Introduction
An Energy Performance Certificate (EPC) provides important information about the energy efficiency of a commercial property. When buying commercial property at auction, reviewing the EPC rating can help you understand the likely running costs of the building and whether any improvements may be required in the future. This section explains how EPC ratings work and why they are an important consideration when assessing auction properties.
Commercial EPC
An Energy Performance Certificate measures the energy efficiency of a building and provides recommendations for improving performance. The EPC includes information about heating systems, insulation, lighting efficiency and overall environmental impact.
Under current regulations, the seller is generally responsible for ensuring that a valid EPC is available when a commercial property is marketed for sale. When buying at auction, a copy of the EPC is usually included in the legal pack or made available by the auctioneer prior to the auction date.
EPC ratings range from:
- A — Most energy efficient
- B
- C
- D
- E
- F
- G — Least energy efficient
Newer buildings or recently refurbished properties often achieve higher ratings, while older buildings may have lower energy performance depending on construction type and building services.
Minimum energy efficiency standards (MEES)
Energy performance has become increasingly important due to regulatory requirements affecting commercial property lettings. Under Minimum Energy Efficiency Standards (MEES) regulations in England and Wales, most commercial properties must achieve a minimum EPC rating of E in order to be legally let, unless an exemption applies.
Properties with ratings of F or G may require improvement works before they can be leased to tenants. Buyers considering investment purchases should therefore assess whether the property complies with current regulations and whether future upgrades may be required.
Government policy proposals indicate that minimum energy standards may tighten further over time, which could increase the importance of energy efficiency when assessing long-term property value.
EPC considerations when buying at auction
When reviewing an auction property, buyers should consider:
- The current EPC rating
- Whether improvement recommendations have been provided
- Potential costs of upgrading energy performance
- Whether the property is currently compliant with letting regulations
- Future regulatory risk
For investment properties, energy efficiency can affect tenant demand, rental value and operating costs. For owner-occupiers, EPC ratings may influence energy bills and refurbishment planning.
Improving energy performance
Where a property has a lower EPC rating, improvements may include:
- Upgrading heating or cooling systems
- Improving insulation
- Installing more efficient lighting
- Enhancing building controls
- Replacing older building services
A qualified energy assessor or building consultant can advise on potential improvements and likely costs.
Professional Advice
If you are unsure about the implications of an EPC rating, it may be helpful to seek advice from an energy consultant or building professional. Understanding the relationship between energy efficiency, running costs and compliance requirements can assist in making informed purchasing decisions.
