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.
Cancellation terms are set by each individual salon, not by Treatwell centrally. Before you confirm a booking, the cancellation window and any applicable fees are shown clearly on the booking page.
Most salons allow free cancellation up to 24 or 48 hours before the appointment. Cancellations inside that window may result in a charge or forfeiture of a prepaid amount. Spa days and some specialist treatments typically cannot be cancelled once booked regardless of timing. If you need to cancel, log into your Treatwell account and do so directly through My Bookings.
If a venue cancels your appointment, Treatwell will issue a full refund to your original payment method. If you have a complaint about a treatment or experience, contact Treatwell's customer support with your booking reference, appointment date and a description of the issue. Treatwell aims to resolve complaints within 24 hours.
For problems with a venue after a treatment, contacting the salon directly in the first instance is often the fastest route. If that does not resolve the issue, Treatwell's support team can escalate on your behalf.
Ways to Save at Treatwell
Book midweek and off-peak to access Smart Price discounts
Smart Prices are automatic discounts set by salons to fill quieter slots, typically midweek mornings and early afternoons. These appear at the search results level as a reduced price on a specific time slot, without requiring any code.
A treatment listed at £55 on a Saturday may appear at £44 on a Tuesday morning through the same salon. Filtering by day and time when you have flexibility is one of the most reliable ways to pay less on Treatwell, since these are genuine reductions rather than inflated-then-discounted prices.
Always prepay online rather than paying in the salon
Prepaying earns three points per £1 spent through twrewards, compared to one point per £1 when paying on the day in the salon. The treatment cost is identical either way.
On a £80 massage, prepaying earns 240 points versus 80. Points can be redeemed for a £10 voucher at 1,500 points or a £25 voucher at 2,500 points. For regular Treatwell customers, the difference in points accumulation over a year of bookings is meaningful.
Check last-minute availability before booking in advance
Salons set last-minute discounts to fill slots that would otherwise go empty, often on the same day or within 24 to 48 hours of the appointment. These can be 10% to 20% off the standard price and appear automatically in search results.
For treatments where timing is flexible, checking availability on the morning of the day you want a treatment regularly surfaces discounted slots that are not there a week in advance.
Apply a first-booking code before your first appointment
New customer codes are the most consistently available Treatwell codes and typically give 15% off a first booking. They are worth checking for before confirming any first appointment on the platform. The saving on a £50 treatment is £7.50, and on a £80 treatment it is £12.
The code field appears during checkout after you have selected your payment method, under Add Gift Card or Promo Code.
What Treatwell Gets Right
Treatwell solves a real and longstanding problem. Booking a hair or beauty appointment used to mean calling a salon during working hours, hoping someone picked up, and negotiating availability over the phone. Treatwell replaced that with 24-hour search, instant booking and verified reviews across thousands of venues in a single interface.
The verified review system is meaningfully different from self-reported ratings. Reviews on Treatwell can only be left by customers who have completed a verified booking through the platform. Venues cannot remove or respond to reviews in a way that alters their content. For a category where the quality of an individual stylist or therapist matters far more than the venue brand, that kind of independently verified review record is genuinely useful before spending money.
Smart Prices create real discounts, not manufactured ones. The off-peak and last-minute pricing system is set by the salon to fill genuine gaps in their diary, which means the reduced price reflects real supply and demand rather than an artificial markdown from an inflated number. A salon offering 15% off a Tuesday 10am slot has a practical reason to do so, which gives the discount more credibility than a headline promotional percentage.
Treatwell’s breadth makes price comparison straightforward for consumers. Searching for a Brazilian blow-dry or a sports massage in any UK city returns multiple venues, prices, availability and reviews in one view. Without a platform like this, comparing prices across individual salon websites requires visiting each one separately, with no guarantee of accurate or up-to-date availability. The aggregation saves time in a way that is easy to undervalue until you try to do it manually.
The gift card offer is one of the more flexible in the wellness sector. A Treatwell gift card can be used against any treatment at any participating venue with no expiry. For gifting, that removes the usual risk of giving a voucher for a specific salon that the recipient may not like or find convenient. The flexibility shifts the choice to the recipient rather than the buyer, which in a category as personal as hair and beauty is a meaningful advantage.
