Aldi is set to create 2,000 new jobs next year as part of a £1.3billion investment drive that will see 100 more supermarkets open up by 2023.
The German discounter made the announcement, which will run for two years, as bosses revealed sales soared 10.2% in the UK and Ireland in 2020 to £12.3billion.
Aldi, which is privately owned, added the number of customers during the period increased from 17.6million to 17.8 million, although pre-tax profits fell 2.5% to £264.8million.
Giles Hurley, chief executive for Aldi UK and Ireland, said: "As well as delivering record sales, we continued to invest for growth, deploying over £600 million in stores and distribution centres across the UK.
"This helped to create thousands of much-needed jobs and support for British farmers and manufacturers.
"Whilst the cost of responding to the pandemic dampened profits, our decision to return business rate relief was the right thing to do."
Aldi repaid the business rates saved from the Government's scrapping of the tax during the pandemic, following similar moves by Tesco, Sainsbury's, Morrisons, Asda and Lidl.
Looking forward, the supermarket announced its click and collect services have been rolled out to 200 stores, offering shoppers the chance to order online for the first time - although home deliveries are still not available.
A new £1.8million checkout-free store has also opened in Greenwich, London, it said, although it is still being trialled amongst staff.
The rollout will allow customers to simply shop and walk-out without queuing up to pay for their groceries.
To use it, customers need to download an app on their smartphones. When they leave the shop they are charged automatically and get a receipt emailed to them.
Currently the system is only being used by the supermarket's employees, not customers.
But if the system works it will be rolled out to the public, the supermarket said.
As part of the £1.3billion investment over the next two years, bosses said around 100 new stores will be added to the 920 sites already operating.
The expansion of its logistics infrastructure includes a new 1.3 million sq ft site in Leicestershire.
There was no initial mention by Aldi of any supply chain issues or suggestions of price inflation, although the company said it had reduced prices to the tune of £238 million last year.
