Income protection insurance is a valued workplace benefit in the UK, designed to pay a proportion of your salary if illness or injury stops you working. But understanding how it fits with sick pay, deferred periods, medical evidence and return-to-work plans can be confusing. Here’s what to look out for, practical steps to take, and how to avoid common pitfalls.

How Income Protection Works Alongside Sick Pay

Most workplace income protection policies do not pay out immediately. Instead, there’s a deferred period—typically 13, 26 or 52 weeks—before benefits start. This is to ensure the policy only kicks in after your employer’s sick pay (and Statutory Sick Pay) runs out.

For example, if your employer provides 6 months’ full sick pay and your policy has a 26-week deferred period, you won’t receive income protection payments until your sick pay ends. If you return to work before the deferred period is up, you won’t receive any payout.

Messy Example: Deferred Period Confusion

Sarah works for a medium-sized firm and is signed off work after surgery. Her employer offers 3 months’ full sick pay. Her income protection policy has a 26-week (6 month) deferred period. After her sick pay ends, she expects the insurance to pay out, but is told she must wait another 3 months. She hadn’t realised the deferred period was longer than her sick pay, leaving her with a gap in income.

This situation is common. Always check the length of your sick pay and the deferred period on your policy—they rarely match up exactly.

Medical Evidence and Claiming

To make a claim, you’ll need to provide medical evidence—usually a fit note from your GP or specialist, and sometimes ongoing updates. Insurers may ask for:

  • Medical records and reports

  • Details of your diagnosis and treatment plan

  • Confirmation you’re unable to perform your normal job duties

Keep copies of all medical notes, letters, and emails. If your claim is delayed or denied, you may need to show exactly what you provided and when.

Return-to-Work Plans

Most income protection insurers expect regular updates on your health and may ask for a return-to-work plan. This could include:

  • Phased return dates

  • Adjustments or reduced hours

  • Occupational health assessments

Some policies reduce or stop payments as soon as you’re able to return, even part-time. Clarify with your HR team and insurer how your policy treats phased returns or light duties.

Key Questions to Ask

  • What is the deferred period on our workplace policy?

  • How does this line up with my contractual and statutory sick pay?

  • What medical evidence will I need to provide, and how often?

  • How are phased returns or part-time work treated?

  • Are there exclusions for pre-existing or chronic conditions?

  • How will any payments be taxed?

Ask your HR team or broker for a copy of the full policy schedule and any underwriting terms. Get all exclusions and key dates in writing. If you’re unsure, ask for clarification—no question is too basic.

Tax and Reporting: What to Watch

Employer-paid income protection is usually classed as a benefit in kind. Unless an exemption applies, you’ll probably pay tax on the value of premiums. Employers must report this to HMRC—currently via P11D, but HMRC is phasing in mandatory payrolling of certain benefits (including medical benefits) from April 2027. Check with your payroll team how your benefit is reported and whether payrolling will affect you.

Income protection payouts may also be taxable, depending on who paid the premiums and how the policy is structured. Ask your HR or payroll team for written confirmation of how any payout would be taxed if you claim.

Common Pitfalls and How to Avoid Them

  • Deferred period mismatch: Know the gap between your sick pay and when insurance starts.

  • Missing evidence: Keep all medical notes, fit notes, and correspondence.

  • Policy exclusions: Ask for a full list of exclusions and how pre-existing conditions are handled.

  • Tax surprises: Confirm with payroll how premiums and payouts are treated.

What to Do if a Claim is Denied

  1. Ask the insurer for a full written explanation of the decision, referencing policy terms.

  2. Escalate as a formal complaint. Insurers have up to 8 weeks to respond.

  3. If unresolved, refer to the Financial Ombudsman Service, which can handle disputes about private medical and dental insurance, including pre-existing condition and exclusion issues.

Keep a record of all communications and evidence. This will help if you need to escalate your case.
