Diesel Discount Codes

Diesel is running a 50% off sale on kids jeans, joggers and shorts, which is the headline offer here and best for anyone buying children's denim or active bottoms. The sale applies only to the listed kids items and cannot be combined with other promotions, so it suits you if those exact items are what you need. For other categories there are separate bundle and price from deals and a sitewide free delivery threshold to consider.

If you are buying kids jeans, joggers or shorts: take the 50% off kids sale. The half price reduction applies directly to the marked kids items and beats any of the other fixed price bundle deals when those are not on the same products, because the sale cannot be stacked with other promotions.

If you want single adult polo shirts: choose the polo shirts from €21.45 offer. When you pick a qualifying polo at €21.45 you pay that price rather than relying on a percentage code that may not apply to that style.

If you are buying two loungewear or underwear items: use the buy 2 loungewear and underwear for €35 deal. That fixed two for €35 price applies when you add two eligible items to your basket and cannot be used with other promotions.

If you plan to buy two T shirts: the buy 2 T shirts for €45 deal is the one to use, because the saving only applies when you take two qualifying T shirts and, again, it cannot be combined with other discounts on the same items.

If you are buying vests or bra tops: compare the two for €30 bundle against the from €4.99 single item prices. For two qualifying vests or bra tops the €30 two for deal will usually be cheaper than buying two at the lowest single price if those single items are above €15 each.

If your order is €40 or more: you will get free shipping on deliveries to addresses in Ireland, so factor that saving into any choice. For very small orders under €40 the free delivery does not apply.

If you are hunting sale bargains: the up to 70% off sale styles can give the biggest price cuts, but note sale items cannot be used with other promotions. If the items you want are in the sale and marked down up to 70%, that is likely the best saving compared with the fixed price bundles or the kids sale on other lines.

Our records show 13 offers listed for the brand in the 12 months to November 2026 (12 sales and deals, 1 code), the biggest percentage code in that period was 20% off, and the largest sale has been up to 70% off. Our team carried out one checkout test across one offer in the 12 months to November 2026 and kept a screenshot as proof.

When choosing, add the exact items you want to your basket and compare the totals. Pick the single deal that gives the lowest final price for those items; where an offer term says it cannot be combined, you must choose between those offers rather than stacking them.

Enter your discount code in the discount code or gift card field at checkout, then apply it before paying. Check that the order total changes and that the saving covers the items you intended to buy. If a code is rejected, compare your basket with its conditions, including eligible products and any spending requirement.

• Sale and outlet: Check both before paying full price, particularly if you can be flexible about colour or style. Compare the final price of the item you want, not just the advertised reduction.
• Multi-buy offers: Selected T-shirts and socks feature in bundle promotions. These make more sense when you need every item in the bundle.
• Student savings: Eligible students can access a discount after student email verification. Complete verification before checking out and read the offer conditions.
• Newsletter offers: Email sign-up offers include a first-order discount and updates about exclusive promotions. Check the welcome message for the conditions before placing your order.
• Delivery threshold: Free delivery is available above a minimum spend. Compare any shortfall with the delivery charge before adding something you do not need.

Irish online orders use tracked An Post delivery. Orders are generally dispatched within 24 hours on working days, with delivery usually the next working day after dispatch. Busy periods can cause delays, so allow extra time if you need something for a particular date.

Payment options include Visa, Mastercard, Maestro, PayPal, Apple Pay, Google Pay and Shop Pay.

Online purchases can be returned within 30 days of receipt, provided they are unworn and retain their original packaging and labels. You can use the free An Post drop-off return service or take an online order to a Diesel store with the order confirmation QR code. Gift cards and underwear cannot be returned. Purchases made in a store have a separate 14-day return period, so do not apply the online deadline to a shop purchase.

The Irish Members Club lets you collect points and redeem them for discounts. Registration earns points, and the scheme has Bronze, Silver and Gold tiers with different earning rates and benefits. Higher tiers include exclusive offers, while Gold includes early access to new items.

Birthday rewards and referrals provide other ways to collect points. If you expect to shop repeatedly, compare the points you can redeem with any separate discount available for your order. Treat points as a saving on purchases you already planned, rather than a reason to spend more to reach another tier.

If you are comparing prices for jeans, casual clothing or footwear, browse our fashion offers before deciding where to buy. Compare the full basket cost, including delivery, rather than the headline discount alone.
