TTL was the named division of Asbestos Surveyors UK Ltd which was formed in 2009 and went through a name change in 2011 to Assisi Environmental Services Ltd.  Originally formed to carry out the ‘testing’ duties of AS UK it was decided that The Testing Lab was becoming a strength of its own and it was incorporated under a separate identity in 2010.  Today the activities of The Testing Lab Ltd have far outgrown its parent company and as such it was decided to allow TTL to forge ahead and create the brand.  Today TTL aims to take full control of all activities under one roof.

Our teams of technical site staff are strategically placed throughout the UK, all are controlled via our National Control Centre in Doncaster, South Yorkshire.

We provide services in the following compliance disciplines:
