While the general rule is that listed building consent is required for any works affecting the character of a listed building, there is an important category of work that does not require consent: genuine like-for-like maintenance that preserves the existing character without changing it.

Routine Maintenance

Routine maintenance that replaces like with like, in the same material and method as the element being maintained, does not require listed building consent. Repainting in the same colour using the same type of paint, repointing using the same lime mortar mix and profile that was previously used, replacing broken tiles or slates with matching tiles or slates from the same source, and repairing failed plaster using the same lime plaster mix and technique as the original are all maintenance activities that preserve the existing character and do not require consent.

The key tests are whether the material is genuinely like-for-like, whether the method is the same, and whether the result preserves the existing character without altering it. Replacing lime render with modern sand-cement render, even if described as maintenance, is an alteration in material and technique that affects the character and requires consent.

Internal Works with No Character Impact

Internal works that genuinely have no impact on the character of the listed building do not require consent. Decorating with conventional paint on surfaces that have been previously painted does not require consent. Replacing like-for-like internal fittings that are not themselves of special interest, such as replacing a modern kitchen fitted in the 1990s with another modern kitchen, may not require consent if the fabric of the original building is not affected. However, any work that removes or alters original historic fabric, even internally, is likely to require consent.

Works Not Affecting the Listed Building

Works entirely within a garden or grounds that do not affect the listed building itself or any listed curtilage structures do not require listed building consent, though they may require planning permission depending on their scale and nature. New planting, garden furniture, and non-structural garden structures that do not affect the setting of the listed building typically do not require consent.

Summary

Listed building consent is not required for genuine like-for-like maintenance using the same materials and methods, for internal works that do not affect the building's special character, or for garden works that do not affect the listed building or its curtilage structures. The test is whether works preserve existing character without altering it. When uncertain, seek pre-application advice from the conservation officer before starting work.
