A property must have an EPC before it can be bought, sold or rented unless it is subject to an exemption. Failure to obtain an EPC when required makes you liable for a civil penalty notice. The default penalty for failing to obtain an EPC is 12.5% of the value of the property or £750 where for any reason this formula cannot be applied. Where the formula can be applied, the minimum penalty is £500 and is capped at £5,000. These penalties are enforced by your local authority building control department.  There are also penalties where you obtain an EPC below an E rating and continue to let or sell the property. These penalties will scale in line with the government’s proposed requirements from 2025 and 2028.
