In October 2008 there were changes to the law on buying from a salesperson in your home. Now in most cases, you have seven days to cancel a purchase worth over £35. In addition, your right to cancel should be given to you in writing by the trader. If you're not given this information, they can't hold you to anything in the contract.

If you decide to cancel, you must let the trader know in writing within 7 days of being told about your right to cancel. It is advised that you should keep a copy of your letter or email as proof of cancellation.

The Office of Fair Trading advises that you should think carefully before you agree to have any work done or goods delivered within 7 days, as you might have to pay if you then decide to cancel.

It is also advised that you don't agree to buy on credit without looking at other loans on the market which might cost you less overall.
