Certificate of Lawfulness in Blandford
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 Blandford, where a Georgian town rebuilt after the 1731 fire, with beautiful Georgian townhouses in the centre, post-war estates, and rural farmhouses on the outskirts, 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 Blandford
Dorset Council covers a large rural area with many villages in conservation areas and AONBs (Dorset AONB, Cranborne Chase AONB). Permitted Development rights may be restricted in these areas — always check before assuming PD applies. Blandford's Georgian architecture is its defining feature — Dorset Council expects extensions in the conservation area to be designed with great care and matching materials 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 Dorset Council and manage the process through to the certificate being issued.
