To provide an Energy Performance Certificate (EPC) a significant amount of information will be required from each individual property. This data can readily be obtained by the respective Energy Assessor as part of the required site energy audit. However, time taken to obtain this data can be extensive and to avoid unnecessary costs it is advisable for clients to compile as much data as possible on the building and its operation, prior to the appointment of any EPC Assessor.

Letting Requirements
In order to establish the extent of EPC’s required details of the current and intended building use will be required in relation to type of activity, areas to be let to separate tenets and future development plans if any.

Site Location
Details of site address and contact names for access will be required.
