Buying a boiler on finance can be hard with all the different options available. Let us explain all this in plain English for you.
There's no need to pay the full cost of your new boiler upfront; you can spread the cost of your new boiler. Pay in affordable monthly instalments.
How consumers carry out purchases has changed a lot over the past few decades, with people buying clothes, cars, technology and houses on finance plans.

At iHeat we know and understand that a boiler not working can come at the most inconvenient of times, and not everyone can fork out the money to purchase a new boiler right away.
(All figures are intended as a guide only)
In fact, according to a recent survey by Which?, 33% of UK households can’t afford to cover the cost of a new boiler.
We believe that no matter your financial circumstances, you shouldn’t have to come home to a cold house, particularly in the winter months, so we offer a range of finance options to suit you.
According to The Energy Saving Trust, the average boiler replacement costs £2,300 but can cost anywhere between £1,500 and £3,500+, depending on the boiler and the job's complexity.
Unfortunately, the average amount of money households have set aside for repairs and replacements is just £765.
The cost is spread out by paying for a boiler on finance, making it more affordable monthly instead of paying for it all at once.
Purchasing through finance also allows you to pick from a range of boilers instead of settling for the cheapest option due to limited savings.
When purchasing a new boiler through finance, you take all the same initial steps as you would if you were paying directly. The only difference being you need to complete a finance application at the end of your order simple.

The Affordable Warmth Obligation in 2025 remains a cornerstone of the UK Government's strategy to enhance energy efficiency and support disadvantaged households as part of the Energy Company Obligation scheme.
In 2025, the objective of the Affordable Warmth Obligation is to mitigate fuel poverty by providing essential improvements to make homes more energy-efficient. This effort is a component of the broader Energy Company Obligation (ECO4), a collaborative initiative between the government and major UK energy suppliers. The scheme emphasizes providing services like the free boiler scheme and boiler upgrade scheme, aimed at replacing old, inefficient heating systems with more eco-friendly and efficient alternatives.
Eligibility for the Affordable Warmth Obligation is determined by a combination of income, benefits received, and property type. Specifically, individuals may qualify if they:
Are recipients of certain state benefits, such as Universal Credit, Pension Credit, or Income Support.
Own their home or rent privately (tenant applications require landlord permission).
Possess an inefficient, faulty, or outdated boiler.
Applicants must provide proof of benefit receipt and property ownership to confirm eligibility.
To apply for the Affordable Warmth Obligation, applicants must:
Verify they meet the eligibility criteria.
Gather necessary documents to demonstrate eligibility.
Reach out to an energy supplier participating in the ECO4 scheme.
The energy supplier will guide applicants through the application process and organise a survey if the initial review is positive. They will also detail the steps and documentation needed for a successful application. Local councils or energy-efficiency advisory services may offer additional support.
The Energy Companies Obligation for 2025 plays a vital role in improving energy efficiency and aiding vulnerable households in the UK.
The ECO scheme, now in its fourth iteration (ECO4), operates in partnership between the government and the UK's largest energy suppliers to help upgrade heating systems for those in need. Since its inception, each phase of ECO has introduced improvements and extensions, with ECO4 set to continue until 2028, focusing on sustainability and the reduction of fuel poverty.
Eligibility for the ECO scheme depends on several factors:
Homeownership or residence in social housing.
Receipt of qualifying benefits indicating low income or fuel poverty.
The property must have an Energy Performance Certificate highlighting a need for energy efficiency improvement.
The scheme targets homes with inefficient boilers, though meeting the guidelines does not guarantee acceptance into the program.
To apply for a boiler grant under ECO4, follow these steps:
Confirm Eligibility: Match your situation with the ECO scheme criteria.
Collect Required Documents: Including proof of occupancy, benefits, and your Energy Performance Certificate.
Contact an Approved Supplier: Engage with energy companies collaborating with the government.
Assessment: Suppliers will evaluate your boiler efficiency and home energy needs.
Approval and Installation: Eligible applicants will have their upgrades scheduled.
Direct communication with energy suppliers or official ECO4 support channels is advised as application processes may vary.
The LA Flex Scheme 2025, integral to the Energy Company Obligation (ECO4), underscores the shift towards low-carbon heating and enhancing household energy efficiency.
The LA Flex Scheme enables local authorities to nominate households that might not meet ECO4's national eligibility criteria for energy-saving measure installations, including boiler replacements and insulation. This scheme acknowledges the importance of heat pumps in transitioning away from fossil fuel heating.
The LA Flex Scheme extends to:
Residents in inefficient homes as identified by local authorities.
Households unable to improve energy efficiency without aid.
Eligibility is influenced by the household's current energy efficiency and income level.
To apply, follow these steps:
Contact your local authority for eligibility inquiries and express interest.
Provide required documentation as specified by the local authority.
Upon referral, an energy provider will evaluate the property to identify suitable energy-saving measures.
Approval processes and subsequent actions may differ across locations, reflecting each community's specific needs.
The Boiler Upgrade Scheme in 2025 offers grants for replacing old fossil fuel heating systems with greener alternatives like heat pumps and biomass boilers, aimed at increasing energy efficiency and reducing carbon footprints.
The scheme supports the installation of sustainable heating technologies, facilitating the shift to low-carbon heating by alleviating initial costs.
Grant Values: Grants of up to £7,500 are available for air and ground source heat pumps.
Exclusions: Hybrid systems that combine heat pumps and fossil fuel boilers are not eligible.
Installation Requirement: Only MCS-accredited installers can carry out the work to ensure quality and adherence to standards.
The scheme is open to:
Homes and non-domestic buildings in England and Wales with existing fossil fuel heating.
Installations must be completed by an MCS-accredited installer.
Confirm eligibility before installation to ensure compliance with scheme requirements.
Application Process
To apply, undertake the following:
Obtain installation quotes from MCS-accredited installers.
The installer submits the application on behalf of the applicant, registering the project with Ofgem.
Upon approval, the grant is paid directly to the installer, reducing the overall installation cost.
This streamlined application process is designed to ease the transition to greener heating solutions, contributing to reduced energy bills and supporting net-zero energy ambitions.

