Rebecca has been campaigning hard on local issues, fighting for the protection of Castle Point's Green belt from Labour's centrally imposed building targets, working with residents groups against inappropriate industrial development on Canvey Island, especially Methane storage, and seeking improved infrastructure across the Borough.

Rebecca also supports numerous Castle Point charities and community groups, including as a patron of Carers Choices, The Danny Green Fund, The Cascade Foundation, The Micky Payne Memorial Foundation and the Southend-on-Sea Railway Travellers’ Association.
