Certificate of Immunity
Confirmed not listed for five years
A Certificate of Immunity from listing confirms that a building will not be listed for five years. In England the relevant Secretary of State issues it, advised by Historic England. It also blocks a Building Preservation Notice, the council's temporary listing power, for the same term. Wales, Scotland and Northern Ireland each run an equivalent certificate.
What This Means
For the certificate's term you are free of listed building consent, the strictest control on altering a home. Windows, internal layout and demolition are governed by ordinary planning rules instead. Everything else still applies, including permitted development limits, conservation area controls and tree protection. The certificate does not stop the building being brought into a conservation area or scheduled as a monument. The freedom from listing ends when the certificate expires, and the building can then be assessed again. This does not normally affect mortgage approval, buildings insurance or resale.
Practical Advice
- Ask your conveyancer to confirm the certificate's issue and expiry dates in the local authority search.
- Ask the local planning authority whether a conservation area covers the building, because the certificate does not lift those controls.
- Time major works such as a large extension or partial demolition to fall inside the certificate's term.
- Ask Historic England for the advice report behind the certificate to see why the building did not merit listing.
Additional Information
Every UK nation has a version. Welsh Ministers issue certificates of immunity, advised by Cadw. Scotland's equivalent is a certificate of intention not to list, from Historic Environment Scotland. In Northern Ireland the Department for Communities issues one, after consulting the Historic Buildings Council and the district council. The link below sets out the English process only.
