Calculate home insurance costs
How to calculate the cover you need from your home insurance policy before comparing quotes with MoneySuperMarket
Looking for home insurance?
How much does house insurance cost?
The cost of combined home insurance fluctuates across the country, averaging at £1456 per year*. The amount you pay depends on factors such as:
Where you live
The size of your home
Whether you live in a house or a flat
How much your belongings are worth
To get the best deal, you will therefore need an accurate idea of the value of your home and its contents. Overestimate this figure, and you’ll pay more than you need for home insurance. Underestimate it, and you won’t have the necessary protection should something go wrong.

Calculating the cost of home insurance
Home insurance covers two main areas:
Buildings insurance is designed to pay out for structural damage to your home, including the cost of rebuilding it if necessary
Contents insurance is designed to protect the belongings you keep in your home, from electronic items such as your television to carpets and clothes
The two types of cover can be bought separately or as part of a combined home insurance policy. Either way, insurers calculate the cost based on factors such as the location and size of the property and/or the value of your belongings.
Buildings home insurance cover
Factors that affect the cost of buildings insurance include:
Where you live
The floorspace of your property
The property age and type
But the most important factor for insurers is the rebuild value, or the amount it would cost to completely rebuild your home if it were destroyed beyond repair.
This will depend on its structure, as well as its size, and is often considerably lower than the market value. However, it still needs to be enough to cover the cost of all the labour and materials required. That’s why you should let your insurer know if you make changes likely to increase the rebuild value, such as building an extension.
Home contents insurance cover
As a rule of thumb, anything you could physically remove from your home will be covered by your home contents policy, including:
Carpets and curtains
Should I get separate policies for home insurance?
Not everyone needs both buildings and contents cover. If, for example, you own a flat, buildings cover may be included in your annual management charges.
However, if you do need both contents and buildings insurance, it’s worth shopping around for a combined policy before comparing this with the cost and cover provided by separate policies.
Many insurers offer discounts when you buy home contents insurance and buildings insurance cover as a package. But if you have a large home or lots of valuables, two policies may prove a better option.
Do I need to know what my home and contents are worth?
Yes, it’s important to have a good idea of both the value of your home contents and how much it would cost to rebuild your home.
If these figures are too high, you will pay more than you need for your home insurance. If they are too low, you could be left out of pocket if you need to make a claim.
