Quick Answer
A commercial EPC (Energy Performance Certificate) typically costs from around £150 for a small, simple unit to £800 or more for a large building with complex heating and cooling, plus VAT. You need one whenever a commercial property is built, sold or let, and it must be shown to prospective buyers or tenants. It’s valid for ten years. Under the Minimum Energy Efficiency Standards (MEES), let commercial property in England and Wales must currently have a rating of at least E. In summer 2026, the government dropped plans to raise this to C in 2027, and instead proposed a minimum of B from 2031 for let buildings over 1,000 square metres, where cost-effective. That still needs new legislation. Fines for letting a non-compliant building can reach £150,000.
Why Your EPC Matters More Than Ever
Not so long ago, an EPC was a box-ticking exercise. You got one because the agent asked for it, filed it away and forgot about it.
Those days are over. Your EPC now affects whether you can legally let your building, how easily you can sell it, what a lender will offer and what tenants are willing to pay. A poor rating can leave a building empty, and a good one can make it the first choice on the street.
Think of your EPC as your building’s fuel economy rating. Buyers and tenants look at it before they look at anything else, because it tells them what the building will cost to run and how future-proof it is.
At Rory Mack Associates, we help landlords and owners across Stoke-on-Trent, Staffordshire, Cheshire and Shropshire understand their EPC, stay compliant and plan improvements. Here’s what you need to know.
What Is a Commercial EPC?
A commercial EPC rates the energy efficiency of a non-domestic building on a scale from A+ (net zero carbon) to G (least efficient). Unlike a home EPC, it’s based mainly on the building’s estimated carbon emissions, looking at its construction, insulation, heating, cooling, ventilation, lighting and hot water.
Every EPC comes with a recommendation report, listing improvements that could raise the rating.
When do you need one?
You need a valid EPC when a commercial building is:
- Built
- Sold
- Let to a new tenant
The seller or landlord must make the EPC available, free of charge, to prospective buyers or tenants at the earliest opportunity, and in any event when written information about the building is provided, when a viewing takes place, and before a contract is entered into. In practice, get it before you start marketing.
Some buildings are exempt, including places of worship, temporary buildings intended for less than two years, some industrial sites and workshops with low energy demand, and buildings due to be demolished.
Who is responsible?
The seller or landlord. They’re liable for the penalty if an EPC isn’t made available, not the agent. A good agent will remind you, though.
The penalty for failing to provide a commercial EPC is usually 12.5% of the building’s rateable value, with a minimum of £500 and a maximum of £5,000, or £750 where that formula can’t be applied.
How Much Does a Commercial EPC Cost?
The price depends on the building’s size and how complex its systems are. As a rough guide, before VAT:
| Building type | Typical cost |
| Small, simple units, such as a shop or small office | From around £150 to £250 |
| Buildings with air conditioning or more complex systems | Around £225 to £400 |
| Large or highly complex buildings | From around £400 to £800 or more |
You can keep costs down by giving the assessor floor plans and details of the heating, cooling and lighting systems before the visit.
Cheap isn’t always best. A rushed assessment with missing information can produce a lower rating than the building deserves, which could cause problems with letting.
How long is an EPC valid for?
Ten years. But if you’ve improved the building, for example with new heating, LED lighting or insulation, it’s often worth getting a new EPC early to reflect the better rating.
The Minimum EPC Rating for Commercial Property (MEES)
The Minimum Energy Efficiency Standards, known as MEES, set the lowest EPC rating a privately rented commercial building can have in England and Wales.
The rules today
- The minimum rating is E.
- Since April 2018, landlords can’t grant a new lease, or renew one, on a building rated F or G.
- Since April 2023, landlords can’t continue to let a building rated F or G either, even part-way through an existing lease, unless a valid exemption is registered.
- The rules generally don’t apply to leases of six months or less, or of 99 years or more.
What’s changing
You may have read that the minimum would rise to C in 2027 and B by 2030. Those were proposals from an earlier consultation and never became law.
In summer 2026, the government published an interim response that changed course:
| Earlier proposal | 2026 interim response | |
| 2027 | Minimum of C | Dropped |
| Long-term target | Minimum of B by 2030 | Minimum of B from 2031 |
| Which buildings | All let commercial buildings | Let commercial buildings over 1,000 square metres, where cost-effective |
| Smaller buildings | B by 2030 | Stay at E, with no new deadline set |
A seven-year payback test is expected to stay, so works wouldn’t be required where their cost is greater than seven years of expected energy savings.
This is not yet law. It needs new regulations to pass Parliament, and a full government response is expected. Until then, E remains the minimum. Larger buildings should still start planning now, because reaching B can take several rounds of work and may need to be timed around lease events.
Exemptions
A landlord may be able to let a building rated below E if a valid exemption is registered on the government’s PRS Exemptions Register. The main ones are:
- All relevant improvements made: every improvement that pays for itself within seven years has been done, and the rating is still below E
- Consent: a tenant, superior landlord, lender or planning authority has refused consent for the works
- Devaluation: an independent surveyor confirms the works would reduce the building’s market value by more than 5%
- New landlord: a temporary six-month exemption for someone who has just become the landlord
Most exemptions last five years and can’t be passed on to a new owner. They must be supported by evidence, such as quotes or a surveyor’s report.
Penalties
Local councils enforce MEES. For commercial property, the fines are based on rateable value:
| Breach | Penalty |
| Let in breach for less than three months | 10% of rateable value, minimum £5,000, maximum £50,000 |
| Let in breach for three months or more | 20% of rateable value, minimum £10,000, maximum £150,000 |
| Providing false or misleading information on the exemptions register | Up to £5,000 |
The lease stays valid even if the landlord is fined, so the tenant still pays rent. But the landlord is left with a fine, a non-compliant building and a problem at the next letting.
The Importance of Sustainability in Commercial Property
Commercial properties are some of the largest consumers of energy and resources. According to the International Energy Agency, buildings account for nearly 30% of global energy consumption and a significant share of greenhouse gas emissions. This impact is encouraging property owners and managers to prioritise eco-friendly practices to minimise their environmental footprint.
Sustainable properties not only attract environmentally conscious tenants but also help landlords and investors save on operational costs. By reducing energy and water consumption, cutting down waste, and using sustainable materials, these properties can command higher rents, attract longer lease agreements, and even qualify for government incentives.
Benefits of Eco-Friendly Commercial Property
Sustainable commercial property offers a range of benefits for owners, tenants, and communities alike. Here are some of the main advantages:
- Reduced Operating Costs: Green buildings typically have lower energy and water costs, often resulting in significant savings over time. Through efficient design and the use of renewable resources, operational expenses can be minimised.
- Increased Property Value: Eco-friendly certifications like BREEAM in the UK have become sought-after designations. Properties with these certifications are highly regarded and generally see an increase in asset value and rental yields.
- Improved Tenant Satisfaction: Today’s businesses are increasingly eco-conscious and prefer buildings that align with their values. Sustainable features not only help attract these tenants but also enhance workplace wellness by improving air quality, natural light, and thermal comfort.
- Regulatory Compliance and Incentives: As governments introduce stricter environmental standards, buildings with eco-friendly features are better positioned to comply with regulations. Some properties may also qualify for tax benefits, grants, or reduced interest rates for green financing.
How to Improve Your Commercial EPC Rating
Start with the recommendation report that came with your EPC. It lists the improvements the assessor thinks would make the biggest difference. Common measures include:
- LED lighting with smart controls: often one of the cheapest, quickest wins
- Heating upgrades: replacing old boilers, or switching to heat pumps
- Heating and lighting controls: timers, zoning and sensors so energy isn’t wasted
- Insulation: roof, walls and pipework
- Windows and doors: better glazing and draught-proofing
- Air conditioning and ventilation: more efficient systems
- Renewables: solar panels where the roof is suitable
A few practical tips:
- Get advice first. An energy assessor can model which measures will lift the rating most for the money, so you don’t overspend.
- Time works around lease events. Empty periods, lease renewals and refurbishments are the easiest times to carry out work.
- Check the lease. It may say who pays for improvements and whether you need the tenant’s consent. Green lease clauses are becoming more common.
- Re-assess afterwards. Get a new EPC so the improved rating is on record.

