About Us

Who we are, what we do, what we've done
Costs Management was founded by Jason Harvey Osborn in 2005. Since then he has developed a strong association with the Commercial Legal Community. In the last 30 years Jason has had the pleasure of working with some of the biggest names in the industry. He was previously employed as the Litigation Group Costs Manager at Global Law Firm DLA Piper and was also a member of the Costs Team at Hogan Lovells.

Jason has been engaged in some of the largest costs litigation in the UK but with Client’s needs changing Jason has more commonly been engaged to advise, assist and support clients in a wider range of briefs.
From identifying suitable legal expertise to assisting with tenders and beauty parades. Jason and his team have negotiated and advised on the fine terms of business including advice and assistance on funding products and costs case budgeting and performance management.

Jason is a qualified Costs Lawyer with Higher Rights of Audience, a trained mediator and founder of his own Legal Practice and Costs Management business. His experience has found him retained in a multi track costs trial lasting over a period of months and producing what was described as one of the most comprehensive Scott Schedules (costs) ever seen in the Technology and Construction court.
Jason presently works with major international law firms and global commercial organisations as well as providing bespoke services for national businesses, high value individuals and boutique law firms.
…certainly specialists in the area of Costs. Their expertise and knowledge has resulted in substantial victories in Court…I would certainly recommend their services and often do.
