Consultation No-Shows: Deposits, Fees and What Actually Reduces Them

A booked consultation is not an attended one

A clinic can get better at advertising and better at booking and still end the month with the same number of people in the chair. The diary fills, the week arrives, and some of it quietly empties again. Cost per lead is the wrong number makes the case for managing cost per booked consultation; this article is about the step after it, because a booking you paid to create and nobody attended cost exactly as much as one that worked.

That is the reason booking and attendance have to be counted separately. Treated as one number they hide each other: a clinic congratulating itself on a full diary cannot see that a fifth of it will not arrive, and a clinic blaming its advertising for a quiet month may have a booking process that works and an attendance problem it has never measured.

It is also why the common explanation is usually wrong. A missed appointment gets blamed on the lead, as though the person was never serious. Some were not. But the research on missed appointments points mostly at things the clinic controls or can see coming, and the strongest of them is simply how long the patient was asked to wait.

What the evidence actually says

Why appointments are missed

The largest review of the question, published in Health Policy in 2018, went through 105 studies of missed medical appointments. Across them the average no-show rate was around 23 per cent, though the spread by region was enormous, from roughly 13 per cent in Oceania to 43 per cent in Africa, which tells you how little an average across settings means for any one clinic.

More useful than the average is what the review found predicted a miss. The determinants reported most often were a long lead time between booking and appointment, and a history of having missed before. Alongside those it listed younger adults, lower socioeconomic status, living further from the clinic, and not having private insurance.

Only one of those is fully in a clinic’s hands, and happily it is the one that came up most: the wait. An appointment eleven days out is a different proposition from one this Thursday, not because the patient is less sincere but because more life happens in between. That is why the first intervention is not a policy at all. It is booking sooner.

What reminders do

Reminders are the one intervention with properly randomised evidence behind them. A Cochrane review that included eight trials and 6,615 participants found, across the seven trials that compared a text message reminder with no reminder (5,841 participants), that text message reminders increased attendance, with a risk ratio of 1.14 and a confidence interval running from 1.03 to 1.26. The reviewers graded that moderate quality. Across those trials, attendance was 67.8 per cent where no reminder was sent and 78.6 per cent where a text was.

Two further findings are worth having. Text reminders performed similarly to telephone call reminders while costing substantially less per attendance, which matters for a small team. And the reviewers were careful about their own result: they wrote that the evidence remains insufficient to conclusively inform policy decisions, because the studies varied and reported little about outcomes beyond attendance. A reminder helps. It is not a solution, and anybody selling you one as a solution is going beyond the research.

What the evidence does not cover

Three gaps matter here, and they are the reason so much of what clinics are told about no-shows is assertion. There is no randomised evidence from private aesthetic clinics that we could find. There is no published UK no-show rate for aesthetic consultations that states its sample and method. And the effect of a deposit on attendance in this setting has not, as far as we can establish, been measured at all.

Deposits, booking fees and cancellation charges

These three are usually discussed as one thing and they are not. Separating them is most of the work, because they carry different intentions, different risks and different effects on who books in the first place.

What the evidence says about the money

The closest thing to a direct test is a randomised trial in Danish public hospital outpatient clinics, published in BMJ Open in 2018, where non-attendance was already around 5 per cent. Fining non-attendance did not further reduce it, and the authors suggested future work look at other approaches instead.

Be careful with that finding in both directions. It does not show that deposits never work: a public hospital fine issued after the fact is not the same instrument as a private clinic asking for a payment up front, the baseline was already low, and the setting is not ours. What it does show is that the assumption is not safe. Charging money for a missed appointment is widely believed to fix attendance, and the one randomised test of that belief did not find the effect.

The trade-off nobody mentions

A deposit changes two numbers, not one. It may improve the share of bookings that are attended, and it will reduce the number of bookings made. For a clinic with a full diary and a no-show problem that is a good trade. For a clinic with a thin diary it can be an expensive way to look more efficient, because a consultation that never gets booked cannot be attended either, and the advertising that produced the enquiry has already been paid for.

Which is why this is a decision to make with your own numbers rather than from a rule. If you introduce one, change nothing else at the same time, and compare bookings and attendance for the months either side. That is a small experiment your clinic can actually run, and it answers the question for your treatment, your prices and your patients, which no general study can.

The consumer-law frame

Terms of this kind are not simply a matter of preference. The Consumer Rights Act 2015 sets out, in Part 1 of Schedule 2, a list of contract terms that may be regarded as unfair. Three are directly relevant: a term letting the trader keep sums paid when the consumer decides not to proceed, without the consumer receiving equivalent compensation when the trader is the one cancelling; a term requiring the consumer to pay a disproportionately high sum where they decide not to proceed; and a term requiring a consumer who fails to fulfil their obligations to pay a disproportionately high sum in compensation.

