Medical Underwriting at Renewal: Managing Increasing Premiums on Protection Policies

Many protection insurance policies — particularly group protection schemes, individual income protection plans, and reviewable whole of life policies — carry premiums that the insurer can review and revise at specified intervals. For policyholders who bought cover on the basis of an initial premium, the prospect of a substantial increase at review can be alarming. For those who have developed health conditions since inception, the fear of being re-underwritten — and finding that new cover would be unavailable — compounds the anxiety.

This guide explains how reviewable premiums work, what drives premium increases, and the options available to manage escalating costs without unnecessarily surrendering essential cover.

As of 2026, the specific terms of reviewable protection policies vary significantly between insurers and product types. Always read your policy schedule and terms and conditions carefully. This guide is informational and does not substitute for advice from a regulated protection specialist.

Guaranteed vs. Reviewable Premiums: The Fundamental Distinction

Guaranteed Premiums

A policy with guaranteed premiums fixes the premium at inception for the full policy term. The insurer bears the risk that actual mortality or morbidity experience is worse than they expected when pricing the policy — they cannot pass that risk back to the policyholder through a premium increase.

Guaranteed premiums are typically higher at inception than their reviewable equivalents, because the insurer builds a margin into the pricing to cover the uncertainty. However, they offer complete predictability — particularly important for long-term plans used in retirement or IHT planning, where the policyholder needs to budget for premiums over decades.

Reviewable Premiums

A policy with reviewable premiums allows the insurer to revise the premium at specified review dates — typically every 5 or 10 years. At each review, the insurer can increase the premium based on:

• The insurer's revised claims experience — if the insurer has paid more claims than expected across the risk pool, premiums for all policyholders may increase
• Updated mortality or morbidity tables — as the insured population ages, statistical mortality increases; the premium must reflect the current expected cost
• The individual's age — the older the policyholder, the higher the underlying risk; reviewable premiums capture this age-related increase
• Changes in reinsurance costs — insurers typically reinsure large or long-tail risks; if reinsurance pricing increases, the insurer may pass this through to policyholders

At initial inception, reviewable policies are typically quoted with a lower premium than the guaranteed equivalent for the same sum assured. This makes them superficially attractive — but the long-term cost, particularly for policies intended to run to age 70 or 80, can significantly exceed a guaranteed premium policy placed at the same age.

How Much Do Premiums Typically Increase at Review?

There is no single answer — it depends on the insurer, the policy type, and the claims experience of the relevant risk pool. However, broad market experience suggests:

• Early reviews (5 to 10 years after inception): Modest increases, often in line with medical inflation (5% to 15%)
• Mid-policy reviews (10 to 20 years after inception): Increases of 20% to 50% are common as the insured population ages
• Later reviews (20+ years after inception, particularly above age 60): Increases of 50% to 200% or more are not uncommon for individual reviewable whole of life policies

For group schemes (group income protection, group critical illness), the insurer reviews the scheme as a whole and applies a group premium adjustment — which may be lower (if the group has had good claims experience) or higher (if there have been multiple claims).

Reviewable Whole of Life Policies and IHT Planning

The most significant premium review risk for individual policyholders arises in reviewable whole of life policies used for IHT planning. These policies are designed to run indefinitely — the premium is paid until death — but reviewable pricing means the premium can escalate dramatically in later life.

A policy placed at age 55 with a reviewable premium of £600 per month for a £500,000 sum assured might be reviewed at age 65 to £900 per month, reviewed again at 75 to £1,500 per month, and reviewed at 85 to £3,000 or more per month. A client on a fixed retirement income may find these escalating premiums simply unaffordable.

Options when reviewable premiums become unaffordable:

1. Reduce the sum assured — the insurer will reduce the sum assured proportionately if the policyholder cannot afford the increased premium. The policy continues, but provides less cover.

2. Premium holiday (suspension) — some whole of life policies allow a temporary suspension of premiums, with the policy continuing on a reduced paid-up basis. This is not available on all policies.

3. Surrender and replace — surrender the reviewable policy and take out a new guaranteed premium policy. However, this typically requires fresh medical underwriting. If the policyholder has developed health conditions since the original policy was placed, new cover may be unavailable, heavily loaded, or more expensive than the reviewed premium. Surrender before replacement is therefore inadvisable.

