About Us

Riordan Associates is a highly renowned firm of cost lawyers.

Before embarking on fulltime careers in costs both Brian and Doug were employed as Litigation Executives and therefore have practical experience in dealing with the day to day running of cases.


Riordan Associates has a diverse client base acting on behalf of large City and West End firms of solicitors, Trade Union solicitors and Local Authorities.

We have also acted on behalf of London based US law firms and on behalf of the US government.


We are committed to find individual costs solutions for each of our clients and offer a truly bespoke service. We aim to meet your requirements and provide a comprehensive, individually tailored solution as we recognise that the needs of each firm are different. Our dedication to providing outstanding service has enabled us to establish long term relationships with our existing clients.
