What Is the Minimum EPC Rating to Let a Property?

The minimum standard is changing - here's exactly where the line sits today, and where it's moving to.

Quick answer

Today, the minimum EPC rating to legally let a property is E. From 1 October 2030, that rises to C for every tenancy, existing and new. Band C starts at a score of 69 - every point matters, and some properties are held back by assumed defaults that a fresh assessment can correct.

Today's Standard vs the 2030 Standard

Today
Minimum EPC rating: E. Properties rated F or G cannot legally be let without a valid exemption.
From 1 Oct 2030
Minimum EPC rating: C. Applies to all tenancies, existing and new.

How the Score Works

EPC ratings are based on a numerical efficiency score, with band C starting at a score of 69. Every point matters - insulation, heating system, glazing, and factors like air tightness all contribute, and some properties are held back by assumed default values that a fresh, evidence-based assessment can correct.

Missing the standard isn't the end of the story - see our guide to EPC fines and penalties and our full EPC exemptions guide for the options available if C genuinely isn't achievable.
