Commercial EPC rules are tightening: what Facilities Managers, Finance Directors and landlords should do now
Updated: Jul 28
The goalposts have moved — and the clock is already running
The government has confirmed the direction of travel for Minimum Energy Efficiency Standards (MEES) in commercial property. From April 2027, the minimum EPC rises to C. From 2031, commercial buildings over 1,000 m² must reach EPC B to be legally let.
If you manage a portfolio with D or E ratings, this isn’t a ‘future problem’. It’s a programme of work that needs to start now — because lead times, costs and contractor capacity won’t stay in your favour.
A non-compliant building can’t be legally let — that’s lost income until the issue is fixed.
Why this matters for Facilities, Finance and landlords
Facilities Managers: you’ll be asked for a plan, evidence, and measurable improvements — not just ‘we’re looking into it’.
Finance Directors: EPC compliance is becoming a cashflow and risk issue (voids, capex timing, and tenant churn).
Commercial landlords: EPC performance is increasingly tied to lettability, valuation, and exit strategy.
What actually improves an EPC rating
EPC ratings improve when a building needs less energy to operate and/or when the energy it uses is cleaner. In practice, that usually means a combination of demand reduction and smarter plant control.
For many commercial buildings, HVAC is the biggest lever — and controls are often the fastest route to measurable improvement without ripping out working equipment.
High-impact measures we see most often
Optimising HVAC controls (time schedules, setpoints, zoning, demand-led ventilation, heat recovery control)
Upgrading legacy BMS / controls to modern, energy-optimised strategies
Plant sequencing and boiler/chiller optimisation
Metering, monitoring and fault detection to stop energy drift
Lighting upgrades and controls (where relevant)
On-site generation (e.g., solar) where the building and roof allow
The ‘capital problem’ — and how to de-risk it
Many portfolios stall because the compliance pathway looks like a major capex programme. The reality is you can often stage the work: start with low-disruption, high-return measures (controls optimisation and monitoring), then plan larger upgrades with better data and a clearer business case.
For Finance teams, the key is turning EPC compliance into a managed investment plan — with prioritisation by risk (rating, lease events, asset strategy) and by payback.
Why ‘2031’ is closer than it looks
Even straightforward projects take time once you include surveys, design, procurement, installation, commissioning and verification. As deadlines approach, assessor availability and contractor capacity will tighten — and costs typically rise with demand.
A practical next step: get a controls-led EPC readiness assessment
If you’re unsure where to start, begin with a site-by-site assessment focused on HVAC controls and building operation. It should answer:
What’s the current EPC rating and what’s driving it?
Which measures will move the rating fastest?
What can be done with minimal disruption to tenants?
What’s the expected energy and cost impact — and how will it be evidenced?
What’s the timeline to reach EPC C by 2027 and EPC B by 2031?
