Can they come close to matching the SSE Broadband offers for fibre?
SSE have up to 38Mb for £10 (half price for 2 years) plus £12 line rental, and up to 76Mb for £12.50 plus £12 line rental. The minimum contract is 18 months.
(Southern Electric is an SSE brand)
There are also some substantial cashback offers via TopCashback on top of this.
An order for the SSE service has already been placed... but they don't appear to act on it for at least 14 days.
