No-Show Rates by Industry: What the Research Actually Says

The headline number

Across 105 published studies spanning appointment-based service industries, the average baseline no-show rate — often called "Did Not Attend" (DNA) or "Failed to Attend" (FTA) in the academic literature — is 23% (Etisia, 2026 benchmark review). Roughly one in four booked appointments goes unfilled.

That average hides enormous variation. A veterinary clinic and a free trial swim class have almost nothing in common when it comes to whether the customer turns up. Understanding your sector's baseline is the first step toward knowing how much improvement is realistic.

The sector baselines

Healthcare (outpatient and primary care): 7.6% to 42%. The NHS national average sits at 7.6% (NHS England). Specialised outpatient clinics run between 8.2% and 11.1% (NHS clinical studies). The evidence report's broader outpatient baseline range is 12% to 42% (Weave, 2026 review). Forgetting, logistical friction, and scheduling delays are the main drivers.

Fitness, sports, and personal training: 20% to 28%. Low perceived necessity and lack of financial penalties drive absenteeism. Youth swim schools and recreational sports share the same scheduling constraints and seasonal attendance patterns (Etisia, 2026).

Therapy, psychiatry, and counselling: 20% to 22%. Emotional avoidance and session anxieties contribute alongside logistical issues. The pattern partially transfers to educational tutoring, where students may avoid sessions they find academically difficult.

Beauty, salons, and wellness spas: 15% to 25%. Appointments seen as easily rescheduled, combined with the absence of card-on-file policies, push rates higher.

Professional services (legal, financial, veterinary): 10% to 15%. High perceived necessity and explicit billing expectations keep rates lower. These are essential services with formal commitments — the opposite of a discretionary children's activity.

Language and tuition centres (trial classes): 25% to 40%. This sits at the high end of the class-business benchmarks because free trials combine zero financial commitment with low salience. The booking costs the customer nothing to miss.

Why free trials run high

The evidence is clear on the mechanism. Free trial classes — common in youth sports, swim schools, tuition centres, and dance studios — suffer from what the literature calls a salience problem. Because there is no immediate cost to missing the slot, the appointment is easily forgotten. The customer has no skin in the game.

Requiring even a modest upfront deposit (25% to 50% of the service value) reduces no-show rates by 70% to 80%, a finding rooted in loss aversion: people are strongly motivated to avoid losing money they have already committed (ClassManager, 2026 review; SICUS Media, 2026 deposit-policy review).

That said, many class-based businesses offer free trials deliberately, as an acquisition strategy. If your model depends on free trials, a deposit changes the proposition; reminder flows are the report-backed way to address attendance while keeping the trial free. The next section of this pillar covers what the clinical evidence says about appointment reminders that work.

What a no-show costs

The direct cost is the empty slot that could have gone to someone else. For a class business, it is worse than that: a no-show trial means a lost enrolment opportunity, a wasted instructor slot, and a spot that was unavailable to a waitlisted family.

The evidence report focuses on preventing the no-show with reminders and on following up quickly after an attended trial. It does not quantify how many no-shows later convert, so treat recovery revenue as a separate question rather than an included benchmark.

Frequently Asked Questions

What is the average no-show rate for appointments?

Across 105 published studies, the average baseline no-show rate is 23%. Healthcare runs from 7.6% (NHS national average) to the report's broader outpatient range of 12% to 42%. Fitness and sports sit between 20% and 28%. Free trial classes at tuition centres and activity providers run 25% to 40%.

Can you charge a no-show fee in the UK?

The evidence report does not establish a general legal answer. If you use a fee or deposit, communicate it before the booking is confirmed, make sure the customer agrees to the terms, and check the applicable consumer-law requirements. Many salons and clinics use card-on-file policies or modest deposits. For free trial classes, a deposit converts the booking from a zero-commitment slot into one with financial weight, which research shows reduces no-shows by 70% to 80%.

Why do free trials have higher no-show rates?

Free trials remove the financial anchor that makes a booking feel committal. With no money at risk, the appointment is easily deprioritised when something else comes up. The academic term is a lack of salience — the booking does not hold enough weight in the customer's mind to survive a scheduling conflict.
