What does contents insurance cover?

Contents insurance protects the personal belongings you keep in your home against risks such as theft, fire, flooding and vandalism. Typical items include furniture, electronics, clothing, jewellery and carpets, and cover often extends to items kept in garages, sheds and attics.

How much contents cover do I need?

The amount of cover you need for contents insurance is determined by the total replacement cost of your possessions. In other words, your cover should match the total value of your belongings and the amount needed to repair or replace them if they were damaged, stolen or destroyed and you had to make a claim.

If you're taking out contents insurance, you’ll need to list everything you would take with you if you moved house.

Tip: smaller possessions often go unnoticed, yet their combined value can significantly impact the total sum insured for contents, so make sure you're thorough!

How to calculate the value of your home’s contents in 4 steps

1. Take inventory

The best way to build your inventory is to work through your home room by room and note down all the items you would want replaced if it were damaged or lost.

Note: permanent fixtures like fitted kitchens count as part of the building, so they should not be included in your contents valuation.

2. Calculate the replacement cost of each item

After completing your inventory, the next step involves working out the current replacement cost of each item. The total value of all your belongings gives you the total sum insured. The replacement cost is the amount it would cost to buy new items today, rather than the original price paid. If receipts are missing or you cannot remember what you originally paid for an item, you can easily check its value online.

Even when the exact product is no longer available, checking the price of a similar item gives you a reliable estimate. This is useful for belongings that have become more valuable since you first bought them.

Note: most insurers will apply a "single item limit" (the maximum amount they will pay for a single item of your belongings) which might be lower than the value of certain belongings in your home. Checking this limit with your insurer helps make sure your cover matches what you actually need before you finalise your inventory.

3. Include high value possessions

Valuable possessions (i.e. over €1,000) such as art, jewellery or family heirlooms may also need a professional valuation. Gold items deserve particular attention because their market value changes frequently, so regular revaluation helps keep your policy accurate.

High value items usually need to be specified and listed individually on your policy. Some insurers may request proof of their valuation before offering cover.

4. Revalue your contents at renewal

When your policy comes up for renewal, make sure you revalue any items that may have appreciated, such as jewellery, artwork, or antiques.

Tip: the easiest way to calculate the value of your contents is by using a home contents calculator, which you will find on many insurance websites.

Room‑by‑room contents checklist

To help you calculate the value of your contents, here's a room-by-room checklist of common items covered by contents insurance so you don't miss anything:

What happens if you underestimate the value of your home contents?

Underestimating the value of your home contents could leave you underinsured. This means your insurer may not cover the full cost of replacing your belongings if you make a claim.

You would only receive a proportion of the amount needed, leaving you to pay the rest yourself. That's why it's important to accurately calculate the value of your possessions so that your cover reflects the real cost of replacing them after an unexpected loss.
