Did a ze test and it was more than adequate, I've just finished rewiring the place, it was only when installing a fitting that we noticed/kept getting shocks. there are a couple of those 28w 2d fittings that I've installed, could it be anything todo with the control ballasts within these? will do a wandering lead test tomorrow, thanks for the advice

Had a lad working for me many years ago that could walk up and down a few times then point his finger near the switch and get a spark to jump across to it told one customer the problem was down to the cheap (£4k) carpet he had bought didn't go down well

Static can build-up in your clothing, it's not all to do with carpets and other floor coverings. Static can be a real bugger to get rid of at times too!!
 
Easy way to test if its static.. Touch the switch to discharge, then without moving your feet touch it again, you shouldn't get a shock the second time

If you check out the causes of static you will find that you can generate a few K volts just by waving your arms in the air !.

Isn't that why you don't see many Traffic Wardens directing traffic any more as they could just point a finger at a car and sent 1000s of volts shooting out of the end of their finger towards anyone who abused them?

Remember to check what the "victim" is wearing ie tracky top and bottoms
 
I was changing emg lights in a residential home a few months back . i was getting a healthy sock when pressing the down button on the lift. So I walked about scuffing my shoes on the floor then holding a 8w lamp touched the lift and the lamp lit every time. Made us all chuckle
 
The most likely explanation is that they are buildig a static charge,
then they touch some thing that is earthed ( metal switch plate )
and thus receive a tingle.
The solution is to change the metal switshs to plastic
so no more earthing thru switch plate.
Or change the carpet !
