Boasting an average price tag of £15.6 million for a home, Ilchester Place in the heart of Holland Park, London, has been identified as the most expensive residential street in England and Wales.

Lloyds Bank, which compiled the research using Land Registry data, said every region of England has at least one "million pound street" - where the average home is valued at £1 million-plus.

In total, 76 million pound streets were found - including one in Wales.

Llys Helyg Drive in Llandudno, with its stunning sea views, has an average house price of £1,121,000, Lloyds found.

Of the top 20 most expensive streets, 10 are in London - and seven are in the borough of Kensington and Chelsea.

Andrew Mason, mortgage director at Lloyds Bank, said the prime London boroughs of Westminster and Kensington and Chelsea continue to top the tables.

He said: "Seven addresses in these two areas alone come with an average price tag of more than £11 million and three cost more than £13 million.

"Although half of the 20 most expensive streets are in London, regions across England and Wales now all have at least one million pound street.

"In total, there are 76 of these prestigious addresses across the country."

While London and the south-east dominate the list of the most expensive streets, the research also found:
