"Calculus are market leaders in the world of costs. They are really accessible and deliver clear, robust advice whilst pushing the boundaries on costs recovery. A hugely impressive outfit with knowledgeable, yet approachable people. "

Michael Goodridge, Director of Clerking at 9 Gough Chambers

"I have instructed Calculus on a number of matters and they have done a sterling job for me. They turn matters around quickly, prepare very robust bills of costs, are taken seriously by opponent costs firms and, most importantly, they are recovering substantially more costs for me than the previous costs firm I used, "

Adam Wright, Senior Consultant Clinical Negligence Solicitor, Setfords.

"Jon, thank you for sending me the draft replies, which are impressive. I like the succinct robust style, particularly in a case such as this where there was an agreed costs budget that has not been exceeded."

William Latimer-Sayer, QC at Cloisters

"Jon Cape has a wealth of costs knowledge up his sleeve and takes no prisoners in his approach on costs. He is calm but absolutely on the money with his knowledge and advice. Great to work with him over the years. "

Accredited Senior Litigator for APIL

"I have seen Calculus’ work a number of times over recent years, both when working with them and against them, and have always been impressed with their detailed knowledge of the law and procedure and their thorough preparation"

Roger Mallalieu, Barrister, 4 New Square

"I couldn't endorse John Hayes expertise enough. He is keen to work with firms to increase their profitability and is a shrewd negotiator on difficult cases. He goes the extra mile every time. Fantastic."

Sharon Allison, Partner, Ashtons Legal

"I have instructed Calculus for many years in relation to costs budgeting and settlement on high value, complex personal injury claims. The quality of their work, attention to detail, technical knowledge and negotiating skills are excellent. "

Gary Boyd, Partner, Gorvins Solicitors
