Appointment reminder texts UK (2026): cut no-shows without annoying clients
How UK clinics, salons and trades can set up automatic text reminders: what they cost per text, ICO guidance on service messages, no-show fees and what to automate.

An empty chair costs you twice: you lose the fee, and you can’t offer the slot to someone else because you didn’t know it was free. Clinics, salons, physios, dog groomers and trades all feel this, and you probably already have a phone number for every client. An automatic text the day before is the simplest fix, and it’s cheap. This guide covers what to send and when, what it costs, what the ICO says you can send without marketing consent, and how to handle the clients who still don’t turn up.
Prices and rules checked on Square Appointments' UK pricing page, Fresha's pricing page, Cliniko's pricing page, Cliniko's SMS credits help article, FireText's pricing page, The SMS Works' pricing page and Twilio's UK SMS pricing page, and guidance on the ICO's guide to identifying direct marketing, the ICO's marketing guidance for small organisations, guide to PECR on electronic mail marketing and the CMA's unfair contract terms guidance, and figures on NHS England Digital's Appointments in General Practice, August 2026, on 27 October 2026. Prices and offers change often, so check before you buy. We have no commercial deal with any of the tools in this guide.
The short answer
- You already use a booking system: look for its reminder settings first. Square Appointments, Fresha and Cliniko all list text reminders. It’s usually a switch, not a project.
- Keep reminders as service messages: the ICO says a reminder about an appointment isn’t direct marketing. Add an offer and it becomes marketing.
- Make it easy to cancel or rebook: a reminder that lets a client say “I can’t make it” gives you the slot back in time to fill it.
- Budget pennies, not pounds: the UK SMS providers we checked list standard rates of 4.4p to 5p a text, excluding VAT.
- If no-shows still hurt, add a clear cancellation policy, then a deposit or card on file. Make sure clients see the terms before they book.
How big is the problem?
It depends on your business, so measure your own before and after. For a sense of scale, NHS England Digital reports that 89.6% of GP appointments in England were attended in August 2026, out of 29.8 million recorded. Not every appointment outside that 89.6% was a no-show, so don’t read the rest as a no-show rate. Still, it shows that even essential appointments get missed.
To find yours, take the last three months from your diary and count:
- appointments booked;
- no-shows (didn’t turn up, didn’t tell you);
- late cancellations (told you too late to refill the slot);
- the average value of a missed appointment.
Multiply the missed appointments by the average value, then divide by three. That gives you a monthly cost to compare against the price of reminders.
What the ICO says you can send
You can send reminder texts without marketing consent, as long as you keep them clean. The ICO’s guidance says data protection law and PECR (the Privacy and Electronic Communications Regulations) “don’t stop you from telling your customers important information”. It calls these service messages and lists messages to “confirm or remind them about appointments” as an example.
Its small business guidance gives a clear example of the line. “Our engineer will be round to service your central heating system at 10am on Tuesday” is a service message. Add “You can save money on your service by signing up to our Home Care plan” and it counts as marketing.
In practice:
- Do include the date, time, place and how to cancel or rebook.
- Don’t add offers, new treatments, review requests with incentives or “book your next visit and save”.
- Keep it discreet. Texts show up on lock screens. “Your appointment at [business name] is at 10:30 on Thursday” is enough. Leave out what the treatment is for.
- Use the number for its purpose. Marketing texts follow stricter rules. The ICO’s guide to PECR on electronic mail marketing says you must not send marketing texts to individuals “without specific consent”, with a limited exception for your own previous customers, often called the “soft opt-in”. That exception needs a simple way to opt out when you collect the number and in every message. Keep reminder and marketing lists separate.
What to send, and when
A simple pattern, which many booking systems support:
- At booking: a confirmation with the date, time and address.
- A day or two before: a reminder with a way to confirm or cancel. Send it early enough that you could still fill the slot.
- On the day (optional): a short note for early morning appointments or home visits, such as “Our engineer is on the way”.
Some example wording you can adapt. Each stays under 160 characters, so it counts as one text:
- “Hi Sam, reminder: your appointment at [business name] is Wed 4 Nov at 10:30. Can’t make it? Reply C to cancel or call 01632 960123.”
