Our founder, Thomas Lessels Dallas OBE, was an enterprising Scotsman who – after working with Christian Salvesen and Scottish Life – founded the eponymously-named TL Dallas in Bradford in 1919.

At the time of its establishment, there were over 300 textile mills operating in the town, and it was these entrepreneurs who formed the backbone of our early portfolio. In the years which followed, our client-base grew steadily, thanks to the acquisition – and retention – of many commercial customers, across a range of industries.

Fast-forward to the present day, and the TL Dallas Group has evolved into a modern insurance broking company, owned by our staff and management. Their dedication and expertise allows us to provide continuity of service to customers in a broad range of sectors.

We were also one of the founding members of UNA in 1997. A nationwide alliance of like minded insurance and risk management professionals we together place in excess of £500M premiums into the UK insurance market and share a wealth of expertise.

While our business has expanded and adapted considerably during its 100-year history, this fourth-generation family company remains true to its roots. We continue to have strong values and we believe that through living these values we can continue to provide an excellent service to all our customers and reward our own staff.


Thomas (Tom) Lessells Dallas left his home in Scotland and moved to Yorkshire, having secured a job at Roberts Insurance Brokers. He would later go on to marry the owner’s daughter Alice Eleanor Roberts (or Nell, as she was better-known). When his father-in-law died, Tom set up his own firm – likely utilising several contacts he’d made through his work at Roberts.
