Sorry to take issue here but I don't think TW is quite as good here as your post, and quote, implies:
There is an initial setup fee to provide the bit of kit, payable by all users.

Anyone using the slower speed BB connections will pay a monthly fee too.

It's only the high speed services, where presumably there is a higher margin, that the monthly, but not install fee, is waived.

However yes, as ever, ntl work out an expensive option when comparing those higher speed options.