- “Hi Priya, your cut and colour at [business name] is tomorrow at 2pm. To move it, use the link in your booking email.”
- “Hi Mr Jones, our engineer will arrive between 8am and 10am on Friday. Reply if no one will be home.”
Only offer “Reply C to cancel” if replies come back somewhere you or your system can see them. A reply number can cost extra: FireText, for example, lists a UK reply number at £9 a month excluding VAT.
What reminder texts cost
Prices from the providers’ own pages on 27 October 2026:
| Option | What you pay | Notes |
|---|---|---|
| Square Appointments Free | £0 for one location | Lists text and email reminders on every plan |
| Square Appointments Plus | £29 a month per location | Adds client confirmations, custom text notifications and cancellation fees |
| Fresha | Monthly allowance, then a charge per text | Lists 100 free messages a month on its Independent plan and 100 per team member on Team |
| Cliniko | SMS credits bought separately | Help article: 1 credit is 1 message up to 160 characters, bought in lots of 200 or more |
| FireText | £25 for 500 credits, 5p each, excluding VAT | 1 credit is 1 text fragment to 1 UK number |
| The SMS Works | 4.4p a text standard rate, excluding VAT | Showed an introductory rate from 3.1p when we checked |
| Twilio | US$0.056 per segment to UK numbers | Pay as you go, built for developers |
Notes on these figures:
- Currency. Fresha’s and Cliniko’s pricing pages showed US dollars when we checked from our network, so UK visitors may see different prices. We’ve left their amounts out. Check their pages from the UK.
- Length. A text over 160 characters is usually split and charged as two or more. Cliniko’s credits and FireText’s fragments both work this way, and Twilio charges per segment.
- VAT. FireText and The SMS Works show prices excluding VAT. Add 20% if you can’t reclaim it.
A worked example. A salon with 300 appointments a month sends one reminder for each. At FireText’s 5p a credit, that’s £15 a month excluding VAT. At The SMS Works’ 4.4p standard rate, it’s £13.20. If a single saved appointment is worth more than that, the reminders pay for themselves.
When reminders aren’t enough
Reminders help clients who forget. They don’t fix clients who don’t value the slot. Next steps, in order:
- A written cancellation policy. State how much notice you need and what happens if a client doesn’t give it. Show it when they book and in the confirmation.
- Card on file or a deposit. Square Appointments lists prepayments on every plan, and cancellation policies with fees on Plus and Premium. Fresha lists upfront payments and no-show and cancellation fees. Card payment fees apply, so check each provider’s rates.
- Keep it fair. The Consumer Rights Act 2015 sets out the law on unfair terms in consumer contracts, and the CMA’s guidance (updated 22 July 2026) explains how to make terms fair and transparent. A fee that’s clearly shown before booking and in proportion to your loss is much easier to defend than a surprise charge.
- A cancellation list. When someone cancels after a reminder, offer the slot to the next person. Check whether your booking system has a cancellation list feature before building one.
Trades and businesses without a booking system
If you take bookings by phone and keep them in a calendar, a spreadsheet or a job management app, you can still send reminders:
- Check your existing tools first. If you use a job management or booking app, look in its settings for reminders before you build anything.
- Connect your calendar to an SMS provider. With Zapier, Make or n8n, a new calendar event or job can trigger a reminder a day before through a provider such as Twilio or FireText. See our n8n vs Make vs Zapier guide to choose a platform.
- Clean up phone numbers first. Reminders only work if numbers are stored in one format, such as +44 7700 900123.
- Log every message, so you can see who was reminded when a client disputes a fee.
If your bookings come from your website or phone calls, our guides to automating website enquiries and how AI can help UK small businesses cover the step before the reminder.
When to get help
If you have a booking system, you can usually switch reminders on yourself. Help is worth paying for if your appointments live across several systems, you want a two-way flow where replies update your diary, or you want missed appointments to trigger rebooking and a cancellation list automatically. For what that kind of work costs, see our guide to AI automation costs in the UK.
In the UK, workflow automation is mentioned by 231 agencies, and AI chatbots by 97 agencies. Browse workflow automation agencies, or use Get matched and we’ll suggest suitable agencies at no cost.
