Find out when any UK house was built and its construction type by postcode, using publicly available government EPC data.
Insurers often ask for a property's build year before providing a quote. Use this free property age checker to get an estimated build date and construction type for any address in England and Wales.
Enter the postcode, select the address, and view the build year, construction type and property era under Basic Details.
Enter the postcode into this tool and select the address. The estimated build year or construction era is sourced from publicly available EPC (Energy Performance Certificate) data held by the government. For properties with no EPC on record, the age may not be available.
Insurers use the build year to assess the likely construction methods and materials used. Older properties may have solid walls instead of cavity walls, original wiring, or lead pipes — all of which affect the cost and risk of insuring the property. Knowing the build year helps insurers provide an accurate quote.
If there is no EPC registered for a property, the build year will not be available through this tool. In that case, the seller, local authority building records, or the Land Registry title register may hold this information. Newer builds or properties not yet sold may also lack EPC data.
The age is an estimate based on the EPC record for that property. EPCs record the approximate construction date and are generally accurate to within a decade. If you need an exact build date for legal or insurance purposes, a professional surveyor or the local authority building control department can provide confirmation.
Yes. The construction era can significantly affect value — period properties often command a premium, while homes built in certain eras may require more maintenance. You can check estimated market values using our free property valuation tool.
The construction type describes how the property was built — for example, cavity wall, solid wall, timber frame, or system built. Different construction types have different insulation properties and maintenance requirements. This information is useful for understanding heating costs and planning renovations.
Not necessarily, but some lenders apply additional scrutiny to very old properties or those with unusual construction types such as thatched roofs or timber frames. It is worth checking the construction type alongside the build year, and raising any concerns with a mortgage broker before you make an offer.
Properties built before 1930 are likely to have solid walls rather than cavity walls, which makes them harder to insulate and can lead to higher heating bills. Other things to consider include original or outdated electrical wiring, older plumbing, and the presence of lead paint or asbestos in certain fixtures. A full structural survey is strongly recommended for properties of this age.
Understanding the build era helps you know what questions to ask and what to look for on a viewing. Properties from different periods come with different strengths and weaknesses — from the quality of the brickwork to the likely state of the roof or insulation. Knowing the era in advance means you can focus your attention on the areas most likely to need attention.