A Real-World Example
Picture a landlord with a 1990s office building of around 1,200 square metres in Stoke-on-Trent, currently rated D. It meets today’s E minimum comfortably, so nothing needs doing yet.
But at 1,200 square metres, it’s over the proposed 1,000 square metre threshold. If the government’s 2031 plans become law, it would need to reach B, where cost-effective.
The landlord asks an energy assessor to model a plan. Replacing the lighting with LEDs and adding better controls would lift the building to C at modest cost. Swapping the old gas boilers for heat pumps at the next major refurbishment would take it to B.
The main tenant’s lease is up for renewal in 2028. The landlord plans the lighting work during that renewal and the heating work for a planned refurbishment in 2029, well ahead of 2031. The cost is spread out, the disruption is limited and the building stays lettable.

Summary
A commercial EPC rates a building’s energy efficiency from A+ to G, is needed whenever a building is built, sold or let, and lasts ten years. Expect to pay from around £150 for a simple unit to £800 or more for a complex building. The minimum rating for let commercial property is currently E, with fines of up to £150,000 for breaches. In summer 2026, the government dropped plans for a C rating in 2027 and proposed a B rating from 2031 for let buildings over 1,000 square metres, though that isn’t yet law. Larger buildings should start planning improvements now, timed around lease events.

Frequently Asked Questions
How much does a commercial EPC cost?
Typically from around £150 to £250 plus VAT for a small, simple building, rising to £800 or more for large or complex buildings with air conditioning and central plant. The price depends on the floor area, the number of rooms and how complex the heating, cooling and ventilation systems are.
What is the minimum EPC rating to let a commercial property?
In England and Wales, it’s currently E. Landlords can’t grant a new lease, or continue an existing one, on a commercial building rated F or G unless a valid exemption is registered on the PRS Exemptions Register.
Is the minimum commercial EPC rating going up?
Probably, for larger buildings. In summer 2026, the government proposed a minimum of B from 2031 for let commercial buildings over 1,000 square metres, where cost-effective, and dropped the earlier plan for a C rating in 2027. Smaller buildings would stay at E. The change still needs new legislation.
How long is a commercial EPC valid for?
Ten years from the date it’s issued. If you improve the building during that time, it’s often worth getting a new EPC to show the better rating, especially before marketing it for sale or to let.
Who is responsible for getting a commercial EPC?
The seller or landlord. They must make it available free of charge to prospective buyers or tenants, and they’re liable for the penalty if they don’t. Fines for failing to provide one are usually 12.5% of the rateable value, between £500 and £5,000.
