Certificate of Lawfulness in Salisbury
A Certificate of Lawfulness (CLPUD) is a legal document confirming your extension falls within Permitted Development rights. It is not planning permission — it is proof that you don't need it. In Salisbury, where a cathedral city with medieval properties in the Close, Georgian terraces in Fisherton, Victorian semis in Harnham, and modern estates in Old Sarum and Bishopdown, this certificate protects you when you come to sell.
Why you need one
Mortgage lenders, solicitors, and buyers expect documentary proof that extensions were built legally. Without a certificate, a future buyer's solicitor may raise enquiries that delay or derail your sale. The £1,500 investment now can save months of stress later.
PD rules in Salisbury
Wiltshire Council covers a large area including the city of Salisbury and surrounding villages. Salisbury city centre has extensive conservation areas, and parts of the county fall within the Cranborne Chase AONB. Standard PD rules apply outside designated areas. Salisbury has multiple overlapping conservation areas in the city centre. Wiltshire Council applies strict design guidelines for extensions in these zones We assess your property against all PD conditions before applying — if your project doesn't qualify, we tell you upfront and recommend the planning application route instead.
What we submit
Existing and proposed floor plans, elevation drawings, a site plan, and a compliance statement demonstrating how the proposal meets every PD condition. We submit to Wiltshire Council and manage the process through to the certificate being issued.
