Various products on Tesco’s Aldi price-match scheme are not like-for-like matches with those of the discounter, according to an investigation by BBC’s Panorama.

Tesco Aldi price match

BBC’s Panorama programme has put Tesco’s Aldi price-match scheme under scrutiny

The programme found that items such as chicken nuggets, blackcurrant squash and chicken kievs contained less of their main ingredients compared with the Aldi equivalents, according to the investigation carried out in August this year.

Tesco’s chicken nuggets contained just 39% chicken, compared with 60% in Aldi’s version. Its chicken kievs were 44% chicken, while Aldi’s, by comparison, were 57%.

The discrepancies weren’t just in poultry, with Tesco’s chilli con carne containing only 15% beef compared with 27% at Aldi.

Of 122 Tesco groceries, Panorama found that 38 had at least five percentage points less of the main ingredient than comparative items at its discounter rival.

By comparison, 12 Tesco items contained more of the main ingredient than Aldi.

Tesco told the BBC that it “constantly reviewed the quality of its groceries and has clear processes implemented to make sure its price-matched goods are comparable to Aldi”.

The supermarket giant also said having a higher quantity of ingredient in a product did not necessarily make that item a higher quality.

Retail Week has approached Tesco for a comment.

While Tesco’s supermarket rivals Sainsbury’s, Asda and Morrisons all offer Aldi price-matched products, Panorama did not find clear evidence of any inconsistencies in their amounts of main ingredients compared with Aldi.
