What is an EPC?
An Energy Performance Certificate (EPC) details the building’s energy efficiency compared to a notional building with the same age and use characteristics. They are required for all leases, sales and purchases and are rated from A+ (highest) to G (lowest) with EPC’s below an E rating having restrictions placed on them for any lettings due to the Minimum Energy Efficiency Standards (MEES) regulations.


EPC’s are legally valid for 10 years, unless replaced earlier. Failure to provide an EPC can result in financial penalties.

The UK Government set a target for all commercial buildings to have a minimum C rating by 2027.
Why EPC’s are Essential
Since 2008, the Energy Performance of Buildings Regulations (2007) have required all UK properties sold, rented, or newly built to hold an A–G rated Energy Performance Certificate. From 2018, the Minimum Energy Efficiency Standards (MEES) mandate a minimum EPC rating of E for commercial buildings, with non-compliance (F/G) subject to fines and lease restrictions.
EPC’s are required for commercial buildings, domestic dwellings, new builds, and any rented or sold properties as specified by the Energy Performance of Building Regulations (2012). We provide EPC’s for multiple buildings:

Commercial Buildings

Industrial Estates

Commercial Warehouses

Office Buildings

Shops and Entertainment Venues

Data Centres

Hospitals and Surgeries

Historic and Specialised Buildings

Hotels and Hospitality Buildings

Public Houses and Restaurants
EPC ratings use a scale from A-G. A being the highest rating and G being the lowest. A higher rating means lower energy bills and a lower rating indicates a less efficient building with higher running costs.
- A+ & A: the highest ratings, A+ is for properties which have a net zero carbon usage
- B & C: Above Average and Average Efficiency respectively
- D, E & F: Below Average Efficiency
- G: The lowest rating for energy efficiency and below the MEES minimum standards

How Is Energy Performance Assessed?
Client Quote
To provide an accurate quote, we need the building’s location, floor area, and any supporting documents such as floor plans and specifications. Once reviewed, we’ll confirm the quote and arrange a site assessment.
Site Visit
A qualified energy assessor carries out a non-intrusive survey of the property, reviewing the buildings measurements, lighting, insulation, and HVAC systems to determine the property’s energy performance.
Assessment and Analysis
Collected data is entered into accredited EPC software which calculates the property’s energy rating based on current legislation. The assessment reflects the site visit, and a full QA audit is completed before the certificate is issued.
Certificate Provision and Publication
We produce the official Energy Performance Certificate, delivered digitally and registered with the National EPC Register for legal recognition and compliance.
Follow-up Support
We provide expert guidance on energy efficiency improvements through Compliance Modelling, helping owners understand enhancements and meet compliance requirements.
Evidence Re-inspection
We conduct a follow up visit to verify recommended energy improvements, review updated systems, and revise the buildings rating to reflect current performance for compliance and property transactions.
Not all properties are required to have an Energy Performance Certificate.
- Places of worship
- Temporary buildings (under 2 years intended use)
- Standalone buildings (under 50 m²)
- Buildings due for demolition
- Industrial sites and non-residential agricultural buildings
- Residential buildings to be used less than four months a year
- Listed buildings and those in conservation areas

Certain properties with ratings of F or G may qualify for exemption from MEES requirements.
- High-Cost — EPC upgrades outweigh property value
- 7-Year Payback — payback period exceeds 7 years
- All Improvements Made — rating below ‘E’ after improvements
- Wall Insulation — wall insulation structurally infeasible
- Consent — tenants refuse permission for improvements
- Devaluation — if upgrades significantly reduce property value
- New Landlord — allows time to plan improvements

Fines for failing to provide an EPC are calculated at 12.5% of the buildings value

The seven exemption criteria are set and must be registered by the PRS Register

Not providing an Energy Performance Certificate for a commercial property can lead to fines up to £5,000. Let us handle compliance and keep you aligned with current regulations.

We help improve energy ratings through detailed compliance modelling, identifying cost effective upgrades and practical measures to achieve your target performance level.

Whether through property transactions, rentals, or energy efficiency initiatives, our experts ensure you have an accurate and concise EPC rating, promoting sustainability and peace of mind.
