SAP Calculations for Conversions

If you are converting a building or changing it’s use, you will need to produce SAP Calculations to demonstrate the energy performance of the new dwellings.

Whether you are converting a church or turning a factory into flats, the Part L1b regs require that controlled fittings, services and building materials meet certain efficiency standards, and that the resulting building meets carbon targets.

Performing a SAP Assessment demonstrates to building control, and indeed planners that you are meeting building regulations requirements and local policies, and also provides the means to produce an Energy Performance Certificate (EPC) at the end of the build.

We can help you through the process simply and quickly.

How Does it Work?

BREEAM Assessment

We undertake SAP calculations from existing and proposed plans, and a detailed specification for construction and services. The assessment is carried out from our offices so there is no need to visit site or carry out any surveys.

There are several routes to demonstrate compliance and we will work closely with the client to make this as easy and pain free as possible. The assessment takes place over two stages – design, where we ensure that the proposed design meets the L1b requirements, and as-built, where we issue final reporting and an EPC for any newly created dwellings.

We will ensure that both new and existing elements are up to scratch, identifying how existing walls, floors and roofs may be upgraded and how new features such as heating and insulation should best be integrated.

We work with you right throughout the build process, from start to finish, and we are always on call to provide guidance and advice.
