CRAIG CURRAN celebrated a hat-trick in an emphatic win for the Blues.
Ben Mills put Chester 1-0 up after just five minutes when he connected with a right wing cross from Dave Hankin.
Preston referee Lee Metcalfe angered the visitors in the 16th minute when he had second thoughts about awarding a penalty after initially pointing at the penalty spot. He over-turned his decision after consulting his assistant.
Bishops Stortford skipper Reece Prestedge equalised in the 28th minute with a close range header from Ricky Sappleton's cross.
Substitute Craig Curran fired home a 12 yard shot to put Chester 2-1 in front after 62 minutes, just three minutes after replacing Hankin.
The visitors were reduced to 10 men in the 70th minute when Lewis Spence was shown a red card for a hesad-butting offence on Curran.
And Chester made it 3-1 in the 73rd minute when Curran smashed home after Mills' shoit had been parried by Carter.
Curran completed his hat-trick when he rifled a shot into the roof of the net in the 85th minute.
