If you are letting a property for the first time, an Energy Performance Certificate is not optional. Every rental property in England and Wales needs a valid EPC rating of E or above before a tenant can move in. From 1 October 2030, that minimum rises to C. This guide explains what that means, what it costs, and what you need to do.
What Is an EPC?
An EPC is an official document rating a property's energy efficiency on a scale from A (most efficient) to G (least efficient). It covers the building fabric, heating system, insulation, and glazing, then calculates a Standard Assessment Procedure (SAP) score. Properties scoring 69 or above are band C. Below 39 is band F or G.
According to EPCGuide's analysis of 29.2 million EPC records across England and Wales, 55.3% of all homes currently sit below band C. The share in the private rented sector is higher, because older stock is overrepresented in buy-to-let portfolios.
An EPC costs between £60 and £120 for a standard residential property. It is valid for 10 years and must be commissioned from an accredited assessor. You can find one via the government's accredited assessor register or through specialist EPC directories.
What EPC Rating Does a Rental Property Need Right Now?
The current legal minimum is EPC band E. This has been in force under the Minimum Energy Efficiency Standards (MEES) since 1 April 2020 for all private rented properties in England and Wales, including existing tenancies.
Properties rated F or G cannot be legally let unless a valid exemption is registered on the PRS Exemptions Register. Letting an F or G property without an exemption leaves you exposed to fines from the local authority.
If you are buying a property to let and it is currently rated F or G, you will need to improve it before you can market it to tenants, or register an exemption if there is a genuine reason improvements cannot be made.
What Is Changing in 2030?
From 1 October 2030, the minimum EPC rating for all private rented properties in England and Wales rises from E to C. This applies to both new tenancies and existing ones.
The government set this out in its January 2026 consultation response. Properties that achieve EPC C before 1 October 2029 using the current EER methodology will be treated as compliant until their certificate expires. The new Home Energy Model (HEM) measurement system is expected to become compulsory for EPCs from 1 October 2029, with a transition period for landlords.
For properties that cannot reach C despite spending up to the cost cap, a cost cap exemption can be registered. The cost cap is set at £10,000 per property (raised from £3,500 in the January 2026 government response). Spending this and still not reaching C makes you exempt from enforcement until a new assessment is triggered.
See the EPC C 2030 deadline guide for the full timeline and what the new Home Energy Model means in practice.
How Do I Get an EPC?
Commissioning one is straightforward:
- Find an accredited domestic energy assessor. Search via the government register or ask your letting agent to recommend one.
- Book the survey. A standard assessment takes 30 to 60 minutes. The assessor inspects insulation, heating, glazing, and controls.
- The assessor uploads results to the national EPC register and provides your certificate.
- Check the certificate for accuracy before listing the property. If the assessor has made an error (a room listed as unheated, or insulation not recorded), challenge it now.
For newly purchased properties: if the previous owner had an EPC done in the last 10 years, you can use that existing certificate. If it has expired or the property has changed materially, you will need a new one.
If you are not sure whether your property already has a valid EPC, search the national EPC register. It is free and publicly accessible.
What Happens If My Property Is Below the Minimum?
If your property is currently E, you are legally compliant. Focus on planning for the 2030 C deadline rather than immediate action.
If it is F or G, you need to act now. Your options are:
- Improve it to E. Most properties can reach E with relatively low-cost measures: loft insulation, cavity wall insulation, or a boiler upgrade. Get a quote from a retrofit assessor or check the recommendations section of your existing EPC.
- Register an exemption. If the property genuinely cannot be improved, or you have already spent the cost cap without reaching E, you can register on the PRS Exemptions Register. See the full guide to EPC exemptions for landlords.
- Consider selling. If the costs to improve are prohibitive and no exemption applies, selling may be the right call. This is explored in detail in the sell or upgrade guide.
Penalties for non-compliance under MEES can reach £30,000 per property under the proposed new enforcement regime. The current penalties sit lower, but enforcement is increasing as local authorities receive more guidance. See EPC fines for landlords for the full picture.
