What are the different categories of listed buildings?

The classification system puts listed buildings into 3 different ‘grades’, Grade I, Grade II*, and Grade III.

• Grade I buildings are of exceptional interest. Only 2.5% of listed buildings in England are Grade I 
• Grade II* buildings are particularly significant buildings above special interest. Grade II* buildings account for 5.8% of listed buildings in England
• Grade II buildings are of special interest and worthy of preservation. More than 90% of all listed buildings in England are Grade II