Getting a boiler on finance can be a good option if you're not ready to pay the full price upfront. It allows you to spread the cost over time, making it more affordable. However, it's essential to check the interest rates, as some finance options can add significant costs to the overall price. Compare different finance plans and ensure you can comfortably manage the monthly payments before committing.
Yes, many suppliers, including iHeat, offer payment plans for boilers. These plans allow you to spread the cost of installation over a set period, often with flexible terms. Some payment plans may come with interest, while others might offer 0% financing for a specific period. Always check the terms and conditions to find the best deal for your budget.
It can be more challenging to finance a boiler with bad credit, but it’s not impossible. Some lenders and boiler providers, like iHeat, may offer flexible finance options for people with less-than-perfect credit. You might be offered a higher interest rate or a shorter repayment term, so it’s important to review the terms and ensure you’re comfortable with the repayments.
Yes, you can get a boiler and pay monthly. Monthly payment plans make it easier for homeowners to manage the cost of a new boiler. Depending on the supplier and your credit history, you may be able to secure interest-free or low-interest monthly payments. Just make sure to check the details of the plan, including the repayment period and interest rates.
It’s possible to get a boiler with bad credit, but it might depend on the financing options available. Many boiler companies offer credit checks, and if your credit score is lower than usual, you may be offered financing with higher interest rates. Some companies specialise in providing finance for people with bad credit, so it’s worth shopping around for the best option.
In the UK, grants for new boilers are available to people who meet certain criteria, such as low-income households, pensioners, or individuals receiving certain benefits. Programs like the Boiler Upgrade Scheme (BUS) and the Energy Companies Obligation (ECO) scheme can provide financial help for replacing old, inefficient boilers with more energy-efficient systems.
If you can’t afford a new boiler, there are a few options available to help you manage the cost. You might be eligible for government grants, like the Boiler Upgrade Scheme or ECO, which can reduce the cost of replacing your old boiler. Alternatively, consider financing options that allow you to pay monthly, or get quotes from multiple suppliers to find the most affordable deal. If you're facing financial hardship, contact your energy provider for advice on available assistance schemes.