4. Accept the reviewed premium — if the policy serves a genuine IHT planning objective and the sum assured is still needed, accepting the higher premium may be the most practical option, particularly where fresh medical underwriting is unattractive.

5. Review the underlying IHT plan — at the same time as a premium review, revisit the overall estate planning picture. Has the IHT liability changed (through asset disposal, gifting, or changes in nil-rate bands)? A lower required sum assured may make the reviewed premium more affordable.

Medical Underwriting at Renewal for Group Schemes

For employer-sponsored group protection schemes (group life, group income protection, group critical illness), the renewal process is different from individual policy reviews.

What Happens at Group Scheme Renewal

The insurer reviews the scheme annually at renewal date. The review considers:

• Claims experience: How many claims have been paid during the year? What was the total claims cost?
• Changes in the membership profile: Has the average age increased? Has the number of members changed significantly?
• External pricing factors: Have reinsurance rates changed? Has the general claims environment in the market shifted?

The insurer then quotes a revised premium for the coming year. Good claims experience often results in modest increases or even premium reductions. Poor claims experience — particularly for a small scheme with a large claim — can result in very significant premium increases.

Managing Group Scheme Renewals

Don't accept the first quotation: Renewal quotations can be negotiated, particularly for larger schemes. If the incumbent insurer's renewal terms are unfavourable, market the scheme to alternative insurers. Many employers do not do this, and pay more than necessary as a result.

Challenge the claims loading: If the premium increase is driven by a specific large claim, discuss with the insurer whether the claim was exceptional and unlikely to recur, and whether they can moderate the loading over multiple renewal years rather than applying the full increase in year one.

Review the scheme design: If premiums are increasing due to high income protection claims, review whether the scheme design is driving excessive claims — for example, a very short deferred period may be encouraging early claims that could have been managed through sick pay instead.

Consider self-insurance (captive): For large schemes (typically 200+ lives), moving to a partially self-insured or captive model can reduce the volatility of premiums and improve long-term cost efficiency, particularly for schemes with good historic claims experience.

Individual Protection at Renewal: Income Protection

For individually placed income protection policies on a reviewable basis, the renewal review follows a similar structure to whole of life: the insurer revises the premium at the review date, based on the policyholder's current age and the insurer's revised morbidity assumptions.

Key difference from whole of life: Income protection has a defined policy term (typically to retirement age — UK State Pension age is rising from 66 to 67 on a phased basis between April 2026 and March 2028). The premium escalation risk is therefore bounded — it increases over the policy term but stops at the end of the term, rather than continuing indefinitely.

For individual income protection policies, switching from reviewable to guaranteed premiums is often worth considering at the time of a premium review — particularly if the policyholder has no significant health changes that would make fresh underwriting unattractive. The premium increase for the move to guaranteed terms is often moderate if the policyholder is still relatively young and in good health.

Medical Re-underwriting Risk When Switching Policies

The greatest risk associated with attempting to manage increasing premiums by switching insurers is the requirement for fresh medical underwriting. Any health conditions developed since the original policy was placed — managed blood pressure, diabetes, a cancer history, cardiac events — will be underwritten afresh. The new insurer may:

• Offer standard terms (if conditions are well-controlled and considered low-risk)
• Apply a loading
• Exclude specific conditions
• Decline the application

If the original policy is surrendered before the new policy is confirmed, the policyholder may find themselves uninsured. Never surrender or lapse an existing policy until a replacement has been confirmed in writing by the new insurer.

For policies with guaranteed insurability options (GIOs) — which allow the sum assured to be increased without medical underwriting at specified life events — exercise these options proactively while in good health, rather than waiting until a health event makes the option more valuable but potentially unavailable.

Planning Ahead: Buying on Guaranteed Terms

The most effective way to manage premium review risk is to buy on guaranteed terms from the outset — even if the guaranteed premium is higher at inception. The premium predictability over a 20 or 30-year horizon typically makes the guaranteed option cheaper in present value terms for policies intended to run to advanced age.

For protection policies that are unlikely to run beyond 15 to 20 years (for example, an income protection policy taken out in mid-career that runs to state pension age), reviewable premiums may be acceptable — the review risk is limited to one or two review dates.

For whole of life policies used in IHT planning — intended to run indefinitely until death, potentially decades hence — guaranteed premiums are strongly preferable unless cost is a significant constraint.
