Stuart Fairlie – Managing Director at Elmhurst:

“We are delighted to see the response to the Stage 2A consultation published. Our first observations are that with the reduction of the transition period to one year the Welsh Government are intent on delivering really meaningful new standards as quickly as possible. Certainly it is very much aligned with our official response. We fully support the meaningful step towards 2025. We must all work together to ensure that the timelines are achievable for all stakeholders. It looks like 2022 will be a very busy and exciting year for our members.”
