How to reduce no shows clinic-wide: a practical guide for practice managers

It's 9.40 on a Tuesday. The 9.30 hasn't arrived, the clinician is checking the waiting room, and somewhere in the practice inbox is a patient who rang yesterday asking for anything sooner. By 9.45 the slot is gone. If you're working out how to reduce no shows clinic-wide, this is the cost you're trying to stop: not an abstract percentage but a clinician sitting idle while someone who wanted that appointment waits another week.

This guide sets out what the published evidence says about missed appointments, then works through the changes that make the biggest difference: reminders from the system you already book in, cancellation routes patients will actually use, shorter booking lead times, a working waitlist, fair policies, and how you talk to patients about all of it. It's written for private clinics, physiotherapy and therapy practices, dental and aesthetics clinics, and GP practice managers. Most of it costs little or nothing.

What the data says about missed clinic appointments

Before changing anything, it helps to know how big the problem is in your setting, and what kind of problem it is. The national figures are a useful benchmark.

NHS England's general practice figures

According to NHS England's March 2026 release on missed appointments, patients did not attend 16 million GP practice appointments in 2025, about 1 in 23 (4.3%) of the 376 million appointments booked. The same release reported a survey in which nearly one in four people said they had missed an NHS appointment because they forgot or arrived too late: 12% said they had forgotten an appointment and 11% that they had arrived late. The campaign that went with it asked patients to switch on NHS App notifications and to cancel or rearrange appointments they can't keep.

An earlier NHS England analysis from January 2019 put the share at about 5% of the roughly 307 million appointments scheduled each year in general practice, or more than 15 million slots, with around 7.2 million of them with GPs. At an average cost of £30 per appointment, NHS England estimated the waste at more than £216 million a year. Those cost figures are now seven years old, but the message from both releases is the same: a large share of missed appointments come from people who forgot or didn't cancel, not people who chose to stay away.

If you work in general practice, your own monthly data sits in the Appointments in General Practice statistics published by NHS England, where the "did not attend" status is broken down by practice and appointment type. Compare your rate with practices like yours before deciding whether you have a problem worth a project.

What the research says about why patients miss appointments

A 2018 systematic review by Dantas and colleagues in Health Policy, No-shows in appointment scheduling, looked at 105 studies from across healthcare and found an average no-show rate of around 23%, with very wide variation between settings and countries. Across the studies, two factors came up again and again as predictors: a long gap between booking and the appointment (lead time), and a history of previous no-shows.

Both of those are things a clinic can act on. You can shorten the gap between booking and appointment for the services where it matters, and you can treat repeat non-attenders as a group that needs a different approach rather than the same reminder everyone else gets.

Missed appointments can be a warning sign

There's a reason to be careful about how punitive your approach gets. A study of more than 800,000 patients in Scottish general practice, published by McQueenie and colleagues in BMC Medicine in 2019, found that patients with long-term health conditions who repeatedly missed appointments had a much higher risk of death than those who didn't, and the association was strongest among patients with mental health conditions. Some of the people who don't turn up are the people a practice most needs to reach.

That doesn't mean doing nothing about no-shows. It means separating the two groups: patients who forgot or couldn't get through to cancel, for whom convenience fixes work well, and patients who repeatedly miss, for whom a phone call from a person may matter more than a policy letter.

How to reduce no shows clinic-wide: the order to do things in

There's a temptation to start with the most visible measure, a strongly worded policy or a fee. The evidence points the other way. Start with the cheap, convenience fixes that help the forgetful majority, measure, and only then decide whether you need firmer measures for the minority.

The rest of this guide goes through each step.

Step 1: measure missed appointments properly

You can't tell whether a change worked if you don't know where you started. Most practice and booking systems record an appointment status: attended, did not attend, cancelled by patient, cancelled by practice. Pull three months of data and work out:

• Your DNA rate, as did-not-attend appointments divided by all booked appointments, overall and by clinician, appointment type and day of the week.
• Late cancellations, meaning cancellations inside the window where you can no longer refill the slot. For many clinics that's under 24 hours, for some it's under 48. A late cancellation is often as costly as a no-show.
• Lead time for the appointments that were missed versus those that were attended. If your missed appointments cluster at four weeks out and beyond, that's useful.
• Repeat non-attenders: how many patients account for a disproportionate share of DNAs.
• Refill rate: when someone cancels with notice, how often does the slot get used?

