England
Front hard surfaces are covered by Class F of the General Permitted Development Order 2015. Where paving between the house front and the road covers more than 5 m², it must be porous or drain to a permeable area within the property, or it needs planning permission. Listed buildings, flats and maisonettes, and homes covered by an Article 4 direction (more common in conservation areas) can be different.
Wales
New or replacement front surfaces should be permeable or drain to a permeable area. Only repairs of up to 5 m² of existing surface are exempt. Separately, construction work of 100 m² or more with drainage implications, including drives and patios, needs approval from the SuDS Approving Body before work starts.
Scotland
Under Class 3C, a hard surface between the house and the road is permitted only if it is porous or drains to a permeable area, at any size. It is not permitted development in conservation areas or within the grounds of a listed building.
Northern Ireland
Under Class E of the 2015 order, a front hard surface covering or replacing more than 5 m² must be porous or drain to a permeable area. Listed buildings need consent. Check with your council's planning office if in doubt.
Dropped kerbs
Crossing the pavement needs the highway authority's approval: the council in England, Wales and Scotland, and DfI Roads in Northern Ireland. In England a new access onto an A, B or C classified road also needs planning permission.
More questions
What is the 5 m² rule?
In England and Northern Ireland, up to 5 m² of ordinary (non-permeable) paving at the front of a house is allowed without permission. Above that, the surface must be permeable or drain within the property.
Does permeable block paving need planning permission?
Not usually for a house, in any of the four nations, though listed buildings, conservation areas (in Scotland) and Article 4 directions can still require it.
Do Building Regulations apply to block paving?
A drive itself does not normally need Building Regulations approval, but paving must not bridge the damp-proof course, and drainage connections must follow the rules.
