Planning Permission is NOT Required
If the area of hard surface is constructed using a permeable product there is no limit to size in this case. Standard impermeable paving can be used if provision is made for rainwater from traditional impermeable hard landscaping to drain into a soft landscape such as grass or border planting with sufficient permeability, or into a specially constructed soakaway. If the area of hard surface intended is less than 5 square metres. The new legislation only affects front garden areas. Elsewhere around the house there are no restrictions on hard surfaces at or near ground level.
Planning Permission is required
If rainwater from the impermeable hard surface at ground level has nowhere to run other than into the household drainage system or on to the public highway. If the property intended for work is a listed building. Conservation areas, World Heritage sites, National Parks and Areas of outstanding natural beauty may have some restricted permitted development rights for householders. Better to enquire in advance in such circumstances. It is the homeowners’ responsibility to apply for planning permission
