Energy certificates are “staggeringly inaccurate” and energy efficiency upgrades make little difference to the climate crisis or energy bills, an investigation by The Sunday Times claims.

An Energy Performance Certificate (EPC) is a document that sets out the assessed energy efficiency and potential CO2 emissions for a property. The property is rated on a scale from A to G with A being excellent and G a disaster.