That last figure is the one most clinics never look at, and it changes what you should do next. If cancelled slots rarely get refilled, the problem isn't only that patients don't show up. It's that the system for passing slots on doesn't work, which is a waitlist and communication problem.

A worked example of what missed appointments cost

The assumptions here are invented for illustration. Swap in your own.

Say a private physiotherapy clinic runs three clinicians, each seeing 14 patients a day, five days a week. That's 210 appointments a week. Assume a 6% no-show rate and an average appointment fee of £55.

• 210 × 6% = about 12.6 missed appointments a week.
• 12.6 × £55 = about £693 a week in fees not collected.
• Over 46 working weeks, that's roughly £31,900 a year.

Now assume that better reminders and easier cancellation cut the no-show rate to 4%, and that half of the extra cancellations that come in with notice get refilled from a waitlist. The no-shows fall to about 8.4 a week. You won't recover the full difference in revenue, because some of those patients simply cancel instead and not every slot refills, but even recovering half of the gap is worth around £5,000 a year in this example. For an NHS practice the cost is measured in clinician time rather than fees, but the arithmetic is the same.

Step 2: reminders through your practice system

This is the most researched part of the subject, and the evidence is reasonably consistent: reminders help.

What the evidence on reminders shows

The Cochrane review Mobile phone messaging reminders for attendance at healthcare appointments by Gurol-Urganci and colleagues (updated 2013) pooled eight randomised trials with 6,615 participants. It found that text message reminders increased attendance compared with no reminder or a postal reminder, and worked about as well as a phone call reminder, at lower cost. The authors rated the evidence as low to moderate quality, so treat it as a strong steer rather than proof of a specific percentage.

The wording of the reminder matters too. In a pair of randomised trials at Barts Health NHS Trust, published by Hallsworth and colleagues in PLOS ONE in 2015, around 10,000 outpatients in each trial received a text reminder five days before their appointment. In the first trial, the trust's existing message had a did-not-attend rate of 11.1%. A version that told patients the specific cost of a missed appointment to the NHS (based on an average of £161) cut that to 8.4%. The second trial repeated the result, and found that vaguer messages about cost, or appeals to empathy, worked less well than the specific figure. A message that simply added the cancellation number to the text, on its own, did not make a significant difference.

That last finding is worth sitting with. Making it easier to cancel is good for refilling slots, but a phone number in a text doesn't by itself make people turn up. Reminders and easy cancellation do different jobs, and you want both.

Practical reminder settings

Most systems used in UK clinics can send reminders, whether that's the clinical system in a GP practice, practice management software in dental and physio clinics, or general booking tools used by therapists and aesthetics clinics. Check what yours can do before buying anything new. Things to set:

• Timing. A common pattern is one reminder a few days before (time to rearrange) and one the day before (the "don't forget" nudge). The Barts trial sent its reminder five days ahead. For appointments booked weeks in advance, add a reminder at the point of booking that confirms the date.
• Channel. Text messages remain the default because almost everyone reads them. Email works for some patient groups. In NHS general practice, the NHS App can carry appointment notifications, which is what the 2026 campaign was promoting.
• Content. Include the date, time, clinician or service, location, and exactly how to cancel or rearrange. Keep clinical details out of the message: "your appointment at Riverside Physio" is fine; the reason for the appointment is not.
• A specific cost line. Based on the Barts finding, consider a short, factual line about what a missed appointment costs. Keep it plain, not guilt-tripping.
• Reply handling. If patients can reply "cancel" to a text, make sure someone or something actually processes those replies the same day.

Reminders for patients who don't respond to them

Reminders don't reach everyone. Some patients have changed numbers, some don't read texts, some have chaotic circumstances. For patients flagged as repeat non-attenders, or for high-value appointments like a first consultation or a long procedure, a short phone call from reception the day before is often worth the time. The Cochrane review found phone call reminders worked about as well as texts; the difference is cost, so target them.

