Valid Dulux discount codes for Mar 2026

You can often find Dulux discount codes in a few ways. New customers might get a discount, such as 10% off their first order, by signing up for the Dulux newsletter. It's also worth checking various voucher code websites, as these often list current Dulux offers and promotional codes. Dulux sometimes runs seasonal sales too, with newsletter subscribers potentially getting early access.

Applying a Dulux discount code is pretty straightforward. First, add the paint or other items you want to buy to your basket on dulux.co.uk. When you're ready to pay, head to the checkout page. You should see a designated box, often labelled \"promo code,\" \"discount code,\" or \"voucher code.\" Simply type or paste your code into this box and click \"apply\" or \"submit\" to see the discount reflected in your total.

If your Dulux discount code isn't applying, there are a few common things to check. Make sure you've entered the code exactly as it appears, as they can be case-sensitive. The code might also have an expiry date, so check if it's still valid. Sometimes, codes are only for specific products, categories, or require a minimum order amount, so ensure your basket meets any terms and conditions. It's also possible a code has reached its redemption limit or is for one-time use only.

Yes, you can often qualify for free delivery when ordering from dulux.co.uk. Standard delivery is free for orders over £100. If you're just ordering tester pots, such as Dulux Colour Testers or Peel & Stick Samples, these typically ship via Royal Mail with a reduced charge, and if you order three or more tester items, or a tester bundle, delivery is usually free.

Dulux generally offers a returns process if there's an issue with your order, such as receiving the wrong size. If you've ordered paint and simply changed your mind, Dulux does not typically offer returns for opened paint cans. However, if the product is unopened, unused, and still in its original, undamaged packaging, you may be able to return it within 30 days of purchase. For faulty or damaged products, Dulux will usually offer a replacement or refund in line with your consumer rights. To arrange a return, you'll need to contact Dulux Customer Care.
