Why does my project need a SAP Calculation?

SAP Calculations for Conservatories are to demonstrate that your project complies with Approved Document Part L1B. They are only required when the glass exceeds the 25% glazing to floor area ratio rule under Building Regulations. Or if you decide to remove the thermal wall between the dwelling and conservatory.

Where do we fit in?

The process to compliance is simple. A SAP calculation for the proposed project is composed and run against the critrea with Approved Document Part L1B, once this is done we issued the completed SAP calculation with a brief cover report for you to follow.

How to Get a SAP Calculation

The process is simple. Start by emailing your drawings to us, we will then issue a quote. Once payment has been made we will get to work on the calculation. At S-W-E-A we are well aware of the current cost to build out a project, so any changes made will be as minimal as possible.
