EPC Minimum Rating for Landlords 2026: What the Rules Mean for You

The current minimum EPC rating for a private rented property in England is **E**. Properties rated F or G cannot legally be let to new tenants, and since April 2020 this applies to existing tenancies as well.

If your property has an EPC rating of F or G, you cannot legally continue letting it until either:

1. You carry out energy-efficiency improvements to bring it to at least an E rating, or 2. You register a valid exemption with the PRS Exemptions Register (for cases where improvements are not technically or financially feasible)

Fines for letting an F or G rated property are up to £5,000 per property.

This is no longer a proposal. The government confirmed in January 2026 that **from 1 October 2030, almost every private rented home in England and Wales must reach EPC band C** to be let legally, unless a valid exemption applies.

Two details matter, because earlier guidance (including ours) described a different scheme:

• **The 2028 interim deadline was dropped.** For a long time the plan was that new tenancies would have to meet band C from 2028, with existing tenancies following later. That staged approach is gone. There is now a single date — 1 October 2030 — and it applies to new and existing tenancies alike.
• **There is a £10,000 cost cap.** Landlords are not expected to spend without limit. Once you have spent up to £10,000 on improvements, an exemption can be registered if the property still falls short.

Penalties for letting a non-compliant property run to **£30,000**.

What this means for your property:

• Rated **C or above** — you already meet the 2030 standard
• Rated **D or E** — legal to let today, but not from 1 October 2030 without improvements or a registered exemption
• Rated **F or G** — you cannot legally let it now, let alone in 2030

One further change worth planning around: EPC assessments are moving from the current SAP methodology to the new HEM method, phasing in from 2027 and fully in force by 1 October 2029. A property assessed under the new method may not score identically to its current certificate, so if your EPC is close to the band boundary it is worth reassessing nearer the time rather than assuming today's rating carries over.

Insulation, heating upgrades and heat pumps take planning and lead time. 2030 sounds distant, but for a portfolio it is not.

An EPC rates a property from A (most efficient) to G (least efficient) based on:

• Wall, floor and roof insulation
• Glazing type (single/double/triple)
• Heating system type and controls
• Hot water provision
• Lighting (LED vs traditional)
• Renewable energy sources (solar panels, heat pumps)

The assessment is carried out by an accredited domestic energy assessor (DEA), who conducts a non-intrusive survey — no drilling or removing panels, just a visual inspection and measurement. An EPC is valid for 10 years, but you can commission a new one at any time if you've made improvements you want reflected.

The most cost-effective improvements for London rental properties (in rough order of impact) are:

Loft insulation — the single biggest improvement for properties with an uninsulated loft. Can move an E to a D or C for under £1,000.

Cavity wall insulation — effective for 1930s–1980s solid or cavity-wall houses. Less relevant for solid Victorian stock.

Boiler upgrade — replacing an old G-rated boiler with a modern A-rated condensing boiler makes a meaningful difference to heating efficiency.

Heating controls — programmer + room thermostat + thermostatic radiator valves can add 2–4 EPC points with no structural work.

LED lighting — switching all fixed lighting to LED is low-cost and improves the rating.

Double glazing — major improvement for single-glazed properties, though expensive in London's period stock.

We can arrange a new EPC assessment to show the impact of improvements already made, or an advisory assessment to identify the most cost-effective route to C.

EPC assessments at Landlord Compliance London start from £99.99 for a studio (up to £159.99 for a 5-bedroom property), all prices include VAT.

The assessment typically takes under an hour. Your certificate is lodged on the national EPC register and emailed to you within 24 hours of the assessment. It's valid for 10 years.
