Many Brits are unaware that they could be owed refunds if their supermarket delivery is late.

Consumer group Which? has recently shared that if you've paid for a "special delivery" or your order arrives at your door "later than agreed" you can claim back delivery costs.

Speaking to Sky News, Scott Dixon from Complaints Resolver said that it falls under Section S49 of the Consumer Rights Act 2015.

That act reads: "Every contract to supply a service is to be treated as including a term that the trader must perform the service with reasonable care and skill."

Mr Dixon added that a late supermarket delivery is seen as a "breach of contract" under the 2015 act, sharing: "You paid for a time-specific delivery as part of the contract you entered into.

"You could request a refund of the delivery charge as the time-specific part of the contract constitutes a breach and has not been fulfilled."

How you can get your money back if your supermarket delivery is delayed 

He went on to say that if your supermarket delivery is late, you should contact the dedicated customer service team at the store and request a refund.

However, he adds that you should be "nice about it" adding that "you are more likely to elicit a better outcome that way given the value involved."

Sky News spoke to major supermarkets and Tesco said that they judge refunds in this situation on a case-by-case basis, adding that customers should contact their customer service team.

Asda said that they always aim "to deliver goods within the delivery slog agree with the customer".

But, the brand added that if a supermarket delivery is received outside of the time slot, they will let customers know that they can request a refund.

Morrisons and Ocado both said that they handle refunds on a case-by-case basis but will contact customers.

Waitrose said: "In the event of a delay, the shop makes every effort to contact each customer directly in advance of their delivery to explain the situation and provide an updated ETA.

"If the customer is no longer able to accept the delivery, we work with them to reschedule it at a time that suits them.

"While delays are often beyond our control, we assess each situation on a case-by-case basis, and Partners can offer a gesture of goodwill when customers are inconvenienced."
