For most things bought online you don't need a reason, a fault, or the shop's permission to return them. You have 14 days from delivery to cancel, and they must refund you, including basic delivery.

This right has real carve-outs: personalised items, sealed goods unsealed after delivery for hygiene reasons, perishables, digital downloads you've started, and a few others. If yours is standard goods in resaleable condition, though, the right is close to absolute.
And if the seller never told you about your cancellation right at all, the window can extend by up to 12 months. Silence costs them.
