OP Costs Drafting is a highly experienced costs consultancy that provides the complete spectrum of costs drafting services from preparation of bills of costs and points of dispute to costs budgeting, auditing and training. Our clients work in most areas of law, and they like the fact that, because of our size, we can offer one-to-one assistance, quick response times and a level of service that cannot be matched by bigger faceless nationwide costs drafting firms, or smaller sole practitioners.
