You've filled your basket, you're at checkout, and there it is: a £4.99 delivery charge you didn't budget for. It's one of the most common reasons UK shoppers abandon a basket altogether — and one of the easiest costs to avoid if you know where to look and how codes actually work.
This guide covers where free delivery codes come from, how to apply them properly, why they sometimes refuse to work, and the other ways to get free shipping when a code isn't available.
What a free delivery code actually does
A free delivery code is a type of discount code that removes the shipping charge at checkout rather than reducing the price of the items themselves. Retailers issue them for a few reasons: to clear seasonal stock, to reward newsletter sign-ups, to hit a promotional target, or simply to compete with rivals who already offer free shipping as standard.
Some codes remove delivery costs entirely. Others only apply once you've spent a minimum amount, or only cover standard (not next-day) delivery. It's worth checking which type you've got before you rely on it to make a purchase worthwhile.
Where to actually find working free delivery codes
Expired or fake codes are the biggest complaint shoppers have with delivery discounts, so it's worth knowing the reliable sources:
- Verified voucher sites. Browse PrimeVoucher's full list of UK stores to see which retailers currently have active free delivery offers, rather than searching store by store.
- Retailer newsletters. Most UK retailers send a free delivery or welcome code to new email sign-ups within a day or two.
- Retailer apps. App-only free delivery offers are increasingly common, particularly around seasonal sales.
- Loyalty or membership schemes. Some retailers waive delivery permanently once you join a free loyalty programme, so it's worth checking before hunting for a one-off code.
- Student, teacher and NHS discount schemes. These sometimes bundle free delivery in with a percentage discount see PrimeVoucher's student and teacher discount codes and NHS discount codes guides for retailers that qualify.
Codes found through unofficial forums or random social posts are far more likely to be expired, region-locked, or one-time codes someone else has already used.
How to apply a free delivery code at checkout
The mechanics are the same as any discount code: add your items to the basket, look for a box labelled "promo code," "discount code" or "voucher code" at checkout, paste the code in, and apply it before entering payment details. If you need a full step-by-step walkthrough — including what to do when the box isn't showing — see PrimeVoucher's guide on how to apply a discount code.
A couple of free-delivery-specific points worth flagging:
- The delivery charge often only updates
- Some retailers require you to select "free delivery" as the shipping option manually — the code won't automatically swap you from an express option.
Why your free delivery code isn't working
This is the most common frustration, and it's almost always one of these:
You haven't hit the minimum spend. Many "free delivery" codes are really "free delivery over £X" — check the terms before assuming it's unconditional.
The code excludes certain items. Sale items, pre-orders, gift cards and heavy or bulky products (furniture, appliances) are commonly excluded from free delivery promotions.
It's a new-customer or first-order code. If you've ordered from that retailer before, a welcome code typically won't apply, even if it isn't explicitly account-locked.
It's region-restricted. Some free delivery offers apply to mainland UK only and exclude the Scottish Highlands, Northern Ireland, and offshore islands.
It's already expired or been withdrawn. Delivery promotions tend to be shorter-lived than percentage-off codes, so a code that worked last week may simply be gone. Check PrimeVoucher's store pages for the current, verified offer rather than reusing an old one.
It only works on standard delivery. If you've upgraded to next-day or a specific time slot, the free delivery code usually won't cover the difference.
Getting free delivery without a code
If there's no working code for the retailer you want, a few other routes are worth checking:
- Subscription delivery passes. Services like Amazon Prime or ASOS Premier charge an upfront annual fee but remove delivery charges on every order afterwards — worth it if you shop with that retailer regularly, not worth it for a single purchase.
- Click and collect. Many UK retailers offer free click and collect to a local store even when home delivery is chargeable.
- Spend thresholds without a code. Some retailers apply free delivery automatically above a set spend, with no code needed — it's worth checking the delivery information page before assuming you need one.
- Cashback stacking. Even where delivery isn't free, stacking a cashback offer on top of your order can offset the cost. PrimeVoucher's guide on how to stack discount codes and cashback explains the order to apply them in so tracking isn't broken.
- Loyalty scheme perks. Free loyalty programmes sometimes include a set number of free deliveries per year, or free delivery on your birthday.
Retailers where free delivery codes are worth checking regularly
Free delivery offers are especially common with fashion and homeware retailers, where delivery charges are a bigger factor in whether shoppers complete a purchase. Browse PrimeVoucher's fashion category for current offers, or check individual retailer pages such as John Lewis and Tesco, which regularly run delivery promotions alongside their standard codes.
If you're comparing promo codes more broadly rather than delivery specifically, PrimeVoucher's guide to finding verified promo codes in the UK covers the wider picture.
Free delivery code FAQs
Do free delivery codes work on sale items?
Not always. Many retailers exclude sale, clearance or outlet items from free delivery promotions — check the code's terms or the retailer's delivery page if you're not sure.
Can I use a free delivery code more than once?
It depends on the code. Welcome or new-customer codes are usually single-use per account. Recurring or seasonal codes can often be reused until they expire, unless the retailer states otherwise.
Why does my code say "invalid" even though it hasn't expired?
This usually means the code doesn't apply to your basket — most often because you're under the minimum spend, an item in your basket is excluded, or the code is restricted to app orders or a specific customer group.
Is free delivery ever automatically applied without a code?
Yes. Many retailers set a spend threshold — for example, free delivery on orders over £50 — that applies automatically at checkout with no code required. Always check the delivery information page before searching for a code you might not need.
Are free delivery codes better than percentage-off codes?
It depends on your basket size. On a small order, a fixed delivery charge can be a bigger percentage of your total spend than a 10–15% discount code would save — so for low-value orders, free delivery is often the better deal.
