The Tesco store in Purley, Surrey has had external area lights on 24/7 for the last two years (at least!) and until now has denied all responsibility, blaming the local council and even the Highways Dept!

Finally, last Bank Hoiliday Sunday, I was told in-store that they were 'awaiting a sensor' to be delivered and installed.

Are there other Tesco stores with similar energy wasting situations?

I will keep watch on this total waste of energy - some 10MW-hr per year by my estimate!
