We have now replaced Tesco Price Promise with our new instant price matching scheme Tesco Brand Guarantee.

We know you want great value for money and the best deals, but that you don't want the hassle of shopping around. That’s why our Price Promise price matches the products you love across fresh, brand and own label.

How Tesco Price Promise works

When you shop at Tesco, we’ll check your basket against the prices at Asda, Sainsbury’s and Morrisons. If your comparable grocery shopping would have been cheaper there, we’ll give you a voucher for the difference (up to £10).

If you shop in-store, we’ll give you the voucher at the checkout, or if you shop online, we’ll send you an e-mail after your delivery has arrived.

To qualify, you’ll need at least 10 different items, including one comparable grocery item in your basket.

Where we get the prices

Asda – we take prices daily from the Asda.com grocery website

Sainsbury’s – we take prices daily from the Sainsburys.co.uk grocery website

Morrisons – We use an Independent agency to visit Morrisons’ stores twice a week, as this gives us a wider representation of comparable products than is currently available from the Morrisons.com grocery website

We use an independent agency to check the prices for us.

How we match the prices

Branded Products

Brands are easy to match, as long as Asda, Sainsbury’s and Morrisons* sell the same products and pack sizes as we do.

Example Soft Drink - 330ml multi packs

  Tesco Asda Sainsbury's Morrisons
Individual can
8 x 330ml
12 x 330ml
15 x 330ml
24 x 330ml
30 x 330ml
We compare against Asda, Sainsbury’s and Morrisons, because all 4 sell individual cans of the product
We only compare against Asda and Sainsbury’s, because Morrisons don’t offer the 8 x 330ml pack size
This pack size wouldn’t be in your basket, because it isn’t offered in Tesco stores
We aren’t able to compare this item, because it isn’t offered by Asda, Sainsbury’s or Morrisons

For illustrative purposes

Own label Products

It can be tricky to compare own label products – so we use quite a few guidelines to make the comparison as fair as possible:

Similar Items

The main guideline is that we only match similar own label products. Essentially, the products need to meet the same customer need – or be used by customers for the same purpose:

For example – we don’t treat toilet paper as being ‘similar’ to kitchen towels, because the products are used for different purposes.

Comparable items

We match comparable own label brands:

For example – In most cases we match Tesco Finest with Asda’s ‘Extra Special’, Sainsbury’s ‘Taste the Difference’ and Morrisons’ ‘The Best’.

In addition to this rule, we’ll also look at inherent qualities, regardless of own label brands, in order to match as many products as possible.

For example, we might match Tesco Healthy Living chicken breasts with chicken breasts from Asda, Sainsbury’s or Morrisons, even if they don’t have a healthy own label.

Other considerations

To ensure that we match products fairly, we also take into account a number of other things:

  • Country of origin – think meat and fruit
  • Grade – for example, eggs
  • Ingredient mix – this is important in products like bagged salads
  • Packaging – for example, canned beer or bottled beer

Pack sizes

Pack size varies a lot across retailers. Even if a product is a good match on every other front, we won’t include it if the pack sizes vary by more than 10%. This is because it is impossible to make a fair comparison where pack sizes are significantly different.

Weighted Items

The price of some products is based on their weight. There are a number of varieties of items sold by weight.

  1. Loose Items – Priced per kilo e.g. Bananas
  2. Fixed Weight Packs – e.g. 400g of mince
  3. Variable Weight Packs – Priced per kilo but with no fixed weight e.g. 246g chicken fillets

In some rare cases, we might offer an item that has a variable weight, but Asda, Sainsbury’s or Morrisons* might offer a comparable product in fixed pack sizes. In such instances, we will be unable to compare the price of the two products.

Why some items can’t be matched

Our Price Team matches as many Tesco items as possible with Asda, Sainsbury’s and Morrisons. Even though we’ve been doing this for over 15 years, sometimes it’s just not possible to get a match. Here are some reasons why:

We’ve got a bigger range

Sometimes products that you can buy in Tesco aren’t available at Asda, Sainsbury’s or Morrisons, so we can’t match them.

For example, we sell Innocent 380g Vegetable Pots. Asda don’t sell Innocent Vegetable Pots, so we can’t compare the price with Asda.

It’s not possible to fairly compare difference sizes of the same product

Tesco and Asda, Sainsbury’s or Morrisons may stock the same product but in a different size, weight, volume or quality. If there is a material difference (we say 10% for pack size) then the products cannot be fairly matched, because we would have to estimate the comparable price:

For example, we sell an 8, 12 and 24 pack of 330ml Coca Cola. Asda sells an 8 and 30 pack. If you buy our 24 pack, we can’t compare the price with Asda.

Not every product is available online

The fairest way to get accurate prices for Asda and Sainsbury’s is to get them online. However, sometimes a product is not available online, so we can’t get a price to compare against.

For example, we sell chicken and sweetcorn sandwiches online, but Sainsbury’s only sell the equivalent sandwich in stores.

* Morrisons does not have stores in Northern Ireland. As a result, the Tesco Price Promise only applies to Asda and Sainsbury’s in Northern Ireland.
