Leave the motorway at junction 4. Reset your trip meter as you pass the top of the M25 Junction 4 exit when travelling anti clockwise. Proceed along the A224 for exactly 3 miles, crossing one roundabout and 3 traffic lights. At the 3 mile point just after a parade of shops turn left into St Andrews drive. St Andrews drive runs straight for 30 metres before making a right turn and becoming The Greenway. Follow The Greenway until the road makes a left hand turn followed by a right hand turn at which point it becomes Bridge road. Atomwide is the 1st entrance on your right.
Come out of London via the Old Kent Road, Lewisham, Lee Green and onto the A20. Follow the A20 to Sidcup and take the first exit AFTER Sidcup turning right onto the A224. Follow the A224 to the set of traffic lights AFTER the railway bridge, WATCH OUT for the cameras on the set of lights before the railway bridge. Turn right at the set of lights after the bridge up Poverest Hill followed by an almost immediate left into Bridge Road. Atomwide is in the 2nd industrial unit entrance on your left.
