When you purchased the property a homebuyer’s survey is likely to have included the date of construction. 

Alternatively, your local authority may have a record of when planning permission was granted to build the property. Your neighbours may also have an idea of when the property was built.

Note: A rough estimate of the property construction date is enough for the purposes of getting your home insurance quote.

If you have a heritage property, here are some steps to take:

• Search for your property for free in the 1862 Act register on Land Registry’s digital archives.
• Look at the architectural style and features of the house, particularly the roof and windows.
• Check your county record offices, local parish records or ask to view local archives at your library.
• Look for old copies of Ordnance Survey maps for your area (local library).
• Google for a local historian or a historical society and contact them to see if they can help you.
• Look at census data between 1841 and 1911 to find the first year that the address was mentioned.
