SAP calculations
New dwellings
All new dwellings must have a SAP calculation performed in order to demonstrate compliance with Approved Document L1A of the Building Regulations.
Extensions
If you build an extension where the glazing is over 25% of the floor area, then we can undertake a SAP assessment to demonstrate compliance with Approved Document L1B.
Conversions
If you renovate a building such that there has been a material change in use, then we can undertake a SAP assessment to demonstrate compliance with Approved Document L1B.
