Thompsons’ Llanelli office was established by the late Jeffrey Parsons as J.M. Parsons & Co, and continues to trade under this name to this day. Jeffrey started the firm with the aim of supporting power plant and steel workers in Wales who were suffering from industrial diseases, including asbestos-related diseases such as mesothelioma. Amanda who works there today trained with Jeffrey.

As the UK’s leading trade union law firm who also ran the first asbestos case to the House of Lords in 1972, Thompsons welcomed J.M. Parsons & Co into the firm in 2016. Together the firms have acted for thousands of workers and have led the field in obtaining justice for asbestos victims across Wales and beyond.

The Llanelli team wins, on average:

- Nearly £1 million in damages every year

- Almost £850,000 in compensation for asbestos clients each year

Since its formation in 1921 Thompsons has only ever acted for the injured, never for those who cause injury, and has always been proud to work closely with the union movement and the Welsh Labour government to champion the rights of workers and the injured throughout Wales. The firm and our Llanelli office have unrivalled expertise in dealing with asbestos disease claims, but are also experienced in dealing with other industrial disease claims, as well as accident at work, personal injury and medical negligence claims.

All members of our Llanelli team are English speakers, but should you feel more comfortable speaking in Welsh, our fluent Welsh-speaking staff will be more than happy to help.  



Amanda Jones, Thompsons partner and specialist asbestos solicitor, is based out of the Llanelli office, with Catherine Cladingbowl who also runs the Cardiff office as the regional managing partner.
