EPC Rating F: A Home With a Lot to Gain

An EPC rating of F means your home is very inefficient. The good news is that homes at this level can gain the most from the right upgrades, and many qualify for help with the cost.

What does an EPC F rating mean?

F covers scores of 21 to 38 points on the SAP scale, the method used to score a home’s energy efficiency. A home rated F is close to the bottom of the scale. It usually means several problems at once, such as poor insulation, an old heating system and heat escaping through walls and the roof.

Can I get a grant with an EPC rating F?

F is within the range that ECO4 is aimed at, for both owners and private tenants.

  • Homeowners: you can qualify if you receive a qualifying benefit, or your council refers you through LA Flex.
  • Private tenants: you can qualify with your landlord’s permission.
  • Larger upgrades, such as solid wall insulation or first time central heating, are often part of a plan for a home at this level.

ECO4 is due to close on 31 December 2026, so check early.

Renting out a home rated F

Rented homes in England and Wales generally need to be rated E or better to be let, unless an exemption applies. A home rated F usually needs work before it can be let. Landlords should speak to us about what is possible.

Where do we start with an F-rated home?

We start with a free home survey. It shows where the heat is going, and in what order to fix it. For many homes that means insulation first, then heating, so that any new system is not working against a draughty building.

Frequently asked questions

How bad is an EPC rating F?

It is near the bottom of the scale. It means the home loses a lot of heat, but there is usually plenty that can be done.

Can I rent out a home with an F rating?

Not usually. Landlords in England and Wales generally have to bring an F-rated home up to at least E before letting it, unless an exemption applies.

Where do I start to improve an F rating?

A survey is the best first step. It shows which upgrades will make the biggest difference, and whether a grant can pay for them.

Can an F-rated home qualify for ECO4?

Yes, for homeowners and private tenants. You also need to meet the benefit rules or be referred by your council.
