Leave the M25 at junction 10 and join the A3 southbound towards Guildford/Portsmouth. On approaching Guildford, ignore the first exit to Guildford and the Leisure Centre as this road gets very busy and instead continue on the A3 (passing the new offices on the left) and take the next exit left, signposted Hospitals, Onslow Village, Cathedral etc. At roundabout take the third exit, signposted to Research Park, then take the first exit at next roundabout to go back on A3, heading towards London. Take the next exit left, signposted A25 Dorking, move into righthand lane and go under the A3, taking the Guildford Business Park exit from the roundabout. Once in the Business Park, turn left and the Philips Centre building is a short distance along on the left.
There are parking spaces at the offices for both visitors and staff.
