SKA rating

Environmental assessment method for your project

​SKA rating is an environmental assessment tool for sustainable interior fit-outs, and is a scheme owned and managed by the RICS. It measures and benchmarks the environmental performance of an interior project, no matter how small or large, and helps determine what elements will have the biggest impact on improving sustainability.

Grigoriou Interiors is a SKA Accredited Assessor for the OfficeRetail and Higher Education schemes.

Our involvement in and support of the SKA rating initiative has been instrumental in bringing the system into effect, both in the UK and internationally. Elina Grigoriou is the chair of the SKA rating Technical Committee and the Technical Advisor to the RICS team who own and manage the scheme.

Part of our initiatives in the scheme was to introduce a product and material compliance scheme, the SKA rating Compliant Product label, which would help suppliers and manufacturers align themselves with the scheme and help other designers and clients to quickly and reliably identify compliant items for their projects.


As an Accredited Assessor, we offer three levels of service:

  1. Basic SKA Assessment: as part of your project team, we will review the project during the scoping, design and handover stages, complete the relevant sections on the online tool and review the evidence provided. A summary report and Certificate (if achieved) will be issued at completion.
  2. Classic SKA Assessment: this option includes the Basic SKA Assessment together with additional sustainability guidance and answering queries during scoping to increase the project’s probability of achieving a SKA rating.
  3. Going for Gold: this option is suitable for projects aiming to achieve a Silver or Gold rating. In addition to the Classic SKA Assessment, we will support the design team with design solutions to meet target measures, provide material and product knowledge, support the project team to work through waste issues with a ‘Design Out Waste’ workshop, assist with the contractor selection process, provide guidance once on-site and be available for sustainability related queries.

Who is SKA rating for?

While primarily aimed at occupiers, SKA has benefits for other property stakeholders including landlords, developers and consultants. Clients interested in fitting out spaces in an environmentally positive way can use the SKA assessment scheme with our guidance as an Accredited Assessor to:

  • Provide a framework and guidelines to follow good practise and help decision-making
  • Follow a sustainable procurement process
  • Obtain a RICS Certificate if achieved
  • Benchmark the performance of fit-outs against each other and the rest of the industry

The SKA rating Product Compliant Label helps manufacturers, suppliers, specifiers and their clients quickly and easily find products that meet individual SKA rating criteria. Whether it is construction products, finishes, building services products, or furniture and fittings, seeing the label instantly confirms a product’s compliance with SKA rating.

We have been appointed by the RICS to deliver the application and review process for the SKA rating Product Compliant Label. We are:

  • Licensed by the RICS to review and issue the Label on its behalf
  • Experienced SKA rating development partners
  • Accredited SKA rating assessors for all three schemes (Office, Retail and Higher Education)
  • A dedicated, independent and unaffiliated review team.

Grigoriou Interiors assisted us with a SKA rating benchmarking exercise for one of our retail stores. They introduced us to the process and practice of SKA rating, assisted with evidence identification and questions from sub-contractors, explained how SKA rating could reduce environmental impacts on the project, and provided insights and recommendations to take forward. They were encouraging and informative throughout the process and we learnt a lot about SKA and the environmental  impacts of our fit-out process through working with them.

Elina and her team were brought on board to support us in delivering a challenging and thoroughly Derwent London project – the refurbishment of our HQ at 25 Savile Row. As with any Derwent London project design and sustainability are paramount to us, and Elina and her team were very quick to spot and appreciate this and develop an approach which worked in harmony with the project and our ways of working as a client. Their knowledge and expertise enabled us to really interrogate our designs and help us work towards our ambitious target of SKA Gold and BREEAM Excellent. However, in doing this they have taken the hard work out of things, were proactive in working with, motivating and supporting the design team and contractor, which as a client is really important and extremely valuable. I have been really pleased with their performance so far, and would have no qualms on bringing them onto more of our projects.
