Martin Lewis of Moneysavingexpert.com, external explains what you need to do to get your money back if you had a Monarch booking.
If you paid with a credit card for a transaction worth between £100 and £30,000, he says you need to make a section 75, external claim under the Consumer Credit Act with your bank or card provider. The card company is jointly liable along with the merchant and although the process may not be speedy, "you should get your money back", Mr Lewis says.
If you paid with a debit card, the less well known "chargeback, external" protection applies. He advises consumers to ask for their money back because they will not get the flight they have paid for - and the process should be "reasonably speedy".
Those who paid with PayPal should also get refunds as the platform refunded customers of Lowcostholidays when it failed last summer.
