PricewaterhouseCoopers (PwC) has been appointed as administrator and is continuing to look for a buyer.
Wilko stores will stay open for now, with no immediate job losses.
Here, we explain what this means for any outstanding orders, returns or gift cards.
Will I receive my online order?
Wilko announced yesterday that home deliveries have been suspended.
Click and collect orders are still being accepted until the end of 10 August.
We've asked PwC for more information about whether online orders placed before home deliveries were suspended will be fulfilled. We'll update this page when we hear more.
If you don't receive your online order, you'll need to write to the administrators for a refund.
Read more:Will my gift card or voucher be honoured?
Gift cards are being accepted in-store.
We recommend spending any vouchers you might have as soon as possible, as the administrators can decide to stop honouring gift cards at any point.
If this happens, you'll likely need to make a claim in writing to the administrators with proof of your vouchers.
Unfortunately there's no guarantee you'll get all of your money back, and it could take up to 12 months to process the claim.
Find out more:Can I return items?
Returns for purchases made prior to the retailer going into administration are still being accepted.
We've asked PwC for more information on how you should make these returns.
As with gift cards, the administrators could take the decision not to accept returns at any point, so it's important to take back any unwanted items swiftly.
