About Smile Aligners
Smile Aligners is a UK online shop selling at-home clear aligner plans. Customers start either by booking a 3D scan at one of the partner scan centres the site lists (London, Edinburgh, Birmingham, Crawley, Plymouth and Manchester) or by ordering an impression kit to use at home, and the rest of the process is handled remotely.
The range is short: two DayNight plans and two NightFit plans, each available for one arch or both arches, plus the impression kit, retainers and cleaning extras. Prices are shown in pounds, and the plans can be spread into monthly payments through Partial.ly. The site's FAQ says no in-person appointments are needed.
The trading company appears to be Smile Aligners Ltd, a private limited company incorporated in September 2025 with a registered office in Erith, south-east London, and registered under a general online retail business code. The site offers a suitability guarantee: if the case is judged unsuitable after the impressions are reviewed, the treatment fee is refunded. There are also flat discounts for students, Blue Light Card holders and military personnel, and a referral reward.

Can I use more than one Smile Aligners discount code?
Usually not: most stores, including Smile Aligners, accept one discount code per order. Automatic deals and sale prices can often be combined with a code, so check the terms on each offer.
Does Smile Aligners offer a first-order discount?
We don't have a first-order code for Smile Aligners right now. Sign up for alerts and we'll email you if one lands.
Can I use a Smile Aligners discount code on sale items?
It depends on the code. Many discount codes exclude items that are already reduced, so open Terms on the code before you use it.
Can I combine the Smile Aligners student discount with other offers?
Usually not with another discount code, as most stores take one code per order. Student discount often still applies to sale prices and alongside free-delivery deals, so check the terms of the student offer.

Are these Smile Aligners codes verified?
Codes marked Verified have passed our check, with the date and time shown on the code. We use AI to validate that codes actually work. Codes without the badge come from Smile Aligners itself or its affiliate programme but haven't been verified yet.
Does Voucher Magpie donate to charity?
Yes. When you buy from Smile Aligners through our links, Smile Aligners pays us a commission, and we give 50% of it to the charity you choose. We donate once Smile Aligners confirms the sale, usually 30 to 90 days later, and pay charities once a year.
Does using Voucher Magpie cost more?
No. You pay Smile Aligners's normal price, less any discount. Our commission is paid by Smile Aligners or its affiliate network, not by you.
