Open Days were held at Redhill, and included the formal opening of the new and expanded fire testing laboratories, after being transferred from Ashtead. The opening ceremony was carried out by Dr Ivor Dunstan, Chief Executive of the Building Research Establishment. Of necessity the transfer of the Ashtead staff and facilities had taken place over a period of several years. In 1979 the Redhill site embraced a very wide range of activities, namely polymer engineering, consultancy, physical, mechanical, electrical, thermal and analytical testing, as well as fire testing and building investigations, all under a new company name, Yarsley Technical Centre, (YTEC).
