I’ve decided to take the plunge and get WiFi at my place. When I checked a couple of months ago, I could have got £50 from Plusnet for signing up, it has now been increased to £75 (if you go through https://broadband.moneysavingexpert.com/?_ga=2.17575420.498532646.1592857793-1037780822.1592857793 )
Ok, I do have to pay £50 for a line to be installed, but I’m still £25 up. If you already have a phone line installed, you’ll get the whole £75!
It’s £18.99 per month for 12 months.
