Do I Need Planning Permission for a Swimming Pool?

Most outdoor swimming pools in England do not need planning permission when they are in the rear garden, behind the house, and do not dominate the garden. Pools are treated as garden structures under permitted development, subject to size and placement rules.

• Pool is located behind the principal elevation of the house
• Less than half the garden area is covered by buildings and additions (including pool surrounds)
• Pool structure is not more than 4 metres high (if enclosed)
• Not within 2 metres of a boundary if over 2.5 metres high
• Property is a house with permitted development rights intact
• Pool is for domestic use only, not commercial

• Pool is forward of the house or visible from a highway in a conservation area
• Property is a flat, maisonette or listed building
• Pool enclosure or building exceeds permitted development height or footprint limits
• More than half the garden would be covered by structures
• Permitted development rights removed locally

A pool house, changing room or enclosure may be treated as an outbuilding. Outbuilding rules on height, footprint and boundary distances apply in addition to pool-specific considerations.

Swimming pools may need building regulations approval for drainage, electrical work and structural elements. Safety fencing and water supply rules are separate from planning permission but are essential before use.
