SAP Assessments Across Wales / Asesiadau SAP ledled Cymru

Design-stage and as-built SAP assessments for new homes, conversions and qualifying extensions, with clear compliance advice from an Elmhurst-approved On Construction Domestic Energy Assessor and Chartered Architectural Technologist.

NEW DWELLINGS

Design-stage and as-built SAP assessments for individual homes and small residential developments. Early assessment helps establish suitable fabric, heating, ventilation and renewable-energy specifications before construction begins.

EXTENSIONS

SAP calculations may be required where an extension contains extensive glazing or cannot satisfy the usual elemental requirements. A whole-dwelling calculation can demonstrate that the completed property achieves the required overall performance.

CONVERSIONS

SAP assessments for barns, commercial buildings and other properties being converted into dwellings. The assessment considers the retained construction alongside proposed thermal upgrades and building services.

WHAT IS A SAP ASSESSMENT?

A SAP assessment calculates the predicted energy performance of a dwelling and is used to demonstrate compliance with Part L of the Building Regulations. It considers the building fabric, heating, hot water, ventilation, airtightness, renewable technologies and other aspects of the design.

SAP assessments are normally completed during the design stage and updated following construction to produce the final compliance documents and Energy Performance Certificate.
