The scheme, which was announced by Chancellor Rishi Sunak last month, is aimed at protecting jobs in the hospitality industry and encouraging people to safely return to dining out.
Restaurants, bars, cafes and other establishments who use the scheme will offer a 50% reduction, up to a maximum of £10 per person, to all diners who eat and/or drink-in on Mondays, Tuesdays and Wednesdays throughout August.
It can be used by diners who order food and/or drinks for consumption on the premises, however, alcohol is excluded from the offer.
Customers do not need a voucher as participating establishments will deduct the discount from their bill, and then be able to reclaim the discounted amount through an online service.
Claims can be made on a weekly basis and will be paid into bank accounts within five working days, however, businesses must wait seven days from registration to make their first claim.
"Our Eat Out to Help Out scheme’s number one aim is to help protect the jobs of 1.8 million chefs, waiters and restaurateurs by boosting demand and getting customers through the door," says Chancellor Rishi Sunak.
"More than 72,000 establishments will be serving discounted meals across the country, with the government paying half the bill.
"The industry is a vital ingredient to our economy and it’s been hit hard by coronavirus, so enjoy summer safely by showing your favourite places your support – we’ll pay half."
Those establishments that sign up to Eat Out to Help Out will receive a window sticker to show they are using the scheme and can also download promotional items.
They will also appear on the online Eat Out to Help Out restaurant finder tool, which has so far been accessed more than 3.3 million times according to the Treasury.
