When are SAP calculations required?
If you are beginning a new construction project for a residential property, you may be required to complete SAP calculations.
What is a SAP calculation?
A SAP calculation measures how energy efficient a property is and is the base calculation for an EPC (Energy Performance Certificate).
Building Regulations require a SAP calculation to be carried out for all new residential developments – otherwise the project may not be approved.
So, when are SAP calculations required?
SAP calculations for new builds
All new residential property developments require a SAP calculation in order to create an accurate EPC. The SAP calculation creates a score that predicts the property's annual energy cost, which may affect the new residents of the property. A predicted EPC should be submitted prior to any development taking place so this process must be started in the early development stage.
SAP calculations for extensions
A SAP calculation is not always required for an extension. However, if an extension has glazing larger than a quarter of the floor area, a SAP calculation is required. If you are unsure how much glazing your extension has, you should contact an energy consultancy company who will be able to advise you further.
SAP calculations for conversions
A SAP calculation must be completed for all residential conversions; this is to ensure they comply with all relevant regulations. For example, a commercial building with an EPC certification will still need a SAP calculation if it is being turned into a domestic property/properties.
