The clock is ticking. Right now, commercial property owners across the UK face penalties of up to £150,000 for non-compliance with Energy Performance Certificate requirements and with Band C mandatory by April 2027 and Band B by 2030, the window for action is rapidly closing.

This comprehensive guide explains exactly what the 2025 commercial property EPC requirements mean for your business, the steps you need to take to achieve compliance, and the upgrade pathways available to future-proof your property investment.

What Are Commercial Property EPC Requirements?

Energy Performance Certificates (EPCs) are mandatory assessments that rate the energy efficiency of commercial buildings on a scale from A (most efficient) to G (least efficient). Every commercial property in the UK must have a valid EPC when built, sold or rented.

The certificate provides two key ratings:

• Current Energy Efficiency Rating: Your property's existing performance based on actual energy use for heating, hot water, lighting and ventilation

• Potential Energy Efficiency Rating: What your property could achieve with recommended improvements

Commercial EPCs are valid for 10 years and must be made available to prospective tenants or buyers. However, having a certificate is only the first step, your property must also meet Minimum Energy Efficiency Standards (MEES) to be legally let.

Who Needs a Commercial EPC?

Commercial EPCs are required for:

• Offices and commercial workspaces

• Retail units and shopping centres

• Hotels, pubs and restaurants

• Schools, colleges, and educational facilities

• Hospitals and healthcare buildings

• Warehouses and industrial units

• Leisure centres and sports facilities

• Any building where people work or visit

The only exceptions are buildings used primarily for worship, temporary structures with a planned use of less than two years, and standalone buildings with total floor space under 50 square metres.

The April 2025 Deadline: What You Need to Know

Critical Date: 1 April 2025

From this date, all new tenancy agreements and lease renewals for commercial properties must meet a minimum EPC rating of Band E. This applies to existing regulations under the Minimum Energy Efficiency Standards (MEES).

However, the 2025 deadline is more nuanced than many property owners realise:

What Changes in April 2025?

While the minimum Band E requirement has been in force since 2018 for new tenancies and since 2023 for existing tenancies, April 2025 marks an important enforcement milestone where non-compliant properties face intensified scrutiny and stricter penalties.

More significantly, April 2025 serves as a crucial warning point: you have just two years until the Band C requirement takes effect in April 2027.

Why Act Now?

Most commercial property owners are discovering that upgrading from Band E, F or G to Band C requires substantial work that cannot be completed overnight. The average upgrade project timeline is:

• Assessment and planning: 4-8 weeks

• Funding applications: 8-12 weeks

• Procurement and scheduling: 6-12 weeks

• Installation and commissioning: 4-16 weeks (depending on scope)

This means properties starting their upgrade journey now may only just achieve Band C compliance by the April 2027 deadline.

If you're currently managing a commercial property portfolio and haven't assessed your EPC compliance status, the time to act is now not April 2025 and certainly not April 2027.

Understanding MEES Regulations

The Minimum Energy Efficiency Standards (MEES) are regulations that prohibit landlords from letting commercial and residential properties that fall below a minimum energy efficiency rating.

Current MEES Requirements

Since 1 April 2023, it has been illegal to continue letting a commercial property with an EPC rating below Band E, even on an existing tenancy. This applies to:

• New tenancy agreements

• Tenancy renewals

• Continuing tenancies (since April 2023)

Key MEES Rules You Must Know

1. The Compliance Obligation Falls on Landlords

Property owners and landlords are responsible for ensuring their buildings meet MEES before granting or continuing a tenancy. Tenants cannot be contractually required to fund improvements, though they may choose to do so.

2. Exemptions Are Temporary and Limited

Some properties may qualify for temporary exemptions lasting up to five years, including:

• 7-year payback exemption: If the cost of all recommended improvements exceeds a seven-year payback period

• Consent exemptions: Where required consents (planning permission, listed building consent, etc.) cannot be obtained

• Devaluation exemption: If improvements would reduce the property value by more than 5%

• Third-party exemption: Where a third party (freeholder, mortgage lender) refuses consent

Importantly, exemptions must be formally registered on the national PRS Exemptions Register **before** a property is let. They are not automatic.

3. The £3,500 Per Property Cap Has Been Removed**

Previously, landlords were only required to fund improvements up to £3,500 per property. This cap no longer applies to properties below Band E, meaning landlords must now fund all cost-effective improvements necessary to reach Band E, regardless of cost.

4. MEES Applies to All Commercial Tenancy Types**

The regulations cover:

• Standard commercial leases

• Licences to occupy

• Tenancies at will

• Short-term lets

Even temporary commercial arrangements fall under MEES if they meet the legal definition of a tenancy.

