Building work that is granted planning permission by national rules, so no planning application is needed, provided set conditions are met.
Building work that is granted planning permission by national rules, so no planning application is needed, provided set conditions are met.
Permitted development in practice
Permitted development rights allow certain types of work, such as many extensions, loft conversions, outbuildings, solar panels and air source heat pumps, to go ahead without a planning application, as long as the conditions for that type of work are met. The rules are set nationally, and they differ between England, Wales and Scotland.
The rights are restricted or removed in some places: in conservation areas, on listed buildings, in World Heritage Sites, for flats in many cases, and wherever a council has made an Article 4 direction. Permitted development only concerns planning. Building Regulations, listed building consent and party wall duties can still apply.
