Sainsbury's review

Find out how hundreds of Sainsbury's shoppers rate its supermarket stores and online grocery delivery service in our review.
Which? Team

Sainsbury's opened its first store in London in 1869, and says it wants to build on its reputation for quality, range and innovation. But does it offer great-quality food, excellent service and value for money?

In the annual Which? supermarkets survey, almost 600 Sainsbury's customers rated the retailer on everything from queuing time to the quality of its food and value for money. 

This enabled us to work out star ratings for different factors as well as an overall customer score.

How fresh is the food in Sainsbury's deliveries?

We went undercover to find out how the supermarkets compare on delivering fresh food, using a team of mystery shoppers to order more than 1,000 groceries in the first – and biggest – comparison of its kind. 

During the investigation, our mystery shoppers took delivery of items from various supermarkets that were already out of date when they arrived, groceries that were within their use-by date but looked too manky to eat, and one item with a completely illegible use-by date.

Log in or join Which? to discover which supermarkets will deliver the freshest produce, and which ones could leave you with past-it produce that's dangerous to eat. 

How safe are Sainsbury's stores in the pandemic?

When we surveyed Sainsbury's shoppers in October 2020, 81% rated its in-store Covid-19 measures as good or excellent. Find out how this compares with the other supermarkets in our survey by visiting our guide to the UK's best and worst supermarkets .

At the time of publishing this page (Feb 2022), Sainsbury's said its checkouts, baskets and trollies are regularly cleaned by staff and there is hand sanitiser available as you enter and leave stores. Customers are asked to keep a safe distance from other shoppers and staff.

Sainsbury's says it has also increased the amount of fresh air circulating in its stores to improve ventilation.

Sainsbury's in the news

Sainsbury's has attempted to win and retain customers with its Aldi Price Match scheme, through which it claims to match the prices of at least 150 items against the discounter.

In November 2021, Sainsbury's introduced the 'just walk out' technology used in Amazon Fresh stores at its Holborn Circus store in central London. To use it, customers scan a QR code using their SmartShop app. Anything they take off the shelves is added to their virtual cart. They then scan the QR code when they leave the store and their payment card is automatically charged.

In October 2021, Sainsbury's cut its target to reach net zero carbon emissions by five years, to 2035. It also said it would be using 100% renewable electricity by the end of 2021.

In September 2021, Habitat, which is owned by Sainsbury's, was relaunched in Sainsbury's stores and online.

Sainsbury's plastic packaging

In April 2019, we investigated how much supermarket plastic packaging is recyclable. We ordered 46 of the most popular own-brand items from 11 major UK supermarket chains. We found that 55% of Sainsbury's packaging, by item, was widely recyclable at the kerbside.

We also looked at how accurately the items in our basket were labelled with recycling advice, and found that 71% of Sainsbury's packaging was correctly labelled. See how Sainsbury's compared with other supermarkets and find out more about supermarket plastic packaging.
