Thompsons’ Cardiff office was established in 1965 to provide expert legal advice and representation to people across South and Mid Wales.

As the UK’s leading trade union law firm, our lawyers have acted for thousands of workers and worked closely with industrial and mining communities throughout our long history.

Today, Thompsons continues to work alongside the union movement and the Welsh Labour government to champion the rights of workers and the injured across Wales. The specialist teams in our Cardiff office have significant litigation expertise and experience in dealing with personal injury claims, asbestos disease claims, and accident at work claims. Our office in the Welsh capital also has dedicated teams dealing with employment rights and criminal law on behalf of trade union members and a specialist team of medical negligence lawyers.

All members of our Cardiff team are English speakers, but should you feel more comfortable speaking in Welsh, we have a number of fluent Welsh-speaking staff and lawyers who will be more than happy to help.

Beginning your personal injury claim only takes a few minutes – call 0800 0 224 224 today to speak to a legal advisor or fill out our quick, free and no obligation online claim form.


I received an excellent service from Thompsons Solicitors. I was constantly updated on proceedings, and treated with care and understanding. It was reassuring to know that the Thompsons Solicitors team were there with you at every step throughout.
