Many UK homes need better heating. A new boiler helps, but they can cost a lot of money. Luckily, the UK government gives free boiler grants to low-income families. These grants are part of the ECO4 scheme. 

They help people stay warm and save money. But not everyone can get a grant. You must meet certain income rules. This blog will explain what income levels qualify. It will also guide you through checking your eligibility and how to apply.

Why Income Matters for Boiler Grants

Boiler grants are for people who need help with heating. That usually means those with lower incomes. If your income is low, the government wants to support you. They offer grants so you can get a free or cheap boiler. They use income levels to decide who should get help first. This ensures people who need warmth the most get it. If your income is high, you may not qualify. That’s why knowing the limits is very important.

How Income is Checked for Boiler Grants

To qualify for a boiler grant, your income must be below a set amount. The amount depends on how many people live in your home. The government looks at total household income, not just one person’s. That includes wages, pensions, benefits, or other income. You may also need to show proof, like payslips or benefit letters. Installers check your documents before they approve the grant. If your income is too high, you may not qualify for help.

Exact Income Limits to Qualify in 2025

The income limits for boiler grants under ECO4 in 2025 are very clear. If your total household income is less than £31,000 per year, you may qualify. That amount includes all wages and benefits before tax. The limit stays the same no matter how many people live with you. So even if you live alone or with a big family, the income rule stays the same. If your income is above this, you can still check under other rules.

Flexible Eligibility by Local Councils

Sometimes, your income may be a little too high. But you can still qualify under “flexible eligibility.” This is a special rule under the ECO4 scheme. Local councils can help people who need support, even if they earn more than £31,000. They look at things like poor health, cold homes, or high energy bills. Each council has its own rules. You need to contact your local council to apply this way. They may send someone to check your home’s condition.

Income and Government Benefits Together

Some people don’t need to worry about income limits at all. That’s because getting certain benefits makes you automatically qualify. These include Universal Credit, Pension Credit, and Income Support. Other benefits like Child Tax Credit or ESA also count. If you get any of these, you likely qualify without checking income. You still need to show proof of the benefit. A recent letter from the Department for Work and Pensions (DWP) is usually enough to apply.

What if You Are on Minimum Wage?

If you work and earn minimum wage, you may still qualify. Many workers on low wages earn less than £31,000 a year. If your job is part-time, your income is likely low enough. Even full-time workers with kids or high bills may qualify. If you’re unsure, just add up your income for the year. You can also ask a grant provider to check it for you. They will tell you if you meet the rules before you apply.

What Counts as Household Income?

It’s important to know what income is counted. Household income includes your wages from work, even part-time jobs. It also includes pension payments and self-employment earnings. Government benefits are counted too, unless they are disability benefits. Child Benefit and Child Tax Credit also count. If someone else lives with you, their income is included. This means if you share a home, your combined incomes matter. Always include all earnings when checking your total household income.

Documents You Will Need to Prove Income

You’ll need to show documents when you apply for a boiler grant. These prove how much you earn. If you work, you can show payslips or a P60 form. If self-employed, use bank statements or a tax return. If you get benefits, use a DWP letter or Universal Credit screenshot. The documents must be recent. Installers or grant teams need to check them. Without proof, your grant may be delayed or refused. Keep your papers ready before applying.

If You Don’t Qualify by Income

If your income is too high, don’t worry just yet. You may still get help under local council rules. This is known as “ECO4 Flex.” Your council checks other things like health, energy bills, or how cold your home gets. Even working families can sometimes qualify. You can also look at other grants or schemes. Some energy suppliers offer help directly. Charities and local energy groups may also offer support. So, don’t give up if you don’t qualify right away.

How to Apply for a Boiler Grant

First, find a trusted ECO4-approved installer or grant website. Then, fill out the form with your details. Add your household income and any benefits you receive. Upload your documents for faster approval. A team will check if you qualify. If yes, they’ll book a free survey at your home. The installer will see if your current boiler can be replaced. If all goes well, you get a new boiler installed for free. The process is simple and quick.

Conclusion

Boiler grants are here to help low-income families stay warm. If you earn less than £31,000 a year, you likely qualify. Some people also qualify just by receiving benefits. Even if you earn more, your council may still help under special rules.  

Don’t miss your chance to save money, heat your home for less, and ensure your system works efficiently by understanding boiler pump overrun.
