Extra Information

How To Get The Best Deals at HiSmile

This page contains affiliate links. If you use a code here, we may earn a small commission at no extra cost to you. Read our full affiliate disclosure.

Our team has tested the latest HiSmile discount codes this month and there's up to 40% off sitewide, up to 65% off sale items, and a free gift on selected orders right now, plus 10% off your first order when you sign up.

How To Use a HiSmile Discount Code at Checkout

I've ordered whitening kits and toothpaste from HiSmile a few times now, and the checkout is quick once you know where the code box sits. Add your items to the basket and head through to checkout.

There's a promo code field just above your order total. Paste your code in there and click apply before entering your payment details.

The discount comes off straight away, so check the updated total before confirming. If your code isn't applying, try a lower percentage code instead, since HiSmile often runs several tiers at once, from 10% up to 40%, and only one usually works per order.

What Kind Of Offers HiSmile Typically Runs

HiSmile is generous with sitewide percentage codes, and we regularly see a whole range running at the same time, anywhere from 10% off up to 40% off depending on the promotion. It's worth trying the highest one first, since lower tiers tend to still work if a bigger code has expired or excludes certain products.

Sale sections are worth checking too, with up to 65% off selected items when HiSmile clear older kits or limited edition ranges. Free gifts pop up regularly on qualifying orders, usually a smaller product like a toothbrush or travel size item bundled in automatically at checkout.

Delivery starts from £7.99, so it's worth comparing that against your total discount to make sure the order still works out cheaper overall. Sale periods tend to ramp up around New Year, when whitening kits are in high demand, and again around Black Friday.

Tips From Using HiSmile Ourselves

Follow the usage instructions on their whitening kits closely, since overusing them or leaving the gel on longer than recommended can cause sensitivity. We learned to stick to the suggested time exactly after trying to rush results once.

Check which sitewide code gives the biggest saving before applying, since HiSmile often has several live at once and it's easy to accidentally use a smaller discount than necessary.

Returns have been fine in our experience for unopened products, though used whitening kits typically can't be sent back for hygiene reasons, so it's worth reading the product page carefully before ordering.

Frequently Asked Questions

What is VoucherMe?

VoucherMe is a UK voucher and discount code platform. We track verified promo codes, exclusive discount deals, and brand offers across every major shopping category — so you spend less on the things you were buying anyway.

Are the coupons and promo codes free to use?

Yes, completely free. No sign-up, no subscription, no small print. Browse the deals, grab the code, use it at checkout. We earn a small affiliate commission from brands when you shop — but that never affects the price you pay.

How often are deals updated?

Every day. Expired codes get pulled, new ones go live, and anything time-sensitive gets clearly flagged so you know when to move fast. Worth bookmarking and checking before any online purchase.

Why is my coupon code not working?

A few common reasons — the code may have just expired, there's a minimum spend attached, or it's restricted to new customers only. Always check the deal terms listed next to the code before checkout. If something's consistently not working, let us know through our contact page and we'll look into it.

Do I need an account to use coupons?

No account needed on our end — just find your code and go. Some retailers may ask you to log in on their own site to apply a promo, but that's between you and them.

How does VoucherMe earn money?

We earn a small affiliate commission when you click through to a brand and make a purchase. You pay exactly the same price you would anyway — sometimes less, with the discount applied. It keeps VoucherMe free and the deals coming.
