Car parking charges for patients and visitors will return at the Boston and Grantham hospitals from next week after problems with the new system installed in November.
However, due to a technical glitch parking will continue to be free for the public at Lincoln County Hospital until later in the month.
ParkingEye took over the parking facilities in late November at Lincoln, Grantham and Boston hospitals, but faced issue with the ANPR cameras and payment machines.
People were confused about the system which required them to remember their full registration numbers, and queues formed as machines failed at all three sites in early December.
Fines for overstaying were then cancelled and then ULHT decided to waive all parking fees until all the issues were sorted.
Parking charges for the public will start again at Pilgrim Hospital in Boston on Tuesday, January 8 and at Grantham and District Hospital on Wednesday, January 9.
Due to a delay in the installation of additional telephone lines, to improve the signal between the new ANPR cameras and the pay machines, parking will continue to be free for the public at Lincoln County Hospital until later this month.
Once the charges are reintroduced, visitors parking at Lincoln, Grantham and Boston hospitals will need to pay at the end of their stay by entering their car registration number at one of the pay machines or by using the good2go website.
Director of Estates and Facilities at ULHT Paul Boocock said: “Over the last few weeks we have been working with our car parking provider to improve the signal between the ANPR cameras and the pay machines.
“We have experienced a technical delay at Lincoln County Hospital and we will let people know when we are ready for the parking charges to be reintroduced.
“Most of the additional payment machines have been installed, along with all of the extra lighting and we are still putting up shelters around some of the machines. We will also have additional staff on hand to help when the charges are reintroduced at each site.
“I’d like to thank everyone for their patience and support over the past month and also apologise for any inconvenience it has caused.”
