How we help

Having years of experience carrying out SAP calculations for extensions, we can make sure your design gets planning permission with little or no change to your original proposed extension design.

To carry out these calculations we would require:

• Your existing site plans and your proposed extension site plans
• Proposed construction and building service details.

The notional v. compliant SAP calculation is a desk top exercise, removing the need for a site visit. We can also get in touch with your Building Control Officer or Planners, and guide you through any particular local requirements
