Two of us have said this;
"Your contract is with the seller, not the manufacturer. Any warranty offered by the manufacturer continues to exist but that is separate to your statutory rights.".
I've quoted the other person's. That person got no votes, up or down. I got a down vote. For stating the simple truth. In the UK you have a contract, a civil contract, with the supplier. When that contract fails, because the supplier ceases to trade, you become just another creditor. And since the hierarchy of creditors runs, insolvency practice, government, preferred lenders (banks etc), everyone else there is little chance of getting redress from the insolvent supplier. You join the back of the queue.
Unless you have a manufacturer's warranty that gives you the same protection ( it's unlikely to offer yo a refund). You can claim on a credit card against the card issuer if you paid for part or all of the item by card.
