}What's in the commercial EPC database
EPC rating & asset score
The full EPC band (A–G) and underlying asset rating score. Includes both the current rating and the potential rating achievable with recommended improvements.
Property type & floor area
Building use type (office, retail, warehouse, hotel, school, healthcare, etc.) and total floor area in square metres. Used for benchmarking energy intensity across a portfolio.
MEES compliance flag
A pre-computed flag indicating whether the property meets the current band E minimum under the Minimum Energy Efficiency Standards. Properties rated F or G are flagged as non-compliant for commercial letting purposes.
Certificate date & assessor
Lodgement date, expiry date, and accredited assessor details. Useful for identifying stale EPCs approaching the 10-year expiry threshold, particularly relevant for portfolio managers ahead of lease renewals.
MEES for commercial properties: what landlords need to know
The Minimum Energy Efficiency Standards (MEES) Regulations require commercial landlords in England and Wales to hold an EPC rating of at least band E before granting or renewing a lease. Since April 2023, this applies to all existing commercial tenancies, not only new leases.
Properties rated F or G cannot legally be let to new tenants (with limited exemptions registered on the PRS Exemptions Register). Landlords who fail to comply face civil penalty notices of up to £150,000 and publication of non-compliance on the public register.
The Government has consulted on raising the MEES minimum for commercial properties to band C by 2027 (for new leases) and band B by 2030 for all commercial lettings. While final regulations have not yet been laid, many institutional landlords are already managing portfolios against these targets.
MEES exemptions are available for commercial properties where improvements are not cost-effective (the "seven-year payback" test), where a third-party consent cannot be obtained (e.g. listed building), or where the property has been marketed for six months. Exemptions must be registered and last for five years.
Screen your commercial portfolio for MEES compliance
Pass UPRN lists to the API to flag F and G-rated properties before lease events. Pay as you go, no subscription needed.
Who uses commercial EPC data
Commercial property funds & REITs
Portfolio-level MEES compliance screening across hundreds or thousands of assets. Identify assets at risk ahead of lease events and forecast capex requirements for EPC upgrades to meet the proposed band C and B deadlines.
Commercial agents & surveyors
Pre-populate EPC data in valuation reports and agency marketing brochures. Flag properties close to the 10-year certificate expiry to prompt landlords to commission updated assessments before they become an obstacle to letting.
Lenders & underwriters
Assess stranded asset risk in commercial property loan books. Properties with F or G ratings carry regulatory letting risk that directly affects security value. Automated API checks integrate into loan origination and annual review workflows.
Energy consultants & sustainability teams
Benchmark energy performance across a client's estate and prioritise improvement works by EPC improvement potential. The API returns both current and potential ratings, enabling improvement headroom calculations without recalling physical assessors.
Data source
The commercial EPC dataset is sourced from the MHCLG Non-Domestic EPC Register , which holds all non-domestic energy performance certificates lodged in England and Wales since the register's inception. The data is published under the Open Government Licence.
Non-domestic EPC assessments are conducted by accredited non-domestic energy assessors (NDEAs), qualified under the Building Regulations 2010. Assessor accreditation bodies include CIBSE, STROMA, Quidos, and others approved by the Secretary of State.
Homedata normalises and matches records to Ordnance Survey UPRNs for consistent address resolution, then applies MEES compliance logic as at the current regulatory threshold. The dataset is refreshed quarterly as new certificates are lodged.

What is a commercial EPC?
A commercial EPC (Energy Performance Certificate), formally called a non-domestic EPC, rates the energy efficiency of a commercial or non-residential building on a scale from A (most efficient) to G (least efficient). It is required when a commercial property is built, sold, or let. The certificate is valid for 10 years.
What are the MEES rules for commercial properties?
The Minimum Energy Efficiency Standards (MEES) for commercial properties in England and Wales require landlords to hold a minimum EPC rating of E before granting a new lease (since April 2018) or renewing an existing one (since April 2023). The Government has proposed raising this minimum to B by 2030 for non-domestic properties, though the timeline is subject to consultation.
How many commercial EPCs are in the database?
The MHCLG non-domestic EPC register holds approximately 1.4 million certificates for England and Wales, covering a wide range of commercial property types including offices, retail units, warehouses, schools, hospitals, and mixed-use buildings.
What is the difference between a domestic and non-domestic EPC?
A domestic EPC rates residential properties (houses, flats, HMOs). A non-domestic EPC, commonly called a commercial EPC, rates all other building types: offices, retail, industrial, hospitality, education, and healthcare. The methodology, assessor accreditation, and MEES thresholds differ between the two certificate types.
What is the difference between a domestic and commercial EPC?
A domestic EPC rates homes (houses, flats, HMOs). A non-domestic or commercial EPC applies to all other building types: offices, retail units, warehouses, schools, and so on. The assessment methodology, assessor accreditation pathway, and MEES regulatory thresholds are different for each. Homedata's commercial EPC API covers the non-domestic register only; domestic EPC data is available through the EPC data endpoint .
What are the current MEES rules for commercial properties?
Since April 2023, commercial landlords in England and Wales must hold a minimum EPC band E rating before granting a new lease or maintaining an existing tenancy. Properties rated F or G cannot be let without a registered exemption. The Government has proposed raising the minimum to band C by 2027 (new leases) and band B by 2030 for all commercial lettings, subject to final regulation.
Are there MEES exemptions for commercial properties?
Yes. Exemptions include situations where all relevant energy efficiency improvements have been made but the property remains below band E, where third-party consent (e.g. a listed building consent or superior landlord permission) cannot be obtained, or where the improvement works would not achieve a seven-year payback on cost. Exemptions last five years and must be registered on the PRS Exemptions Register.
Can I look up a commercial EPC by address rather than UPRN?
Yes. The API accepts address strings, postcodes, and UPRN inputs. Addresses are matched to the OS AddressBase UPRN index before the EPC record is retrieved, so you don't need to resolve UPRNs separately in your workflow.
