Benefits of Buying a New Boiler on Finance
Getting your new boiler on finance can have it’s benefits.
Of course, depending on the finance deals available, you may end up paying more than the installation cost due to interest accruing on the loan but boiler loans offer the flexibility to move quickly and restore heating and hot water for your home.
Boiler finance works in the same way as other unsecured personal loans. The lender will assess the applicant based on credit score and a few other items and then decide how much they are willing to lend the individual and at what APR the interest will be charged at.
Once the boiler is installed, and after the finance is agreed, the lender will pay the boiler installer for the full cost of the boiler and then the applicant will repay the lender a pre-agreed monthly amount over the term of the boiler loan.
At the end of the term the boiler is fully paid for.
Firstly choose a boiler installer who offers finance packages, and if you want to get a particular boiler finance offer check your chosen installer offers what you are looking for. Your boiler installer will then be able to act as a broker and submit your application to the lender, which should be a quick and easy online process with a few verification checks.
The approval process should be fairly instant and then once approved the lender will pay your boiler installer for your new boiler on your behalf and you will pay the lender back in monthly installments until the boiler is fully paid off.
Boiler loan eligibility depends on certain factors including income levels, credit history and more. In order to be eligible for a boiler loan you must normally:

Yes, a credit check will be performed before boiler finance is offered as this typically decides the APR offered to you on the loan. But don’t worry if your credit score is not perfect, many lenders will still have boiler finance packages available to you, but they tend to be at a higher APR therefore you will end up paying more in interest over the term of the loan.

Boiler finance comes in many forms and varying different interest rates ranging from 0% up to 19.9%. The main types of boiler finance are below and we dive into each in the next sections of the article:
Typical interest rates on standard pay monthly boiler finance are between 9.9% and 12.9% APR, with the rate being offered depending on your credit score. Most lenders offer 12, 24, 36, 48, 60 and 120 month loans (1, 2, 3, 4, 5, and 10 years).
Pay monthly boiler finance is just that, it’s a boiler loan which you pay back in monthly installments until it is paid off, typically over 12 to 120 months. You will be able to decide how much deposit you pay, which is usually between £0 and up to 50% of the cost of the new boiler installation. The balance of the cost which is not covered by the deposit will be the loan amount. The monthly payment for the loan will be calculated as per the representative example below.
The bigger deposit you can afford to put down the smaller the loan and crucially the smaller the amount of interest repayable. Also the shorter the term the bigger the monthly payment but the amount of interest you will pay hugely reduces.On a 12.9% APR boiler loan with £1,250 deposit for a £2,500 boiler installation the difference in interest between a 3 year loan and a 10 year loan is nearly £700!

They can be a really good deal as you can split the cost of your new boiler into manageable monthly payments and not pay any interest.

Buy Now Pay Later boiler finance gives you a payment holiday for the first 6 or 12 months of the loan and usually require no deposit at the time of installation. If you pay back the total amount due after the payment holiday there is usually no interest added to the payment (some times there is an admin fee which has to be paid so read the small print).
Should you choose to pay back via the monthly payments then you will enter into the boiler loan ususally over 1 to 4 years after the payment holiday. It's important to note that interest on these loans usually starts accruing from the start of the payment holiday so if you have a 12 month payment holiday and a 48 month loan at the end of it you will pay back interest for the full 60 months.
In the representative example below there is a 12 month payment holiday and then a 48 month boiler loan at 11.9% APR. The £957 in interest payable includes iinterest that has accrued over the 12 month payment holiday.

No deposit boiler loans are standard boiler finance but with no requirement to pay a deposit at the time of installation, therefore the whole cost of the new boiler is on finance. These loans are typically offered across 36, 48, 60 and 120 months (3, 4, 5, and 10 years) and APR between 9.9% and 16.9%.
Not having to pay a deposit can be very beneficial, especially if the requirement for a new boiler is an unexpected purchase due to a boiler breakdown. Folding everything into a manageable monthly payment can give certainty and monthly affordability but as interest is charged on the total purchase then toe total amount payable can end up being considerably higher than the cash price of the new boiler. For example a new boiler that costs £2,500 to install on a no deposit boiler finance plan at 12.9% APR over 10 years will end up costing £4,338 of which £1,838 is interest charges.

A boiler loan can be a useful tool to make your new boiler more affordable. As with all finance agreements make sure you do your research on the type of boiler loan that you think is best for your circumstances and then find the right boiler installer who offers you a new boiler at a competitive price and also has the best version of the boiler loan you have chosen.
A boiler loan or boiler finance is a personal unsercured loan taken out to cover all or part of the cost of a new boiler installation.
A new boiler is typically financed through savings, disposable income, a credit card or a boiler finance agreement.
All boilers should be available on boiler finance as long as your installer offers brokerage services for boiler loans. The different types of boiler loans may not be available on all boilers as some (e.g. 0% APR) cost the boiler installer money to offer to customers.
Not all boiler installers offer boiler finance, but all the major brands do, as do many local installers. If you wish to explore boiler finance make sure you only engage with boiler installers who offer the product.
APR stands for Annual Percentage Rate which is how much it costs on a yearly basis to borrow money. Displayed in a standard way It's a legal requirement to be disclosed before any agreement is signed.
There are many circumstances when getting a boiler on finance makes a lot of sense. If you can secure a 0% APR boiler loan then it makes sense as the finance costs you nothing. Also if the boiler purchase is a suprise and you don't have access to the disposable income to pay it all upfront then the finace deal can make the monthly payments affordable.
No, there is no impact to a boiler warranty from a boiler finance agreement. The boiler warranty is unaffected by which ever payment method you decide to use to purchase your new boiler.
