  • Interest-free, low-interest, Buy Now, Pay Later deals, as well as government grants, are the most common ways to finance a boiler in the UK.
  • Financing a boiler makes a new boiler accessible without a big initial investment and helps you reduce your energy bills without having to save the full amount of the boiler's price.

As of May 2025, the average annual energy bill for UK households has increased by 77.45%, soaring from £1,042 to £1,849. This alarming jump puts a crippling burden on heating expenses, especially for households with old, inefficient boilers. This is when exploring boiler finance options becomes a necessary lifeline rather than a convenience.

This guide will walk you through the boiler payment plans and eligibility criteria in the UK, as well as the boiler finance companies you can choose from.

Boilers on finance explained

boiler on finance process

Boiler finance schemes allow homeowners to spread the cost of a new boiler by making monthly payments for a predetermined period, usually ranging from 12 months to 10 years. 

Similar to any other loan agreement, you must take the following steps to enrol:

  1. Application: Select a preferred boiler and financing option, and complete an application form with your personal and financial details. 
  2. Loan eligibility checks: The finance provider will verify your identity and address, assess your credit history, and evaluate your affordability based on your income and outgoings.
  3. Loan approval: If successful, your application will be approved, and you will need to review and sign a credit agreement on the loan amount, interest rate (APR), total repayable amount, monthly payments and their schedule, as well as any early repayment options and conditions.
  4. Start of payments: According to the payment schedule, your monthly payments will begin, typically through direct debit. The typical payment range is £49–£167 based on the boiler cost and term length.
Can you get a boiler on finance with a bad credit score?

Whether your credit score is bad or good is determined by various credit reference agencies based on their scoring models and ranges. On average, a credit score is considered bad if it scores below 640 points. Getting your boiler financed with such a score is way more difficult, though not impossible.

 

Applicants with a poor credit score usually face higher interest rates (11.9% – 39.3% as opposed to 9.9% – 12.9% for a good score), fewer financing opportunities, and stricter affordability checks like debt-to-income ratios or proof of employment for at least 6 months. If your credit score is considered bad, you can access boiler financing options through specialist lenders, subscription models or government schemes like ECO4 or the BUS (Boiler Upgrade Scheme).

Most boiler finance companies typically provide installation alongside financing. Upon the application and approval, the property is assessed by an in-house Gas Safe registered engineer for heating system compatibility and safety. The actual boiler installation takes place 24-72 hours after the loan approval, followed by warranty activation. 

While self-sourced installers aren't typically recommended, they are allowed by some smaller finance providers. You should contact your boiler finance company to find out about any installer accreditation requirements and the necessary documents (invoices, compliance certificates) you need to provide.

Boiler finance options

There are two main categories of boiler finance in the UK: commercial and government-backed. The former is backed by boiler suppliers and installers, and the latter is designed to promote energy efficiency and fight fuel poverty.

Boiler finance options
Commercial boiler finance options
Interest-free credit (0% APR)Typically available for 12-48 months based on the provider
Interest-bearing loansEnable lower monthly payments for longer repayment periods with APRs between 9.9%-12.9% up to 10 years
No-deposit optionsThe installation proceeds without any upfront payment; monthly payments are based on the term and amount
Buy Now, Pay LaterNo mandatory payments for 6-12 months; the full payment occurs at the end of the interest-free period, or beginning of monthly payments
Government grant schemes
Boiler Upgrade Scheme (BUS)Covers up to £5,000 for replacing fossil fuel systems with biomass boilers in England and Wales
ECO4 SchemeMeans-tested grant for low-income, vulnerable households to get energy efficiency upgrades, including boiler replacements. Amount varies by applicant
Nest Scheme (Wales)Home energy efficiency improvements. Eligibility is based on income and property status
Warmer Homes ScotlandCentral heating improvements. Covers up to £10,000 for a new gas boiler or a heat pump

Affordable Warmth SchemeCovers between £7,500 and £10,000 for boilers, insulation, and heating controls for households with an annual income of under £23,000
Northern Ireland Sustainable Energy Programme (NISEP)Households with an annual income of under £38,000; includes energy efficiency measures (boiler upgrades, air source heat pumps, insulation, etc.)

