Grade I, Grade II* and Grade II: What the Difference Means for Lending
Listed buildings in England are classified into three grades. Grade II is the most common, covering around 91% of all listed buildings. These are considered nationally important and of special interest, warranting every effort to preserve them. Grade II* (pronounced Grade Two Star) covers approximately 6% of listings and represents particularly important buildings. Grade I covers the remaining 3% — these are of exceptional interest and are the most strictly protected.
For lending purposes, the grade of listing matters significantly. Grade II properties are the most widely accepted by lenders, as they are relatively common and the restrictions, while meaningful, are manageable for owners who understand them. Grade II* and Grade I properties are accepted by a much smaller number of lenders due to the greater complexity of their protection status, the specialist insurance required and the difficulty of carrying out repairs in the event of damage.
Conservation area designation is a separate but related consideration. A building does not need to be individually listed to be in a conservation area, and conservation area restrictions on alterations can affect lender appetite even for unlisted properties within those boundaries.
Listed Building Consent and Alteration Restrictions
Any alteration to a listed building that affects its character as a building of special architectural or historic interest requires Listed Building Consent from the local planning authority. This applies to both external and internal changes, including alterations to features such as original fireplaces, windows, staircases, panelling and structural elements. Undertaking unauthorised works to a listed building is a criminal offence.
Lenders are alert to the risk that previous owners may have carried out unauthorised alterations, which can create liability for the current owner and make the property difficult to sell or insure. When assessing an application, lenders will instruct a valuer to check for any obvious signs of unauthorised works, and where concerns are identified, they may require retrospective consent or indemnity insurance as a condition of lending.
The ongoing cost of maintaining a listed building to the standard required by Historic England — using approved materials and methods — is also higher than for standard properties. Lenders factor this into their assessment of affordability and residual property risk.
