The A to G scale · band by band

EPC rating F

SAP 21 to 38: below the letting floor. Not lettable in England and Wales without a registered exemption.

FSAP 21-38
Verdict: Blocked

Band F: you cannot let this without a registered exemption.

Bands F and G sit below the MEES floor of E that has applied to all domestic lets in England and Wales since 1 April 2020. Letting a sub-E property without a valid exemption on the PRS Exemptions Register risks penalties of up to £5,000 per property. Improve it to E or register an exemption first.

Band F is a SAP score of 21 to 38 GOV.UK SAP. For landlords it is the wrong side of the line: domestic property below band E cannot be let in England and Wales without a valid exemption on the PRS Exemptions Register GOV.UK MEES.

Letting a band F property

Without an exemption, letting an F is a breach. Penalties run up to £5,000 per property: up to £2,000 for a breach under three months, up to £4,000 beyond that, plus publication penalties GOV.UK MEES. Enforcement sits with local authorities. Selling an F is legal; only letting is restricted.

The exemption route

If you spend up to the £3,500 cost cap and the property still cannot reach E, you can register an all-relevant-improvements exemption, valid for 5 years GOV.UK MEES. Other routes cover third-party consent, devaluation and wall-insulation suitability; the exemptions page walks each one.

Getting an F to an E

F-rated homes usually have obvious gaps: no loft insulation, uninsulated walls, an old heating system, single glazing. That is bleak reading but useful, because the first measures on the certificate's recommendation list GOV.UK tend to move an F several SAP points at once. Only 9% of English dwellings remain in bands E to G combined EHS 2023-24, so the stock is emptying out below you.
