How AI Is Changing Life Insurance

Artificial intelligence is now playing a more active role across the life insurance industry, shaping how insurance companies assess risk, price cover and deliver customer service.

From our perspective, the change is less about automation in isolation and more about how decisions are made, how risk is assessed, and how consistently customer outcomes are delivered.

The impact is already visible across the value chain, though it rarely shows up in the way headline narratives imply. 

In practical terms, many of these changes are already visible in faster application decisions and more streamlined claims handling across parts of the market.

Adoption is also becoming more widespread across the sector. Industry analysis from organisations such as PwC and Deloitte suggests that a significant proportion of insurers are now using or piloting AI across areas such as underwriting, claims and customer service.

For most people, the changes are subtle, but they can still affect how quickly you get cover, how your application is assessed and how claims are handled.

Underwriting is becoming faster, but not necessarily simpler

The underwriting process is where artificial intelligence is having the most immediate impact.

Machine learning models are now used within underwriting systems to analyse large volumes of data, drawing on a wider range of data points than traditional approaches. This includes information such as age, occupation and medical disclosures, alongside electronic health records and, in some cases, behavioural signals derived from wearable devices.

This can also include third-party data, claims history and broader inputs linked to the Internet of Things, depending on how insurers structure their underwriting process.

For straightforward applications, many insurance companies can now provide decisions in minutes rather than days.

The complexity hasn’t gone away, it has shifted further into the edges of the process.

More detailed or unusual cases still require human review, particularly where information is incomplete or unclear. This is especially relevant to AI in critical illness underwriting, where medical evidence, GP reports, and applicant disclosures may need careful human interpretation.  

Similar issues can arise in AI in business protection risk assessment, where underwriting may involve both personal medical evidence and the financial position of a company. The role of the underwriter is changing, with more focus on reviewing outputs rather than assessing every application manually. 

In some cases, this supports accelerated underwriting, where decisions can be made with limited manual input for lower-risk applicants.

For customers, this often means quicker decisions where circumstances are straightforward, but similar levels of scrutiny where they are not.

Risk assessment is becoming more granular

Rather than placing applicants into broad groups, insurers are starting to assess risk in more detail using Big Data and predictive modelling techniques.

Models trained on large datasets can identify patterns that would not be visible through traditional underwriting alone. In areas such as critical illness cover, this can lead to more consistent outcomes where decisions have historically varied.

These approaches form part of wider risk modelling frameworks used across the life insurance business.

Pricing becomes more accurate, and reliance on cross-subsidy between policyholders starts to reduce. At the same time, this introduces new considerations. If models become too refined, certain groups could face higher premiums or more restrictive terms.

From an FCA perspective, expectations are clear. Insurers must be able to show that risk assessment remains fair, that decisions can be explained, and that customer outcomes meet regulatory requirements.

For customers, this means assessments may feel more tailored, but also more dependent on individual circumstances.

Claims processing is becoming more efficient, but scrutiny remains

AI-led claims processing is already used across much of the insurance industry, although it tends to work behind the scenes.

Automation helps insurers with claims triaging, validating documentation and identifying inconsistencies early in the claims process. Natural language processing supports the review of written submissions, while fraud detection engines are used to identify unusual patterns in claims handling.

In straightforward cases, claims handling is faster, and delays are reduced, which has a direct impact on customer experience and customer satisfaction.

Some industry estimates suggest that, in certain lower-complexity cases, AI-supported processes have reduced claims handling times compared to traditional manual approaches.

Where claims become more complex, insurers still rely on manual review. This is particularly important where claim values are high or where information is incomplete. Decisions in these situations require a level of judgement that automated systems alone cannot provide.

Most insurers are not trying to automate the entire claims process. The focus is on improving efficiency while maintaining appropriate oversight.

Customer engagement is shifting, but advice still matters

Customer interactions are changing, particularly at the early stages of the journey.

Virtual assistants, AI-driven chatbots and virtual agents are now handling a growing share of routine queries. Many of these tools are powered by large language models and Natural Language Processing, allowing insurers to respond more effectively to customer interactions.

Across the market, customer service is one of the most widely adopted use cases, with a significant proportion of insurers using AI-driven tools to handle routine enquiries and improve response times.

For customers, this can improve customer engagement and make it easier to access information quickly.

The line between information and advice is still very much there.

While artificial intelligence can support policy recommendations based on inputs, it does not account for wider personal or financial circumstances in the same way an adviser can. Life insurance decisions often involve factors such as family needs, business protection and long-term planning.

For customers, this means it is often easier to access information, but still important to ensure that cover is structured appropriately.

Operational efficiency is improving, but governance is tightening

Across the insurance sector, artificial intelligence is helping improve efficiency.

Processes such as underwriting, claims processing and customer service can be handled more quickly, reducing delays and manual intervention. For insurers, this supports more scalable and consistent operations. 

At the same time, industry commentary suggests many firms are deploying these technologies cautiously, often within controlled or “sandbox” environments to manage risks around data quality, bias and explainability.

Alongside this, expectations around regulatory compliance are increasing.

In the UK, this sits alongside oversight from the Financial Conduct Authority, as well as frameworks such as the General Data Protection Regulation. Developments are also monitored by bodies including the Information Commissioner's Office and the Prudential Regulation Authority.

Insurers must be able to explain how decisions are made, where data is sourced and how outcomes can be justified. This is particularly important where decisions affect pricing or claims.

As a result, firms are cautious about relying on systems that cannot be clearly explained. Transparency remains essential.

Where AI is overhyped

Some applications of artificial intelligence are delivering less than expected.

Generative AI and large language models are useful in customer interactions and internal workflows, but their role within underwriting or risk assessment remains limited without reliable data and validation.

The idea of fully automated life insurance journeys is often discussed, but in practice remains constrained. Regulatory requirements and the need for oversight mean that more complex cases still require human involvement.

In many cases, targeted improvements are delivering more value than broader transformation programmes.

What this means for life insurance going forward

Artificial intelligence is not replacing the fundamentals of life insurance. It is refining how those fundamentals are applied.

The underwriting process is speeding up, which can lead to quicker decisions for some applicants.

Risk assessment is becoming more detailed, meaning outcomes may be more closely aligned to individual circumstances.

Customer experience and customer satisfaction are improving as processes become more efficient and easier to navigate.

For customers, the most important point is that the basics still matter. Choosing the right level of cover, understanding how policies are structured and ensuring your needs are properly reflected remain unchanged.

For some customers, it may also be worth reviewing whether extra protection is needed alongside life insurance, particularly where illness or loss of income would create a financial gap.

If anything, as processes become more automated, taking the time to get the right advice becomes more important, particularly where cover needs to reflect more complex circumstances.

Progress is gradual rather than abrupt. Regulation, trust and the realities of implementation will continue to shape how these changes develop.
