According to a report by property consultant Robert Irving Burns, 78% of offices in Westminster and 71% in the City of London are projected to fail the upcoming Minimum Energy Efficiency Standards (MEES) set for the early 2030s. This situation poses a significant risk of these properties becoming stranded assets, as landlords struggle to make necessary upgrades amid labor shortages and financing challenges. Currently, over 12,000 offices in central London need substantial improvements to comply with the new regulations. The report highlights that only 4% of office properties in the City hold the highest Energy Performance Certificate (EPC) rating of 'A', leading to a growing demand for high-performing, energy-efficient buildings. As a result, the market is becoming increasingly polarized, with properties that meet sustainability standards commanding premium rents, while older, non-compliant buildings face lower rents and longer vacancy periods. This trend indicates a looming crisis for landlords who may not meet the EPC deadline, potentially reshaping London's commercial real estate landscape.
