SAP Assessments & EPC's

Solution led - Design options - Achieve compliance.
Today more than ever, the need for energy efficient buildings, good levels of insulation, lowering heating bills, & an understanding in how to achieve this, has never been higher.

SAP works by assessing how much energy a dwelling will consume, when delivering a defined level of comfort and service provision.

The assessment is based on standardised assumptions for occupancy and behaviour. This enables a like-for-like comparison of dwelling performance. Related factors, such as fuel costs and emissions of carbon dioxide (CO2), can be determined from the assessment.

Select the type of SAP you require from the options below.

We also offer Heat Loss Calculations, which can be utilised to calculate the total heat loss of the dwelling and provide a room-by-room breakdown of the property to aide in sizing an Air or Ground Source Heat Pump.
