Does mothercare?
There’s a pdf of a citizens advice bureau guide to guarantees here. Having a look seems to indicate that the conditions of guarantees you don’t pay extra for are at the discretion of the seller, nevertheless the terms of the guarantee should be available for you to see, so it may be that you should request a copy of the conditions from Mothercare. It may prove they are abiding by their own conditions. Bear in mind you still have the standard consumer rights regardless of the guarantee.
