Which are the Best Cheap Boilers?

Best cheap boilers

If it’s time to replace your heating system then finding the best cheap boilers may be a high priority. Many leading boiler manufacturers offer more affordable options well worth considering.

Here we look at the best cheap combi boilers as they’re commonly less costly than system and regular boilers.

What is the cheapest price for a combi boiler?

Combi boiler prices start at around £450 rising to over £2,000. They’re often the cheapest type of boiler and don’t need to be installed alongside any tanks or cylinders which will help to keep installation costs down too.

 
It isn’t unheard of for combi boilers to cost more than £2,000 but most come below this figure.

As well as the cost of the combi boiler itself, you’ll also need to think about the installation. This will add to the costs and tends to be priced between £500 and £1,000.

Combi boiler installation prices are likely to be at the higher end of this scale if it’s replacing a different type of heating system (system or regular boiler). Or, if you’re planning to move the boiler from one location to another.

To keep installation costs to a minimum, we highly recommend comparing quotes. Getting quotes from at least 2 heating engineers will give you the confidence you’re receiving a competitive price.

How to save money on boiler installation

So, you’ve done your research and found the best cheap boiler for your home. Next, you’ll need to find a heating engineer to carry out the installation. And we have a few tips to help you save money on a boiler installation.

On average, the installation of a combi boiler can cost between £500 and £1,000. It’s possible for the price to go beyond £1,000 if it’s a particularly complex installation.

“The single best thing you can do to save money on a boiler installation is to compare quotes.”

 
By comparing quotes from at least 2 heating engineers, you can be confident that you’re getting a fair price. If you were to receive a single quote you wouldn’t know if you were being overcharged.

As well as comparing quotes, you can save more money by arranging the installation for during the summer. Heating engineers tend to have more time available in their diary when the weather’s warmer which can reduce the costs.

Plus, replacing your boiler when you’re less likely to need the heating will reduce disruption and you’ll have a new efficient heating system once winter comes around.

Spread the cost with boiler finance

Rather than paying for a new boiler installation all in one go, you may be able to spread the cost. With boiler finance, you could potentially be making monthly payments of as little as £15 to £20. With interest you may end up paying more than if you paid in full upfront but it’s a more manageable option for many people.
