How we compare supermarket prices

Using data from independent price comparison site MySupermarket.co.uk, we calculate the average price (including special offers but not multibuys) for a trolley of popular branded items.

In January, we tracked the prices of 62 popular items, including Andrex Classic Clean white toilet rolls, Fairy Non-Biological washing powder, Hovis Soft White medium sliced bread, McVitie’s Ginger Nuts, and Tetley tea bags.

The links below take you to our reviews of each supermarket.

We’re unable to include supermarkets such as Aldi or Lidl that don’t sell branded groceries online, as our price comparison is based on this data. Click the links to find out how customers rate Aldi and Lidl for value for money.


Supermarkets make environmental pledges

The start of the new decade has seen supermarkets announcing plans to help tackle plastic waste and carbon emissions.

Aldi removes plastic applicators from tampons

The German discounter has made a commitment to remove all plastic applicators from its own-brand tampons, replacing with cardboard alternatives. Aldi says this will save over 14 tonnes of plastic a year.

Of course, it’s not just plastic tampon applicators that are a problem in a basket of toiletries. In a recent investigation, we look at how we can tackle our bathroom plastics recycling problem.

Sainsbury’s invests to achieve net-zero emissions

The big-four supermarket has pledged to invest £1bn towards its operations becoming net-zero emissions, and waste, by 2040 – 10 years ahead of the UK’s legal goal.

The investment will tackle carbon emissions in its own business and operations, plus working with suppliers to achieve their own net-zero commitments. It will use more renewable energy and switch all lighting in stores to LEDs by 2022.

The supermarket also announced plans to target water use, such as fitting stores with rainwater harvesting facilities and recycling water from ice at the fish counters as well as at onsite car washes.

Work on plastic packaging waste continues too – including a pilot of a deposit return scheme for plastic bottles, and a pledge to remove dark-coloured, difficult to recycle plastic packaging from own-brand ranges by the end of 2020.

Tesco to remove plastic wrapping from tins

Multipack tins from Tesco will soon be plastic-free, removing 350m tonnes of plastic from Tesco’s supply chain each year.

The supermarket giant has teamed up with canned food businesses such as Heinz and Green Giant, and the changes will be rolled out from March.
