More than 5,000 unclaimed estates remain across the UK, with a total estimated value of nearly £1.5 billion, according to new data from the unclaimed estates list as of February 2026. The average property price of £270,259, applied to 5,472 properties, underpins the staggering sum.
Law firm Weightmans has analysed the surnames and regions most associated with these estates. Smith leads the surname list with 94 instances, followed by Jones, Brown, Williams and Taylor. London accounts for the highest number of unclaimed estates in England, with 1,612 properties still awaiting heirs, while Surrey follows with 283 and the West Midlands with 253.
Richard Bate at Weightmans said: "Creating a will is more than just a legal necessity; it's a critical component of financial wellness. Without a clear will, you're leaving the fate of your assets up to the courts, which can lead to long, stressful disputes among your potential heirs."
The data reveals a regional imbalance, with more than half of the top 20 areas located in the south of the country. The oldest estate on the list dates back to 1974, highlighting how long some estates can remain unsettled.
Weightmans emphasised that a professionally prepared will allows individuals to specify beneficiaries, who need not be family members but can include friends, charities, or organisations. By documenting final wishes clearly, people can prevent their estates from becoming unclaimed and defaulting to state ownership.
