A soakaway does not normally require an application for planning permission provided it deals with surface water and does not discharge into a public sewer. Additional regulations may apply if you are in a conservation area or within the boundary of a listed building.

Building regulations will apply to the creation of a soakaway. The soakaway must comply with Part H of the building regulations which specifies where they can be located and the size that is permitted.
