An EPC rating of F or G does not legally prevent you from selling, but it will limit your buyer pool and may affect the sale price.
The legal minimum standard for rented properties (EPC E) does not apply to sales; you can sell a home with any EPC rating (GOV.UK, 2026). However, many mortgage lenders will not lend on an F or G rated property, which restricts buyers to cash purchasers or those using specialist lenders. A 2026 DESNZ survey found that 68% of homebuyers consider energy efficiency a “very important” factor, meaning an F or G can significantly reduce market appeal (DESNZ, 2026).
Selling a home with EPC F or G is legal, but 68% of buyers value efficiency, limiting interest. Mortgage lenders often refuse these ratings, restricting sales to cash buyers or specialist lenders. Improve your rating with grants like GBIS or ECO4 to boost appeal.

The Energy Performance Certificate itself is a legal requirement for marketing, not a barrier to sale.
You must have a valid EPC (valid for 10 years) before listing your home for sale, regardless of the rating (GOV.UK, 2026). Selling without an EPC can lead to a £200 fixed penalty notice from your local authority trading standards department. The EPC provides a clear record of the property’s current energy efficiency; an F or G rating is simply a statement of fact, not a prohibition.
Quick numbers typical costs, savings, and grant limits for improving an F or G rating to an E or D.
| Improvement | Typical cost (2026, EST) | Typical annual saving (2026, EST) | Typical EPC band jump | Available grant (England, 2026) |
|---|---|---|---|---|
| Loft insulation (270mm) | £300–£600 | £150–£225 | 1–2 bands | Great British Insulation Scheme (GBIS) – up to £1,000 |
| Cavity wall insulation | £500–£1,500 | £200–£300 | 1–2 bands | GBIS – up to £1,500 |
| Solid wall insulation (external) | £8,000–£14,000 | £300–£500 | 2–3 bands | ECO4 – up to £10,000 (low-income) |
| New gas boiler (A-rated) | £2,500–£4,000 | £100–£200 | 1 band | Boiler Upgrade Scheme (BUS) – £5,000 off heat pump (alternative) |
| Solar PV (4kW system) | £5,000–£7,000 | £400–£600 (savings + SEG) | 1–2 bands | ECO4 – up to £5,000 (low-income) |

The direct answer you can sell an F or G rated home, but you must lower your asking price or improve the rating first.
There is no law prohibiting the sale of a home with an EPC F or G in England, Scotland, or Wales. The practical barrier is buyer finance; most high-street lenders require a minimum EPC rating of E for mortgage approval. If you choose not to improve, you must market to cash buyers, property investors, or those using specialist “retrofit mortgages” that accept lower ratings. Data from the 2026 English Housing Survey shows that homes with EPC F or G sell on average 12% slower than D-rated homes and at a 8–10% price discount (DESNZ, 2026).
Eligibility for free or subsidised improvements who can get grants to bring an F or G up to an E or D.
ECO4 (Energy Company Obligation) is available to homeowners and private tenants in receipt of qualifying benefits (e.g., Pension Credit, Universal Credit, Income Support). It covers insulation, heating upgrades, and solar PV. There is no income cap for F or G rated homes in low-income areas (Ofgem, 2026). The Great British Insulation Scheme (GBIS) is available to any homeowner with an EPC rating of D or below, regardless of income, for loft and cavity wall insulation only. Income-qualified households can also get solid wall insulation. The Boiler Upgrade Scheme (BUS) is available to any homeowner in England and Wales for replacing a fossil-fuel boiler with a heat pump. The £5,000 grant is not income-tested, but the property must have a valid EPC with no outstanding recommendations for insulation (GOV.UK, 2026). For eligibility checks, use the GOV.UK “Energy grants checker” tool or contact your local authority’s energy advice service. You do not need to be on benefits for GBIS or BUS.
How to verify an installer and confirm your improvements are valid for EPC re-rating.
All work funded by ECO4, GBIS, or BUS must be installed by a TrustMark-registered installer who is also MCS-certified (for heat pumps and solar) or PAS 2030-certified (for insulation) (TrustMark, 2026; MCS, 2026). To update your EPC after improvements, you must book a new assessment with an accredited Domestic Energy Assessor (DEA). Find one via the EPC Register on GOV.UK (GOV.UK, 2026). The new EPC must reflect the improvements; do not rely on the installer’s estimate. The DEA will inspect the work and recalculate the rating. For mortgage purposes, a new EPC with a D or E rating will typically unlock standard lending. Check with your lender’s criteria before marketing.
The minimum you must do if you proceed to sell without any improvements.
You are legally required to provide the EPC to any prospective buyer before exchanging contracts (GOV.UK, 2026). You must include the EPC rating and the report’s recommendations in your property listing on portals like Rightmove or Zoopla. You should be prepared to explain the energy costs to buyers, as an F or G home will have higher annual bills (EST estimates £2,500–£3,500 per year for a typical 3-bed semi) (Energy Saving Trust, 2026). Consider a pre-sale “retrofit assessment” from a qualified assessor to give buyers a clear, costed plan for improvements – this can reduce price discounting.