Step 3: make cancelling easy at any hour

A patient lying awake at 11pm remembers they can't make tomorrow's 9.30. If the only route to cancel is phoning reception between 8am and 6pm, there's a good chance they'll mean to call in the morning, get caught up in the school run and not bother. You get a no-show instead of a cancellation, and no chance to refill the slot.

Every route a patient might try

List the ways patients try to contact you and check whether each one actually lets them cancel:

• Phone. Is it answered during the morning rush? Is there an out-of-hours option, even a dedicated voicemail line that is checked first thing?
• Reminder replies. Can patients reply to the reminder text to cancel?
• Online portal or app. Many patient portals and booking tools allow self-service cancellation. Is the link in every reminder?
• Email. Fine for some patients, but it needs checking early enough to refill the slot.
• Website chat or messaging. If your website or WhatsApp is how patients contact you, can they cancel there?

The NHS England campaign makes the same point from the patient's side: it asks people to cancel or rearrange appointments they can't keep. That only works if cancelling is easy.

The morning phone queue problem

The worst time for patients to get through is often the time they most need to: first thing in the morning, when the phone lines open and everyone rings at once. A patient trying to cancel their 10am at 8.05 may wait behind people calling for same-day appointments. Some give up. That's a no-show your system created.

Give cancellations a route that doesn't compete with the morning rush: a "press 2 to cancel" option that goes to a voicemail checked by 8.30, a reply-to-cancel text, an online link, or an assistant that answers every call.

Where an AI receptionist helps, and where it doesn't

This is the one part of the no-show problem where an AI receptionist such as Klugon's AI receptionist has a genuine role, and it's worth being exact about it.

What Klugon does:

• Answers every call and message, at any hour, while a plan is live. A patient who rings at 11pm to cancel gets an answer rather than a voicemail. See after-hours answering for how that works.
• Cancels or rearranges bookings held in Klugon's own calendar. If your clinic books through Klugon's built-in calendar (it uses your opening hours, service lengths and staff), the AI can cancel a booking on a phone call and offer a fresh slot. In chat and messaging, on your website, WhatsApp, Instagram or Messenger, it can reschedule an existing booking directly. A cancelled booking frees its slot straight away. See AI appointment booking for the detail.
• Takes a message when your bookings live elsewhere. If appointments are held in your clinical or practice management system, Klugon can't reach into that system. It can save the patient's details and the request as a lead with a note, and the conversation appears in your Klugon inbox for staff to action in the morning. On voice or social Business plans and above, new leads can also be posted to Slack or Zapier.

What Klugon does not do:

• It sends no reminders, no confirmations and no SMS. It doesn't make outbound calls.
• It takes no deposits and charges no no-show fees.
• It does no clinical triage. Anything clinical should be handed to a person, and the assistant should be set up to say so.
• It can't transfer a call live to a member of staff. It flags the conversation and your team follows up.
• It is not certified under HIPAA, SOC 2, ISO 27001 or similar schemes. Check your own data protection obligations, particularly in NHS settings, before using any AI tool with patient calls. The AI receptionist for medical practice page covers what NHS surgeries need to check first.

So the honest summary is that an AI receptionist won't stop a patient forgetting. It removes one specific cause of no-shows: the patient who wanted to cancel but couldn't get through.

A sample call

A sample call. The clinic and patient are made up, and this clinic books through Klugon's calendar.

The 9am slot is back in the diary by 11pm the night before, which gives reception a chance to offer it from the waitlist first thing.

Note what isn't in that call. The assistant doesn't promise to send a text confirmation or a reminder, because it can't. If your patients expect a written confirmation, that has to come from your booking or practice system.

Step 4: shorten booking lead times where you can

The Dantas review found that the gap between booking and appointment is one of the strongest predictors of no-shows. That fits what most receptionists already know: the further ahead an appointment is, the more likely the patient's plans change, the problem resolves, they find help elsewhere or they simply forget.

