@Suzanne Welcome to the forum.
I assume that Talk Talk UFO is their full fibre product? Depending how much you pay this can be much faster than Plusnet can currently offer. To see what you can get put your phone number in here and see what the VDSL range is. https://www.broadbandchecker.btwholesale.com/#/ADSL
