If you sell online to consumers, this applies to you.
The Distance Selling Regulations (DSRs) change in June. They extend the cooling off period from 7 to 14 days but also give you the right not to refund until you have the goods back and you can deduct from the refund if the goods have been used (hurrah!).
If you use a telephone contact number it now has to be a basic rate one - 01, 02 or 03. (Or a mobile number, but that's not a good idea for other reasons - it makes you look small and amateur, unless you're a trade like a plumber.).

Consumer Rights Directive
We would like to take this opportunity to remind everyone that, effective from 13th June this year, any business that provides a contact number for their consumer customers must provide a ‘basic rate’ number instead. Essentially this means that consumers must be able to contact a business with which they have a contract for the same rates as they can call friends and family. The business should not earn revenue from the chosen contact number either. Therefore these businesses need to provide a geographic number (01, 02 or 03) or a mobile number. Any revenue share or premium rate (e.g. 09, 084, 087, 070) will not comply with this regulation.
For full details please see the guidance given by the Department for Business Innovation & Skills
There are other bits and pieces in the new regs that might apply to you like no more auto-ticked boxes and 30 day delivery period, so it's best to read them through.
We can help if you need another number ;-)
