    What is boiler finance?

    Finance for your boiler installation!

    To begin with, getting a new boiler can be a big investment. Paying for it in one single large payment can leave a huge impact on your budget. However, this is something that you don’t have to worry about. Nowadays, you can pay monthly for your brand new boiler with 0% interest and no deposit needed.

    Firstly, a boiler replacement can cost a huge amount of money. It can cost you between £1,500 to £3,000. It’s perfectly understandable if you don’t have that amount on hand right now.

    But worry not! You can easily get a monthly finance plan to pay for your new boiler. This plan will enable you to spread the cost over a period of time that is suitable for your budget. Moreover, you can pay for it in 2 years, 5 years or even in a decade. The choice is yours. And here lies the beauty of boiler finance.

    We can also offer a number of split payment options for you to choose from.
