Update on FSAP 10.2 Release

We have been working hard on getting FSAP 10.2 ready for the implementation of Part L 2021 next month. This involves going through a rigorous approval process, managed by BRE on behalf of BEIS. The approval process requires FSAP 10.2 to calculate and match results for a number of standard test cases provided by BRE. The test cases have seen some delays and corrections, and therefore to ensure SAP software is ready for 15th June, the approval process has now been changed.

BRE has now provided three batches of test cases prioritised to cover the majority of technologies expected to be used in new homes. The technologies the three batches cover:

Batch 1

  • Building fabric (walls, roofs, floors, windows etc.)
  • Boilers (mains gas, LPG, electric, oil)
  • Secondary room heaters
  • Instantaneous WWHRS
  • Solar heating (hot water only)
  • Natural ventilation with intermittent extract fans
  • Centralised MEV
  • Decentralised MEV
  • Balanced ventilation with heat recovery (MVHR)
  • PV (without battery or diverter)
  • Air conditioning

Batch 2

  • Electric heat pumps
  • Electric immersion
  • PV with battery
  • PV with diverter
  • Wind turbine

Batch 3

  • Community heating (not from PCDB)
  • Balanced ventilation without heat recovery

Validation for the remaining technologies (below) will follow after these batches.

  • Storage WWHRS
  • Solar heating (space and water heating)
  • Community heating from PCDB
  • Positive input ventilation
  • Anything else not mentioned above

BEIS and DLUHC have authorised SAP software products for limited release to users when at least batch one is approved by BRE. Where SAP software is not yet approved for a batch, the technologies within that batch should not be used for completing SAP assessments or compliance calculations under SAP 10.2.

When FSAP 10.2 is ready for release we will confirm for which batches we are approved.

We envisage that full capability will be available no later than 31 Jul 2022.

We will update all members once each batch meets the BRE approval process.

We trust you find this update useful and will keep all members updated with developments over the next few weeks.
