If the contract is cancelled during the minimum term, I understand that I am liable to the termination charge calculated at the sum of the monthly tariff charges which would otherwise be payable until the end of the minimum term. After completion of the initial minimum term, this contract will automatically renew for a Further 12 months minimum term annually. Once we have begun to provide the Service to you, you may end the Contract at any time by providing us with no later than 30 days written notice before the end of the Minimum Term or a Further Minimum Term. Should you end the Contract in this manner during the initial Minimum Term or any Further Minimum Term, we will require payment of all of the Charges, or any part of Charges not yet paid by you to us for the remaining duration of the Minimum Term or the Further Minimum Term, as the case may be. The security system is subject to reservation of ownership until the final monthly payment has been made.
