A Heritage asset is defined in the glossary of the National Planning Policy Framework as:
A building, monument, site, place, area or landscape identified as having a degree of significance meriting consideration in planning decisions, because of its heritage interest. Heritage asset includes designated heritage assets and assets identified by the local planning authority (including local listing)
Designated heritage assets include international designations (World Heritage Sites) and nationally designated assets identified by English Heritage and DCMS
Designated heritage asset:
Non-Designated heritage assets include archaeological sites contained within the historic environment record and buildings added to a local list.
JME Conservation will assess the significance of designated heritage assets and non-designated heritage assets defined by the Local authority and advise clients about the potential impacts of their proposals upon these heritage assets and how best to resolve issues that arise.
