UK landlord compliance

How often do landlords need an EPC?

EPCs are valid for 10 years. A residential let needs at least band E today (MEES). Tighter C-rating proposals target 2028 for new tenancies and 2030 for existing. Here's what that means for your portfolio.

The short answer

A UK Energy Performance Certificate is valid for 10 years. You don’t need a new one annually — you need one when there isn’t a current EPC on file for the property, when the existing one expires, or when you’ve done significant works and want the higher rating reflected.

Minimum rating to let residentially is band E today under MEES. The government has proposed raising this to Cfor new tenancies from 2028 and all tenancies from 2030. The proposals have not yet been laid in final form — check GOV.UK before committing to major works on a fixed timeline.

The 10-year rule

When you actually need a new EPC

EPCs lodge on the central register and are valid for ten years from the assessment date. Letting a property without a current EPC on file (where one is required) is the offence — not failing to refresh an in-date EPC.

Practically, you need a fresh assessment in three situations:

  • No current EPC on fileMost likely on new acquisitions where the previous owner never let the property, or where the existing EPC has lapsed.
  • Existing EPC has expiredA 10-year-old EPC stops being valid for letting purposes. You can technically continue an existing tenancy without re-assessing, but you cannot start a new tenancy without a current EPC.
  • You’ve done material energy worksNew boiler, insulation, glazing, heat pump — the old EPC doesn’t reflect the upgrade. Most landlords commission a fresh assessment to get the higher rating onto the register.

Minimum rating to let

MEES: the rating you cannot let below

Minimum Energy Efficiency Standards (MEES) for the private rented sector have applied since 2018 (new tenancies) and 2020 (all tenancies). The current threshold is band E. Letting a property below E without a registered exemption is a civil offence — the local council enforces, with penalties up to £5,000 per property.

Enforcement is patchy but accelerating, particularly in cities with active selective licensing regimes (much of London, large parts of the North-West, parts of the Midlands). If your council can already see your rental properties via a selective licence, your EPC band is one click away.

The proposed move to band Cis the bigger issue. The government’s most recent consultation timeline targets:

  • From 2028: all new tenancies in England and Wales must have band C or higher.
  • From 2030: all existing tenancies must have band C or higher.
  • These dates have moved before. The regulations have not yet been laidin final form. Plan with a margin, but don’t commit to a fixed deadline before GOV.UK confirms one.

The practical workflow

What to do this quarter for every property

  1. 1. Check the current EPC and band

    Look up each property on Find an Energy Certificate (GOV.UK). Note the band and the expiry date.

  2. 2. Flag any property below D

    D and E properties are exposed if MEES tightens to C. Get a SAP-trained assessor or a Domestic Energy Assessor (DEA) to model the cheapest path to C — usually loft insulation, cylinder lagging, and LED lighting before structural moves.

  3. 3. Track the renewal date with everything else

    EPC renewal is one of six dates you need to track per property. Put it where you already track gas safety and EICR — same place, same expiry-warning rhythm.

Common questions

Questions, answered

Do I need a new EPC every year?+
No. An EPC is valid for 10 years. Once you have one for a property, you don’t need a new assessment until it expires — unless you make substantial changes to the property that would invalidate the rating, or you choose to re-assess after upgrades to evidence a better band.
What’s the minimum EPC rating to let in the UK right now?+
Band E for residential lets in England and Wales under MEES (Minimum Energy Efficiency Standards). Letting a property below E without a registered exemption is a civil offence with penalties up to £5,000 per property.
Is the MEES rating going up to C?+
The government has consulted on raising MEES from E to C for the private rented sector, with proposed timelines targeting 2028 for new tenancies and 2030 for existing. The dates have moved before and the regulations have not yet been laid in their final form. Check GOV.UK and your council before scheduling major works on the assumption of a fixed deadline.
Are there exemptions to MEES?+
Yes — limited and time-bound. The main ones: properties where all recommended improvements have been made and the rating is still below E (“all relevant improvements” exemption); properties where the works would devalue the property by more than 5% (independent surveyor evidence required); and listed buildings where works would alter the character unacceptably. All exemptions must be registered on the PRS Exemptions Register to be valid.
When should I get a new EPC if I’m upgrading the property?+
After the works are complete. The new EPC will reflect the improvements (new boiler, insulation, glazing) and gives you the higher rating to lean on at marketing time and with the lender. If the existing EPC still has years left, you don’t have to re-assess — but most landlords do, to get the rating reflected on Find an Energy Certificate.
