In the vast UK protection market, two names stand out for their global scale and comprehensive offerings: Zurich and Aviva Protection (formerly AIG Life).

Both are titans of the insurance world, trusted by millions. But when it comes to protecting your family or your business in 2025, which one truly leads the pack? Is the Swiss precision and heritage of Zurich the right fit for you, or does the innovative, value-packed approach of Aviva's former AIG Life protection business better suit your needs?

This definitive guide will dissect, compare, and analyse every crucial aspect of their offerings. We’ll go beyond the marketing brochures to give you a clear, unbiased view, helping you make an informed decision for your future.

WeCovr compares these two global players in the UK life market

At WeCovr, we work with leading insurers like Zurich and Aviva, including legacy AIG Life policies, every single day. Our expertise allows us to see beyond the surface-level details and understand the real-world differences that matter to you. Let's introduce the contenders.

Zurich: Founded in 1872, Zurich is a Swiss powerhouse with a formidable global presence and a long, stable history. In the UK, they are known for their high-quality, comprehensive products, strong financial ratings, and a commitment to sustainability. Zurich represents reliability and a tradition of excellence.

Aviva Protection UK (formerly AIG Life): AIG Life Limited was the UK protection arm of the American International Group. Established in the UK in 2015 after acquiring Ageas Protect, it quickly became a major disruptive force in the market. Aviva acquired AIG Life in 2024 and rebranded it in February 2025 as Aviva Protection UK Limited. The legacy AIG Life policies are now managed by Aviva and remain known for their innovative added-value benefits and flexible underwriting philosophy.

Both are excellent providers, but they cater to slightly different priorities and customer profiles. This comparison will explore those nuances in detail.

At a Glance: Zurich vs Aviva (formerly AIG Life) Key Features (2026)

Before we dive deep, here’s a high-level summary of how these two insurers stack up.

Core Protection Products: A Head-to-Head Analysis

The foundation of any insurer is the quality of its core products. Let's break down how Zurich and Aviva (formerly AIG Life) compare across life insurance, critical illness cover, and income protection.

Life Insurance

Life insurance provides a lump sum or regular income to your loved ones if you pass away during the policy term. It’s designed to clear debts like a mortgage, cover funeral costs, and provide for your family's future living expenses.

Zurich Life Protection Zurich's offering is a classic, robust term life insurance plan. It’s flexible and can be tailored to meet a wide range of needs.

• Cover Types: Offers Level Term Assurance (payout stays the same), Decreasing Term Assurance (payout reduces, ideal for repayment mortgages), and Family Income Benefit.
• Term Lengths: Policies can run from 1 to 50 years.
• Cover Amount: High maximum cover levels available, subject to underwriting.
• Joint Life: Available on a 'first death' basis, meaning the policy pays out on the first death and then ends.
• Multi-Policy Discount: A key benefit. If you take out more than one policy with Zurich (e.g., life and income protection), you can receive a discount, making a comprehensive protection package more affordable.

Aviva (formerly AIG Life) Term Assurance Aviva (formerly AIG Life) provides a highly competitive and feature-rich term life insurance product.

• Cover Types: Also offers Level, Decreasing, and Family Income Benefit options.
• Term Lengths: Flexible terms available to match your needs.
• Instant Life Cover: For non-medical applications, Aviva (formerly AIG Life) can often put cover in place immediately, providing peace of mind from day one.
• Joint Life: Available on a 'first death' basis.
• Key Feature: Every Aviva (formerly AIG Life) policyholder gets free access to their Smart Health service, a significant added benefit we'll explore later.

Life Insurance Comparison Table

Verdict: Both offer excellent, flexible term life insurance. Zurich's multi-policy discount is a strong incentive for those buying a package of cover. Aviva's former AIG Life inclusion of Smart Health provides immediate, tangible value from the moment the policy starts.

Critical Illness Cover (CIC)

Critical Illness Cover pays out a tax-free lump sum if you are diagnosed with one of a specific list of serious medical conditions. This money can be a lifeline, helping you cover lost income, pay for private treatment, or adapt your home.

The quality of a CIC policy often comes down to the number of conditions covered and the clarity of the definitions.

Zurich Critical Illness Cover Zurich provides a comprehensive CIC policy with a strong focus on core conditions and support.

• Conditions Covered: Zurich covers a robust list of full payment conditions (typically around 40-50, including all ABI standard definitions) and a number of additional/partial payment conditions.
• Children's Cover: Automatically included, offering a significant level of cover for your children at no extra cost. It is often praised for its comprehensive nature.
• Support Services: Policyholders gain access to Zurich Support Services, providing practical and emotional support from nurses, counsellors, and other professionals.

Aviva (formerly AIG Life) Critical Illness Cover Aviva's former AIG Life CIC is known for its extensive list of covered conditions and its forward-thinking approach.

