Built from real receipts, not a survey

What the shopping actually costs where you live

Every week, households here scan their receipts. We turn those lines into a price per kilo and per litre, pool them by postcode area, and publish the middle price. Not an average of the country six weeks ago: the shop down the road, this week.

The basket across the country

Nobody near you has shared enough of a shop yet to price a whole basket. Scan your next receipt and you help build the figure you came here for. Scan a receipt if you would like to help.

Item by item

The middle price paid, not the cheapest and not an average. One person buying something unusual cannot move it.

Nothing has cleared the bar yet. A price is only published once at least four separate households have bought that item, so that nothing here can be traced back to one person's shopping.

The basket is 15 everyday items, weighted by how much of each a typical week contains.

Seen a price? Send it in

Receipts only show what people bought. If you spot a shelf price worth knowing about, add it and it goes into the figures for your area. Every one is checked against what receipts already say for the same thing, so a mistyped pack size cannot move a price.

Join free to add one. It takes an email address and nothing else.

  • Type the shelf price for one pack, and the pack size exactly as the label writes it.
  • Every price is checked against what receipts already say for the same thing.
  • One that does not match costs you nothing and is simply not counted.
  • Nothing you send is shown to anybody with your name on it.

Scanning a receipt is still the quickest way to help: it adds every line at once.

Take the data

A figure nobody can check is not worth publishing. Every published point is downloadable, free, for any use including a commercial one. Please say where it came from.

How it is worked out

  • Every price is a price somebody actually paid, off a till receipt, not a shelf survey or a supplier's list.
  • Everything is converted to a price per kilo, per litre or per item, so a pack that shrinks shows up as the price rise it is.
  • We publish the middle price, after trimming the extremes, so one odd line cannot move it.
  • Nothing is published until at least four separate households have bought that item, so no figure can be traced to one person's shopping.
  • Your receipt photo is still deleted within fifteen minutes. Only the anonymous lines survive.

Questions about the price index

Where do these prices come from?

From till receipts that households here have scanned. Each line is matched to a standard item, converted to a price per kilo or per litre, and pooled with everyone else's. Nobody is surveyed and no shop supplies us with a price list, so what you see is what people are really paying at the till, including whatever discount they got.

Can anyone work out what I paid?

No. A price is only published once at least four separate households have bought that item in that area, and what is published is the middle value of all of them, not a list. Your receipt photo is deleted within fifteen minutes as always; only the anonymous line survives, and it carries no name, address or card number.

How is this different from the inflation figure on the news?

The ONS figure is a national average, collected by price collectors visiting shops, published several weeks after the month it covers. This is your postcode area, from what people actually paid, updated every day. The two answer different questions, and it is worth watching both.

Why does my area show the national figure?

Because too few people near you have shared a shop yet, and a price built from two receipts would mislead you rather than help. You will see your own area's figure as soon as enough neighbours have scanned one, and scanning yours is the fastest way to get there.

Can I use this data?

Yes, for anything, including commercially. Download the CSV, use it in a report, a news story, a dissertation or an app. All we ask is that you say where it came from and link back so people can check it themselves.

What is shrinkflation and how do you spot it?

It is when a pack gets smaller while the shelf price stays the same, so you pay more per kilo without noticing. Because we record the pack size alongside the price, a change shows up as soon as enough receipts show the new size. We only name one when both the old and the new size have been seen on several receipts.
