This year marks 100 years of working shoulder-to-shoulder with trade unions and fighting for the injured and mistreated. 

Thompsons was founded in 1921 by Harry Thompson and was built on a vision of using the law to provide justice for working people. Today, that vision lives on in our expert litigation teams who, together, form the most experienced personal injury practice in the UK.

We are proud that our specialist personal injury lawyers, industrial disease experts, accident at work claim specialists, serious injury solicitors and medical negligence lawyers are fully regulated, accredited and recognised for their skill, empathy and expertise by the likes of the Association of Personal Injury Lawyers, Action Against Medical Accidents, Chambers & Partners and the Legal 500.

Why choose Thompsons Solicitors

Every year, Thompsons secures hundreds of millions of pounds in damages by investing our wealth of expertise and specialist knowledge into each and every personal injury case.

We have a reputation for fighting harder to secure the highest possible compensation settlement from the party at fault than any other law firm.

Unlike other law firms, we are dedicated to claimant-only work: our teams only ever act for the injured or mistreated person. We have never, and will never, represent employers or insurance companies – those who are responsible or pay out for injuries.

To act for both sides would, in our opinion, undermine our ability to secure the best outcome for the tens of thousands of individuals who come to us each year seeking financial and legal redress from those responsible for their injuries.

We know whose side we are on and have pledged our commitment to injured people.

    William Henry 'Harry' Thompson founds Thompsons Solicitors.

  • 1921

    The Local Authorities (Financial Provisions) Act 1921 is rushed through parliament after Thompsons acts for Labour councillors in the Poplar Rates Rebellion, a protest against the poorest boroughs of London paying the same tax as the richest.

  • 1926

    Thompsons represents Poplar Borough Council, this time in a wages dispute and, primarily, women’s pay. The case is ultimately lost and Poplar councillors have to pay penalties for increasing their minimum rate of pay to £4 a week regardless of the work done or the person doing it. This was an early precursor to the concept of equal pay for work of equal value.

  • 1926

    Thompsons works tirelessly to support miners and other workers taking part in the General Strike against longer working hours for less wages.

    The UK fall-out from a politically motivated trial in India (known as the Meerut Conspiracy Case) is taken up by Thompsons, which represents three English textile workers denied bail and refused a proper jury trial. The criminal case lasts for many years and leads to the conviction of all three, before going to appeal where their sentences are dramatically reduced.

  • 1934

    Thompsons secures damages for trespass on behalf of the National Unemployed Workers Movement, after documents are seized illegally and used as the basis for a charge against the client.

  • 1947

    Harry Thompson dies after complications following an operation, leaving behind his two sons to lead what is by now Britain’s leading trade union law firm.
