Why checking your home insurance rebuild cost matters

When arranging buildings insurance, one of the most important figures homeowners should pay attention to is the reinstatement cost.

This figure indicates the amount required to completely rebuild your home if it were severely damaged or destroyed. Making sure its accuracy is essential, as it can have a significant financial impact if you ever need to make a claim.

 

What is the reinstatement cost?

The reinstatement cost is the estimated cost of rebuilding your property from the ground up. It generally includes:

• Labour and construction materials


• Site clearance and debris removal


• Professional fees, such as architects, engineers, and surveyors

Importantly, the reinstatement cost reflects the physical expense of rebuilding the structure. It does not include the value of the land or the price someone might pay to buy the property on the open market. This can lead to confusion. A property with a market value of £750,000 might cost significantly less — or sometimes more — to rebuild, depending on its size, design, and construction methods. Because of this difference, it is crucial to ensure that the rebuild cost listed on your policy is accurate.

 

The risks of getting it wrong

If the reinstatement cost on a policy is too low, the property might be underinsured. During a claim, insurers may apply what’s known as the Average Clause, which can reduce the payout proportionally to the shortfall in cover. In some cases, a claim could even be denied. This could leave a homeowner responsible for covering a significant part of the rebuilding costs themselves.

On the other hand, setting the reinstatement cost too high can also have disadvantages. Overestimating the figure might lead to paying higher insurance premiums than necessary each year.

 

Why the reinstatement figure should be reviewed regularly

Rebuild costs can change over time. Factors such as inflation, labour shortages, supply chain pressures, and changes in building regulations can all raise the cost of materials and labour. Economic and political events (for example, Brexit, which affected material supply and pricing) have also impacted building costs in recent years.

Because of this, it’s advisable to regularly review the reinstatement cost on your policy. This is especially important if you’ve made improvements to your home, such as:

• Adding an extension


• Converting a loft


• Renovating or installing a new kitchen

Changes like these can significantly increase the cost of restoring the property.

 

Mortgage lenders often require it

Most UK mortgage lenders require buildings insurance that reflects the reinstatement cost, not the property’s market value. This ensures the lender’s financial interest in the property is properly protected. If the insured sum is too low, homeowners may accidentally breach their mortgage conditions.

 

How to check your rebuild cost

There are several ways to estimate a property's rebuild cost. A common initial tool is the BCIS Rebuild Cost Calculator, produced in partnership with the Association of British Insurers. For more complex properties — such as listed buildings or homes with unusual construction — it is often best to obtain a professional assessment from a chartered surveyor.
