Why the postcode can make a big difference to your rebuild costs
93% of UK properties are insured for the wrong amount, according to research by RebuildCostASSESSMENT.com. The regional breakdown behind this figure shows why location still matters when calculating rebuild values. National figures demonstrate the scale of the issue and regional data helps show where inaccurate sums insured are more common.
“Two similar properties in different postcodes can have very diverse rebuild cost outcomes once local labour, site access, contractor availability and rebuild requirements are taken into account,” according to Sharon Masters, AIIRSM MARLA TechCIOB, the Technical Lead and Surveyor at RebuildCostASSESSMENT.com.
“Local market conditions can make a real difference, especially when national cost pressures meet local planning rules, labour, logistics and contractor availability.”
The availability and cost of skilled trades are one of the main reasons rebuild costs vary regionally. In some regions, limited labour and high contractor demand can increase rebuild costs and extend timescales. In rural or less well-served areas, limited access to specialist contractors can affect pricing, availability and project timelines.
Material availability, transport distance and site access can all influence rebuild costs. Properties in harder-to-reach locations, or those needing specialist materials, can face extra logistical costs. Urban sites can bring different challenges, from restricted access and limited storage space to working-hour limits.
Planning rules, heritage requirements and approvals can affect what needs to happen during a rebuild, particularly for conservation areas, listed buildings or more complex properties. In conservation areas, listed settings or areas with specific planning rules, the rebuild may need to allow for extra permissions, specific materials or professional input. All of this can affect the final rebuild cost.
What can be done?
For property owners and brokers, this is where the data becomes useful. Headline figures show the scale of the issue, but they cannot explain every rebuild-cost risk at the property level. A rebuild cost assessment based on current regional data can give a clearer view of the local conditions affecting rebuild costs than a broad national average.
“Regional cost mapping helps connect the national picture to the reality of each property,” Sharon Masters concludes. “It helps each valuation reflect where the property is, rather than relying only on national trends.”
The key point? The regional differences in insurance accuracy data are not random. For fair-value insurance, the aim is not simply to increase sums insured. It is to check whether the figure reflects the property, its location and the current cost of rebuilding.
