Treatwell FAQs
Treatwell's checkout flow is slightly different from a standard retail site, as the code field appears partway through the payment screen rather than at the basket stage.
- Search for your treatment and location on treatwell.co.uk or the app
- Select your venue, treatment and appointment time, then click Go to Checkout
- Sign in or continue as a guest and choose your payment method
- Look for the Add Gift Card or Promo Code dropdown and click it
- Enter your code in the field and click Add Code
- Confirm the discount is showing in your total, then click Pay Now
One code can be used per booking. Codes are typically restricted to new customers and full-price treatments, and most have a minimum spend threshold of £30 to £45.
This varies by salon, since each partner sets their own cancellation window, typically somewhere between 24 and 72 hours. It's worth checking this carefully when you book, rather than assuming every salon works the same way.
Gift cards work differently. These can be cancelled within 14 days of purchase, as long as they haven't already been used or redeemed.
Ways to Save at Treatwell
Join Treatwell Rewards
TW Rewards is Treatwell’s own loyalty scheme, and it’s worth joining before your next booking. You’ll earn 3 points for every £1 spent when you pay online, or 1 point per £1 if you pay in the salon instead, so paying online is clearly the better route if points matter to you.
Once you’ve built up a balance, 1,500 points gets you a £10 voucher, or 2,500 points gets you £25 off. Points land in your account within 24 to 48 hours of your appointment.
Book off-peak or last-minute
Treatwell uses dynamic pricing, which they call smart pricing, meaning prices shift depending on demand. If you’re flexible on timing, booking during off-peak periods or picking up a last-minute slot can bring the price down significantly.
Refer a friend
Log into your Treatwell account to generate a personal referral link to share with friends or family. Once they sign up with a new account and complete a prepaid booking of £30 or more within 60 days, you’ll both get a £5 voucher, them after their first booking, and you once their appointment has taken place.
Sign up to the newsletter
Newsletter subscribers get access to member-only discounts, special offers, and updates on the latest beauty trends. It’s a low effort way to keep saving without needing to actively hunt for deals yourself.
Why We Like Treatwell
All beauty services in one app
It feels like there’s an app for everything these days, and Treatwell is a genuinely useful one to have. It covers pretty much every beauty service under one roof, from nails and hairdressing to massages and waxing. Download the app to quickly search for your next appointment and sign up for TW Rewards while you’re at it.
Helpful information and inspiration
The Treatment Files is Treatwell’s blog, covering the latest beauty trends and practical tips. Whether you’ve never heard of a lymphatic drainage massage or you’re trying to get rid of a blemish overnight, there’s a good chance it’s covered here.
Alongside that, Treatment Guides are organised by category, body, face, hair, hair removal, massages and nails, each with expert information on specific treatments, how they work, what to expect, and anything worth knowing beforehand.
Treatwell gift cards
Gifting money can feel a bit impersonal, and a standard gift card can feel limiting if you don’t know what the person actually wants. Treatwell solves both problems, thanks to its huge range of beauty services. Choose anything from £10 to £250, and have the digital gift card sent straight to whichever email address you choose
