When are SAP Calculations for Conversions required?

A SAP Calculation should be provided for development projects that result in the creation of a new dwelling as a result of a material change of use or when there has been a change of energy status.

Examples of material change of use include:

 

  • Development projects that result in the finished building being used as a dwelling where it previously wasn’t. This includes barn conversions and the conversion offices to self-contained flats. 
  • Instances where changes to the internal configuration of a building result in an increased number of dwellings. This includes the conversion of houses to flats or the reconfiguration of an existing development of flats to create additional units.
Residential Flat Subject to SAP Calculation

change in energy status occurs when a previously unheated space is subsequently designed to be heated or conditioned, such as the conversion of garage space or workshop to a residential dwelling. Energy status changes often occur in conjunction with material changes of use.

Conversion SAP Calculation – Frequently Asked Questions:

How do I obtain an Energy Performance Certificate for a Conversion Project?

New dwellings that have been created as a result of a material change, or a change in energy status, require an On Construction Energy Performance Certificate to support the sign off from Building Control.

The On Construction Energy Performance Certificate is derived from a full SAP calculation, which is also required to demonstrate compliance with the Building Regulations.

It should be noted that issuing On Construction Energy Performance Certificates is outside the standard competencies of Domestic Energy Assessors who use a simplified version of SAP (RdSAP) to produce Energy Performance Certificates for the existing housing stock based on a non-instructive survey.

What happens if the SAP Calculation fails?

Unlike new build dwellings, there is no requirement for SAP Calculations for conversions to demonstrate compliance with any minimum carbon dioxide emission rates (e.g. DER/TER of new builds).

Approved Document L: Volume 1, however, stipulate minimum thermal standards (U-values) for any existing and new construction fabric. Minimum performance efficiencies are also given for heating, hot water and ventilation systems.

When completing a SAP calculation for a conversion, we will advise whether the project specification complies with the minimum requirements of Building Regulations. If any shortfalls or issues are identified, we will also recommend appropriate specification changes as part of our works.

It is also worth noting that additional Government Legislation has introduced a Minimum Energy Efficiency Standard for rental properties which makes it illegal to let a dwelling in England and Wales with an EPC rating of an F or G, with this changing to C in 2027.

It is therefore vital to appraise the predicted EPC rating early within a project to ensure that the final EPC rating will not impact on the marketability of the dwelling on completion.
