Built on a Sound Foundation

  • We have to dream. How else will we make a future that does not yet exist

    Founded in 1990 by Graham Preston and Mark Payne with a passion to provide excellent audio to events and a vision to gather a team of like minded individuals to make a difference.

    Tom Jeffery joined in 2001 in a Business Development role and is now our Managing Director.

  • 2003 saw Craig Lawrence become a member of the team with the acquisition of 6th Sense Solutions. He is now our video and projects director steering the development of our technical strategy.

  • 2006 saw the re-branding of Sound Foundation to SFL, reflecting the business diversity and wide range of solutions we offered to our clients.

    In 2008 the company ownership structure was adjusted, recognising the value of the next generation therefore ensuring that the company has encoded into its DNA sustainability and security for the next generation.

  • As a long term user and installer of d&b for over 20 years, in 2016 we were proud to have been appointed to represent d&b audiotechnik as official UK sales partner.

    Our desire to be able to support customers nationwide lead to us welcoming Scottish-based FE live to the family. This also grew our capabilities enabling us to support large-scale concerts and international touring with musicians such as Lewis Capaldi.
