How many can actually reach C?

3,084 of the 3,338 sub-C rentals in Chelmsford, 92% of them, already have a potential rating of C or better on their current certificate. That is the assessor's own estimate of what the property would reach if the recommended measures were installed.

Landlords are required to spend up to £10,000 per property. Above that, an exemption may apply.

The transitional rule

An EPC rated C or higher on the existing Energy Efficiency Rating, issued before 1 October 2029, counts as compliant until that certificate expires.
