Boilers on finance explained
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:
- Application: Select a preferred boiler and financing option, and complete an application form with your personal and financial details.
- 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.
- 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.
- 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.
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.
| Commercial boiler finance options | |
|---|---|
| Interest-free credit (0% APR) | Typically available for 12-48 months based on the provider |
| Interest-bearing loans | Enable lower monthly payments for longer repayment periods with APRs between 9.9%-12.9% up to 10 years |
| No-deposit options | The installation proceeds without any upfront payment; monthly payments are based on the term and amount |
| Buy Now, Pay Later | No 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 Scheme | Means-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 Scotland | Central heating improvements. Covers up to £10,000 for a new gas boiler or a heat pump |
| Home Energy Scotland Grant and Loan | Up to £7,500 grant and £7,500 loan for biomass boilers, heat pumps, and insulation. Additional £1,500 uplift for rural and island homes |
| Affordable Warmth Scheme | Covers 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.
| Pay monthly boilers (no deposit) | Pay monthly boilers (with a deposit) | |||
|---|---|---|---|---|
| Repayment period | 3 years | 10 years | 3 years | 10 years |
| Deposit | £0 | £0 | £1,045.25 | £1,070.50 |
| Total loan amount | £2,246 | £2,246 | £1,200.75 | £1,175.50 |
| Total credit charge | £447.16 | £1,691.60 | £239.25 | £864.50 |
| Total amount repayable | £2,693.16 | £3,897.0 | £2,485.25 | £3,110.50 |
| Monthly cost | £74.81 | £32.48 | £40.00 | £17.00 |

Advantages and disadvantages of boilers on finance
- 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.
- 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:
| Company | Interest-free period | APR* | Min loan | Max term | Deposit required | Warranty** |
|---|---|---|---|---|---|---|
| British Gas | Up to 3 years | 9.9% (up to 10 years) | £1,000 | 10 years | No | 5 years |
| E.ON | 2-4 years | 0% (On interest-free) | £1,000 | 4 years | No | 5 years |
| BoilerPlan | Up to 2 years | 6.9%(for non-interest options) | £1,000 (£2,200 for interest-free) | 10 years (only on non-interest options) | Varies (50% for interest-free option) | Up to 10 years |
| HomeServe | 2 years | 9.9% | N/A | 10 years (with interest) 2 years (for interest-free) | No | Up to 10 years |
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.
