Two million rental properties.
One deadline.
By October 2030, all privately rented homes must reach EPC Band C. This site — and the book behind it — explains how ratings are built, what actually moves them, and how to make the right decision for every property in your portfolio.
Why age is the starting point
The older the property, the lower the typical EPC rating. Most pre-1930 housing sits at Band E or below. Most post-2012 housing comfortably clears Band C. The compliance problem is concentrated in the middle of the century — cavity-wall terraces and semis built before insulation standards existed.
