Royal Estates Rent Out Homes with F/G Energy Ratings

More than 100 homes on the inherited estates of King Charles and Prince William have been found to fall below the legal minimum energy performance standards for landlords, a Guardian investigation has revealed. The analysis focused on domestic let properties within the Duchies of Lancaster and Cornwall, as well as the Sandringham estate, and identified that one in five of these dwellings carry Energy Performance Certificate (EPC) ratings of F or G.

The report highlights that these low ratings indicate poor insulation and inefficient heating systems, which contravene the UK's energy efficiency requirements for rental properties. The findings suggest that a significant portion of the royal estates’ rental stock may need substantial upgrades to meet current regulations, raising questions about the management of inherited assets and the obligations of estate owners to provide energy‑efficient housing.

The Guardian’s disclosure underscores the broader issue of energy performance across the UK’s rental market, particularly within historic and high‑profile properties. While the estates are owned by the Crown, the findings point to a need for remedial action to bring all let homes up to the statutory EPC threshold and to improve living conditions for tenants.
