How about Woodford Park Heliport (as featured in "Helicopter Life" magazine)
3/4 acre site in the Woodford Park Industrial Estate
1.5 miles east of Oulton Park VRP at the bottom of the Manchester low level corridor.

"Winsford Radio" 119.575, displayed on the grass.
There's a Sea Harrier parked on the grass.
I kept an eye out for it yesterday on the way down the LLC, couldn't see it though. You'd need to ring for accurate directions, although PPR is not required.
"...no fuel but a warm welcome awaits..."
