EverRoof

I visited Attain RTC in October 2025 to observe BRoof (t4) fire testing carried out on two different roof build-ups. During our time at the centre, we were given a comprehensive tour of the facilities and had the opportunity to meet with members of the team, who were professional, knowledgeable and welcoming throughout. Attain also provided assistance with budget quotations for future testing programmes and were always on hand to offer guidance and support when required. The service provided was efficient and helpful at every stage of the process.I would not hesitate to recommend Attain RTC.

I visited Attain RTC in February 2025 to observe a number of BRoof (t4) fire tests. All the members of staff I came into contact with were both friendly and hospitable and I felt comfortable and confident during the course of my observations. Also, there was a requirement for further information after the classification report was issued and Attain RTC provided the necessary details at no extra charge. I would not hesitate to recommend this company.
