Looking at the new parking tariffs in Hertford, it appears that the price of parking for 60-90 minutes has just doubled.
Previously the first 30 minutes would be free and then you paid 80p for the following hour.
Now, the free 30 minutes are included in (rather than in addition to) the 1 hour tariff, meaning a stay of between 60 and 90 minutes costs £1.60.
I can't see any announcement about this other than the statutory Traffic Regulation Orders and signs about a new tariff on the car park noticeboards.
Obviously one wouldn't expect the so-called local newspaper to pick this up but it seems to have passed everyone by, including local retailers and the Town Council
