Figures from Nationwide suggest there is an 18% premium for a property situated within a National Park and an 8% premium for a property within 5km of a National Park.

"Around 190,000 households in Great Britain are located within the boundaries of National Parks," said Robert Gardner, Nationwide's Chief Economist. "National Parks are highly desirable areas to live thanks to the beautiful countryside. Development is also strictly controlled, with very little in the way of new housing construction, which also helps to explain why prices are relatively high.

"The Peak District serves the highest number of people, with around 5.9 million living within 25km of its boundary. Its central location makes it accessible from major population centres such as Derby, Sheffield and Manchester."

England’s newest National Park, The South Downs National Park in  Hampshire and Sussex,contains the highest number of households, around 47,000. The park includes a number of towns including Petersfield, Liss, Midhurst and Petworth.
