What the grade means for works

Grade I buildings are of exceptional interest — only about 2.5% of listed buildings in England. Any application for listed building consent is notified to Historic England, and alterations are scrutinised closely.

The protection covers the whole building, inside and out, plus fixtures and attached structures. Typical works that need consent: replacing windows or doors, removing walls or historic fabric, changing roof coverings, installing solar panels or external insulation, and adding extensions.
