In short the answer is NO.
In England and Wales, regulations which are due to come into force on 1 April 2018 will potentially affect the ability to let out properties and the market value (and marketability) of those properties. The regulations will prevent private Landlords from letting either residential or commercial properties with an Energy Performance Asset Rating (EPAR) lower than E (unless they can point to a specific exemption).
The equivalent regulations for buildings in Scotland do not impose a minimum EPC rating requirement but other measures apply that are already in force for commercial properties.
Landlords, investors, developers and lenders should take note of the differences and not assume energy efficiency policies are the same throughout the UK.
Registers can be searched using the property’s postcode so the easiest way to determine whether or not a valid EPC exists for your property is to check online: Non Domestic EPC Register for England and Wales or EPC Register for Scotland.
