How much home insurance cover do you need?

Here at moneysupermarket.com our aim is to save you money on your house insurance. That's why we have produced a guide to help you calculate the level of home insurance cover you need.

Contents Value Chart

It is important to value all the contents in your property. Be careful not to under insure or you could miss out when the time comes to make a claim. However, at the same time, don't over insure, as this will simply increase the cost of your premium unnecessarily.

To measure the value of the contents go around every room in your house and assess their cost. This should cover all the contents that are not covered by building insurance and should include items that have been bought for you or that have been made, as these too will have to be replaced. Add a percentage for inflation and then total the contents - this should be the minimum you insure for.

Simply guessing the right amount without totalling the contents will usually backfire and leave you under insured by as much as 20%.

Rebuilding Cost Information

This is an area that can often be open for debate between the insurer and the consumer. That's why it is the responsibility of the insurer to get this figure right.

Remember to insure the rebuilding cost of your home rather than the market value. Land normally accounts for about a third of the property's value, yet it is not under threat from theft, storms or fire. Consequently, covering the rebuilding costs of your home rather than the market value saves on your premium. It is often less costly to rebuild your damaged house than buy another as the land it sits on typically remains unscathed.

The Building Cost Information Service (BCIS) is widely used by surveyors to provide cost advice and calculate insurance reinstatement cost investments. They are commissioned by the Association of British Insurers (ABI) to provide guidance for the rebuilding costs of properties.

To assist you in assessing the rebuilding costs of your home, moneysupermarket.com has produced a guide to help you make good judgements to form an accurate calculation of the home insurance cover you need.

Please note that this guide is no substitute for professional advice, which can be obtained from a chartered surveyor. It is a general guide that does not take into account specifics such as properties not built out of brick, properties with basements/cellars, houses with special design features, houses other than those of average quality. However, we hope you can use it as a general guide to assist you in getting the best home insurance deal for you.
