However, to ensure winners' privacy and safeguard their personal details, NS&I adheres to strict rules when it comes to disclosing prize-winning locations, reports . "Each customer is assigned to a town, local authority, county or Government Standard Region and country.

"When a winner is assigned to a town with less than 100,000 holders assigned to it, then we use the following hierarchy until we find a level where that area has at least 100,000 Premium Bonds holders," the rules explain. "For large towns and cities that are divided into local authorities or boroughs, we quote the area with the fewest customers over the 100,000 reporting limit. This may mean the list quotes a local authority area or borough instead of the town or city.

"For Premium Bonds holders living outside the UK, we only publish the country when there are at least 100,000 holders living there. Otherwise, we publish the area as 'overseas'."
