Free Boiler Replacement UK 2025 – Eligibility & How to Apply Before Deadline
With energy bills soaring, many UK households are struggling to afford heating. The good news? You might qualify for a free boiler replacement under government schemes like ECO4 and the Boiler Upgrade Scheme.
The deadline to apply is December 2025, so acting now could save you thousands. This guide explains eligibility criteria, how to apply, and key deadlines to secure your free boiler before time runs out.
Who Qualifies for a Free Boiler Replacement in the UK?
Not everyone is eligible—the schemes target low-income households, pensioners, and those receiving certain benefits. Here’s who can apply:
1. ECO4 Scheme Eligibility
The Energy Company Obligation (ECO4) requires energy suppliers to fund free boiler replacements for:
Households on income-related benefits (Universal Credit, Pension Credit, ESA, JSA, etc.)
Homes with an EPC rating of D, E, F, or G
Private tenants (with landlord approval)
Those referred by their local council under the ECO4 Flex scheme
2. Boiler Upgrade Scheme (BUS)
While not entirely free, BUS offers £7,500 grants for old gas boiler replacement with heat pumps. You may qualify if:
You own your home (landlords can also apply)
Your boiler is older than 10 years
Your property has a valid Energy Performance Certificate (EPC)
3. Warm Home Discount Scheme
This provides a one-time £150 discount on electricity bills, which can help cover heating costs if you’re on:
Pension Credit
Low income + high energy usage

Follow these steps to claim your free boiler before December 2025:
Step 1: Check Your Eligibility
- Visit the Chahal Energy Ltd website or use a free boiler grant checker online.
- Confirm if you’re on a qualifying benefit or meet ECO4 Flex criteria.
Step 2: Get an Energy Assessment
- A certified assessor will check your EPC rating and boiler condition.
- If your boiler is inefficient (G-rated or broken), you’ll likely qualify.
Step 3: Choose an Approved Installer
Only trusted ECO4-registered installers can fit your boiler for free. Avoid scams by:
- Checking installer credentials on the TrustMark website.
- Getting multiple quotes if applying under BUS.
Step 4: Submit Your Application
- Your installer will handle paperwork, but you’ll need to provide:
- Proof of benefits
- Property ownership/landlord consent
- Recent energy bills
Step 5: Boiler Installation
Once approved, installation takes 1-2 days. You won’t pay anything if fully eligible.
Deadline Alert: Apply Before December 2025
The ECO4 scheme ends in March 2026, but funding runs out fast. Similarly, the Boiler Upgrade Scheme may close earlier if demand is high.
