The average price of a property within the boundaries of a national park is £422,225, compared with the £279,171 county average.

There were also price differences between protected green areas, with Chichester Harbour holding the highest house premium compared with other counties, at 122.1%, while Howardian Hills came in at the bottom of the list, with 89.3% premium above county average.

Frances McDonald, director of research at Savills, said: “Over the last few years, as buyers have re-evaluated their priorities, we have seen a surge in interest in living amongst greenery or nearby access to green space.

“Our analysis reveals that the highest premiums can be found in the National Landscape of Chichester Harbour."
