Certificate of Lawfulness in Poole
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 Poole, where a mix of 1930s semi-detached homes in Parkstone, Victorian terraces in the Old Town, and premium detached properties around Sandbanks and Canford Cliffs, 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 Poole
BCP Council follows standard Permitted Development rules. Single-storey rear extensions up to 4m (detached: 8m) from the original rear wall do not require planning permission, subject to conditions on height, boundaries, and materials. The Poole Harbour area has specific flood risk considerations that can affect foundation design. We factor this in from the outset 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 BCP Council and manage the process through to the certificate being issued.
