There is no substitute for experience. With 30 years’ experience in the costing industry, John M Hayes has the advantage over its competitors: it’s what sets us apart. Highly regarded for both our legal aid and inter partes work, our experience ranges from preparing claims for costs in low value family legal aid matters to undertaking the full assessment process in complex commercial litigation claims of very high value.

The development of a National Advocacy Team complements our existing services with specialists to appear at any costs-related matter. Our expert team has experience in representing parties at costs management conferences and detailed assessment hearings in courts throughout England and Wales.


We are unique. With 10 offices established throughout England and Wales we are able to offer what other firms simply cannot: nationwide coverage coupled with working local knowledge.
