Normal laminate is non-conductive. So no different than using a piece of glass.
But instead of buying the expensive ESD top, check out the cost for getting a suitably sized 2 layer rubber ESD mat instead. I mention this as I find the rubber mat is superior to ESD laminate as it protects the table surface from dings, dents, scratches, and most importantly, thermal damage from soldering equipment.
And as a general rule, this tends to be less expensive as well. Just not so sure about UK/EU sources though.
However, there's a Canadian seller on eBay (
canvuO_O) that will do custom sizes and ship internationally*. His pricing is the best I've ever seen. To put his pricing into perspective, a 30"x60" mat shipped to the US would run $78.50 total ($58.50 for the mat & $20 shipping).
So sending an email in regard to total cost to the UK would definitely be worth it IMHO.
