From junction 11 of the M25, take the A320 for Woking and Guildford.
At the first roundabout, turn right. Follow signs for Chertsey,
passing straight across three roundabouts. At the next roundabout,
turn right, onto Hanworth Lane. Take the third entrance on the left,
into the Forum business area. Drumgrange is the last building on the
right at the end of the road.