Costs of financing a boiler

The monthly payment for boilers on finance typically ranges between £75 and £150. The actual payment depends on whether there's a deposit payment or interest in your plan, as well as what kind of boiler you choose and how long you're going to pay.

For example, having a £2,250 boiler financed over 2 years at 0% APR would cost you £93.75 each month. Alternatively, with a 5-year plan and the interest rate of 11.9% APR, the same boiler will cost you £41.96 monthly with a total repayment of £2,517.75.

Here's a table with approximate monthly payments with and without deposits.

Advantages and disadvantages of boilers on finance

Advantages
  • Manageable payment structure: New boiler finance allows homeowners to avoid the financial shock associated with the new boiler cost and installation. On average, a £3,000 boiler can be paid over a 3-year period at £83.33 per month with 0% APR. And with longer-term plans (e.g., 10 years), you will pay around £28 for a £2,200 loan, even with 9.9% APR.
  • Access to better models: According to the current requirements, modern boilers must meet the 92% ErP efficiency requirements, so opting for boilers on finance allows for immediate access to the most efficient boilers
  • Immediate installation: In case of emergency (e.g. your old boiler can't be fixed and you can't afford a new one straight away), pay monthly boiler replacement options eliminate the need to save for a new boiler and often offer quick, next-day installations. 
  • Warranty and servicing packages: Most boiler payment plans include 10-year coverage for repairs, replacements, and annual maintenance. 
  • Energy bills savings: Modern boilers are designed to reduce energy consumption by up to 30% compared to older systems. By taking advantage of the newer boilers' features, a UK household with an average heating bill of £1,720 can potentially save up to £516 every year.
Disadvantages
  • Potentially higher overall cost: While opting for  0% boiler finance, you're safe from overpaying, but interest-bearing plans can increase the total commitment. For example, a 7.3% APR adds 41.2% to the total cost, making a £3,000 boiler cost £4,236 over 10 years.
  • Long-term financial commitment: Most pay monthly boiler plans stretch between 2-10 years, often penalising homeowners seeking to settle their debt ahead of schedule.
  • Credit check requirements: Most plans exclude borrowers with poor credit scores from 0% APR deals, only offering options with high (starting from 11.9%) interest rates. This might affect a lot of low-income households, as 6.29 million UK citizens currently have low credit scores.

Which companies provide boilers on finance?

You can have your boiler financed through a heating installer, a boiler manufacturer or an energy provider. As for the latter, British Gas and E.ON are two major UK energy suppliers that provide comprehensive financing terms and transparent pricing. 

Here's an overview of the UK energy suppliers and their boiler finance terms:

These providers operate throughout the UK, yet there are some which focus on Scotland (Home Energy Scotland) or Northern Ireland (HeatNI, Belfast Gas 0% Finance) specifically. 

Therefore, for more boiler financing providers in your region, you could consult a local boiler installer. This way, you will access companies that address local market conditions and the heating needs of your particular region while providing faster response times and competitive prices.

Should you get a boiler on finance?

Amidst the current cost-of-living crisis, more and more homeowners are on the lookout for ways to buy a boiler on finance. If you're among them or not eligible for boiler grants, then you should know there are ways to upgrade your heating system with a modern and efficient boiler without breaking the bank.

By spreading the cost with flexible payment plans, you can save money in the long run and ensure your home stays warm and comfortable, even when your budget is tight.

If you're a UK resident, between 18 and 35 years of age, and have an employment contract of at least 16 hours, you are most likely eligible for boiler finance options. Yet, even the best, most efficient boilers can fail if installed incorrectly. That's why you want your boiler installation to be handled by an experienced professional. 

But how do you know the installer you found on the internet is trustworthy? You can spend countless hours reading the reviews, calling up the installers and comparing their fees without any guarantee that your boiler will be in good hands.

Alternatively, you can complete our 30-second form and get up to 3 quotes from local installers – all within 48 hours. There's no need to pay anything or accept any offers.
