Historic England's 'Latest Research' web feature includes an article on the development of a Local Listed Building Consent Order (LLBCO) for Port Sunlight. An LLBCO enables a local planning authority to grant listed building consent for specified works to designated buildings within their area. For example, this might include common works such as kitchen fittings within a large, listed housing estate. The intention being that routinely consented works of a similar nature can be undertaken with less time and resource.
