UK Income Protection Insurance Claim Denied? How to Appeal

Income protection (IP) insurance — sometimes called permanent health insurance (PHI) — replaces a portion of your income if you cannot work due to illness or injury. It is one of the most valuable financial products available to UK workers, yet IP claims are routinely denied by insurers who challenge whether policyholders truly meet the definition of incapacity, or who cite non-disclosure, exclusions, or policy technicalities.

If your income protection claim has been refused, this guide explains why it may have happened and what you can do to fight back.

Why UK Income Protection Claims Are Denied

Definition of Incapacity Not Met

The definition of "unable to work" varies significantly between policies. There are two main types:

• Own occupation: You cannot perform the specific duties of your own job. This is the most generous definition and is typically found in higher-quality IP policies.
• Any occupation (or suited occupation): You are only covered if you cannot perform any job — or any job for which you are reasonably suited by training, education, and experience. This is a much harder test to meet.

Insurers frequently deny claims by arguing that, while you cannot do your exact job, you could perform some other type of work. If your policy uses a broad incapacity definition, this is especially common.

Mental Health Claim Disputes

Mental health conditions — including depression, anxiety, and burnout — account for a significant proportion of IP claims and a disproportionate share of denials. Insurers may dispute whether the severity of the condition truly prevents work, or may invoke exclusions for conditions that pre-dated the policy.

Pre-existing Condition Exclusions

If you had symptoms, received treatment, or took medication for a condition before applying for IP insurance, the insurer may exclude claims arising from that condition, either for a set period or permanently.

Non-Disclosure

If the insurer believes your application contained inaccurate or incomplete health information, it may deny the claim and potentially void the policy. Non-disclosure disputes are particularly common where applicants did not disclose mental health treatment, musculoskeletal problems, or previous GP consultations.

Deferred Period Issues

Most IP policies have a deferred period — a waiting period (typically 4, 13, 26, or 52 weeks) before payments begin. If you return to work during the deferred period — even briefly — the insurer may argue the clock resets.

Failure to Follow Medical Advice

Some IP policies include provisions allowing the insurer to reduce or refuse payments if you do not follow reasonable medical advice or engage with treatment or rehabilitation.

Your Rights Under FCA Rules

Your income protection insurer is regulated by the FCA. Under FCA DISP:

• Complaints must be acknowledged within five business days
• A final response must be issued within eight weeks
• You can refer unresolved disputes to the Financial Ombudsman Service (FOS) within six months of the final response

The FOS regularly rules on IP disputes, particularly around the definition of incapacity and non-disclosure handling. Its decisions are binding on insurers.

How to Challenge a Denied IP Claim

Step 1: Understand the Basis of Denial

Request the denial letter in writing if you haven't received one. Identify:

• Which incapacity definition the policy uses
• The specific reason the insurer claims you don't qualify
• Whether a non-disclosure allegation is involved

Step 2: Gather Medical Evidence

Your GP and any treating specialists should provide letters:

• Confirming your diagnosis and the severity of your condition
• Stating that you are unable to perform your occupational duties
• Describing any restrictions and limitations on your daily functioning

For mental health claims, include letters from psychiatrists, psychologists, or CBT therapists confirming ongoing treatment and functional impairment.

Step 3: Challenge the Occupational Assessment

If the insurer's decision is based on an occupational or functional assessment:

• Request a copy of the report
• Check whether the assessor had the appropriate clinical expertise
• Obtain a counter-opinion from your treating clinician
• Identify any factual errors in the assessment

Step 4: Submit a Formal Complaint

Write a formal complaint to the insurer's complaints team, including:

• A clear statement of why the denial is incorrect
• Medical evidence from your treating clinicians
• Counter-arguments to the insurer's specific denial grounds
• Reference to the relevant policy wording

Step 5: Escalate to the FOS

If unsatisfied with the response, refer to the FOS within six months. The FOS takes a balanced view of IP disputes and frequently overturns denials based on overly strict application of incapacity definitions.
