Conservative candidate Tony Hogg was elected to the post in November in a major change in police governance which Ministers said would usher in a new era of accountability.
But Mr Hogg, a former Royal Navy commander from Helston, West Cornwall, has come under fire from a member of his own scrutiny panel for the costs of employing external workers.
Cornwall Councillor Alex Folkes, a member of the police and crime panel charged with holding Mr Hogg to account, said the bill was "quite incredible".
"Whilst other commissioners have appointed deputies on £60,000 salaries, our local commissioner has instead spent even more on consultants," Coun Folkes said.
"These have included 'advisors on organisational change' and 'strategic human resources services' despite the very limited amount of change in staff compared to the old police authority.
"In total, the amount spent in the six months since November is £235,925.62.
"Of course, Cornwall Council is not a paragon of virtue when it comes to spending on consultants and agency staff.
"But the new administration has already set in motion a programme to cut these amounts and, where possible, transfer agency staff who are working for the authority on roles that will always be needed on to cheaper full-time contracts. Our spending in this area is going down.
"Like the council, I can understand that the police commissioner might well need agency staff or expert outside advice from consultants from time to time. But these amounts – in just six months – are quite incredible."
Mr Hogg replaced the former police authority which was made up of councillors from local authorities as well as independent members.
All eyes are on whether Mr Hogg's office costs more to run. The annual bill for the authority was about £2 million. Details of all the spending on consultants have been published on his website. They include a monthly payment of £1,660 to his advisor Jan Stanhope, a former member of the police authority.
Sue Howl, chief executive of the Office of the Police and Crime Commissioner (OPCC), said: "We are completely transparent about our spending and the cost of consultants and agency staff has been published for public viewing on our website.
"Our budgets have also been subject to examination by our scrutiny body, the police and crime panel, since November 2012. The transition between police authority and OPCC has involved a great deal of new policy and governance work and it was only right and proper that we brought in, for a limited time, people with specific expertise in some areas.
"While we do not have the resources, or need, to create full time roles at this level, the processes needing to be put in place so that the police and crime commissioner could fulfil his statutory duties, required extra capacity in the period before the election and into 2013."
She added: "We are conscious of making considered and efficient use of resources, and not increase costs significantly from the police authority spending. However the OPCC has a much wider remit and we must be realistic about some of the costs involved for the commissioner to perform his duties effectively."
