Non-Domestic MEES: How Realistic is the EPC B by 2030 Target for Commercial Properties?

As the UK continues its journey toward net-zero, commercial property owners are facing one of the most significant regulatory shifts in decades: the proposed tightening of Minimum Energy Efficiency Standards (MEES).

Although the current legal requirement, a minimum EPC rating of E to let non-domestic properties has been in place since April 2023, the next step in the Government’s long-term plan remains uncertain.

The proposal to require an EPC B for all let commercial buildings by 2030 is still on the table, but with consultation responses delayed and industry commentary shifting, the big question is:

How realistic is the 2030 target, and what should landlords be doing now?

Where MEES Stands Today

Under existing regulations, non-domestic properties with an EPC rating of F or G cannot be legally let unless the landlord registers a valid exemption. This has already driven significant upgrade activity across England and Wales, especially in older commercial stock.

But this is only the first step.

In the 2020 Energy White Paper and the subsequent 2021 consultation, the Government outlined a clear long-term direction:

• An interim milestone of EPC C around 2027–2028
• A full compliance requirement of EPC B by 2030

This would be a transformational shift, with estimates suggesting that 80% or more of the UK’s commercial buildings would need investment to meet EPC B.

The Delayed Consultation Response: Why This Matters

Here’s where things stand as of November 2025:

• The Government’s response to the non-domestic MEES consultation was originally expected in the first half of 2025.
• That date has passed, and no formal response has been published.
• Industry bodies, including Elmhurst Energy, confirm that the sector is still waiting for clarity on the final policy direction.
• Commentary now suggests that the proposed EPC B deadline may shift, potentially landing somewhere between 2030 and 2035.

For landlords and commercial agents, this uncertainty creates a planning challenge. You know major change is coming, but not precisely when, or how strict the requirements will be.

Why the EPC B Target is Harder Than It Looks

Even if the Government sticks with EPC B by 2030, achieving it across the commercial sector is far from straightforward.

1. Older buildings will need substantial upgrades

Pre-1990 office, retail and industrial buildings often require:

• New HVAC systems
• LED and control system upgrades
• Fabric improvements
• Better insulation and glazing
• Replacement of older gas-based heating systems

2. Costs vary widely

Studies show upgrade costs ranging from £30–£150 per m² for light improvements, up to £300–£500+ per m² for major refurbishments.

3. Supply chain pressure

The closer the deadline, the higher the demand for surveyors, assessors, installers and retrofit specialists, affecting cost and timelines.

4. Valuation and lending risk

Some lenders are already stress-testing portfolios against EPC requirements, which could impact:

• Refinancing
• Loan-to-value assessments
• Investment decisions
• Asset disposals

This means property owners who act early will be better protected against value erosion.

So… How Realistic Is EPC B by 2030?

The honest answer: It’s uncertain.

Based on current industry intelligence:

• The 2030 target might remain, especially for higher-value commercial stock.
• The Government may introduce a staggered approach, with later dates for certain building classes.
• The final policy decision may push EPC B closer to 2032–2035 to reflect market capacity and cost.

But one thing is clear:
The direction of travel is not changing.
Commercial buildings will need to become significantly more energy efficient this decade.

What Commercial Property Owners Should Do Now

Regardless of the final deadline, here’s how you can get ahead:

1. Review your EPC portfolio

Identify:

• Any F or G ratings (currently unlawful to let)
• D and E ratings (highest improvement risk)
• High-consumption assets
• Buildings with upcoming lease events

2. Commission an early EPC or MEES assessment

This gives clarity on:

• Likely improvement measures
• Potential costs
• Modelled EPC outcomes
• Payback and savings

3. Focus on cost-effective “quick wins”

• LED lighting
• Controls and zoning
• Draught-proofing
• Insulation upgrades
• Smart building management systems
• Replacement of old heating controls
  These can often move a rating 1–2 bands with minimal investment.

4. Build a long-term compliance plan

Even with shifting timelines, a structured plan ensures you’re not caught off guard.

5. Budget ahead for bigger upgrades

Spreading investment over multiple years is often easier than facing a single large cost at the point of non-compliance.

The Bottom Line: Uncertainty Doesn’t Mean Inaction

The Government may adjust the MEES timeline, but the shift toward higher-performing commercial buildings is certain.

By planning early, landlords and property managers can:

• Reduce compliance risk
• Avoid future letting restrictions
• Protect asset value
• Improve building comfort and efficiency
• Spread costs more effectively
• Strengthen lender and tenant confidence
