I see Freeola also have a monthly FTTP offering, no idea of the quality of. £47 a month for 900Mbps with static IP (after the monthly £12 discount).
Checking the wording, they describe the discount as "[with] every Broadband connection, we'll give you £12 back every month, to spend on a pick 'n' mix of the services you want." This suggests you pay 58.99 but they give you a £12 credit each month to spend on their other services (hosting, etc).
