Smile Aligners: £30 off clear aligner plans with code HALLOWEEN30

Shopping at Smile Aligners? See all current Smile Aligners discount codes and deals, checked regularly.

Smile Aligners is a UK online shop selling at-home clear aligner plans. It suits adults who'd rather handle the process remotely: you 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 is done by post, video call and email. The range is short and clearly priced in pounds, which makes it easy to compare, and this Halloween there's a £30 code on top of the current sale prices.

What's worth a look

There are two styles of plan, DayNight (worn through the day) and NightFit (worn overnight), each for one arch or both, plus the kit you start with and retainers you can buy separately.

The plan pages list what's included: all the aligner stages, a set of retainers, a teeth whitening kit, an impression kit and free UK shipping. The homepage gives a wear time of 22 hours a day for DayNight and 10 hours a night for NightFit, so the choice mostly comes down to how the routine fits your day. If you'd rather not travel to a scan centre, the Smile Kit (£39.95) comes with impression trays, putty, gloves and instructions, plus a free video call with one of the team while you take your impressions. They then arrange collection, and you're sent a 3D treatment plan to look over.

Every plan can be split into monthly payments through Partial.ly, and the homepage shows the monthly figure next to each price. The Smile Aligners Guarantee says that if your case is judged unsuitable once your impressions or scans have been reviewed, the treatment fee you paid is refunded, with refunds processed within 7 working days of approval.

Current offers

• £30 off with code HALLOWEEN30: Smile Aligners told us about this Halloween offer, £30 off its clear aligner products, and the site banner shows it too. No end date is given, so use it sooner rather than later.
• Sale prices: all four plans are currently £400 below their crossed-out prices, for example DayNight Dual Arch at £625 (was £1,025).
• £25 off for students through the student discount page, with proof of student ID.
• £25 off for Blue Light Card holders through the Blue Card page, and £25 off for active and retired military personnel through the military discount page.
• 10% off your first order when you sign up to the newsletter in the site footer.
• £50 per referral through Refer and Earn when a friend you refer completes an order.

How to save more

• The single-arch plans cost £100 less than the dual-arch versions (£525 against £625 for DayNight), so check which one your treatment plan actually calls for before you pay.
• Every plan already includes an impression kit and a set of retainers, so you don't need to buy those separately at the start. Extra Smile Retainers (£104) are there if you want spares later.
• The site doesn't say whether HALLOWEEN30 can be combined with the £25 student, Blue Light or military discounts, so ask the team before you order. If only one applies, the £30 code is the bigger saving.
