The Bilston Glen centre, which was at the centre of the M9 tragedy controversy, took on the work of other centres in Stirling and Glenrothes in April 2015. Opponents claimed that the centre had been inadequately resourced from the start - and it has now emerged that £350,000 was paid in overtime to fill gaps in the rota to handle increased demand.
However, Police Scotland insist that their total overtime costs came down after Stirling and Glenrothes were axed, while service delivery to the public has improved.
John Yuill and Lamara Bell died in 2015 when the car they were travelling in crashed off the M9. It took three days for officers to arrive at the scene despite a call to the force’s 101 number.
Problems with logging calls at Bilston Glen were blamed, where staff complained of a lack of resources and insufficient training.
The figures unveiled by the Conservatives show that overtime payments at the centre reached £289,728 in 2015/16, and £60,852 so far in 2016/17.
Scottish Conservative shadow justice secretary Douglas Ross said some overtime payments will be necessary.
But he added: “The sheer scale of these points to a major problem with staffing and resources there.
“If the Scottish Government had ensured these facilities were properly staffed to begin with, there wouldn’t be a requirement for additional payments of this magnitude. This is something the Scottish Government needs to get under control as a matter of urgency.”
But Chief Superintendent Roddy Newbigging, of Police Scotland, said overtime costs for Bilston Glen, Stirling and Glenrothes in 2014/15 were £398,275 - and fell by about £100,000 the following year.
He added: “Last month HMICS reported that the service which the public receives has improved, with 93% to 97% of ‘999’ calls being answered within 10 seconds and 91% to 100% of non-emergency 101 calls being answered within 40 seconds.
“Therefore, we are now providing an improved level of service at a much reduced cost to the public.”
