For those of you using satnav the correct postcode is AL4 0NP and if you are driving there yourself please see the following -
Firstly it is suggested that you turn off at Junction 22 on the M25 rather than Junction 23, then follow signs for Colney Heath and turn left at the roundabout in the village into the high street. Ground entrance is next to the school is on the right after half a mile.
