In the world of insurance, the sum insured is much more than just a figure on your policy: it is the maximum limit you will receive in the event of a claim and the basis on which your premium is calculated. But what happens if that sum does not reflect the real value of your assets after a period of inflation? This question is crucial for individuals, the self-employed, SMEs, and those with significant assets who wish to safeguard their financial peace of mind.
What is the Sum Insured and Why is it So Important?
The sum insured is the maximum amount the insurer will pay out if a claim occurs. In home insurance, for example, it is divided into two main categories:
- Buildings Sum Insured: This corresponds to the cost of rebuilding the property, including materials, labour, demolition costs, permits, and professional fees.
- Contents Sum Insured: This is the replacement value as new of all items within the property: furniture, appliances, clothing, personal belongings, and especially valuables and jewellery. For these items, it is essential to keep invoices and ensure they are listed in the policy with their declared value per item.
How To Calculate The Correct Sum Insured
Calculating the correct sum insured is essential to avoid unpleasant surprises. It is not just a matter of estimating an approximate value, but of carrying out a detailed and up-to-date inventory of your possessions. Ask yourself:
- How much would it cost to rebuild my home today?
- What is the replacement value of my possessions?
- Have I recently acquired new items or carried out renovations?
At Op de Beeck & Worth, we recommend reviewing and updating your sum insured at least once a year, especially after periods of high inflation or significant changes to your assets.

The Problem Of Under Insurance And The Average Clause
If the sum insured is lower than the real value of your assets, you are exposed to under insurance. In the event of a claim, the insurer will apply the average clause: you will only receive a part of the settlement, in proportion to the sum insured compared to the real value. For example, if you insure your home for £200,000 but its real value is £300,000, you will only receive two-thirds of the compensation.
This mistake can have serious financial consequences, forcing you to cover a significant part of the damages yourself. For businesses and the self-employed, the impact can threaten business continuity.
The Impact Of Inflation On The Sum Insured
Inflation directly affects the cost of rebuilding and replacing assets. Although many policies include automatic indexation clauses, the recent period of inflation has often outpaced these adjustments. Furthermore, we live in a dynamic and consumer-driven society: new acquisitions, renovations, and business expansions increase the value of insured assets, which is not always reflected in the policy.
For this reason, it is essential to regularly review the sum insured and adjust it to reflect the current reality. Only then can you avoid under insurance and guarantee the protection of your assets.
Difference Between Sum Insured, Premium, And Excess
Understanding these differences will help you choose the policy that best suits your needs and avoid confusion in the event of a claim.
- Sum Insured: Maximum settlement limit.
- Premium: The cost you pay for your insurance.
- Excess: The amount you are responsible for before the insurer covers the rest of the claim.

Tips For Maintaining The Correct Sum Insured
- Keep an up-to-date inventory of your possessions, including invoices, photographs, and detailed descriptions.
- Update the inventory with every new acquisition, renovation, or relevant change.
- Pay special attention to valuables and jewellery, listing them in the policy with their declared value.
- Seek expert advice to calculate the true replacement value of your assets.
- Review your policy at least once a year, especially after periods of inflation.
