I've just discovered that BT might impose a
Broadband Cease Charge, where the service is ended in certain circumstances. At present it is £31.
Quote:The Broadband Cease Charge is a compensatory charge raised in certain circumstances to cover the additional cost to BT of the work required within an exchange to recover equipment and amend records when a Broadband line is ceased.
When will the charge be raised?
This charge will be raised should you:
Switch to a Cable provider
Switch to another Broadband provider without following the standard transfer process*
Cease your Broadband completely
Cease your Broadband and move outside of the UK
When won't the charge be raised?
This charge will not be raised should you:
Live in an exchange area with no cease charges (use the checker to see this)
Move home and you re-connect to BT Broadband via the homemover process
Move home and we are unable to provide the service at your new UK address
You are ceasing service due to bereavement or severe illness
[…]
* This requires you to contact your new provider.
This,
according to Plusnet which makes an equivalent charge, is because BT Wholesale levy a fee "to cover the cost of removing broadband from a phone line."
I took it as read that whilst under contract the subscriber would have to pay to leave, but assumed that once the term is up that ending the service would be at no charge.
There is an article from Which? on this:
Hidden broadband ‘cessation’ charges. According to it, Sky doesn't impose such a charge, but BT, Plusnet, EE Broadband, John Lewis Broadband and Utility Warehouse do. So it seems varied as to whether ISPs absorb the charges made to them or not.
