When an insurer pays less than the headline loss, identify every deduction separately. "The policy only pays X" can hide several different mechanisms, each of which needs its own contractual and factual justification.
Insurance disputes are rarely decided by one sentence in the policy. The wording, what the insurer asked, what happened, the evidence and the reason given for the decision all matter. Keep those questions separate so the complaint stays testable.
Key points
- An excess is the amount the consumer bears under the policy; it is different from a policy limit or valuation reduction.
- Some policies have more than one excess, but the insurer should apply the wording to the correct insured event and claim.
- Co-payments and percentage contributions are common in pet or medical insurance and need to be calculated from the actual policy terms.
- Underinsurance, depreciation and betterment are separate concepts and should not be bundled into an unexplained net figure.
Diagnosis
First: what exactly has happened?
Start by identifying the actual dispute. Similar-looking insurance complaints can turn on very different rules.
| What happened? | What to check first |
|---|---|
| A compulsory and voluntary excess are both deducted | Check the schedule and whether both apply cumulatively. |
| Two excesses are deducted from one incident | Ask whether the policy treats this as one claim/event or multiple insured sections. |
| A policy limit caps the claim | Check the exact limit: per item, per event, per year or overall sum insured. |
| The insurer deducts a percentage contribution | Check age-related co-payments, veterinary contribution clauses or medical cost-sharing terms. |
| The insurer says the consumer will be "better off" after repair | Ask what specific betterment is alleged and whether a deduction is actually provided for. |
Build a gross-to-net calculation
Start with the gross accepted loss. Then list every deduction in order: excess, policy limit, co-payment, depreciation, underinsurance or any other adjustment. Ask the insurer to confirm the clause for each. This turns an opaque offer into something testable.
One incident can involve several policy sections
A household escape-of-water event might involve buildings, contents and alternative accommodation. Whether more than one excess is fair depends on the wording and how the policy structures the cover. Do not assume either one excess or multiple excesses without reading the schedule.
Policy limits must be read precisely
Limits can apply per item, category, incident, claim, condition or policy year. Check whether the insurer has applied the correct limit and whether it is aggregating losses that the wording treats separately.
Co-payments and age-related contributions
Pet and private medical policies often use percentage contributions or treatment limits. Ask for the calculation and the policy year to which it relates. A renewal can change the excess or contribution, so use the wording in force when the insured event occurred.
Underinsurance is not just another excess
Where a home insurer applies an average clause or reduces a claim because the sum insured was too low, the fairness of the original questions can matter. Treat this as a valuation / misrepresentation issue, not merely a fixed deduction.
Depreciation and indemnity
Some cover replaces old with new; other cover pays the value immediately before loss. Before arguing about a depreciation percentage, establish which basis the policy actually promises.
What to say next
Ask for a settlement statement showing the gross accepted amount, every deduction, the clause relied on and the calculation. If the firm cannot explain how it reached the net payment, that is a complaint point in itself.
Who is responsible for explaining deductions?
The insurer should be able to show how the policy and claim calculation produce the net payment. If a broker sold a policy with an unexpectedly high excess or limit and that was not adequately explained, the broker or seller may face a separate sales complaint.
Where a repairer or vet collects the excess directly, that does not change the underlying policy question. Ask the insurer to confirm the amount and basis.
What remedy is realistic?
If a deduction was wrongly applied, ask for the withheld amount plus any appropriate interest or directly caused loss. If the issue is that the policy was sold with unsuitable limits or a material exclusion was misrepresented, the remedy may instead involve a mis-selling assessment and putting you in the position you would have been in with suitable cover.
Important exceptions and edge cases
Excesses can vary by claim type, location, insured person, pet age or voluntary choice. A renewal can change them. Never rely on last year's schedule.
Where several losses arise from one event - for example one escape-of-water incident damaging both buildings and contents - the number of excesses can depend on policy structure. Ask the insurer to explain why it treats the losses as separate claims if it applies more than one.
Common insurer responses - and what they do not necessarily prove
| The insurer says | What to test |
|---|---|
| "It is the standard excess." | Check the policy schedule for the relevant claim type and policy year. |
| "Each section has its own excess." | That may be correct, but ask why the facts amount to separate claims/sections under the wording. |
| "You are underinsured." | Ask what clear valuation question was asked and how the average reduction was calculated. |
| "The item limit applies." | Check whether the item falls within that category and whether the limit is per item, set or claim. |
Evidence worth keeping
Build the file around the issue the insurer actually has to decide. Preserve documents from the time of the claim rather than relying on memory later.
What to do
A practical next-step plan
- Ask for a gross-to-net settlement breakdown.
- Match every deduction to a policy clause.
- Check the relevant policy year and renewal changes.
- Challenge arithmetic or categorisation errors.
- Escalate unresolved deductions through the insurer complaint process.
What happens after you make a formal complaint?
The insurer or other regulated firm should acknowledge and investigate the complaint under the FCA complaint rules. For most ordinary insurance complaints it should send the required written response within eight weeks. Keep the complaint separate from day-to-day claim chasing: the claim can continue progressing while the complaint tests the decision or handling.
If you receive a final response and remain dissatisfied, check Financial Ombudsman eligibility immediately. FOS normally requires referral within six months of the date on a valid final response. Continuing to argue with the insurer does not safely stop that external clock, so diary it even if the firm says it is willing to look again.
