Yes they do, HyperOptic, G.Networks and Cerberus use CGNAT by default most of the smaller ISPs in the U.K. too do that now ever the largest take on new customers on some packages mostly the bundles via CGNAT. That said the cost of a real IP address is £5 a month with HyperOptic and I think 40 or £50 a year with G.Network so it’s still cheaper than a VDSL connection despite being 15 times faster unless you are in the 200mbit areas of BT.
