When You Don't Need Planning Permission
Most standard roofing work on standard domestic properties in Wiltshire falls under permitted development — you can carry it out without making a planning application. This includes:
- Like-for-like tile repairs in matching material and colour
- Full re-roofs in the same tile type
- Lead valley and flashing replacement
- Rear-slope Velux installation on standard properties (not listed, not conservation area)
- Ridge and chimney repointing
- Flat roof replacement in like-for-like or equivalent material
The key principle is that like-for-like work in matching materials on a standard domestic property doesn't require consent. The complications arise when materials change, when the property is listed or in a conservation area, or when the alteration is visible from a public highway.
When You Do Need Permission or Prior Notification
Listed Buildings
Permitted development rights don't apply to listed buildings. Any alteration — however minor — to a listed building requires listed building consent before work begins. This includes like-for-like repairs that would be permitted development on a non-listed property. The test is whether the work affects the character of the listed building, and the conservation officer has broad discretion. We always confirm listed building status during the free survey and will not commence work on a listed building without consent confirmation.
Conservation Areas
Wiltshire has extensive conservation area coverage — Chippenham's town centre, Corsham, Box, Lacock, Bradford-on-Avon, Devizes, Malmesbury and many villages. In conservation areas, permitted development rights for roofing work are more restricted than standard. Front-slope roof windows require prior notification. Changes to materials visible from the street require consideration. The principle is that the character of the conservation area must be preserved. See our full conservation area roofing guide for detailed specification requirements.
Material Changes
Changing the roofing material — concrete tile to clay, felt to GRP on a visible flat roof — may require prior notification in conservation areas or consent on listed buildings. On standard domestic properties outside these designations, material changes are generally permitted development as long as they don't materially alter the external appearance. We advise on what requires notification during every survey.
The Practical Approach
The planning rules for roofing work in Wiltshire are not complicated once you know which category your property falls into. The sequence is:
- Is the property listed? If yes — listed building consent required for any alteration.
- Is the property in a conservation area? If yes — more restricted permitted development applies.
- Is there an Article 4 Direction on the property? If yes — permitted development rights may be removed.
- If none of the above — standard permitted development applies for like-for-like and material-upgrade work.
Our approach: We confirm planning status during every free survey on conservation area and listed building properties before any specification is agreed. We will never advise you to proceed with work that would create a planning breach.
Retrospective Consent
If work has been carried out without the required consent, retrospective planning permission or listed building consent can sometimes be applied for. This is always less certain than prior consent — the planning authority may require the work to be undone if consent is refused. In Wiltshire, the use of concrete tile on a conservation area property or any unapproved work on a listed building is taken seriously by the planning enforcement team.