• Conditions Covered: Aviva (formerly AIG Life) boasts one of the most comprehensive lists on the market, covering over 80 conditions for full payment and an additional 40+ for partial payment. They have a reputation for covering conditions that other insurers may not.
• Children's Cover: Automatically included and is also highly comprehensive.
• Enhanced Definitions: Aviva (formerly AIG Life) often uses 'ABI+' definitions, meaning their criteria for a payout can be more generous than the industry standard.
• Smart Health: Again, the Smart Health service is a huge bonus here, providing second medical opinions which can be invaluable following a serious diagnosis.

Critical Illness Cover Comparison Table

Verdict: For sheer breadth of coverage, Aviva (formerly AIG Life) often has the edge with its extensive list of conditions. This can provide greater peace of mind. However, Zurich's policy is extremely robust and high-quality. The choice may come down to which provider's definitions better cover your specific health concerns. An expert adviser at WeCovr can help you compare these complex documents.

Income Protection (IP)

Income Protection is arguably the one policy every working adult should consider. It pays a regular, tax-free monthly income if you're unable to work due to illness or injury. It's a replacement for your salary that can last until you recover or reach retirement age.

Zurich Income Protection Zurich offers a flexible and reliable IP product designed to provide a secure safety net.

• Incapacity Definition: Typically offers an 'own occupation' definition for many professions, which is the gold standard. This means the policy pays out if you are unable to do your specific job.
• Deferment Periods: A wide range from 4, 8, 13, 26, to 52 weeks, allowing you to align the policy with your employer's sick pay.
• Payment Period: Can choose short-term (e.g., 2 years per claim) or long-term (pays out until retirement age).
• Support: Includes rehabilitation and back-to-work support to help you recover and return to employment.

Aviva (formerly AIG Life) Income Protection Aviva's former AIG Life IP product is competitive and comes with several claimant-friendly features.

• Incapacity Definition: Also strongly focuses on the 'own occupation' definition, ensuring a fair assessment at the point of claim.
• Deferment Periods: Offers a full range of deferment periods to suit both employed and self-employed individuals.
• Payment Period: Offers both short-term and long-term (full-term) benefit options.
• Trauma Benefit: Includes a lump-sum payment for specific injuries (e.g., fractures, ligament tears), which can provide immediate financial help without affecting the main income benefit.

Income Protection Comparison Table

Verdict: Both providers offer first-class income protection. Aviva's former AIG Life included Trauma Benefit is a nice touch that adds extra value. Zurich's reputation for excellent rehabilitation support is a significant plus. The best choice often depends on your occupation and the specific terms offered after underwriting.

Added-Value Benefits & Wellness Support: Beyond the Payout

In 2025, a protection policy is about more than just a cheque at the worst time in your life. Insurers now compete on the day-to-day value they provide, helping you and your family live healthier lives.

Zurich Support Services

Available to all Zurich policyholders and their families, this is a comprehensive support network designed to help with life's challenges. It includes:

• Counselling: Access to a network of counsellors for face-to-face or telephone support for issues like stress, anxiety, or bereavement.
• 24/7 Helpline: Manned by BACP-accredited counsellors.
• Nurse Support: Specialist nurses can provide guidance and support following a diagnosis or during a difficult health period.
• Second Medical Opinion: While not as integrated as Aviva's former AIG Life, options for seeking a second opinion are available through their partners.

This service provides real, tangible support that can be used at any time, not just at the point of a claim.

Aviva's former AIG Life Smart Health

This is Aviva's former AIG Life flagship feature and a genuine game-changer in the UK protection market. It is provided at no extra cost to all Aviva (formerly AIG Life) policyholders, their partners, and their children up to age 21. It's a suite of six services accessible via a simple app or phone call:

1. 24/7 Digital GP: Get a phone or video consultation with a UK-based GP anytime, anywhere. This can save weeks of waiting for an NHS appointment. Prescriptions can be sent directly to your local pharmacy.
2. Best Doctors® (Second Medical Opinion): If you or a family member receive a diagnosis, you can have your case reviewed by a world-leading specialist to confirm the diagnosis and recommend the best treatment plan. This is an incredibly powerful tool.
3. Mental Health Support: Access to up to four therapy sessions per condition, per year. This can be used for a wide range of issues from stress to more complex conditions.
4. Fitness & Nutrition Plans: Personalised programmes designed by experts to help you achieve your health and wellness goals.
5. Online Health Check: A comprehensive online questionnaire that provides a personalised health report and advice.
6. Expert Case Management: For complex medical cases, this service helps you navigate the healthcare system.

The value of Smart Health cannot be overstated. For a family, the ability to see a GP instantly at 3 am when a child is ill is worth its weight in gold.

The Claims Experience: Putting Promises to the Test

A policy is only as good as the insurer's willingness and ability to pay claims. Both Zurich and Aviva (formerly AIG Life) have outstanding and transparent records.

Zurich Claims Statistics Zurich consistently publishes its claims data, demonstrating a strong commitment to paying out.

