The NHS may be free at the point of use, but private and mixed practices across the UK face the same challenge as their American counterparts: too many calls, not enough staff to answer them.
Walk into any GP surgery or dental practice during morning hours and you’ll see it. Reception staff juggling check-ins, prescription queries, and a phone that won’t stop ringing. Something has to give, and usually it’s the phone.
The result? Patients hear engaged tones or get pushed to voicemail. Many don’t leave messages. They try another practice instead.
The Numbers Don’t Lie
Research suggests UK medical practices miss 20-30% of inbound calls during peak periods. For a private dental practice where a new patient represents £1,500-3,000 in lifetime value, those missed calls translate directly to lost revenue.
But it’s not just about money. Patient access matters. When someone needs an appointment and can’t get through, that’s a failure of care delivery – even if clinical outcomes are excellent once they’re seen.
After-Hours: The Forgotten Gap
Most practices close their phones between 6pm and 8am. That’s 14 hours daily when patients reach voicemail or an out-of-hours message.
Yet patients don’t stop needing appointments at 6pm. Working professionals finally have time to call after work. Parents sort their children’s appointments after bedtime. Elderly patients have family members calling on their behalf during evening hours.

These calls go unanswered until the next morning, when staff are already overwhelmed with the day’s queue. Many patients simply give up or book elsewhere.
AI Voice Agents: A New Approach
A new category of technology is changing the equation: AI voice agents that answer calls naturally, 24 hours a day.
Unlike the clunky automated systems patients have learned to hate, modern AI conducts genuine conversations. Patients speak naturally – “I need to see the dentist next week, preferably Tuesday afternoon” – and the AI understands, checks availability, and books the appointment.
The technology has matured significantly. Response times under 500 milliseconds mean conversations flow naturally without awkward pauses. Integration with practice management systems means appointments are booked in real-time, not transcribed from messages the next day. Agencies like Custom Solutions AI are helping practices implement these systems with full compliance and support.
Platforms like talk.med are built specifically for healthcare, handling the compliance requirements that general-purpose AI tools cannot address. The AI manages routine calls – appointment booking, surgery hours, prescription queries – while routing genuinely urgent matters to human staff.
How UK Practices Are Using It
Smart practices deploy AI as augmentation, not replacement. Common configurations include overflow handling when reception is busy, after-hours coverage from 6pm to 8am, weekend and bank holiday availability, and first-line response with warm transfer for complex queries.
Staff often welcome the technology. Answering the same questions fifty times daily is exhausting. AI handles the repetitive work so humans can focus on patients who need personal attention.
The Competitive Reality
Patient expectations are shaped by every other industry. People book restaurants, cinema tickets, and retail appointments online instantly. Then they call their GP surgery and hear an engaged tone for twenty minutes.
Practices that meet modern expectations will retain patients. Those that don’t will watch them walk to competitors who answer the phone at 7pm on a Tuesday.
The technology exists. The ROI is clear. The question is which practices will move first.
