The hub5 is free, do you mean how much is broadband? If so it depends if you are in or out of contract and whether you have negotiated a deal. Speak to the options team on 0800 800030
There's generally no charge for a hub supplied as part of a BT package, though you'll be liable for one if you cancel the service before the initial minimum term expires. Once that's up the hub becomes your sole property with no conditions.
That looks like too much, suggesting that you're no longer within a minimum term and accordingly paying full tariff prices. Your bills should show what the £60 comprises.
The Options Team on 0800 800 030 should be able to come up with better prices in exchange for you committing to a further minimum term. Try negotiating with them.
You need to check with the person you are going 50/50 with to see what BT package and extras you are paying for although it sound like they are conning you into subsidising their BT TV package.
