The £25 cease charge relates to cost from Openreach to Madafish for movement of broadband from BT to LLU or, a change of provider without a MAC code. The line staying with existing provider.
The grey area is whether a transfer can be made from BTW to LLU with a MAC code or, a LLU MAC is required. Have you read Madafish T and C's.
In any event I would have expected BE to pick up this cost.
From Madasafish TandC
10.7 If you terminate this Agreement at any time, and choose not to transfer your Broadband Service using a MAC code, you will be required to pay a cessation (cancellation) fee of £25.00 to remove the Broadband Service from your telephone line. This charge is applied to us by BT.
