good job which could leave you paying the price for repairs and maintenance down the line. So always do your research; have a look for feedback from previous customers, and ensure that they’ve got the appropriate qualifications for the job. You should always use a Gas Safe registered engineer if you’re installing a gas boiler, and an OFTEC registered engineer if you’re installing an oil boiler.
What If You Can’t Afford the Upfront Costs?
If you’re on a tight budget and really can’t afford to pay for your boiler upfront, there are some alternative options that will allow you to get a boiler at an affordable price (or even subsidised), without compromising on quality.
Boilers on Finance
Buying a boiler on finance allows you to break its cost down into manageable monthly instalments, which you pay over a number of months (or years). This means you won’t need to pay for your boiler in one lump sum. Interest can be added to your monthly repayments, however, meaning you’ll pay more for your boiler than it’s actually worth.
Most companies offer a wide range of finance options, so you should be able to find one that suits your needs. Here is an example repayment plan for a new boiler:

Under the Government’s ECO scheme, some homeowners in England, Scotland and Wales are eligible to receive money towards a new replacement boiler. Funding is limited, however, so the eligibility criteria is strict. Your household income must be less than £20,000 a year and you need to be receiving at least one benefit from the Government. To find out more about the ECO scheme, visit our guide on Government subsidies for boilers.
