Remortgage demand jumps
10 July 2026What is the rebuild cost divide?
Many UK homeowners could be underinsured because rebuild costs are often very different from property values, particularly in certain parts of the country.
Property value versus rebuild cost
House prices are not simply based on the cost of rebuilding a home. In many areas, values are heavily influenced by location and land prices rather than the bricks and mortar alone.
As a result, the rebuild cost of a property can differ significantly from its market value. In some regions, the cost of reconstructing a home after a major disaster could exceed the insured amount by hundreds of thousands of pounds.
Research suggests regional variations are becoming increasingly noticeable. In some parts of the UK, particularly where property prices have risen sharply due to demand and location, the market value of homes can be substantially higher than the actual rebuild cost. In other areas, rebuild costs can outweigh property values due to rising construction expenses and local labour shortages.
This means homeowners cannot assume their property’s sale price automatically reflects the amount they should insure it for.
The underinsurance problem
Buildings insurance limits are often linked to property valuations, which can create serious underinsurance risks. If cover is based on an inaccurate estimate, homeowners may find they are not fully protected if they ever need to make a major claim.
Recent analysis found that 70% of UK properties are underinsured, while 23% are overinsured, leaving only a small minority insured for the correct amount. The regional divide is also significant. Wales recorded the highest level of underinsurance at 80%, followed by the North West at 77% and Northern Ireland at 75%. Meanwhile, Scotland and the South East reported some of the highest levels of overinsurance.
Construction costs, labour shortages and rising material prices have further increased the importance of accurate rebuild assessments in recent years. The cost of materials has fluctuated considerably, while higher energy and transportation costs have also affected the sector.
How homeowners can review cover
Many homeowners mistakenly assume their insurer will automatically calculate the correct rebuild value. However, this is not always the case, which is why reviewing your cover regularly is so important.
Home improvements, such as extensions, can also affect rebuild costs. If these changes are not reflected in your insurance policy, you may not have sufficient cover in place.
Having the right level of buildings insurance could help prevent costly shortfalls following major property damage.
