Thanet has 27 conservation areas. These include Acol Conservation Area, Birchington Conservation Area, Broadstairs Conservation Area, Clifftop Conservation Area, Clifton Place and Grotto Gardens Conservation Area, Dalby Square, Cliftonville CA. If your property is in a conservation area, some or all permitted development rights may be restricted.

If your property is covered by an Article 4 direction, you may need planning permission for work that would normally be permitted. Contact Thanet planning department to check whether an Article 4 direction applies to your property.

Permitted Development Rules for a Swimming Pool
Generally permitted. Outdoor swimming pools are considered engineering operations within the curtilage and are permitted provided the pool area (together with all other outbuildings) does not cover more than half the curtilage. An enclosed pool building follows outbuilding rules under Part 1, Class E.
Conditions
- 1Must be within the curtilage of the dwelling
- 2Must not cover more than half the curtilage (combined with other outbuildings and extensions)
- 3If in an enclosed building, standard outbuilding height limits apply
- 4Must be for purposes incidental to the enjoyment of the dwelling
Size and Dimension Limits
- No specific pool size limit, but cumulative area must not exceed 50% of curtilage
- Enclosing structure: same height limits as outbuildings
When Permitted Development Does Not Apply
- Must not be forward of the principal elevation
- In designated areas, additional restrictions apply
- Indoor pool buildings are outbuildings and must comply with Part 1, Class E
- Consider the impact on drainage and neighbouring properties
What About Building Regulations?
Building regulations approval is not usually required
An outdoor pool does not normally require Building Regulations approval. An indoor pool in an enclosed building may require approval depending on the building's size and whether it has electrical installations, structural elements, or drainage connections. Electrical installations near a pool must comply with Part P and BS 7671 (special requirements for swimming pools).
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Thanet building control or use an approved inspector.
How to Apply in Thanet
If you need planning permission for your swimming pool, you can apply through Thanet's planning department or via the national Planning Portal.
If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Thanet. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
Low risk for outdoor pools within PD limits. Pools that significantly alter ground levels or drainage may attract investigation. Enclosed pool buildings that exceed outbuilding limits need planning permission.
