St John's Northwood

Potter Street Hill, Northwood, Middx HA6 3QY. Tel 0208-866067

Minibuses: Minibuses can get through the width restriction without difficulty - but if in doubt use the A404 / Potter Street route.

Important Note: Some maps show Potter Street Hill connecting through to the Watford Road (A4125). This used to be the case but for some years now Potter Street Hill has been blocked off above St John's and so there is no access to Potter Street Hill from the Watford Road. Please, also, do not use the back entrance to the school through the Gatehill Estate as this is a private estate.
