   Added to PlanIndex

Permission has been granted, usually subject to conditions listed on the decision notice, some of which must be discharged before work starts. The decision notice on the council portal sets out exactly what was approved.

Work must normally begin within five years of the decision or the permission lapses. Neighbours cannot appeal a grant; challenging one means judicial review of how the decision was made, within tight time limits.

A lawful development certificate is a legal determination, not a planning judgement. It asks the council to confirm either that existing use or works are lawful, often through the passage of time, or that a proposal would not need planning permission at all. The applicant must prove the facts; the merits of the scheme are not considered.

  51 Whitecliffe View Chepstow Monmouthshire NP16 5WJ

  We wish to make some small additions to our house constructed in 2024 and we need permission from the developer. They have asked us to check that planning permission is not required for the following: A. Solar panels on south facing roof B. Ariston air source heat pump on wall of house adjacent to our driveway and more than 1m from property boundary. C. 2 solar batteries on wall of house adjacent to our driveway. D. Very small shed behind garage in our back garden about 1m x 2m and 2.5m high. E. Wooden bin store, 124 cm wide ? 104 cm high ? 52 cm deep, next to the house and adjacent to our driveway. The property is not listed nor in a conservation area so I believe everything would be classed as permitted development but I would be grateful if you confirm this for us.
