Lidl cheapest UK supermarket of 2020 - Which?

The consumer group tracked 45 own-label and branded products in eight major supermarkets for at least 100 days and found the German supermarket to have the cheapest offer.

German rival Aldi was only narrowly behind since the price difference between the German supermarket giants was just 34p.

Lidl came in at £42.67 versus Aldi on £43.01.

Asda came third, but by a margin of over £5 - at £48.71. Tesco was fourth at £53.30, followed by Morrisons at £53.61, and Sainsbury's at £56.38.

Most expensive were Waitrose (£68.69) and Ocado (£66.83).

Which? said there was a large difference between certain items in the cheapest supermarket and the most expensive supermarket. Waitrose's own-label cooked and peeled prawns were £4.60 on average, when the equivalent was £1.99 at Lidl.

Lidl now has about 800 UK stores and Aldi around 900.

The only disadvantage for the German supermarkets is that neither have their own in-house delivery services in the UK, however Aldi is sending food parcels out to vulnerable people during the Covid crisis.
