With any contract or sale which is concluded in this way, you must be sure you have been presented with clear written notice of your 7 day right to cancel, at or before the time the contract is made. If you have not, the contract is legally unenforceable. This notice, which cannot be in the form of small print, or otherwise disguised, must also provide a cancellation form and advise you on how and to whom a notice of cancellation is to be made.
Similar to the Distance Selling Regulations, you are able to cancel the contract at any time within 7 days from the time the written notice (of your right to cancel) was given to you by the trader. You can either use the cancellation form which should have been provided, or a simple written notice, as long as it is clear of your intentions. With regard to sending your notice to cancel by post, as long as it has been posted before the end of the 7 days, it doesn’t matter when it is actually received. For this reason, it is always advisable to send it recorded delivery.
