EPC C 2030 Landlords: A London Action Plan
EPC C 2030 landlords have faced years of mixed messages. The good news is that the rules are now settled. In January 2026, the government confirmed a firm deadline. From 1 October 2030, almost every privately rented home in England and Wales must reach EPC Band C. This guide gives London landlords the confirmed facts, the real costs, and the cheapest route from D to C. You will learn what applies to you, what you must spend, and what to do first.
Is the EPC C 2030 deadline confirmed?
Yes, the deadline is confirmed. The government set it out in its Warm Homes Plan, published on 21 January 2026. From 1 October 2030, all privately rented homes in England and Wales must reach Band C. One single date now covers both new and existing tenancies.
This ends years of stop-start policy. An earlier plan required new tenancies to reach C by 2028. That split has now been dropped in favour of one clean deadline.
Parliament still needs to pass the final regulations. Even so, the direction is firm. Acting early is now the sensible choice.
What the EPC C 2030 rules mean for you
The change matters for every London landlord. Your property must reach Band C to stay lettable from 2030. Here is how the rules compare, now and then.
| Rule | Now | From 1 October 2030 |
|---|---|---|
| Minimum EPC rating | Band E | Band C |
| Cost cap per property | £3,500 | £10,000 |
| Maximum penalty | £5,000 | £30,000 |
| Tenancies covered | All | All (new and existing) |
Band E remains the legal minimum until 2030. Letting a home rated F or G is already unlawful without a valid exemption.
How much does it cost to reach EPC C?
Your spending is capped at £10,000 per property. Spend up to that cap without reaching Band C, and you can register an exemption. Spending from 1 October 2025 already counts toward the limit.
Helpfully, the cap covers more than just building work. The cost of your EPC assessment and retrofit advice count toward it. Lower-value homes get a reduced cap, set at 10% of the property value under £100,000.
According to government figures, average spending is expected to reach about £5,400. That sits well below the cap. Many D-rated London flats reach C for £1,000 to £4,000.
Miss the deadline without an exemption, and fines reach £30,000 per property. That is a sharp rise from the current £5,000 maximum.
What is the cheapest route from D to C?
Reaching Band C is usually simpler than landlords fear. Most D-rated homes need only a handful of targeted upgrades. The right order depends on your property type.
In our work across London, we often find a property is closer to C than its old certificate suggests. A fresh assessment regularly reveals two or three cheap wins that tip the score over the line.
Here are the upgrades that usually deliver the most points for the least money:
- Switch all lighting to LED across the property.
- Add or top up loft insulation to current standards.
- Insulate cavity walls where the construction allows it.
- Upgrade heating controls, such as a smart thermostat and zoning.
- Improve hot water cylinder insulation, or upgrade the boiler.
- Fit draught-proofing to doors, windows and floors.
- Replace old single glazing where the budget allows.
Solid-wall Victorian and Edwardian conversions are the harder cases. These can push costs toward the cap, so plan them early.
What grants can cut your costs?
Funding can reduce what you pay out of pocket. Several schemes support energy upgrades, though landlord eligibility is often limited. Check each scheme before you rely on it.
Three options are worth a look. The Boiler Upgrade Scheme offers a grant toward a heat pump. Local grants under the Warm Homes Plan target colder homes in many areas.
When can London landlords claim an exemption?
Some properties qualify for an exemption from Band C. You can register one if you reach the £10,000 cap without success. Exemptions also apply where consent is refused, or where the work would devalue the home.
Every exemption must be logged on the PRS Exemptions Register. Each one lasts five years and then needs review. Properties exempt under the old Band E rule will need a fresh assessment against the new standard.
What should London landlords do now?
Start planning while you have time and choice. Early action means cheaper quotes and less pressure as 2030 nears. Contractors will get busier and dearer closer to the deadline.
Follow these three steps to get ahead:
- Check your current EPC rating and its expiry date.
- Book a fresh assessment to find the cheapest route to C.
- Phase the work around your tenancy cycles to limit disruption.
Many older certificates understate a property’s true rating. A re-check can save you from spending on the wrong upgrades.
The bottom line for London landlords
Settled rules give you a real planning advantage. The EPC C 2030 deadline is fixed, the cap is clear, and most London homes can reach C affordably. Landlords who plan now will spend less and avoid the last-minute rush.

Confirmed in the Warm Homes Plan of January 2026, the deadline is 1 October 2030. All privately rented homes in England and Wales must reach EPC Band C by that date. It applies to both new and existing tenancies. The final regulations still need to pass through Parliament.
How much do landlords have to spend to reach EPC C?
Landlords must spend up to £10,000 per property to reach Band C. If you hit the cap without success, you can register an exemption. Spending from 1 October 2025 counts, and your EPC assessment and retrofit advice count too. Average spending is expected near £5,400.
What is the penalty for missing the 2030 deadline?
Penalties reach up to £30,000 per property for each breach. This is a steep rise from the current £5,000 maximum. Local authorities enforce the rules. You must either improve the property to Band C or register a valid exemption before the deadline.
Does EPC C apply to existing tenancies?
Both new and existing tenancies are covered. From 1 October 2030, every privately rented home in England and Wales needs Band C. An earlier plan to phase in new tenancies by 2028 was dropped. A single deadline now applies to all.
Can London landlords get an exemption from EPC C?
Exemptions exist for several situations. You can register one if you spend up to the £10,000 cap without reaching C. Others apply where consent is refused, or where upgrades would devalue the home. Each exemption lasts five years and must sit on the PRS Exemptions Register.
