Hi Mark. I don't think there's a BB provider that does exactly what you want, and the I think reason is that the provider is charged by BT for installation and the use of the line. Also any supplier with a short contract will charge the full setup cost up front. The nearest I know of to what you want is Metronet. They will charge the installation fee, and you supply your own modem. They will then charge £10 a month for up to 200M download and a small incremental amount over that. If you cancel the contract, you will have to pay the setup fee again, so that wouldn't be a good option unless there was a long inactive period. The minimum contract period is 3 months.
