Dear LAEP practitioner,

Thank you for agreeing to provide data from your LAEP for Networks to understand how your LAEP plans impact plans in your area.
This document pack contains two folders, which outline how to prepare data for the different Networks interested in using your data to inform their planning.

Effort has been made to minimise the difference between these data dictionaries, with the intention of minimising the amount of additional effort required to prepare data for multiple audiences.
For example, for heating technologies for individual buildings, the formats are very similar and only differ in the technologies considered.
However, due to differences in how Networks use your data, some unavoidable differences do exist between the formats needed for the two dictionaries, so caution is advised to make sure that the data prepared aligns with the format required for the specific technologies.

The technologies requested by the different dictionaries are as follows:
