Phased Retrofit Strategies for Commercial Property: Preparing for Proposed MEES Changes Without Overspending

As the commercial property sector prepares for the Government’s proposed EPC B requirements for larger rented buildings from 2031, many landlords are asking the same question: “When should we start investing in energy efficiency improvements?”

One of the biggest mistakes commercial property owners make is either investing too early or waiting too long. The reality is that timing can be just as important as the improvements themselves. The most successful landlords and asset managers are not necessarily spending more than their competitors. They are simply investing at the right time.

A phased retrofit strategy allows property owners to improve EPC performance, reduce future compliance risk and protect asset value whilst maintaining control over capital expenditure.

Why timing matters

With the Government proposing that privately rented non-domestic buildings over 1,000m² in England and Wales should reach EPC B from 2031, where cost-effective, many landlords are reviewing their portfolios and identifying future investment requirements. However, delivering every improvement immediately is rarely the most efficient approach. Likewise, delaying decisions until the end of the decade can create unnecessary risk, higher costs and limited flexibility.

Scotland and Northern Ireland sit outside this. Neither has a minimum EPC band in force for commercial property, so if your portfolio spans more than one nation the phasing will not be the same everywhere.

A phased strategy provides a more practical route to preparing for future requirements.

Phase 1: quick wins and immediate improvements, now to 2027

The first phase should focus on low-cost, high-impact measures that can deliver immediate energy savings and potentially improve EPC performance. Examples include:

• LED lighting upgrades
• Controls optimisation
• Building recommissioning
• Air tightness improvements
• Operational efficiency measures

These interventions may help improve lower-rated assets without significant capital expenditure. Our guide to the best return on investment energy efficiency improvements looks at which of these tend to pay back fastest.

Importantly, the previously proposed 2027 EPC C milestone is not being taken forward by Government. This does not mean 2027 should be ignored. It provides a useful planning horizon for identifying opportunities, gathering information and beginning a structured improvement programme rather than waiting for future requirements to become urgent.

Phase 2: strategic planning for EPC B, 2027 to 2030

Once the initial opportunities have been identified, landlords can focus on preparing for the longer-term proposed EPC B requirement. This phase may include:

• EPC modelling
• Portfolio-wide capital planning
• Building electrification assessments
• Targeted plant upgrades
• Decarbonisation roadmaps

Importantly, these improvements can be aligned with lease events, refurbishment programmes and planned maintenance cycles, reducing both cost and disruption. Planning ahead also gives property owners time to assess different options rather than committing to the first available solution.

Phase 3: major interventions where required, 2030 onwards

Some buildings may require more substantial interventions to achieve EPC B, should the proposed requirement become law, or to support wider Net Zero objectives. These may include:

• Major HVAC replacement
• Fabric improvements
• Heat pump installation
• Electrical infrastructure upgrades

By identifying these requirements early, landlords can plan major works strategically, maximise the life of existing assets and avoid unnecessary reactive expenditure.

The benefits of a phased approach

A phased retrofit strategy offers several advantages:

• Spreads capital expenditure over time
• Aligns improvements with lease cycles
• Reduces tenant disruption
• Improves budget forecasting
• Supports long-term asset value

Most importantly, it allows property owners to make informed investment decisions rather than reacting under pressure.

Do not ignore smaller commercial buildings

The Government’s current proposed EPC B requirement focuses on privately rented non-domestic buildings over 1,000m² in England and Wales. For smaller buildings, the current stated intention is for the existing EPC E minimum to continue. However, landlords should avoid interpreting this as a permanent exemption from future energy performance requirements. The regulatory landscape is continuing to evolve and there is no guarantee that future MEES requirements will always apply the same size threshold.

The direction of travel across the property sector is clear. Energy efficiency, carbon performance and sustainability credentials are becoming increasingly important to occupiers, investors and lenders regardless of building size.

Forward-thinking landlords are therefore assessing entire portfolios rather than focusing solely on buildings currently affected by proposed regulations. Preparing early provides greater flexibility, more time to plan and the opportunity to spread investment over time.

How Vital Direct can help

At Vital Direct, we help commercial property owners, landlords and asset managers develop cost-effective pathways towards improved EPC ratings, all-electric operation and Net Zero in Operation objectives. Our EPC Plus advisory reports help clients understand what improvements may be needed, when they should be considered and how to maximise return on investment across individual assets and entire portfolios.

With the Government’s proposed MEES changes on the horizon, success is not simply about deciding what to do. It is about deciding when to do it.
