From 13 June 2014 the Consumer Contracts Regulations 2013, which implement the Consumer Rights Directive in UK law, came into effect. This replaces the Distance Selling Regulations and Doorstep Selling Regulations.
The regulations apply to items bought online, at a distance, or away from a trader's premises (for example, at home or at work). They also make it an obligation for traders to give consumers certain information.
Some key points:
Your right to cancel an order starts the moment you place your order and ends 14 days from the day you receive it.
Your right to cancel a service starts the moment you enter into the contract and lasts 14 days.
If you want to download digital content within the 14 day cancellation period you must agree to waive your cancellation rights.
Companies are not allowed to charge you for items they put in your online shopping basket or that you have bought as a result of a pre-ticked box
