About Deep Blue Costs


About Us

Deep Blue Costs was established in 2015 by Mark Carlisle – a Costs Draftsman who began his career in costs in mid-1980, with numerous appearances at the Senior Courts Costs Office, and outstanding results at hearings generally.  Mark formed the company with a view to providing the best possible service to his clients by using only very experienced Costs Lawyers and Costs Draftsmen.

As a result of this approach, we are able to provide exceptional quality and service, including precise and accurate advice, excellent drafting and negotiating skills and the highest standard of representation at hearings.

We have offices in Warrington and London.
