Impact of Regulatory Changes on Commercial Property De-Rating

In recent years, the commercial property sector in the UK has been undergoing a steady transformation — driven largely by evolving environmental and regulatory frameworks. From EPC (Energy Performance Certificate) reforms to new sustainability targets, property owners and tenants alike are navigating a landscape that increasingly prioritises energy efficiency and compliance.

At the heart of these changes lies the concept of commercial property de-rating — a process that can help businesses manage costs and remain compliant when regulatory shifts affect property usability or market value.

Understanding Commercial Property De-Rating

De-rating refers to the reduction of a property’s rateable value — essentially lowering the amount of business rates payable to local authorities. It’s often relevant when a property becomes partially unusable or less valuable due to refurbishment, strip-out works, or regulatory restrictions.

With the introduction of more stringent MEES (Minimum Energy Efficiency Standards) and EPC requirements, de-rating has become an essential strategy for landlords and occupiers during property transitions.

From April 2023, commercial buildings with an EPC rating below ‘E’ cannot be legally leased in England and Wales. Looking ahead, government plans suggest that by 2030, most commercial spaces may need to achieve a minimum EPC rating of ‘B’ — a significant jump that will impact both older and newer buildings.

How Regulatory Changes Influence De-Rating

1. EPC and MEES Reforms

The tightening of EPC thresholds directly influences property values. Buildings that fail to meet new standards may face void periods, higher renovation costs, or difficulty attracting tenants. Landlords planning refurbishment or strip-out works can apply for temporary de-rating if parts of the property are unusable during improvement projects.

2. Sustainability and Net Zero Targets

The UK’s commitment to net zero by 2050 has accelerated policy shifts in construction and property management. Sustainable retrofits — such as improving insulation, upgrading HVAC systems, and installing LED lighting — are no longer just optional but essential to remain compliant. However, during these improvement periods, rate relief or de-rating applications can mitigate financial pressures.

3. Changes in Occupancy and Use

When a property’s use changes due to new regulations or evolving market conditions (e.g., conversion from office to mixed-use space), it may qualify for a re-assessment of its rateable value. This process ensures the property’s taxation accurately reflects its usability and current condition.

What Property Owners Should Do Now

1. Conduct EPC and Compliance Audits Review your property’s current EPC rating and assess which areas require upgrades.

2. Plan for Sustainable Refurbishment Partner with professionals experienced in strip-out and dilapidation works, such as Stripout London, to ensure all refurbishments meet upcoming energy standards.

3. Consult with Rating Specialists A qualified surveyor or rating consultant can help identify opportunities for de-rating during void or refurbishment periods.

4. Stay Informed on Legislative Changes Regulations evolve quickly — keeping ahead of updates from the Department for Energy Security and Net Zero (DESNZ) and RICS will prevent costly surprises.
