Cardiff Energy Conservation Codes - New Builds & Refurbs
In Cardiff, Wales new builds and refurbishments must meet statutory energy conservation standards set under the building regulatory framework and local building control processes. This guide summarises the applicable technical guidance, the enforcing authority in Cardiff, typical compliance steps, and how to apply, appeal or report suspected non-compliance. It is written for developers, architects, landlords and homeowners preparing building regulation submissions or retrofit works in the Cardiff local authority area.

Local compliance is managed through Cardiff Council's Building Control and planning functions. For technical standards and permitted methods refer to the Wales Approved Documents and Cardiff Council guidance as the controlling instruments in practice.[1][2]