Ways clinics shorten lead times:

• Hold back a share of slots for booking within a few days, rather than releasing the whole diary weeks ahead. Many GP practices already do this with on-the-day and within-a-week capacity.
• Book follow-ups closer to the time. Instead of booking a follow-up six weeks out at the end of a consultation, some clinics put the patient on a recall list and contact them a week or two before. This trades a little admin for fewer forgotten appointments.
• Limit how far ahead patients can self-book. Most booking tools let you set a maximum booking window. Klugon's calendar has a setting for how far ahead bookings are allowed, which defaults to 60 days.
• Treat long-lead appointments differently. If you must book far ahead, for example a specialist session or a long treatment, send an extra reminder and ask for an active confirmation a week before.

There's a balance. Patients value being able to book their next appointment before they leave. For regular treatment courses, booking a block of appointments can work well because the routine is the reminder. Look at your own data from Step 1: if your missed appointments cluster at the long end, that's where to act.

Step 5: run a waitlist that fills gaps

Every cancellation with notice is only worth something if the slot gets used. Most clinics have a waitlist of some kind; far fewer have one that reliably fills a slot within an hour of a cancellation.

What a working waitlist looks like

• One list, in one place. Not a notebook at reception plus emails in someone's inbox. Many practice systems have a waitlist feature; use it.
• Clear details for each entry: name, contact number, the clinician or service they need, the times they can do and how much notice they need. "Any morning, can come in within an hour" is far more useful than just a name.
• A routine. Someone checks the next day's gaps at a set time each afternoon and first thing each morning, and works down the list.
• Patient self-service. Some booking tools notify waitlisted patients automatically when a slot opens. If yours does, turn it on. If not, a quick call to two or three people on the list is usually enough.
• A record of whether it worked. Track how many cancelled slots were refilled. This is the refill rate from Step 1, and it's the number that tells you whether your effort on easy cancellation is paying off.

Capturing waitlist requests out of hours

Patients often ask "is there anything sooner?" at times when nobody's around to note it down. If a patient rings or messages at the weekend asking for an earlier appointment, that request needs to land somewhere your team will see on Monday. An AI receptionist can capture it as a lead with the patient's details and availability, so it's in the inbox rather than lost. It won't contact the patient later when a slot opens, because Klugon doesn't make outbound calls or send texts; your team does that from the list.

Step 6: agree a fair, written policy

Once the convenience fixes are in place, you'll still have a small group of patients who repeatedly don't attend. That's where a written policy helps, provided it's fair and applied consistently.

Private clinics

Private clinics have more room to set terms, and many use a combination of:

• A cancellation notice period, usually 24 or 48 hours, stated at booking and in reminders.
• A late cancellation or missed appointment fee, sometimes a percentage of the fee and sometimes the full fee.
• Deposits or card details at booking for long or high-value appointments, which some booking and payment tools support.
• Discretion for genuine emergencies, applied consistently.

If you charge fees, they need to be clear before the patient books and proportionate to your actual loss. UK consumer law limits what businesses can charge; the government's consumer guide to cancelling goods or services explains that a cancellation charge must be a genuine estimate of the business's loss. If in doubt, take advice.

Klugon doesn't take deposits or charge fees, so if your clinic uses them, they need to sit in your booking or payment system. The AI can explain your policy to patients if you add it to its knowledge, so a patient who asks "is there a charge if I cancel?" gets the same answer at midnight as at midday.

NHS general practice

NHS GP practices can't charge patients for missed appointments. Policies tend to focus on communication: a letter after a set number of missed appointments, a conversation with a clinician, and in persistent cases, a review under the practice's own procedures. Given the McQueenie findings, many practices now treat repeated non-attendance first as a prompt to check whether the patient needs support, particularly with mental health conditions or complex needs, before considering anything firmer.

Writing the policy

A good no-show policy is short. It says:

1. How much notice you need to cancel, and why (so the slot can go to someone else).
2. Every way the patient can cancel, including out of hours.
3. What happens after a missed appointment, and after repeated ones.
4. Exceptions: emergencies, illness, caring responsibilities.
5. Where to ask questions.

Put it on your website, in booking confirmations and in reminders. Train reception to explain it the same way each time.

