Things You Cannot Return When Buying Online

There is no right to cancel for: goods made to your specifications or clearly personalised; goods liable to deteriorate or expire rapidly; urgent repair visits you asked for; newspapers and magazines (except subscriptions); public auctions; goods whose price depends on financial markets; certain alcohol; and accommodation, transport of goods, car hire, catering or leisure services for a specific date. Sealed hygiene goods, sealed recordings and sealed software lose the right once unsealed (Consumer Contracts Regulations 2013, regulation 28). source

Most online and phone orders have a 14-day cooling-off period, but goods that are clearly personalised or made to your specification are excluded. Made-to-measure items for non-standard sizes are an example. source

The usual 14-day cooling-off period for online and phone purchases does not apply to tickets for leisure events that state a specific date or time period, such as concert tickets. Once you have bought, you generally cannot cancel just because you changed your mind. source

Online traders must state payment and delivery costs clearly and offer a 14-day cooling-off period, though you may have to pay return postage unless the item is faulty. source

Goods you buy from a business must be as described, of satisfactory quality and fit for their purpose (Consumer Rights Act 2015). Your contract is with the seller, not the manufacturer, so the seller is the one to complain to. source
