Frequently asked questions

Is my EPC F rated home eligible for grants in Portsmouth?

Yes. EPC F rated homes are among the highest priorities for Warm Homes Plan funding. If your Portsmouth home is rated F and your household receives a qualifying benefit, you are very likely to be eligible for significant funded improvements. Submit the form to confirm your eligibility.

What does an EPC rating of F mean?

An EPC rating of F means your home scores between 21 and 38 on the energy efficiency scale. This indicates very poor insulation and high energy costs. EPC F properties are in fuel poverty territory for many households, which is precisely why they are prioritised for Warm Homes Plan funding.

What improvements could an EPC F home in Portsmouth receive?

EPC F homes typically require multiple measures to bring them to an acceptable energy standard. Common funded improvements include solid or cavity wall insulation, loft insulation, heating system upgrades, and potentially solar panels. A free survey will identify the full package appropriate for your property.

How much improvement in EPC rating can I expect after funded works?

Many EPC F homes that receive a full package of Warm Homes Plan measures move to a D or C rating, representing a substantial reduction in energy bills and significant improvement in home comfort. The installer will provide an estimated post-improvement EPC rating before work begins.

What if I am a landlord with an EPC F rental property?

Private landlords are required by law to bring rental properties to at least EPC E before letting them (with limited exemptions). EPC F properties cannot legally be let without an exemption. The Warm Homes Plan has a landlord route that can fund the required improvements. Submit the form to explore your options.

Is the eligibility check free?

Yes. The form is free and takes about 60 seconds. If you pre-qualify, an accredited installer in Portsmouth will contact you to arrange a free survey.

What types of property in Portsmouth are eligible?

Most residential property types in Portsmouth can qualify, including detached houses, semi-detached houses, terraced houses, bungalows, and some flats. The property must be your main residence or a rental property where you have landlord permission. Eligibility also depends on your current EPC rating and heating system.

Is this an official government service?

UK Home Grants is an independent eligibility service operated by Stubo Interactive. We are not affiliated with DESNZ, Ofgem, or any government department. We connect homeowners with accredited installers who administer grants under the Home Energy Grants for EPC Rating F Homes. The grants themselves are government-funded.
