Hopefully this helps to clarify:
The charge can apply to any customer who has a broadband cease placed on their line.
Generally, the main reasons for broadband ceases are:
A broadband account is cancelled (without switching providers)
Switching providers without a MAC key
The telephone line used to provide broadband is cut off
Cessation charges don't apply if:
You use a MAC key to switch to another provider (this is called a migration)
You're a customer without a contract on any of the following products:
Plusnet Essentials
Unlimited
Unlimited Fibre
Unlimited Fibre Extra