Step 7: talk to patients about missed appointments

The way you communicate makes a measurable difference, as the Barts trial showed. A few principles:

• Be specific and factual. "A missed appointment costs us £60 and means another patient waits longer" works better than "please be considerate".
• Tell people how, not just what. "If you can't make it, reply CANCEL or call us any time on 01632 960000" is more useful than "please let us know".
• Make the default easy. If patients have to find a phone number on a website to cancel, fewer will.
• Say thank you. Thank patients who cancel with notice. It sounds trivial; it reinforces the behaviour you want.
• Keep the tone non-judgemental. Patients who miss appointments are often struggling. Shame doesn't help, and it can drive people away from care they need.

Measuring whether it's working

Pick a start date for each change and compare the following, month on month:

• DNA rate, overall and by clinician and appointment type.
• Late cancellation rate.
• Refill rate for cancelled slots.
• Share of cancellations made out of hours, if your system records when a cancellation was made. If this goes up after you add an out-of-hours route, that route is doing its job.
• Repeat non-attenders: whether the group is shrinking.

If you use Klugon, its analytics page shows calls, bookings and the busiest hours, and every call and message appears in the inbox, so you can see how many cancellation calls arrive outside opening hours. Cancellation requests for appointments held in other systems are saved as leads, and the insights page lists leads nobody has contacted after two days, so requests don't sit unnoticed.

Give each change at least two or three months before judging it. No-show rates move around with seasons, school holidays and illness outbreaks, and a single good month means little.

Choosing tools for missed appointments

Here's a summary of the tool types and what each does for no-shows.

If you're looking at Klugon, the pricing page has the plans. The voice plan starts at $99 a month and the website chat plan at $49 a month. The free trial lasts 7 days and needs a card; phone numbers can only be added after the trial, so during the trial you test the assistant in the browser. The clinics overview covers other types of clinic, including dental practices and therapists.

Frequently asked questions

What is a normal no-show rate for a clinic?

It varies widely. In NHS general practice, NHS England reported that 4.3% of appointments were not attended in 2025. Across healthcare more broadly, the Dantas 2018 review found an average of around 23%, with large differences between countries and specialties. Compare yourself with similar clinics rather than a single benchmark.

Do text reminders actually reduce no-shows?

The Cochrane review found that text reminders increased attendance compared with no reminder or a postal reminder, and worked about as well as phone reminders, though the evidence was rated low to moderate quality. The Barts trial showed that wording matters, with a specific cost line performing best.

How far ahead should a clinic send reminders?

Many clinics send one reminder a few days before and another the day before. The first gives patients time to rearrange; the second catches those who forgot. Your practice or booking software will have timing options.

Does Klugon send appointment reminders?

No. Klugon doesn't send reminders, confirmations or text messages, and it doesn't make outbound calls. Use your practice or booking software for reminders. Klugon's role is answering calls and messages so patients can cancel or rearrange at any hour.

Can Klugon cancel appointments in our practice system?

Only for bookings held in Klugon's own calendar. If your appointments live in a clinical or practice management system, Klugon takes the patient's request as a message for your team to action. It can't change bookings in other systems.

Can a clinic charge for missed appointments?

Private clinics often charge a late cancellation or missed appointment fee, which should be stated clearly before booking and be proportionate to the clinic's loss. NHS GP practices can't charge patients. Take advice if you're unsure.

Should we remove patients who keep missing appointments?

Be cautious. Research from Scottish general practice found that repeated missed appointments among patients with long-term conditions were linked to higher mortality. Many practices now contact repeat non-attenders to check they're getting the support they need before taking firmer action.

What's the cheapest way to reduce no-shows?

Use the reminder features your current system already has, make cancelling easy outside opening hours, and run a waitlist that refills cancelled slots. None of these needs new software.

Missed appointments rarely have one cause, so they rarely have one fix. Start with reminders from your own system and an easy way to cancel, measure for a couple of months, then decide what else you need. If out-of-hours cancellations are part of your problem, the guide on how to never miss a customer call covers the options, and salon owners will find the companion guide on reducing no-shows at a salon more relevant.
