Take the M11 north until it merges into the A14 west towards Huntingdon.
Take the Bar Hill turn off and follow signs to Earith. When you enter Earith take the right turning after the phone box in the middle of the village towards Somersham.
Follow and turn right at a left hand bend towards the Industrial Estate (signposted). Follow road for approx 1/2 mile and as the road bears left you will see a brick sign saying ‘Earith Business Park’, turn right immediately before this and at the end of the road on the left is KLM.
