Buying a boiler on finance can be hard with all the different options available. Let us explain all this in plain English for you.

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.
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.

The value of getting a boiler on finance is subjective and depends on an individual's financial situation. For some, the ability to spread the cost of a new boiler over some time can make it more manageable and less of a financial burden. It allows for immediate installation and usage without needing a large upfront payment. However, it's important to consider the interest rates and ensure the monthly repayments are affordable.
Yes, it is possible to buy a boiler and pay for it in monthly instalments. Many companies, including iHeat, offer boiler finance options that allow you to spread the cost of your new boiler over a period of time. This can make the purchase more manageable, particularly if you are faced with the unexpected cost of replacing a broken boiler.
Absolutely, you can buy boilers on finance. Many boiler manufacturers and suppliers offer finance options to make the cost of a new boiler more manageable. This can be particularly useful if your boiler breaks down unexpectedly and you need to replace it quickly. With a finance plan, you can spread the cost of your new boiler over some time, making it more affordable.
Yes, the UK government has set up schemes like the Energy Company Obligation (ECO) that can provide eligible households with boiler grants to replace old, inefficient boilers. However, these are subject to certain conditions, such as income, the current state of your boiler, and the type of property you live in. It's always worth checking to see if you're eligible for any government assistance when replacing your boiler.
Buying a boiler on finance can have several benefits. Firstly, it allows you to spread the cost of the boiler over some time, making it more affordable. Secondly, it can enable you to upgrade to a more energy-efficient model, which could save you money on your energy bills in the long run. Finally, it means you can have the boiler installed immediately rather than having to wait until you've saved up enough money.
When you buy a boiler on finance, you essentially take out a loan for the cost of the boiler. This loan is then repaid over a set period of time in monthly instalments. The exact terms of the finance agreement, including the interest rate and length of repayment period, can vary depending on the provider and your credit rating. It's important to read the terms and conditions carefully before entering into a finance agreement.
Getting a boiler on finance with bad credit can be more challenging, but it's not impossible. Some finance providers may still offer you a finance deal, but the interest rates may be higher. It's important to shop around and explore all your options. Also, improving your credit score can increase your chances of getting a better finance deal.
There are several finance options available when buying a boiler. These include interest-free credit options, buy now, pay later schemes, and longer-term finance plans with interest. The best option for you will depend on your financial circumstances and the price of the boiler you wish to purchase. It's important to compare different finance options to ensure you choose the one that's most affordable for you.