The CMA’s guidance on those provisions, updated in July 2026, is more specific than the Act alone. It says a genuine deposit may legitimately be kept in full where it operates as a binding reservation, where the trader makes clear at the earliest opportunity that a deposit is required and the precise circumstances in which it would not be refunded, and where those circumstances are clear and narrow rather than leaving wide discretion. It adds that such a deposit will not normally be more than a small percentage of the price, and that a larger prepayment is more likely to be unfair because it may amount to a disguised penalty.

Size is therefore one consideration among several rather than the test. The same guidance treats a charge for cancelling as more likely to be fair where it is a genuine pre-estimate of the loss the business is likely to suffer rather than a punishment, and where it reflects the costs actually incurred, any saving to the business, and its ability to reduce the loss, for instance by filling the appointment with somebody else. A sliding scale can be acceptable if it is set out prominently enough to give the patient certainty, and never disproportionate. Keeping money for something the patient received no benefit from is treated as more likely to be unfair. Transparency runs through all of it: whether the patient was told in plain language, before committing, with a real opportunity to read the terms, and how the term sits alongside the rest of the contract.

Which is why the name matters less than the mechanics. Deposit, booking fee or holding payment, what is assessed is how the payment actually operates: what it is for, when it was disclosed, what happens to it when either side cancels, and whether what you keep bears a sensible relationship to what you lost.

One separate point concerns how the price is advertised rather than how the term is written. Under the current price transparency rules a charge the patient must pay in order to book is a mandatory charge, and the CMA names booking fees among administration fees, however they are described. So where a consultation price is advertised, the total the patient has to pay needs to include that fee rather than appearing later in the process.

The attendance system

Put the evidence together and it is a sequence rather than a policy, and the cheapest parts of it come first.

The fourth step is the one clinics most often get backwards. A patient who cannot easily change an appointment does not become a patient who attends the original one; they become a patient who does not turn up and does not get in touch. Making it simple to move a booking converts a silent loss into a later attendance, and it costs nothing but a reply. A rescheduled appointment is a legitimate outcome and should never be counted as a no-show.

None of this works if the first conversation was slow. An enquiry answered in minutes can be booked into this week while the person is still deciding; an enquiry answered tomorrow is booked further out, if at all, which puts lead time back where the research says the risk is. How quickly to contact a new enquiry covers that stage.

Measure your own attendance

You cannot manage this from a national average, and no aesthetics figure exists worth borrowing. You can manage it from your own numbers within a month of starting to keep them, and the counting is simple provided the definitions are fixed in advance.

Two counting rules keep the result honest. Count by the date of the appointment, not the date of the booking, because an appointment booked in March for April belongs to April. And decide before you start how a rescheduled appointment is treated: the cleanest approach is to count it once, at the date it was eventually attended or missed, so moving a booking neither creates nor destroys one.

1. 01

   Fix the period.

   A month of appointment dates, not booking dates.

2. 02

   Count the appointments due in it.

   Excluding any the clinic itself cancelled or moved.

3. 03

   Mark each one attended, cancelled or missed.

   On the day, by whoever was there.

4. 04

   Divide.

   Attended divided by appointments due gives your attendance rate. Missed divided by appointments due gives your no-show rate. Cancellations are reported alongside, not folded in.

5. 05

   Repeat, and compare only with yourself.

   Your own previous months are the only comparison available that describes your clinic.

Segment it as soon as you have enough to segment: by treatment, by how far ahead the appointment was booked, and by whether a deposit applied. The lead-time split is usually the most revealing, because it is the one the research predicts and the one you can act on next week. How to know whether your ads produce booked consultations sets out the record these marks belong on, so attendance can be read back to the campaign that produced the enquiry.

When enough installations have been counted this way, Outcome Reach will publish attendance figures, segmented and with the sample stated, at UK Aesthetic Patient Acquisition Benchmarks. Nothing is published today, which is exactly why this article teaches you to measure your own rather than hand you somebody else’s.

What the front desk can actually influence

Most of the attendance problem is decided by a handful of small behaviours at the point of booking, none of which require a policy or a system.

How Outcome Reach handles this

As a statement of our method rather than evidence: because the patient is answered within seconds and a person is in the conversation within minutes, the consultation is usually booked close to the enquiry, which is where the research says the risk sits. Attendance is then confirmed by the clinic and written back against the enquiry, so a campaign is judged on consultations attended rather than consultations booked. That is the whole reason our reporting separates the two. The system describes the components.
