MEES Compliance & EPC Improvement

The Minimum Energy Efficiency Standards (MEES) regulations set the minimum Energy Performance Certificate (EPC) rating required to let commercial property in England and Wales. If your property doesn’t meet the minimum standard, you cannot legally:

• Grant a new lease
• Renew an existing lease
• Continue an existing lease (since April 2023)

This isn’t a future concern — it’s current law with real enforcement and significant penalties. If you’re unsure where a building stands, get an early steer — the cheapest fixes are the ones planned ahead.

The regulations changed in June 2026. Where things stand now:

• EPC E — the minimum to let, now. In force since April 2023 for all lettings, including existing leases. F and G rated properties are already in breach unless a valid exemption is registered.
• EPC B from 2031 — for larger buildings only. Privately rented commercial buildings over 1,000 m² will need to reach EPC B from 2031, where it is cost-effective.
• The proposed EPC C by 2027 has been dropped. That interim milestone is no longer going ahead.
• Buildings of 1,000 m² or under stay on EPC E, with no further deadline announced.

These changes are not yet law — they require secondary legislation. Even so, the time to plan is now: for a larger building well short of B, or any building at F or G today, getting ahead avoids rushed, expensive work when contractors are busy.

Legal compliance

You cannot legally let a non-compliant property. This isn’t optional or advisory — it’s the law.

Enforcement and penalties

Penalties for breaches include:

• Fines of up to £150,000 per property
• Publication on a public register (reputational damage)
• Enforcement notices requiring compliance

Local authorities are the enforcement body, and enforcement activity is increasing.

Lettability

Beyond legal compliance, tenants increasingly consider energy costs and sustainability. A poor EPC rating affects marketability, tenant quality, and achievable rent.

Asset value

Properties with poor energy performance are increasingly discounted in valuations. Investors and lenders scrutinise EPC ratings. Non-compliance affects not just income but capital value.

Future-proofing

The trajectory is clear — standards will keep tightening. Addressing energy performance now avoids rushed, expensive work later when everyone is competing for contractors before deadlines.

Landlords with properties rated E, F, or G

If your property is currently rated E, you’re legal today but won’t be when standards rise. If it’s F or G, you’re already non-compliant unless you have a registered exemption.

Landlords with buildings over 1,000 m²

Properties rated D or below need to plan for the tightening standards. Understanding what’s needed — and budgeting for it — should happen now.

Property owners approaching lease events

If you’re granting a new lease, renewing, or have a break clause approaching, MEES compliance needs to be confirmed or achieved before the event.

Investors acquiring properties

Poor EPC ratings should factor into acquisition pricing. Understanding improvement costs before you buy prevents surprises after.

Anyone facing enforcement

If you’ve received (or expect) enforcement action, you need to achieve compliance or register a valid exemption.

We’ve partnered with specialist energy assessors, to provide a complete MEES compliance service. They handle the energy assessment; we handle the building works.

Step 1: Energy assessment

The energy assessors review your property and model what improvements would achieve the required EPC rating. They don’t just tell you the current position — they identify the specific measures that will move you up the EPC scale, with costs and payback analysis for each option.

Step 2: Works specification

Based on the assessment recommendations, we specify the improvement works required. This might include:

• Insulation upgrades (walls, roof, floor)
• Heating system improvements or replacement
• Lighting upgrades (LED, controls)
• Glazing improvements
• Building management systems
• Renewable energy installations

We prepare detailed specifications suitable for contractor pricing.

Step 3: Procurement and contract administration

We manage the tender process, evaluate contractor submissions, and recommend appointment. Then we administer the works contract — site inspections, payment certification, quality control, completion — ensuring the improvements are delivered to specification, on budget, and on programme.

Step 4: Re-assessment and certification

Once works are complete, the energy assessors re-assess the property and issue the new EPC certificate, confirming you’ve achieved the required rating.

Not every property can achieve the required rating cost-effectively. The regulations include exemptions for specific circumstances:

7-year payback exemption

If improvements that would achieve compliance wouldn’t pay back within 7 years through energy savings, you may be able to register an exemption.

Consent exemptions

If you can’t get necessary consents — planning permission, listed building consent, tenant consent for works — an exemption may apply.

Devaluation exemption

If improvements would reduce the property’s value by more than 5%, you may qualify for an exemption.

New landlord exemption

Newly-acquired properties have a temporary exemption period.

Important: Exemptions must be registered on the PRS Exemptions Register. They last 5 years, are personal to the landlord, and don’t transfer on sale. An exemption isn’t a permanent solution — it’s a temporary measure while you plan proper compliance.

We can assist in establishing whether an exemption might apply to your situation and, if so, help you register it properly.

Financial penalties

• Letting in breach for less than 3 months — the greater of £5,000 or 10% of rateable value, up to £50,000
• Letting in breach for 3 months or more — the greater of £10,000 or 20% of rateable value, up to £150,000
• Providing false or misleading information — up to £5,000

These are per-property penalties. A portfolio of non-compliant properties multiplies the exposure.

Reputational damage

Breach details are published on a public register for at least 12 months. This is visible to tenants, investors, and the market.

Unlettable property

Beyond penalties, you simply cannot let a non-compliant property. Voids, lost income, and stranded assets are the practical consequence.

The properties most at risk are larger buildings (over 1,000 m²) rated below B — legal today, but facing the 2031 standard — plus anything at F or G, which is non-compliant right now. If this describes your portfolio, consider:

Assessment now

Understand what each property needs to clear the E minimum today, and — for anything over 1,000 m² — to reach EPC B by 2031. This informs budgeting and capital planning.

Phased improvement

You don’t have to do everything at once. A phased programme can spread costs and coordinate with other works (refurbishments, lease events, maintenance cycles).

Natural opportunities

Lease ends, refurbishments, and major maintenance are natural points to incorporate energy improvements. Planning ahead lets you capture these opportunities.

Funding and incentives

Energy improvements may qualify for incentives, and energy cost savings can offset capital expenditure. The assessment should include payback analysis.
