Certification and Regulation Support

LP Energy produces Energy Performance Certificates and advises on the energy regulations that sit behind them, for developers, landlords, architects and project managers across Essex, Greater London and the Home Counties. We work to Approved Document L and the Minimum Energy Efficiency Standards (MEES), and we explain the result in plain terms: what the rating is, what it means for the project, and what to do about it.

Who this is for

  • Landlords and property owners who need to let or sell a building and must hold a valid EPC
  • Owners of lettings rated below the legal minimum who need to know the cheapest route to compliance
  • Developers and contractors who need EPCs and Part L evidence for new buildings, conversions and extensions
  • Occupiers of larger public or commercial buildings that need a Display Energy Certificate

What we provide

  • Domestic and non-domestic Energy Performance Certificates
  • Display Energy Certificates (DECs)
  • MEES compliance reviews and EPC upgrade advice, including costed improvement options
  • Part L glazing calculations (the 25% rule) for extensions and alterations
  • Advice on consequential improvements triggered by work to existing buildings
  • TM44 air-conditioning inspections

How it works

  1. You send us the building details and the purpose (letting, sale, new build, planning condition).
  2. We survey or model the building, depending on the type.
  3. You receive the certificate and, where it’s needed, a plain-English summary of the options for improving the rating.

Keeping up with the rules
EPC and MEES requirements are changing. At present, non-domestic buildings must generally reach EPC E to be let. In June 2026 the government confirmed it intends to require EPC B by 2031 for non-domestic buildings over 1,000 square metres, subject to a cost-effectiveness test. The legislation hadn’t been laid at the time of the announcement, so we check the current position for every client before advising.

Frequently asked questions

When is an EPC legally required for a commercial property, and what rating can it be let at?

An EPC is required when a non-domestic building is constructed, sold or let, and remains valid for 10 years. Under the Minimum Energy Efficiency Standards (MEES), landlords in England and Wales cannot let, or continue to let, a non-domestic property rated below EPC E unless a valid exemption is registered. Civil penalties are set by reference to rateable value and can reach 150,000 pounds. In June 2026 the government confirmed it intends to require EPC B by 2031 for non-domestic buildings over 1,000 square metres, subject to a 7-year payback test and exemptions, and dropped the earlier 2027 interim EPC C milestone. Smaller buildings stay at EPC E. The secondary legislation had not been laid at the time of the announcement, so check the current position before advising a client.
