Koh discount codes and coupon codes in November 2026
Get verified Koh promo codes and the latest vouchers to help you save
I’ve been a Senior Editor with CupoNation Australia since 2022, where I look after Koh deals and test discount codes a few times each week. My role is about making savings practical and dependable for everyday use.
I recommend sticking to the refill sizes once you own Koh’s reusable bottles. You’re paying for the cleaner rather than another bottle, and that adds up quickly if you clean a lot.
Koh makes cleaning products for people who want to avoid harsh chemicals around children, pets and the environment, while still getting a cleaner that works and doesn’t cost the earth.
The range is built around refillable, reusable and recyclable products, and its multipurpose formulas handle lots of jobs around the home, so you need fewer separate cleaners. Refill sizes let you top up the bottles you already own instead of buying new ones.
Subscribe & Save takes 15% off eligible refills every time they ship, from laundry liquid to dishwashing tabs. The 2L Universal Cleaner gets 10% instead.
Recurring orders ship for a flat $5, while the first order pays standard shipping or ships free over $119.
There's no lock-in, and you can pause, skip or cancel from your online account.
You get an email before each order is sent, and subscriptions earn bonus Koh Perks points.
Afterpay isn't available on subscriptions, so you'll pay by card or PayPal.
The $5 shipping is what makes this worth it for small top-ups. A single refill bought one-off under $119 costs $9.95 to ship to a metro address, so subscribing cuts both the price and the freight. Set the frequency a little longer than you need, as spare refills in the cupboard are money spent early.
Koh Perks is free to join with an account, and you earn points every time you shop. Points redeem for discounts on later orders, and members also get member-only gifts and discounts, early access to sales and VIP tiers that reward regular shoppers.
Redeemed points come off your order much like a Koh discount code, and subscriptions earn bonus points, so a regular refill order quietly builds your balance between bigger purchases. Early sale access is the perk worth joining for before a big restock, as you get first pick of reduced stock and still earn points on the order.
Share your referral link and your friend gets $20 off their first order as a Koh coupon code, while you collect 200 Perks points when they order. It suits anyone who's already won over a housemate or family member, since a first order usually means buying the reusable bottles and $20 takes a real chunk off that.
You need an account to get your link, and creating one signs you up for the points program too.
Standard delivery is free on orders over $119. Below that, Australia Post eParcel costs $9.95 to metro addresses and $11.95 to regional ones.
Express Post costs $14.95 metro and $16.95 regional, and there's no free express option.
Standard delivery takes 2 to 5 business days in capital cities and up to 16 business days to remote areas.
Orders ship from the closest of four distribution centres, so in a capital city express usually saves only a day or three. If you're within about $10 of the threshold, adding a refill you'd buy anyway costs roughly the same as the shipping fee and leaves you stocked up.
Starter kits bundle reusable bottles or tools with matching refills at a reduced kit price, with the saving shown against the regular price on each kit. They're the cheapest way in if you're new to the brand, because you'd need the bottles anyway. Choose a kit with refills you'll actually use, since a bigger discount on products that sit unopened isn't a saving.
If you're not happy within 30 days of receiving your order, you can request a refund through the Returns Portal, and opened or used products don't need to be sent back. Refunds are processed within 5 business days of the request being validated.
Change of mind returns are different, as you pay the return postage and the original shipping isn't refunded.
Loo Blades and Loo Rim Cleaner Blades are excluded for hygiene reasons.
That makes trying a new cleaner low risk, since you can still get your money back after testing it.
Select products carry a 12-month guarantee against faulty materials, workmanship or performance for home use. Refills, sponges, dishcloths, scrubby pads and the dish and grout brushes aren't covered, and neither is accidental damage. Valid claims go through the Returns Portal with proof of purchase, and you get a free prepaid return label if the item needs to come back. Keep your order email, because without proof of purchase a faulty tool turns into a full price replacement.
