Sainsbury's review

Find out how more than a thousand Sainsbury's shoppers rate its supermarket stores, app and website in our Sainsbury's review.
Which? Team

Sainsbury's opened its first store in London in 1869 and says it wants to be the UK's most trusted retailer - but can it be trusted to offer great-quality food, excellent service and value for money?

In the annual Which? supermarkets survey, more than 1,000 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 when it comes to 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During the course of the investigation, our mystery shoppers took delivery of items that were already out of date by the time they were delivered, groceries that were within their use-by date but looked too manky to eat, and one item with a completely illegible use-by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 to the other supermarkets in our survey by visiting supermarkets compared.

At the time of publishing this page (Feb 2021), Sainsbury's had joined many other supermarkets in refusing entry to anyone not wearing a face covering unless they are medically exempt. It is limiting the number of people in its stores at any one time and has put queuing systems in place outside when they're busy. You are asked to shop alone to help with social distancing and reduce queues. 

The number of checkouts has also been reduced to keep people distanced.Customer areas, baskets and trollies are regularly sanitised by staff and there are cleaning stations so you can sanitise your basket or trolley, as well as your hands, yourself too.

Sainsbury's in the news

In an attempt to take on the discounters, Sainsbury's followed Tesco in launching an Aldi Price Match scheme in February 2021. It's promising to match Aldi prices on more than 200 of its own-label and branded products.

Also in February, Sainsbury's announced that it would be topping up the government's Healthy Start vouchers for low-income families with a child under four and pregnant women by £2 a week – the biggest top-up offered by a supermarket to date.

In November 2020, Sainsbury's launched a new 'fresh food market' concept at one of its stores with a market-style display of fruit and vegetables and a focus on seasonality, which it plans to roll out to other stores if customers like it.

In the same month it was announced that Habitat, which is owned by Sainsbury's, will be selling its products in Sainsbury's stores and will become its main home and furniture brand.

A proposed merger between Sainsbury's and Asda was blocked by the Competition and Markets Authority early in 2019.

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 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.
