RSAP+ - Energy Assessment Software

RSAP+ is an industry-leading energy assessment software suite for Stroma Certification members. Its component modules perform a variety of energy assessment calculations, processes and data management functions to make life easier for our users and members.

Stroma Certification's RSAP+ modules are now BRE approved to comply with RdSAP 9.92.

To access all of the modules, get a user account – or ask us for a free trial.

We designed RSAP+ for our members – whether they're Domestic Energy Assessors, Green Deal Advisors or Assessor Organisations – and for the Green Deal Providers they work with. To obtain a user account and unlock its features, you will need to:

  • As an individual (i.e. Domestic Energy Assessor or Green Deal Advisor): join the relevant certification scheme operated by Stroma.
  • As an organisation (e.g. Green Deal Assessor Organisation, Green Deal Provider or energy company): agree that any assessors employed or subcontracted by you will lodge all assessments through the relevant Stroma scheme.

Not yet a Stroma member? Just ask us for a free demonstration account. We will give you access to the modules you're interested in for a predefined period, so that you can experiment with RSAP+ and understand how it could help your business.

RSAP available on the iPad
