What is an L1A SAP Calculation?

It is the Part L energy assessment required for newly constructed residential dwellings.

When should the SAP calculation be completed?

The design-stage assessment should ideally be completed before construction begins.

What information do you need?

We normally require architectural drawings, construction specifications, glazing details, heating, hot-water and ventilation information.

Will I receive an EPC?

Where applicable, the EPC is prepared following completion of the compliant as-built SAP assessment.

Can you help if the design does not comply?

Yes. The assessor can recommend practical improvements to insulation, glazing, heating, airtightness or renewable systems.

Do I need an air tightness test?

New dwellings commonly require a final air permeability result for the as-built SAP assessment, subject to the applicable testing requirements.

Do you assess housing developments?

Yes. We work on individual dwellings and multi-unit residential schemes of varying sizes.

What information is needed for a quotation?

Provide the address, dwelling numbers, drawings, design stage and available construction and service specifications.
