One of the most important implications of the distance selling regulations is a cooling off period of 7 working days during which you have the right to cancel and get a full refund.
The supplier must provide you with details of your cancellation rights, any duty to return the goods should you cancel, and whether you will have to pay for this.
If the work started with your permission and the supplier has not provided you with the compulsory pre-contractual information prior to their starting, you may still have your right to cancel and get a full refund even though the work has been completed!
The supplier must provide you with specific information related to your rights and their obligations under a distance selling contract.
You may be required to pay to return the goods, but you must have been informed of this as part of the pre-contractual information.
if the goods are faulty, then under Sale of Goods, the supplier will always bear the cost of returning them.
Unless you are required to return the goods, and you were informed of this, your only obligations are to make the goods available for collection and to take reasonable care of them while they are in your possession. Where the supplier has made provision to collect the goods, this duty of care expires after 21 days, but where you have agreed to return the goods, your duty of care continues until you do this and could be for as long as 6 months.
Under a distance selling contract, a supplier cannot make refunds subject to the goods being returned unopened in their original packaging.
