Koh promo code - October 2026

New customers who register an account on the Koh website receive a welcome offer on their initial purchase. Set up your profile before checkout to make sure the discount applies to your first lot of cleaning supplies

Grab a larger pack of refill capsules and the price per clean drops compared to buying singles. Ideal if you already use Koh regularly and want to lock in a lower cost over several months of cleaning

Share your personal referral link from your account page. When your friend completes their first purchase, both of you receive a credit to put towards a future order - a solid way to save if you know someone keen to switch to eco-friendly cleaning

The dedicated sale section features discounted items including bundle packs and individual products at reduced prices. Worth checking before placing a full-price order since the deals rotate regularly

Pop your email in the signup form on the homepage to get notified about flash sales, new product drops and exclusive subscriber discounts. Handy if you want to catch refills when they go on special before they sell out

Drop a refill capsule into your existing Koh spray bottle instead of buying a whole new one. The capsules are priced well below the full bottle cost, meaning each top-up saves you money while cutting plastic waste

Buying a kit works out cheaper than grabbing the bottle and capsules individually. Each kit includes the Universal Cleaner spray bottle plus a set of refill capsules, so you've got everything ready to go without paying full price for each component