Financial Penalties for Non-Compliance

The financial consequences of failing to meet commercial property EPC requirements are severe and escalating.

Current Penalty Structure

Local authorities can impose civil penalties for MEES breaches:

Maximum penalty per property: £150,000

The penalty is calculated based on the rateable value of the property and the length of non-compliance.

How Penalties Are Calculated

For properties let in breach of MEES:

• Properties with rateable value under £50,000: 10% of rateable value (minimum £5,000, maximum £10,000)

• Properties with rateable value £50,000 or above: 20% of rateable value (minimum £10,000, maximum £150,000)

These penalties apply per property, per breach. A landlord with multiple non-compliant properties faces multiple fines.

Beyond Financial Penalties

Non-compliance also brings:

• Reputational damage: Breach details are published on a public register

• Lease complications: Inability to grant new tenancies or renewals

• Diminished property value: Non-compliant properties are worth significantly less

• Insurance issues: Some commercial property insurers are beginning to factor EPC ratings into coverage decisions

• Tenant litigation risk: Tenants may pursue legal remedies for non-compliant properties

Enforcement Is Increasing

While enforcement was initially light-touch, local authorities across the UK are now actively investigating MEES compliance, particularly in high-value commercial areas. Trading Standards officers can:

• Request evidence of EPC compliance

• Inspect properties

• Issue compliance notices

• Impose financial penalties without court proceedings

Future Requirements: Band C (2027) and Band B (2030)

The current Band E minimum is only the beginning of a progressive tightening of commercial energy efficiency standards.

April 2027: Band C Becomes Mandatory

From 1 April 2027, all commercially let properties must achieve a minimum EPC rating of Band C. This applies to:

• All new tenancy agreements from April 2027

• All tenancy renewals from April 2027

• All continuing tenancies from April 2027

This represents a significant leap in energy efficiency requirements. Government data shows:

• Approximately 60% of commercial properties currently fall below Band C

• Upgrading from Band E to Band C typically requires investment of £15,000 to £80,000 depending on property size and current condition

• The average improvement involves multiple systems: heating, lighting, insulation, and building management

April 2030: Band B Target

Current proposals suggest a further increase to Band B by 2030, though this remains subject to government consultation and final confirmation.

What This Means for Property Owners

Progressive Investment Strategy Required

Rather than treating compliance as a one-time upgrade, forward-thinking property owners are adopting a phased improvement approach:

Phase 1 (2024-2025): Achieve Band E compliance, focus on quick wins (LED lighting, heating controls, insulation)

Phase 2 (2025-2027): Progress toward Band C through more substantial upgrades (HVAC replacement, renewable energy, advanced building management systems)

Phase 3 (2027-2030): Optimisation and preparation for Band B requirements

This staged approach spreads costs, allows technology to mature, and positions properties to take advantage of emerging grant funding.

The Commercial Advantage of Early Compliance

Properties achieving Band C or higher ahead of the 2027 deadline benefit from:

• Higher rental values: Research shows Band C properties command a premium of 5-10% over Band D/E equivalents

• Improved tenant retention: Occupiers increasingly prioritise energy-efficient premises

• Future-proofing: Avoiding the 2027 compliance rush when contractors will be in high demand

• Grant eligibility: Current funding schemes prioritise early adopters

• Enhanced corporate reputation: Demonstrating environmental leadership appeals to ESG-conscious tenants

How to Check Your Property's Current EPC Rating

Before planning any upgrades, you need to understand your property's current energy performance.

Finding Your Existing EPC

Option 1: EPC Register Search

Visit the official UK Government EPC register at www.epcregister.com and search by:

• Full property postcode

• Building address

• EPC certificate number (if known)

The register is publicly accessible and free to use. You can download the full EPC certificate including the detailed recommendation report.

Option 2: Request from Your Letting Agent or Previous Owner

If you've recently acquired the property, the EPC should have been provided during the transaction. Check your property purchase or lease documentation.

Understanding Your EPC Certificate

Your EPC contains valuable information:

1. Energy Efficiency Rating (Current)

The main rating band (A-G) and numerical score (1-100+) showing current performance.

2. Environmental Impact Rating

A CO2 emissions rating, also scored A-G, showing the property's environmental performance.

3. Energy Use Per Square Metre

Measured in kWh/m²/year, this allows comparison with similar buildings.

4. Recommendation Report

Crucially, this section lists:

• Recommended improvements to reach higher bands

• Estimated costs for each improvement

• Typical annual savings from each measure

• Potential rating after implementing improvements

5. Validity Date

EPCs last 10 years. If yours is nearing expiry, you'll need a new assessment, an ideal opportunity to incorporate improvements before re-assessment.

