About £68 a month - but that’s for 900meg down and 100 up. Working from home with a couple of others in the house it does come in handy as the low latency gives me a smooth experience making work phone calls over my Amazon remote desktop.
Annoyingly alongside my fibre optic broadband I have to pay separately for a copper phone line that doesn’t even have a phone plugged into it but this is common for everyone in the UK, even the cable provider (there’s only one, Virgin) charge less for broadband if you take it with a phone than without - not sure why as I use my mobile!
