What does rebuild cost mean?

It means how much it would cost to rebuild your home if it were ever badly damaged and needed to be built again from scratch. That includes materials, labour, and everything needed to put it back as it was.

It can vary from home to home depending on things like how it's built, any special features, and whether it's a listed building.

What's the difference between the rebuild cost of my home and the market value?

Market value is what your home would sell for, taking into account things like its location, local demand, school catchments, and the wider property market.

The rebuild cost is different - it's only based on what it would cost to physically rebuild the property, not what it's worth on the market, and is used to set your buildings insurance cover.

As a result, market value is usually higher than rebuild cost.

It’s important to know this when getting home insurance, as insurers ask for the rebuild cost when you make a claim, not the market value.

If you use the market value by mistake, you could end up paying more than you need to for your cover.

What our home insurance expert says:

“Home insurance should be based on the cost of rebuilding your property rather than its market value. Building costs can change over time due to labour and materials, so using an up-to-date rebuild cost helps ensure your cover is accurate and reflects what it would actually take to rebuild your home if it were damaged.”

What does rebuild cost mean?

Essentially, the rebuild cost of a home is the value of rebuilding the property in the event it's damaged beyond repair. The cost will take into account the price of materials and labour required to complete a rebuild.

Various details affect a rebuild cost such as the materials used to build the property, special features, whether it is a listed building and more.

What's the difference between the rebuild cost of my home and the market value?

The rebuild cost is different to the market value of the property. This is because market value also takes into account additional factors such as location, supply and demand in the area, school catchment and more.

Because of this, your home's market value is typically higher than its rebuild cost. It's important to know this when it comes to getting a quote for home insurance etc. You'll be asked to enter a rebuild cost, and if you use the property market value instead, you could end up paying more for your insurance.