How Much Will It Cost to Reach EPC C?
The government estimates the average cost of reaching C is between £6,100 and £6,800 per property (January 2026 consultation response). That average covers everything from properties one improvement away from C to those needing multiple measures.
In practice, the cost depends heavily on the property type and starting band:
| Starting band | Typical improvement path | Estimated cost |
|---|---|---|
| D | Loft insulation top-up, heating controls | £500 to £2,500 |
| E | Cavity wall insulation, boiler upgrade | £1,500 to £5,000 |
| F | Solid wall insulation or major heating upgrade | £5,000 to £10,000 |
| G | Multiple measures, possibly full retrofit | Up to £10,000+ |
The cost cap of £10,000 is a ceiling on what you are required to spend. If you spend £10,000 and still cannot reach C, you qualify for an exemption rather than having to spend further.

What Grants Are Available?
Two main schemes are open to landlords:
ECO4
The Energy Company Obligation (ECO4) funds insulation and heating improvements for properties with low-income tenants. Grants cover up to £14,000 per property. Eligibility is based on your tenant's household income or benefit status, not yours.
ECO4 closes 31 December 2026. This is now a hard deadline. If your property has D, E, F, or G-rated insulation and your tenants are on low incomes or benefits, check eligibility now. Applications through ECO4 do not run quickly. See the ECO4 landlord guide for eligibility criteria and how to apply.
Boiler Upgrade Scheme
The Boiler Upgrade Scheme (BUS) offers £7,500 towards the installation of an air source heat pump and £5,000 for biomass boilers. Landlords are eligible, and the EPC requirement was removed in April 2026, meaning you can now apply regardless of your property's EPC rating. The scheme runs to 2030.
For properties where heating is the main barrier to reaching C, BUS can be the difference between a compliant property and an exemption claim. See the BUS application guide for landlords.
What This Means for You as a New Landlord
The core checklist for any new landlord:
- Confirm the property has a valid EPC (E or above) before marketing it to tenants.
- Give tenants a copy of the EPC at the start of the tenancy.
- Note the expiry date. If your EPC expires during a tenancy, you will need to renew it before re-letting.
- Plan for 2030. If your property is D or E, you have time, but the closer you get to 2030 the longer contractor waiting lists will become. Start planning now.
- Check grant eligibility early. ECO4 closes at end of 2026. If you might qualify, this is your window.

Frequently Asked Questions
What is the minimum EPC rating to rent out a property in England? The current minimum is band E. This applies to all private residential tenancies under assured, regulated, or domestic agricultural tenancies that legally require an EPC. Properties rated F or G cannot be let without a valid exemption registered on the PRS Exemptions Register.
When does the EPC C requirement come in for landlords? From 1 October 2030, all private rented properties in England and Wales must meet EPC band C or above. This applies to both new and existing tenancies simultaneously. The equivalent deadline in Scotland is different and is still under consultation.
How much does an EPC assessment cost? Typically £60 to £120 for a standard residential property. Costs vary by property size and location. The EPC is valid for 10 years. You must use an accredited domestic energy assessor.
Can I rent out a property with an EPC D rating? Yes. EPC D is above the current minimum of E, so a D-rated property can be legally let. However, you will need to upgrade to C by 1 October 2030 to remain compliant.
What happens if I cannot afford to improve my property to EPC C? The government has set a cost cap of £10,000. If you spend up to this amount and cannot reach C, you can register a cost cap exemption on the PRS Exemptions Register. You are not required to spend beyond the cap. Exemptions last until a new EPC is triggered.
Are there grants to help landlords reach EPC C? Yes. ECO4 covers up to £14,000 for eligible properties (closes 31 December 2026). The Boiler Upgrade Scheme offers £7,500 towards a heat pump. Local authority schemes and warm home grants also exist for some areas. Grant stacking is permitted in certain circumstances.
