Wiltshire Council has now prepared a draft Local Plan. This is the county-wide version of the Marlborough Neighbourhood Plan which was finally agreed in March 2023.
The Plan is now being offered for public consultation with in-person events being held around the country. The session in Marlborough is to be held on Monday 9th October from 3pm to 7pm at Marlborough Library, 91 High Street, Marlborough SN8 1HD.
If this time and locations are not convenient for you the other drop in sessions are listed on https://www.wiltshire.gov.uk/planning-policy-local-plan-review, otherwise there is an online event you can register for.
