Cancellation Calculator

Estimate how much you could be charged if you cancel a telecoms contract with a minimum term early. The result appears straight away — no email and no account needed.

If you renewed your minimum term, enter the date the new minimum-term period started.

Usually 12 or 24 months.

Is this your first minimum term or a renewal?

Renewal: a new minimum-term period on the same contract, for example when changing tariff or accepting a new offer.

The amount stated in the contract as the advantage or benefit for accepting the minimum term (for example, discounts or free installation).

Did you receive subsidised equipment linked to the contract?

For example, a mobile phone or other equipment given free or at a discount because of the minimum term.

This calculator estimates the maximum charge for an early cancellation at the customer's initiative, where there is no legal or contractual reason allowing you to cancel free of charge.

How it works

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.

  • Your data.

    The calculation happens only in your browser: we don't store the amounts you enter or link them to you.

  • If you decide to go ahead.

    Under “Start my case” you describe what happened, create your account and choose the option that suits you. You only pay at the end.
