We are currently completing design from Stage 4 to 5. The project has been on going since 2020 with a completion date of September 2024. There was a design Freeze in April 2022 which was signed off by fire engineer and building control.
Within BS7671 the regulation states that all installations "certified" after 27th September 2022 must comply with BS7671 AMD 2. Our query relates the the word "Certified" and what this relates to? Is it when the system is fully tested and a completion certificate received or is it when Building control sign the design as acceptable? Or does it relate to something different?
