Properties on Harpenden’s pricey Park Avenue North have an average value of £3.7 million while the typical cost of a home on Astons Road, Northwood, is £3.5 million.

Surrey trumps Herts in the posh stakes, however – 10 of the top 20 are there, including the most expensive street outside London, Brooks Close in Weybridge, where the average home costs £7.5 million.

Not surprisingly, the least expensive streets are all up north. Davison Terrace in Sunderland is the most affordable of the lot, with an average property value of just £15,000.

The most expensive street of all is, naturally, in London. Anyone looking to purchase property on Grafton Street, Mayfair would need a whopping £69,189,235.
