Underinsurance means your contents are worth more than the sum your policy covers — so if disaster strikes, your payout falls short. The good news: you can estimate your own coverage gap in an afternoon, room by room.
What “underinsurance” and the coverage gap actually mean
Your contents sum insured is the maximum your policy will pay to replace everything you own. Underinsurance happens when the real value of your possessions exceeds that figure. The coverage gap is the difference between what your contents are genuinely worth and the sum insured — but a realistic gap isn’t a naive subtraction. It also accounts for your deductible and whether the policy settles claims at replacement value or resale value.
Why most households are underinsured without knowing it
Few people ever set their sum insured deliberately. It’s usually a rough guess made when the policy was opened — and then never revisited. Meanwhile you keep accumulating things: a new sofa, a laptop upgrade, kitchen appliances, a bike, years of clothing and electronics. Nobody re-tallies all of it. The result is a slow, invisible drift where your possessions grow but your coverage stays frozen at an old estimate.
How to estimate your real contents value, room by room
The most reliable way to find your true number is to inventory what you own one room at a time, rather than guessing a lump sum. Walk through each space and note the meaningful items:
- Living room — TV, sofa, audio gear, furniture
- Kitchen — appliances, cookware, small electricals
- Bedrooms — wardrobes of clothing, beds, devices
- Office — laptops, monitors, tools, equipment
- Storage, garage and outdoors — bikes, sports kit, tools
For each item, estimate its replacement value — what it would cost to buy new today — since most contents policies insure to replacement value. Apps like Vavaro build this room-by-room inventory for you and estimate each item’s replacement value, then total it so you have a grounded figure instead of a guess.
How your deductible and the valuation basis change the gap
Two policy details quietly reshape the gap. Your deductible is the amount you pay out of pocket on every claim, so it’s effectively part of the shortfall you carry. And the valuation basis matters: a policy that pays replacement value (new-for-old) leaves a smaller gap than one paying resale value, which depreciates older items. A realistic coverage gap factors both in — which is why a simple “value minus sum insured” can mislead in either direction.
High-value items often need to be listed separately
Standard contents cover usually caps how much it pays for any single valuable. Jewellery, watches, art, cameras, musical instruments and collectibles can exceed those per-item limits, meaning they’re only partly covered even if your overall sum insured looks adequate. Identify these items and check whether your insurer wants them scheduled or listed individually. Vavaro flags high-value items that may need separate cover, so they don’t slip through.
A simple step-by-step to check your own gap
Pull it together in five steps:
- 1. Inventory each room and note replacement value per item.
- 2. Add it up for your true total contents value.
- 3. Find your current sum insured on your policy schedule.
- 4. Note your deductible and whether claims pay replacement or resale value.
- 5. Compare the realistic value against the sum insured — that difference is your coverage gap, and a flag to review your policy.
