Can I extend my house in BR8?
Swanley looks like a Bromley postcode. Most of it is Sevenoaks District Council. Places in this outward code include Swanley, Hextable, Crockenhill.
Check the authority before you check the policy
BR8 is the reminder that an outward code is not a council. Swanley and Hextable are in Sevenoaks District, in Kent, even though the postcode is BR. A sliver of the fringe can fall inside Bromley. postcodes.io, which every report starts with, is how we tell them apart.
Sevenoaks and Bromley do not apply the same householder policies. If the house is in the Green Belt, Sevenoaks has used a numerical cap over the original dwelling in the decisions we sampled further east, in DA3. Do not assume that cap applies, and do not assume Bromley’s side-space policy applies, until the authority is confirmed.
