SAP calculations are often needed for extensions to existing properties. This is required if the new glazing of an extension accounts for more than 25% of the new floor area, if the extension is not thermally separate from the existing house, or if the extension does not comply with Building Regulations for conservatory glazing.
We carry out these calculations from existing and proposed plans, and the proposed construction and services details, we don’t need to visit the site but if these details are not available we can visit and sort all of the required information and measurements.
We work with our clients to advise the best way forward and find a solution that ensures their extensions achieve Part L1B Building Regulations compliance, guiding them through the process. We can provide further details and criteria on this element of Building Regulations once we know the details and attributes of the planned extension.
