Understanding Policy Limits, Sub-Limits and Aggregate Caps
Insurance limits set the maximum your insurer will pay — but a single policy can contain several different types of limit working together. This guide explains per-occurrence limits, aggregate limits, sub-limits, and how gaps in coverage appear.
The four types of limit
How limits interact in a claim
Multiple limits can apply to the same claim, with each one potentially reducing the payout. The order of application is typically: sub-limit first, then per-occurrence limit, then aggregate.
Overall contents limit: £40,000
Single article sub-limit: £1,500
Camera equipment lost in burglary (replacement value): £3,200
Claim paid: £1,500 (sub-limit applies; overall limit is not reached)
Gap you bear: £1,700
The fix for this particular gap is to schedule high-value items individually on the policy. A scheduled item is listed by name, description, and agreed value — and is paid at that agreed value rather than the sub-limit. This typically adds a small amount to the premium.
Where to find limits in your policy
Limits appear in two places in a standard policy document:
- The declarations page (schedule) — the one-page summary at the front of the policy showing your overall sum insured and premium. This is where headline limits appear.
- The insuring agreement and conditions — where sub-limits and per-category limits are typically buried in the body of the policy. These require a careful read to find.
For a full guide to where each type of information sits in a policy document, see the five parts of every policy. The limit glossary entry covers the key terminology used in policy documents.
Checking whether your limits are adequate
The test for adequacy is whether the limit covers your realistic worst-case loss for each category that matters to you — not just the total. Work through each sub-limit against the value of items you own in that category:
- Single-article sub-limit vs the value of your most expensive item (jewellery, camera, bicycle, watch)
- Liability limit vs the potential size of a claim from your specific activity or property
- Business interruption limit vs your actual monthly revenue and fixed costs
- Medical limit in travel insurance vs the cost of emergency repatriation from your destination
Use the policy comparison tool to place two policies side by side and see where the limits diverge. For the relationship between limits and under-insurance in home cover specifically, see our news article on home rebuild costs and the average clause.
Policy limits FAQ
Frequently asked questions
- You bear the cost above the limit yourself. This is called being 'exposed above the limit'. For large losses — major liability claims, catastrophic property damage — the gap between a policy limit and the actual loss can be very significant. If you have liability exposure above your standard policy limit, an umbrella or excess liability policy can extend cover above it. See our liability and umbrella insurance overview.
- Most contents policies include a sub-limit for 'valuables' or 'single articles' — typically £1,000–£2,500 per item — regardless of the overall policy limit. An item worth £5,000 is only paid up to the sub-limit unless it was specifically scheduled (named and valued) on the policy. Always check sub-limits for high-value items and schedule them individually if needed.
- A per-occurrence limit caps what the insurer pays for any single incident. An aggregate limit caps the total paid across all claims within the policy period (usually one year). Once the aggregate is exhausted, no further claims are paid — even if individual claims are within the per-occurrence limit. This distinction is particularly important in liability and professional indemnity policies.
- Sub-limits appear in the policy schedule (the declarations page) and in the insuring agreement. They may be listed separately under a 'schedule of benefits' or 'summary of cover'. Reading the five parts of every policy shows exactly where to look for limits in a standard policy document.
