The 20% off voucher at the top of this page is the lead Earth Breeze offer and is best for most orders where you can apply a discount code at checkout. It takes 20% off sitewide on web orders, so use that code if you want a straight percentage off a mixed basket. The other codes are lower percentage sitewide codes and several product bundles and sales give bigger savings on specific items.
Small baskets under £20, If you are buying a single pack or a small refill, use the 20% off voucher at the top of this page. For example, on a £15 order the 20% off voucher reduces the basket to £12 (20% percent off), saving £3. Very small purchases may also see the 15% or 10% codes work, but they save less than the 20% code.
Single product bundles and multi pack buys, If you are buying a 6 pack laundry sheet bundle, the six pack offer that gives 30% off the six pack may save more than a sitewide code because that 30% is applied to the bundle price as marked. For a 12 pack laundry sheet bundle the advertised 40% off bundle is likely the best choice for that product, because it is a targeted 40% reduction rather than the sitewide 20%.
Buying multiple packs (3, 6 or 12 pack thresholds), Several sale lines require you to add multiple packs to the cart. Use the 10% off when you buy 3 packs only if you cannot access a bundle that already has a larger percentage off. For six pack buys compare the 18% off when you buy 6 packs with the marked 30% off six pack bundle; the 30% bundle is better for those items. For 12 pack orders compare the 20% off when you buy 12 packs with the 40% 12 pack bundle, the 40% bundle wins for that product.
Buying selected sale items, When you buy marked sale products list prices may already be reduced up to 64% off or 30% off for specific items such as the dishwasher cleaner 4 pack. These sale prices are applied to selected products only; compare the final marked price with what you would pay after using the 20% sitewide voucher. Often a marked 40% or 64% price will be lower than a 20% off basket even before any code.
Our records show the biggest percentage code in the 12 months to October 2026 was 20% off and the typical code has been 10% off. Our team performed 9 checkout tests across 9 offers in the 12 months to October 2026 and kept screenshots as proof.
When choosing, take whichever option leaves the lowest total. Use the 20% off voucher at the top of this page for mixed baskets where no larger product specific sale applies. For specific bundles and multi pack buys use the bundle or marked sale price when it gives the bigger percentage. Note the 10% code that states it cannot be used with any other offers; otherwise the terms do not promise combining, so compare final totals rather than assuming codes stack.