When You Need a New EPC

A new EPC is required when:

• Your current certificate has expired (after 10 years)

• You've made significant building alterations

• You've completed energy efficiency improvements and want the higher rating recognised

• You're selling or letting the property and don't have a valid certificate

What If Your Property Doesn't Have an EPC?

Properties without a valid EPC cannot be legally marketed for sale or let. You must commission an EPC from an accredited Domestic Energy Assessor (for residential) or a qualified Commercial Energy Assessor before proceeding with any transaction.

Upgrade Pathways to Achieve Compliance

Moving from Band E, F or G to Band C requires a strategic approach. The most cost-effective pathway depends on your property's current condition and your long-term plans.

Step 1: Comprehensive Energy Audit

Before investing in improvements, commission a detailed energy audit that goes beyond the basic EPC assessment. This should include:

• Thermal imaging to identify heat loss

• Assessment of current HVAC system efficiency

• Lighting audit and lux level measurements

• Building fabric inspection (insulation, glazing, air tightness)

• Review of heating and hot water systems

• Analysis of building management and control systems

A thorough audit prevents wasted investment in measures that deliver minimal rating improvement.

Step 2: Prioritise High-Impact, Low-Cost Measures

The EPC recommendation report categorises improvements by cost-effectiveness. Focus first on measures offering the best return:

• LED lighting replacement across all areas

• Heating system controls and thermostatic radiator valves (TRVs)

• Loft and cavity wall insulation (where applicable)

• Draught-proofing and air tightness improvements

• Hot water tank insulation

These measures often deliver immediate energy savings while improving your EPC band.

Step 3: Address Building Fabric

Before upgrading energy systems, improve the building envelope:

• External or internal wall insulation

• Roof insulation upgrades

• Secondary glazing or window replacement

• Air source heat pump readiness preparation

• Improved ventilation with heat recovery

A well-insulated building reduces heating demand, allowing smaller, more efficient systems.

Step 4: Upgrade Major Systems

With fabric improvements complete, replace outdated energy systems:

• High-efficiency boiler replacement or heat pump installation

• Variable refrigerant flow (VRF) air conditioning systems

• LED lighting with daylight and occupancy sensors

• Building Energy Management System (BEMS)

• Solar photovoltaic (PV) panels

• Battery storage systems

These upgrades often push properties from Band D/E into Band C or higher.

Step 5: Optimisation and Verification

After installation:

• Commission a new EPC to verify rating improvement

• Monitor actual energy consumption against projections

• Fine-tune controls and settings for optimal performance

• Train facilities staff on new system operation

Barry Turner & Son is an approved Boiler Upgrade Scheme installer and Gas Safe registered, enabling us to manage your entire heat pump grant application and installation with full compliance guarantees.

Available Grants and Funding Support

Several funding schemes can offset the cost of commercial energy efficiency improvements:

1. Boiler Upgrade Scheme (BUS)

• Grant Amount: £7,500 for air source heat pumps or ground source heat pumps

• Eligibility: Commercial and residential properties in England and Wales

• Application: Via approved installers

The BUS grant makes heat pump installation financially viable for many commercial properties. Barry Turner & Son is an approved installer and can manage your entire BUS application and installation process.

2. Enhanced Capital Allowances (ECAs)

• Tax Benefit: 100% first-year capital allowance on qualifying energy-saving equipment

• Eligibility: Businesses paying UK corporation tax or income tax

• Qualifying Technologies: Energy-efficient lighting, HVAC systems, motors, and other equipment listed on the Energy Technology List

ECAs allow businesses to deduct the full cost of qualifying equipment from taxable profits in the year of purchase, providing immediate cash flow benefits.

3. Local Authority Energy Efficiency Schemes

Many local authorities operate grant programmes for commercial property energy improvements:

• Greater London Authority (GLA) schemes for London businesses

• Warmer Homes grants (some include commercial elements)

• Business Energy Efficiency Programme (BEEP) in various regions

Contact your local authority's environmental or business support team to explore available funding.

4. Green Finance Options

Several lenders offer preferential finance for energy efficiency projects:

• Green loans with reduced interest rates for EPC improvement projects

• Property Assessed Clean Energy (PACE) financing (emerging in UK)

• Energy Performance Contracts where savings fund the improvements

5. Renewable Heat Incentive (RHI)

Note: The non-domestic RHI closed to new applications in March 2022, but existing recipients continue receiving payments for 20 years. While no longer available for new projects, it demonstrates the government's ongoing commitment to renewable heat, expect future schemes.
