Check if you qualify for free home insulation or heating upgrades
ECO4 funding covers insulation and heating upgrades for eligible households at no cost. The Boiler Upgrade Scheme offers up to £7,500 towards heat pump installation — though most homeowners contribute towards the remaining cost. Answer a few questions and we'll identify which route may apply to you.
Heat Checker is an independent eligibility checking service — not a government website or installer. Results are indicative only.

£7,500 heat pump grant — available regardless of income

This takes about 2 minutes. Your result is an initial estimate, not a final grant decision.
What is your property status?
Both homeowners and renters can qualify for ECO4. Your status helps us identify the right route for you.
Do you or anyone in your household currently receive any of these benefits?
Receiving any of these benefits is the main route to fully funded ECO4 upgrades — insulation, boiler replacement, or heat pump — at no cost to you.
If energy improvements were available for your home, would your landlord or housing provider allow them to be carried out?
ECO4 works require landlord consent for rented properties. Most landlords support energy improvements — they improve the property's EPC rating and reduce tenant energy bills.
What type of property is it?
Property type affects which energy efficiency measures may be suitable.
What is your current heating system?
This helps estimate whether your current setup could be suitable for replacement or upgrade.
What is your postcode?
We use this to identify whether we may be able to match you with an installer in your area.
When are you looking to upgrade?
This helps us prioritise enquiries and understand intent.
Would you be willing to consider contributing towards the cost if eligible for the grant?
The Boiler Upgrade Scheme provides up to £7,500 towards a heat pump installation. However, total installation costs typically range from £10,000 to £25,000 depending on your property — meaning most homeowners contribute £5,000 to £15,000 or more towards the final cost.

Privacy Policy
Last updated: March 2026
Heat Checker is a lead generation service that helps connect homeowners with installer partners. We collect personal data you provide through the eligibility checker, including your name, email address, phone number, postcode and property details.
How we use your data
We use your data to assess your enquiry, store submissions, and where you consent, share your details with installer partners for the purpose of discussing a possible heat pump installation.
Property data lookup
When you provide your postcode and house number as part of the eligibility checker, we may automatically look up your property's Energy Performance Certificate (EPC) rating using the UK Government's EPC register (epc.opendatacommunities.org). This lookup is carried out to help assess your property's likely suitability for energy upgrade schemes, and the result is stored alongside your enquiry. No additional personal data is collected or shared as part of this process.
Important note
Heat Checker is not a government body, installer, or financial adviser. Checker results are indicative only and do not guarantee grant eligibility or installation suitability.
