Minimum Energy Efficiency Standards For Commercial Property
As of 2026, the Minimum Energy Efficiency Standards (MEES) for

At Simcott Renewables, based right here in Witham, we are seeing a significant shift in how the Government views energy efficiency in residential property. The latest consultation on Minimum Energy Efficiency Standards (MEES) signals the biggest shake-up for the Private Rented Sector (PRS) in years.
Here is everything you need to know about the proposed changes and how they might affect your properties.
Since 2020, it has been a legal requirement for all privately rented properties to have a minimum Energy Performance Certificate (EPC) rating of E. If your property doesn't hit this mark, you cannot legally let it out.
However, the "goalposts" are moving. The Government is shifting focus away from just the cost of energy and moving toward how well a building actually performs.
The New Roadmap: EPC C by 2030
While previous proposals were paused in 2023, the new consultation has introduced a clear timeline for landlords:
The upcoming 2026 EPC reform will likely replace the old "cost-based" metric with three new pillars:
Perhaps the most significant news for Essex landlords is the proposed increase in the investment cap. Currently, you are expected to spend up to £3,500 to improve a property. The new proposal suggests raising this to £15,000.
While the Government estimates the average cost to reach compliance will be between £6,100 and £6,800, this is still a major jump. There is an ongoing discussion about a "hardship" exemption that might lower this cap to £10,000 for some, but the message is clear: higher standards require higher investment.
Local properties—especially our beautiful Victorian terraces and older mid-century homes—often struggle with "fabric performance." Under the new rules, simply having cheap bills won't be enough; the building itself needs to be efficient.
The "Solar & Heat Pump" Advantage: The consultation highlights that current EPCs often penalize electricity because it's more expensive than gas, even though heat pumps are 3x more efficient. The new 2026 metrics aim to fix this, making renewable installations a much smarter long-term play for compliance.
