The company, now Britain’s fifth largest supermarket, plans to invest £1.3 billion over the next two years (2022-2023) to boost its share of the UK grocery market.
The firm gave the update as it published annual results that showed how UK and Ireland sales increased 10.2% to £13.5 billion during the pandemic.
Aldi UK, which has over 920 stores, including 48 stores within the M25, and around 38,000 employees, is led by Giles Hurley.
It plans to launch the new roles, adding to 7000 permanent jobs it said it has already created over the last two years.
Other investments will see it add 100 more UK shops to the estate, increase its warehousing space, and trial a new checkout free store in Greenwich.
Although sales climbed in the year to December 2020, pre-tax profit declined 2.5% to £264.8 million.
The retailer said that was due to investment in pricing and “the cost of responding to the pandemic”. It also repaid business rates relief.
Aldi’s Hurley said: “We’re continuing to gain even more customers - with over 60% of households shopping with Aldi in the last year. By redefining the discount supermarket in the UK, creating more places and more ways to shop with us, we are excited to provide millions of new customers with access to Aldi’s award-winning quality and unbeatable value.”