• Latest Reported Figures (2023):
  • Life Insurance (illustrative): Paid 98% of claims, totalling over £468.9 million.
  • Critical Illness (illustrative): Paid 93% of claims, totalling £248.8 million.
  • Income Protection: Paid 93% of claims.
• The Human Touch: Zurich is known for its empathetic and efficient claims process, often assigning a dedicated claims assessor to see a case through from start to finish.

Aviva (formerly AIG Life) Claims Statistics Aviva (formerly AIG Life) is equally proud of its payout record and provides detailed reports on its performance.

• Latest Reported Figures (2023):
  • All Claims: Paid 99% of all claims (Life, CI, and IP).
  • Total Paid (illustrative): Over £735 million paid out to more than 8,600 claimants.
  • Claims Support: Aviva (formerly AIG Life) provides exceptional support, including their Claims Support Fund, which can offer immediate financial assistance for things like travel to hospital appointments.

Why are claims declined? It's important to note that the small percentage of claims declined by any insurer are almost always due to two key reasons:

1. Non-disclosure: The applicant was not truthful about their health, lifestyle (e.g., smoking), or occupation on the application form.
2. The definition was not met: For a critical illness claim, the condition diagnosed did not meet the specific definition in the policy wording.

This is why absolute honesty during application and understanding the policy documents are crucial. Working with a broker like WeCovr helps ensure your application is accurate and you understand the cover you're buying.

Underwriting Philosophy and Target Audience

Underwriting is the process insurers use to assess your risk and decide the terms of your policy.

Zurich's Approach Zurich is often seen as a premier choice for professionals and those with straightforward health profiles. Their underwriting is thorough and based on a wealth of historical data. They have a strong online application process that can deliver instant decisions for many applicants. While they will consider more complex cases, their sweet spot is often the standard to low-risk applicant seeking high-quality, comprehensive cover.

Aviva's former AIG Life Approach Aviva (formerly AIG Life) has a reputation for being more flexible and innovative in its underwriting. They are often willing to consider applicants who might be rated or declined elsewhere. This can include:

• Certain pre-existing medical conditions.
• Higher-risk occupations.
• Those with a more complex financial or lifestyle background.

Their use of technology aims to make the journey smoother for a wider range of people. This doesn't mean they accept everyone, but their approach can be more solution-oriented.

Who are they best for?

• Choose Zurich if: You value brand heritage, financial strength, and a high-quality, traditional insurance product. Their multi-policy discount makes them an excellent choice if you're building a complete protection portfolio (e.g., life, CI, and IP).
• Choose Aviva (formerly AIG Life) if: The day-to-day wellness benefits of Smart Health are a major draw for you and your family. You want the most extensive critical illness cover available. You may have a slightly more complex health profile and need a flexible underwriter.

Specialist Cover for Business Owners & Directors

Both Zurich and Aviva (formerly AIG Life) are major players in the business protection market, offering vital cover for company directors, business owners, the self-employed, and freelancers.

Key Person Insurance: Imagine your business's most vital employee—perhaps a top salesperson or a technical genius—is diagnosed with a critical illness and can't work. Key Person Insurance provides a lump sum to the business to cover lost profits, recruit a replacement, or manage debts during this difficult period. Both Zurich and Aviva (formerly AIG Life) offer excellent, flexible Key Person policies.

Relevant Life Cover: This is one of the most tax-efficient ways for a limited company to provide life insurance for its employees, including directors.

• The company pays the premiums.
• Premiums are typically an allowable business expense.
• It's not treated as a P11D benefit-in-kind for the employee.
• The payout goes directly to the employee's family, free of inheritance tax. Both insurers offer competitive Relevant Life Plans.

Executive Income Protection: Similar to a Relevant Life Plan, this is an income protection policy paid for by the company for an employee or director. It's a highly valued benefit that protects an individual's income in a tax-efficient manner for the business. Zurich and Aviva (formerly AIG Life) both provide strong offerings in this space.

Considering Other Important Protection Products

While Life, CI, and IP are the cornerstones, Zurich, Aviva (formerly AIG Life), and other insurers offer further solutions.

• Family Income Benefit (FIB): Instead of a single lump sum, this pays out a regular, tax-free monthly or annual income until the end of the policy term. It's often more affordable than a lump-sum policy and can be easier for a family to manage, replacing the deceased's lost salary.
• Personal Sick Pay: These are typically short-term income protection policies, often with a 1 or 2-year payment period per claim. They are popular with tradespeople and those in riskier jobs who need a simple, affordable safety net against short-to-medium term absences from work.
• Gift Inter Vivos Cover: A clever tool for Inheritance Tax (IHT) planning. If you gift a large sum of money or an asset, it only becomes fully exempt from IHT if you survive for 7 years. A Gift Inter Vivos policy is a life insurance plan that runs for 7 years, with a payout that decreases in line with the IHT liability, protecting your beneficiaries from an unexpected tax bill.
