The UK private health market has grown faster than its technology. That bill is now due.

The UK private healthcare market has had a remarkable five years. According to the Private Healthcare Information Network, insured admissions hit a record annual total in 2024, up 6% on the previous year, and that was the fourth consecutive year of growth. Spire Healthcare reported that self-pay revenue reached one third of its total UK income in 2025. Employer-sponsored health insurance is expanding as businesses use it for staff retention, and approximately 14% of UK adults now hold some form of private medical insurance, up from around 10% in 2020.

That is a significant volume of people moving through a sector whose digital infrastructure and user experiences, in many cases, were not designed to handle it.

The growth is real. The platforms and applications have not necessarily kept pace and the gap between what a private health consumer now expects from their insurer or hospital, and what they actually get when they open the app or log into the platform, is becoming impossible to ignore.

The reference point has shifted, and it did not ask permission

Think about what the average UK adult does before they arrive at a private GP appointment today. They have probably booked the slot from a mobile phone, checked their cover limits in an app, looked up the consultant on platform, and received an automated reminder with a map link. That experience is unremarkable. It is what they expect because it is what their bank, their supermarket and their gym already do.

That is the standard that private health providers are now measured against. Not against where the sector was in 2018. Against the seamless, data-informed, frictionless consumer experiences they encounter everywhere else in society.

J.D. Power’s 2025 Healthcare Digital Experience Study put a number on the gap. Commercial health plan apps scored 635 out of 1,000 for consumer experience. Wealth management apps scored 794. Property and casualty insurers scored 700. Health insurers, despite being custodians of arguably the most personal data a consumer holds, trail almost every comparable financial services category. The study found that payers failed to deliver easy access to key member data 39% of the time. When members experienced a poor digital interaction, only 27% said they were likely to use the app again.

It’s a problem of ambition versus execution in many cases.

Take NHS Scotland’s MyCare.Scot app which launched in early 2026, which is currently rated 3.5 on app store and 2.6 on Play store.

The comments tell you everything you need to know about user expectations versus production reality:

• “Shows you literally nothing. I’m on medication – it doesn’t show. I’ve had appointments – it doesn’t show. I don’t get the point of this app”
• “Very much a work in progress app. Biometrics don’t work properly. Only shows COVID and influenza vaccines. No appointments shown unless they are in NHS Lanarkshire or within dermatology according to the advisory section on the appointments page. Lists your repeat prescriptions but cannot order.
• “ If they had test results, letters, all conditions, all appointments, ability to book appointments, prescription re-ordering, you’d have a 5 star app.”

It’s important to remember that this is a public sector app and people will use mandated citizen experience if they have to. When you are running a private organisation, it is vital that you don’t make the same mistakes.

Private health organisations are operating with technology stacks and customer experience that reflect a different era of the business.

If you think about policy administration systems that were never meant to serve as consumer experience platforms. Data sitting in silos between the insurer, the hospital network, the GP referral pathway and the claims function, with no unified view of the member. Mobile apps bolted onto legacy back-ends, capable of displaying a policy number and not much else… There’s a lot to fix.

The result is a consumer experience that starts well at the point of sale and deteriorates quickly. Booking a specialist requires a phone call. Checking a pre-authorisation status requires another. Claims are still submitted on PDF forms in some cases. The member portal, if it exists, carries information that is days or weeks out of date.

Meanwhile, online appointment booking in UK healthcare rose from 6.8% of interactions in 2015 to 41% in 2024, according to Mordor Intelligence. That adoption curve shows where consumer behaviour is heading. It also shows how much catching up is left to do.

The more structural problem is data. Private health organisations sit on an extraordinary amount of it: claims histories, referral patterns, treatment outcomes, member demographics, and wearable data, where schemes have encouraged it. 

The organisations that are going to define the next decade of this market will be the ones that turn that data into a genuine platform capability rather than leaving it distributed across systems that do not speak to one another.

The B2B2C dimension could change everything

The growth in employer-sponsored PMI introduces a complexity that consumer-only models do not face.

Four out of five PMI policyholders in the UK are now covered through employer schemes. That means the insurer has two distinct relationships to manage simultaneously: one with the HR or benefits team procuring the scheme, and one with the individual employee using it.

Those two relationships have almost nothing in common in terms of what good looks like. The employer wants utilisation data, population health insights, absence management integration, and a scheme that is easy to administer at scale. The employee wants a fast, intuitive app that helps them book an appointment without navigating a policy document.

Building a platform that serves both of those experiences well, from a single underlying data layer, is genuinely difficult. It requires thinking about the architecture before thinking about the features. Most organisations in this sector have done it the other way around, adding features to platforms not designed to carry them, and accumulating the kind of technical debt that makes every subsequent improvement slower and more expensive.

What good looks like

The private health organisations that are investing properly in their technology are not doing so by developing a better app or web platform. They are also systematically reinforcing the data foundation that experiences are built upon.

A modern data platform in this context means a single, coherent view of the member that is accessible across touchpoints: the app, the member portal, the claims system, the clinical network, and the employer dashboard. It means real-time rather than batch processing, so that when a pre-authorisation is granted, the member and their GP know immediately. It means the kind of event-driven architecture that can support proactive engagement rather than just reactive queries.

On top of that foundation, application development that actually reflects how people use health services today and understands the intricacies of discrete user needs is paramount. Service design and well-informed product design is where you close the gap between expectations and experiences.

That means native mobile experiences, not responsive web views dressed up as apps. It means personalisation based on member data, not generic content. It means integrating wearable and health-tracking data where members have consented to share it, and doing something useful with it rather than storing it in a field no one reads.

An AI maturity assessment, conducted honestly rather than as a procurement exercise, will tell most private health organisations two things quickly: the data is richer than they think, and it is less usable than they need it to be.

Closing that gap is the precondition for everything else.

The window is narrowing

The private health market is not short of capital or ambition. It is short of the technical foundations to convert both into durable competitive advantage.

The organisations that move now have an opportunity to define the consumer experience standard in a market where that standard is genuinely low and visibly rising. Those that wait will find themselves closing a gap to competitors rather than opening one to them, spending more to catch up than they would have spent to lead.

The volume of people moving through the private health system is at a record level and is forecast to keep growing. The question is not whether to invest in the right technology and methodologies to deliver amazing experiences. It is whether to do it now, or later, under greater pressure, at greater cost.

That is a CTO question, a CIO question and a Design Director one. And in too many private health organisations, people are only getting around to asking it now.
