No official Lewes District Council statement on beach metal detecting was found; the shared lewes-eastbourne.gov.uk site blocked automated access. Telscombe Town Council bans detecting on its own land (clifftop Telscombe Tye etc.), not the beach.
We couldn't find a published rule. Foreshore owned by the Crown Estate follows the Crown Estate's terms; for council-owned beaches, ask the council before you dig.
Tap any spot in England on the UK Detector map to check it against scheduled monuments, SSSIs, nature reserves, National Trust land and access land in one go. Free: 3 checks a day.
