If a property is newly built or has been completely rewired, it should have an Electrical Installation Certificate known as an EIC.
Landlords can provide a copy of the EIC to tenants and, if requested, the local authority. The landlord will then not be required to carry out further checks or provide a report for 5 years after the EIC has been issued, as long as they have complied with their duty or duties under the Regulations.

That is the guidance, I am not sure how it squares up with the actual legal document as written.
The letting agent needs to get a grip.
