UK Grocery Prices: Tesco, Sainsbury's, Asda, Aldi

UK Grocery Prices compares supermarket prices from Tesco, Sainsbury's, Asda, Aldi and Morrisons in one dataset. Every product comes back in the same format: price, was-price, loyalty card price, unit price, offer text and end date, pack size, stock, category, rating, and a match key for lining up the same product across shops.

Search five UK supermarkets at once, read whole categories or whole shops, or price a shopping list at every shop and get the cheapest basket. Clubcard, Nectar and More Card prices come back as their own field, separate from the shelf price.

What is UK Grocery Prices?

UK Grocery Prices is a UK supermarket price comparison scraper for Tesco, Sainsbury's, Asda, Aldi and Morrisons. It reads the product data each supermarket shows on its own website and returns all five shops in one row format, so a Tesco row and an Asda row have the same fields and can sit in the same spreadsheet. It works as a UK grocery price API alternative: you send search terms, category links, product links or a shopping list, and you get clean JSON back.

The easiest way to try it: open the Input tab, keep the prefilled search semi skimmed milk with all five shops, and click Start. You get 20 products, 4 from each shop, in about 5 seconds.

What can UK Grocery Prices do?

• 🔍 Search five supermarkets at once: each search term runs in every shop you pick, and every row keeps its query and position.
• 🗂️ Read category pages: paste category links from any of the five shops; the Actor works out the shop from each link.
• 🏬 Read whole shops: Catalogue mode walks every grocery category of Tesco, Asda, Aldi or Morrisons.
• 🔗 Refresh known products: paste product links to re-price a fixed list, for example the products you track.
• 🛒 Price a shopping list: Basket mode matches each item in every shop, adds up the totals, and names the cheapest complete basket.
• 💷 Get every price: the shelf price, the was-price, the Clubcard, Nectar or More Card price, the unit price, and the offer text with its end date.
• 🥗 Add ingredients and nutrition: one switch adds the ingredients list and the nutrition table.
• 📈 Keep weekly price history: the Actor can store this week's prices in your account and add a priceHistory list once a product has two or more weeks.

On the Apify platform you also get scheduled runs, a full REST API, integrations with Make, Zapier, n8n, Google Sheets, Slack, and webhooks, and export to JSON, CSV, Excel, XML, or HTML.

In Basket mode each shop's line is saved as a row with type: "basketLine", and the key-value store record OUTPUT holds every shop's total, the matched and missing lines, and cheapestRetailer.

Basket API (Standby)

The Actor also runs as an always-on HTTP endpoint through Apify Standby. Send a shopping list and get the totals back in the same request, without starting a run:

curl -X POST "https://parsebird--uk-grocery-price-scraper.apify.actor/basket" \
  -H "Authorization: Bearer <YOUR_APIFY_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"items": ["2 x semi skimmed milk", "baked beans"], "retailers": ["tesco", "asda", "aldi"], "pricing": "live"}'

The body takes items (strings or {query, quantity}), retailers, pricing (live or snapshot), pick (cheapest or relevance) and useLoyaltyPrices. Each matched line at each shop is charged as a basket line.

FAQ

Which shop data is available for each supermarket? All five shops return price, was-price where shown, unit price, offer text, pack size, category and image. Tesco and Sainsbury's also return EAN barcodes. Tesco, Sainsbury's and Morrisons return loyalty card prices (Clubcard, Nectar, More Card). Aldi's UK site marks its products as not sold online and shows no ratings or barcodes, so Aldi rows have inStock, rating and ean empty.

Why are Asda ingredients and nutrition empty? Asda serves ingredients and nutrition only on its product pages, and those pages refuse requests from Apify's servers. Asda prices, offers, stock, ratings and categories come from Asda's product search and work normally. Asda rows without details are not charged the Product details event.

What is the difference between price, wasPrice and loyaltyPrice? price is what you pay without a loyalty card. wasPrice is the earlier price the shop shows next to an offer, such as an Asda Rollback or a Morrisons "Was £3.90". loyaltyPrice is the Clubcard, Nectar or More Card price. Morrisons gives the regular price and the offer as text ("Now £3, Was £3.90", "Half price"), and the Actor works out the price you pay from that text.

How does Basket mode pick a product for each item? A product counts as a match only if its name contains every word of the item (plural forms count, and "6" matches "6 pack" or "x6"). With Cheapest by unit price, the Actor stays on the shelf of the shop's own best match and takes the lowest unit price there, so "bananas" is not matched with banana yogurt. With Top search result, it takes the shop's first match. A shop missing any item is not counted as the cheapest complete basket.

How does price history work? With Keep weekly price history on, each product's price for the current ISO week is stored in a key-value store named uk-grocery-price-history in your Apify account. A product gets a priceHistory list once it has prices from two or more weeks, so the history starts filling up from your second weekly run. Up to 104 weeks are kept per product.

How many products can I get? Search and category results go as deep as each shop's own results. In our tests, Catalogue mode returned the whole Asda grocery range, 34,373 products, in about 25 minutes, and 3,000 Morrisons products in about 2 minutes. Asda's catalogue leaves out its Home & Entertainment (George) range. Asda's search returns at most 1,000 results per query, so large Asda categories are read through their sub-categories. Products Asda hides from its online shop are left out, as on asda.com.

Are prices the same in every store? The Actor returns the online grocery prices each shop's website shows. Asda prices come from its online price list for England. Prices in physical stores can differ.

Can I schedule the scraper and connect it to other tools? Yes. Use Apify schedules to run it daily or weekly, and connect the results to Google Sheets, Slack, Make, Zapier, n8n, or your own system through integrations, webhooks, or the API.

Something does not work or a field is missing. Open an issue on the Issues tab with your input and run ID, and we will look into it.

Is it legal to scrape UK supermarket prices?

The Actor collects only public product and price information that the supermarkets show to every visitor of their websites. It does not collect personal data. Check that your use of the data complies with each shop's terms and the laws that apply to you. For more background, read Apify's article Is web scraping legal? and consult a lawyer if you are unsure about your use case.
