Unlocking asset value and long-term compliance through performance-led retrofit strategies
What is it?
This integrated approach supports owners and developers of existing buildings in understanding where their assets stand today – and how to improve performance, compliance, and resilience going forward.
At its foundation is the Energy Performance Certificate (EPC) – a legally required rating that indicates a building’s energy efficiency, ranging from A (most efficient) to G (least). While EPCs are widely used, they often reflect theoretical performance rather than actual use.
To address this gap, EPC+ assessments go further. They combine regulatory energy modelling with scenario analysis, exploring how real-world improvements – such as system upgrades, occupancy profiles, and smarter controls – could elevate a building’s performance.
These assessments are closely tied to the Minimum Energy Efficiency Standards (MEES), which now require non-domestic buildings in England and Wales to meet at least an EPC rating of E. This minimum is set to rise to C by 2027 and B by 2030, significantly impacting leasing, investment, and asset management strategies.
To deliver these improvements practically and affordably, a Retrofit Solutions Analysis identifies tailored interventions for each building. Rather than defaulting to costly overhauls, it prioritises fabric improvements, system upgrades, and operational efficiencies that offer the most benefit for compliance, energy savings, and carbon reduction.
Why does it matter?
MEES regulations are no longer future concerns – they’re already reshaping the lettable property landscape. Buildings that fall below required EPC thresholds are becoming increasingly difficult to lease, refinance, or sell without demonstrable improvement plans. Fines and reputational risk for non-compliance are mounting, and regulatory scrutiny is only increasing.
Yet the real challenge isn’t just the legal threshold – it’s the mismatch between modelled energy ratings and actual performance. Many buildings with “compliant” EPC ratings underperform operationally, leading to higher bills, lower comfort, and long-term carbon liabilities. EPC+ assessments help bridge this gap by reflecting how buildings are actually used – not just how they’re modelled at design.
From here, Retrofit Solutions Analysis offers a clear path forward. It considers each building’s specific characteristics – construction type, services, occupancy, usage patterns – and evaluates a range of improvement measures against impact, feasibility, and cost. The focus isn’t just hitting an EPC target, but doing so in a way that meaningfully improves comfort, carbon, and cost.
In Summary
Energy compliance isn’t just a checkbox – it’s a gateway to long-term building performance. A basic EPC may tell you where you stand today, but it won’t tell you how to get where you need to be. That’s where EPC+ and retrofit planning come in.
By combining performance-based modelling with practical upgrade strategies, you can ensure your building is not just compliant, but also efficient, future-proof, and cost-effective in operation.
