SKA Rating


What is Ska?

Launched in 2009, the Ska is a point based environment assessment system for sustainable UK fit-out projects run by the Royal Institute of Chartered Surveyors (RICS).


How does it work?

The Ska system has a strong focus on more specific energy efficiency improvements to services (such as lighting), rather than overall CO2 emission rate.

By using the SKA rating, projects benefit from environmental performance and quality assurance assessments, an RICS-accredited certificate and are awarded either a Bronze, Silver of Gold status depending on the overall points awarded.


How is it relevant to lighting?

Lighting can contribute to the overall points that a project is awarded and help determine its status level. In order to score in the lighting section, the overall scheme (whole system including driver) must be less than 11W/m2. In addition, products must be compliant with the latest criteria published on the Energy Technology List (the requirements to be met for Enhanced Capital Allowance). Information about ECA and the Energy Technology list can be found on the PhotonStar website here.


Key aspects of the Ska system

  • Flexible scoping: match the rating to the scope of the fit-out 
  • Easy-to-use online tool
  • A simple Bronze, Silver and Gold rating, plus a percentage score 
  • A formal, quality assured scheme for those who require a certificate
  • Applicable to offices (retail version currently under development)
