Prince William may be a rogue landlord, it appears.

An investigation by The Mirror newspaper and the Channel 4 Dispatches programme claims that possibly hundreds of Prince William’s tenants are at risk of fuel poverty.

The probe suggests as many as one in seven residences from the Duchy of Cornwall are reported to have Energy Performance Certificate ratings of F or G.

The investigation says Prince William has been vocal about his homelessness campaign and the belief of “everyone having a right to a safe and stable home”. 

But investigators claim multiple tenants from the Prince’s 600 rental property portfolio have provided evidence of poor quality housing and that six homes scored just one point each out of a possible 100 on their EPC.

Since 2020, it’s been against the law for landlords to let properties rated lower than E, according to the Minimum Energy Efficiency Standards regulations, barring a lawful exemption.

The Mirror says that since the implementation of new MEES regulations, Prince William and the former Duke of Cornwall – King Charles – have collectively received £90m in profits from the Duchy.

The Duchy of Cornwall declined to comment to the investigators on energy efficiency ratings but insisted it is a “responsible and compassionate landlord” and added: “We are a responsible Landlord committed to continuous improvement of its properties. We work closely with our tenants to actively address energy efficiency of properties across our portfolio while minimising the impact on residents.

“The Duchy of Cornwall is a private estate with a commercial imperative which we achieve alongside our commitment to restoring the natural environment and generating positive social impact for our communities. Prince William became Duke of Cornwall in September, 2022, and since then has committed to an expansive transformation of the Duchy.

“This includes a significant investment to make the estate net zero by the end of 2032, as well as establishing targeted mental health support for our tenants and working with local partners to help tackle homelessness in Cornwall.”
