EPC E current requirement, stranded assets, NDEA assessors and EPC validity

Non-domestic MEES (SI 2015/962 Part 3): from 1 April 2023, all commercial lettings in England and Wales must have EPC E or above — applies to existing leases in place, not just new grants. Sub-E commercial property: cannot lawfully be let; many commercial mortgage lenders now require EPC E as minimum; institutional funds increasingly exclude sub-E properties from mandates. Non-Domestic Energy Assessors (NDEAs): Level 3 (simple offices; retail; industrial — using iSBEM software); Level 4 (complex HVAC buildings — hotels; large offices — using DSM); Level 5 (data centres; hospitals; very large multi-story). Commercial EPC valid 10 years. New EPC required on change of tenancy or sale when existing EPC expires.

Proposed trajectory to EPC B by 2030, improvement measures and MEES exemptions

  • Proposed (not yet law): EPC C new leases April 2027; EPC C all leases April 2028; EPC B new leases April 2030; EPC B all leases April 2032
  • Institutional lenders and investors already pricing EPC B into underwriting — sub-C properties face capex requirements and value discount
  • Common improvements: LED lighting (50-80% energy reduction; £5-25/sqm; 2-5 year payback); VRF or ASHP HVAC upgrade; BMS installation or upgrade (10-30% saving); roof and wall insulation; solar PV
  • Exemptions (PRS Exemptions Register; valid 5 years): all EPC-recommended improvements made and still sub-E; third-party consent refused; RICS certificate — improvements would reduce market value by more than 5%; new landlord 6-month window
  • Civil penalty: up to £150,000 per property (higher than residential MEES — £5k/£30k); penalty does not void the commercial lease
  • Display Energy Certificates (DECs): actual metered energy performance; required for public buildings over 250 sqm; annual renewal over 1,000 sqm; 10-year for 250-1,000 sqm; failure to display — penalty up to £1,000

Frequently asked questions

What is the current commercial MEES requirement for commercial landlords?+

From 1 April 2023, commercial landlords in England and Wales cannot continue to let commercial property with an EPC rating below E (unless a valid exemption is registered). This applies to ALL existing commercial lettings — not just new leases granted after April 2023. A sub-E commercial property is a stranded asset: unlettable without a valid exemption, increasingly unmortgageable, and value-impaired. Civil penalty for breach: up to £150,000 per property.

What is the proposed commercial EPC trajectory to 2030?+

The government has proposed (subject to legislation — not yet law as of June 2026): EPC C for new commercial leases from April 2027; EPC C for all existing commercial lettings from April 2028; EPC B for new commercial leases from April 2030; EPC B for all commercial lettings from April 2032. These proposed dates require Parliamentary approval. Institutional lenders and investors are already pricing these targets into underwriting and investment mandates.

Is a Display Energy Certificate (DEC) the same as a commercial EPC?+

No. An EPC shows MODELLED (theoretical) energy performance based on the building's fabric and services (asset rating). A DEC shows ACTUAL metered energy performance (gas; electricity; heat from utility bills — operational rating). DECs are required for public authority buildings over 250 sqm, must be displayed publicly, and renewed annually (over 1,000 sqm) or every 10 years (250-1,000 sqm). Failure to display a DEC: civil penalty up to £1,000.
