Do I need planning permission in Dover?
In England the main routes are permitted development (ideally confirmed with a lawful development certificate, £274), larger home extension prior approval (£249, 42 days) and a householder planning application (£548, normally 8 weeks), with council fees as set from 1 April 2026.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
Working in Dover
Postcode districts we cover around Dover include CT16, CT17. We also work in nearby Folkestone (7 miles), Deal (8 miles), Canterbury (15 miles), Ramsgate (15 miles).
Just over the East Sussex border, Hastings is about 37 miles away. In the South East, plenty of houses have already been extended once, which makes checking the remaining permitted development allowance an important early step.
