as a customer of First Utility, I've recently been informed that's they've now started offering broadband packages.
Their packages look attractive and well priced... 76 down / 20 up for £34.99 per month including line rental. (and other packages available too)
I gave them a call to find out a little more, but there are a few watchouts...
The router is Technicolour TG588v2 (the same one used by Plusnet, I think), and not all that great for heavy users.
It's an 18 month term
Importantly, though, it's tied explicitly to your energy account. If you leave them as your energy provider, they terminate your broadband and you have to pay the relevant early termination fees.
Perhaps this isn't that uncommon, but not something I've come across before, so thought it worth flagging in case anyone else was looking at them.
