Credit Hire

Frederick is regularly instructed both for Claimants and Defendants to deal with road traffic accidents with elements of credit hire. He is often instructed to advise on evidence and tactics or conduct trials in such cases. He is familiar with all arguments commonly raised in credit hire cases including enforceability, need, period and rate. He has been instructed to draft training manuals for solicitors and other advocates in respect of these issues. Frederick is regularly involved on the multi-track in large claims involving the hire of prestige vehicles or taxi claims where hire has exceeded £50,000.

Although Frederick’s work is divided approximately evenly between Claimant and Defendant he has been instructed by  credit hire companies to draft generic documents and provide advice on tactics with ‘books’ of hire claims often exceeding several million pounds. Frederick’s work has resulted in bulk settlements being achieved in respect of the vast majority of these cases.

He is particularly sought after where complex matters of alleged fraud, enforceability or the hire of prestige vehicles are in issue.
