Energy efficiency rules for rented homes are changing and if you’ve felt lost in the exemptions, grants and 2030 talk you’re not on your own.
With around 2.5 million rented homes in England and Wales still below an EPC C the landlords who get ahead of this now will thank themselves later. Here’s everything that is needed in plain English.
Where things stand today
Since 1 April 2020 every private rental in England and Wales has needed a minimum EPC rating of E.
Let a property rated F or G without a registered exemption and you’re breaking the law and risking a fine.
Who does this apply to?
Assured tenancies (including ASTs), regulated tenancies and assured agricultural occupancies. It doesn’t apply where rent is under £250 a year or the property isn’t the tenant’s main home.
When do you actually need an EPC?
Whenever the property is let, sold or has had building regs work done within the last 10 years.
A handful of property types are exempt altogether listed buildings where efficiency work would spoil their character, short term temporary buildings, holiday homes used under 4 months a year and standalone buildings under 50m².
Quick answers to what landlords ask us most:
- My non self contained bedsit doesn’t need an EPC, am I still caught? Possibly, if the building as a whole needs one.
- My EPC’s lapsed and I haven’t relet do I need a new one? No, not until you next let or sell.
- Renewing a tenancy — new EPC needed? Yes, unless it rolls onto a contractual periodic tenancy in which case the EPC can lapse until you next renew or change tenants.
- Regulated tenancies? Technically in scope but since new ones can’t be created any more they’re rarely affected unless the property’s sold or a sitting tenant is succeeded by an assured tenant.
The big one: EPC C is now confirmed for 2030
This isn’t a proposal any more. In January 2026 the Government’s Warm Homes Plan confirmed it, from 1 October 2030 every privately rented home in England and Wales must hit EPC C (or an accepted equivalent) one single date for new and existing tenancies alike.
You’ll be compliant if you have one of the following:
- A valid EPC rated C or above under the current system. These ratings stay valid until October 2029 and since certificates last 10 years some landlords could rely on a pre 2029 C rating right up to 2039.
- A valid EPC meeting the new efficiency standard (see below) expected to launch from October 2026.
- A registered exemption — most commonly for having spent up to the £10,000 cost cap having made all viable improvements or where solid wall insulation is the only option left.
Miss all three by October 2030 and you can’t legally let the property until you do.
How the new EPC will work
Rather than one A–G score the new style EPC will score properties across separate metrics. The two that matter for landlords:
- Fabric performance (insulation, glazing, heat retention) — your priority, and roughly in line with today’s standards.
- Then either smart readiness (smart meters, batteries, solar) or heating system (heat pumps score well, gas boilers don’t).
You need a C in fabric performance plus one of the other two. Can’t get there? You’ll need an exemption.
Exemptions available under the new rules
- Cost cap — spent up to £10,000 (works from October 2025 onwards count plus your EPC fee) and still can’t reach C.
- Solid wall insulation — your call whether to fit it.
- Low property value — if your property’s worth under £100,000 you won’t be expected to spend more than 10% of its value.
Plus the existing exemptions still apply: all cost effective improvements made works that wouldn’t pay back within 7 years third party consent refused or the work would devalue the property by 5%+. New landlords inheriting a sitting tenant get a 6 month grace period to sort compliance or register their own exemption.
Every exemption must be registered on the PRS Exemptions Register — miss this step and it doesn’t count, exemption or not. And exemptions don’t transfer with a sale; a new owner has to re-register.
What this means for your EPC timeline
- Have an EPC C already? You’ve got until September 2029 before you need to renew but do a few small tweaks anyway, since the calculation methods are shifting and margins can be tight.
- Close to a C? Worth improving now and timing your renewal near September 2029.
- A long way off? It may be worth waiting for the new Home Energy Model EPC before committing to expensive works, so you can target your spend properly.
- Already got solar panels or electric heating? The new EPC is expected to favour these over gas boilers you may find your rating improves once it launches.
Making the improvements count
Work through your EPC’s recommended list insulation, solar, low energy lighting, draught proofing, glazing prioritising fabric performance first since smart readiness and heating upgrades won’t count toward your cost cap until fabric work is done (or the cap’s maxed out). A typical upgrade to C runs £6,000–£12,000, though grants are available especially for tenants receiving benefits.
Who enforces this, and what’s the penalty?
Local authorities enforce MEES, and they don’t hold back on detail once they’re involved. Here’s what’s on the table:
| Breach | Penalty |
| Giving false or misleading info to the PRS Exemptions Register | £1,000 + published as non-compliant |
| Ignoring a compliance notice from your local authority | £2,000 + published as non-compliant |
| Letting a non-compliant property (under 3 months) | £2,000 fixed + published as non-compliant |
| Letting a non-compliant property (3 months or more) | £4,000 fixed + published as non-compliant |
Beyond the fixed penalties further ones can stack up to £5,000 per property if you carry on letting non compliantly triggered again if the tenant changes or the regulatory backstop kicks in.
Disagree with a penalty?
You’ve got options. First ask the local authority to review its own decision they’ll consider what you’ve put forward and the full circumstances then either confirm the penalty or withdraw it if they’re not satisfied you actually breached the rules (or that a notice wasn’t appropriate in your case).
Still think it’s wrong after that? You can appeal to the First Tier Tribunal (General Regulatory Chamber) on the grounds the notice was issued in error doesn’t comply with the regulations or simply wasn’t the right call given your circumstances.
The bottom line:
The 2030 EPC C rule is now locked in not a maybe. Whatever state your portfolio is in, there’s a sensible next step and the earlier you take it the more choice (and the less cost) you’ll have.
