Abbey Fields car park will be opened within days to bring in parking funds weeks earlier than planned.
Work to change the informal parking area into a Pay and Display site started last month in what was expected would run into the middle of October.
The area has been resurfaced and pay machines installed. Parking bays have also been marked out and once it reopens, wardens will patrol the site to enforce charges.
Cllr Dave Shilton, Warwick District Council portfolio holder behind the work, said the team was “delighted” to see it all ready to be reopened so soon.
“Work has gone according to plan and the car park should be reopened on September 27 which is earlier than expected,” he said.
“This work has been essential. We have to move with the times and maintenance was becoming very costly with potholes and problems.
“Now it will be visitors to the car park who will help cover those costs and not taxpayers.”
He said that maintenance to the site was coming in at around £10,000 per year.
He also explained that drainage problems had been addressed after fears of where surface water would go once the stone surface was covered - one of the major worries for those against the plans.
Water company, Severn Trent will remove excess water in pipes away from the area, rather than leaving it to drain into the lower field which had previously been the case.
But the transformation was not welcomed by all as many fear the loss of up to 20 spaces as bats are marked out, as well as for where residents with no parking provision outside their homes will leave their vehicles overnight without having to pay each day.
There was also outcry at the council charging people to park on an area which technically belongs to the people of the town to be used for recreation.
It is planned that council permits for residents will extend to Bridge Street, High Street, Fieldgate Lane and New Street.
Charges will not apply for the first two hours and then will be set in line with other district council car parks in the town.
