Notes from the shoes desk
Where the offers stand today
Start by checking what codes Size has live on this page, since the retailer issues them regularly across product categories and collections. Size has 20 codes in rotation, with discounts reaching up to 22%. For a Shoes retailer in the United Kingdom market, that is a solid board, though the depth of sitewide codes versus category-specific ones will depend on the week.
The kind of offers this retailer issues
Size issues codes almost entirely as percentage discounts rather than flat pounds off. The sample titles show codes that work sitewide (everything, full price clothing, your shopping cart) alongside others locked to categories like coats or sale sections. Some codes also trigger specific perks like free delivery or Apple Pay bonuses. This mix means waiting for a sitewide code is sometimes worth it, but category-specific codes move frequently enough that a shopper hunting one product may find it discounted within days.
When it is worth waiting
The Shoes category sees deeper discounts in late summer and winter clearance windows. Between those peaks, retailers in this space typically hold steady with percentage-off codes in the 15 to 25 range, meaning now is a reasonable time to buy if you need a specific style rather than wait for a seasonal event. Size's code rhythm suggests checking back monthly rather than weekly, since sample titles indicate the retailer rotates offers on a broad schedule rather than daily.
What trips people up at checkout
- Regional site and shipping scope. Size operates size.co.uk for United Kingdom shoppers; codes issued on this storefront typically apply only to orders shipping within the UK market. Check the code terms at checkout to confirm your delivery location qualifies, since the tracker reflects the regional site feed and does not cross-verify international applicability.
- Free delivery codes require the app. The sample titles show at least one free delivery offer requires using the Size app to redeem it. If you shop on the website instead, that particular code may not work or may specify app-only terms at checkout.
- Category limits on some codes. Codes are scattered across full price, sale, and specific product types like coats. Before applying a code, scan its title for category language or check the fine print at checkout, since a percentage-off code for sale items will not work on full price Shoes even if the percentage is high.
Desk note
All 20 offers on this page come from merchant and affiliate network feeds, never from user submissions, and the whole page is matched against those feeds once a day. An offer that leaves the feed is retired the same day and stays listed as retired for 60 days, because a retired code often still works. Nobody here writes a code by hand and nobody places a test order, so we never tell you an offer worked for us. A code that fails for you goes to the desk queue through the report button the same day.

How to use a Size UK offer
-
Pick the offer that fits your cart
Offers on this page are ordered by how much they take off, not by how recent they are. Read the line under each one: it shows when the offer entered the tracker and, where the retailer states it, when it ends.
-
Reveal the code
Codes are not printed in the page. Selecting an offer reveals the code and opens the retailer in a new tab at the same time, so you can paste it straight into the cart.
-
Paste it at checkout before you pay
Enter the code in the promo or discount field and confirm the total changes before completing the order. A code that applies but takes off less than expected usually means part of the cart is excluded.
-
Report it if it fails
If the offer does not apply, use the report button on this page. It goes to the desk queue the same day, and an offer that fails twice is retired.
Size UK offers, questions we can answer from the data
How many Size UK offers are live right now?
20 offers are live on this page right now. All of them need a code at checkout. The page was last matched against the merchant feed on October 2, 2026.
What is the best Size UK discount available?
The deepest discount on this page takes 22% off. 7 of the current offers read as sitewide, so they are not tied to one product line.
Does Size UK give a first order discount?
Not in the current set. None of the offers on this page are marked for first orders only, so what you see applies whether or not you have ordered before.
What should I do if a Size UK code does not work?
Check the terms under the offer first: most rejections come from a spend threshold, an excluded product line, or a first order restriction. If the code still fails, use the report button on this page. It goes to the desk queue the same day, and a code that fails twice is retired.
