Your funding route depends on your nation, proposed upgrade and the scheme’s actual eligibility rules. This guide is for homeowners checking whether a grant route deserves further investigation. It distinguishes the Boiler Upgrade Scheme from household-tested support and Scottish grant-and-loan funding. Treat the checks below as a starting point, not confirmation that your application will succeed.
For the broader overview, read our guide: Heat Pump Grant.
Independent guide. We are not a lender or a government body. Always check current scheme rules with the official provider.
1. Check the Boiler Upgrade Scheme route
The Boiler Upgrade Scheme covers England and Wales and does not use an income test. Your MCS-certified installer applies on your behalf rather than leaving you to arrange the grant alone. Published heat pump categories include air-to-water, ground source and air-to-air systems. The grant level depends on the category and applicable replacement circumstances. Confirm the full property and installation rules through GOV.UK before committing to the work.
Absence of an income test does not mean every home or proposal qualifies automatically. Ask the installer to explain which current scheme conditions apply to your project. Request a written quotation showing the proposed grant deduction and remaining contribution. Keep any unresolved eligibility point separate from a salesperson’s promise about approval. The official grant notice gives the categories and values, but it does not replace the complete application guidance.
2. Check household-tested support in England
Warm Homes: Local Grant is delivered through local authorities in England. Its supplied eligibility facts include an EPC rating from D to G and household income no higher than £36,000 or qualifying benefits. The low-carbon heating category provides up to £15,000 separately from the energy performance category. Ask your council how it checks your circumstances and proposed measures. Do not treat the category maximum as a guaranteed award.
Prepare the evidence the council actually requests rather than assuming every application uses the same document list. Ask how ownership or landlord circumstances affect the proposed work and contribution. The supplied landlord rules fund the first property fully, with a half contribution for additional properties. Confirm how the authority applies those rules to your case. A council decision should guide your next steps, not an unofficial agent’s assessment.
3. Check Scottish conditions before arranging work
Home Energy Scotland offers grant and interest-free loan support, subject to its complete conditions. MCS installation is required and funding is offered on a first-come basis. Do not start work before receiving the written offer. Offers are valid for up to nine months, so check the deadline on your own documents. Ask the scheme about the remote rural uplift rather than assuming your location automatically qualifies.
Contact Home Energy Scotland with your proposed technology and household circumstances before finalising an installation schedule. Keep its written answer with the survey, quotation and any requested evidence. If you live elsewhere, use the official advice route for your nation rather than transferring Scottish conditions. Welsh homeowners can also ask Nest about available support. Northern Ireland readers should seek official local advice instead of relying on the schemes described here.
- Identify your nation and proposed heat pump type.

Frequently asked questions
Does my income affect Boiler Upgrade Scheme eligibility?
The scheme does not have an income test. Other property and installation conditions still apply, so check the complete GOV.UK guidance.
Who applies for my Boiler Upgrade Scheme grant?
Your MCS-certified installer applies on your behalf. Ask how approval and the deduction appear in your quotation and payment arrangements.
What EPC rating does my Local Grant application need?
The supplied Warm Homes: Local Grant criteria cover EPC D to G. Confirm the council’s full household and property assessment before proceeding.
Can I assume my Scottish offer covers any installer?
No. MCS installation is required. Check the installer and the written offer conditions with Home Energy Scotland before work starts.
So you can investigate the right grant route without confusing initial checks with confirmed eligibility.
