Domestic, commercial and new build EPCs — issued by an accredited SAP and iSBEM assessor based in Northern Ireland.
An Energy Performance Certificate (EPC) rates a building's energy efficiency on a scale from A (most efficient) to G (least efficient). It is a legal requirement when a property is built, sold or rented.
In Northern Ireland, EPCs are lodged on the NI EPC Register. For new dwellings, a Design Stage SAP calculation is typically required for Building Regulation approval before construction begins, followed by an As-Built EPC on completion.
For non-domestic buildings over 50m², an iSBEM assessment is used instead of SAP to demonstrate compliance with Technical Booklet F2.
For NI Building Regulation approval, most new dwellings require a Design Stage SAP calculation submitted with your planning or Building Control application. An As-Built EPC is then issued on completion. We handle both stages.
Northern Ireland operates under its own SAP edition — SAP 2009 with Conventions v5.0 and Technical Booklet F1 for dwellings. This differs from England and Wales. Local expertise matters.
