What you need to know about the calculator.
How the calculation works.
For contracts with a minimum term that started or was renewed on or after 14 November 2022, the charge is the lower of two amounts: the part of the benefit still to be recovered, in proportion to the minimum term remaining, and a percentage of the remaining monthly payments (50% in the first year and 30% in the second; 30% for a renewal without a new installation). For earlier contracts, it is the benefit in proportion to the time remaining and, for a renewal without a new installation, also the 30% cap on the remaining monthly payments.
What it isn't.
It doesn't assess whether you can cancel free of charge, it doesn't include equipment charges and it isn't a legal assessment of your case.
