Research conducted by Lloyds Bank found that in England and Wales houses in national parks cost £118,711 more on average than other houses in the same locality.

The average price of national park housing is also 11.6 times higher than the local average gross annual earnings.

Properties in the New Forest in the south of England were the least affordable, with the average price of £577,979 some 15 times the local average gross annual earnings.

This was follow by properties in the South Downs (13.6) and the Peak District (10.8).

Andrew Mason, mortgage products director at Lloyds Bank, said: "Quality of life and an attractive environment are two major factors for people eyeing their next home move, and our national parks provide both of these in abundance.

“It’s therefore not surprising to learn that many home movers are prepared to pay a premium to live in some of the most beautiful parts of the country.

“These highly attractive areas are also very popular with second home purchasers.

“However, as some of the homes in these areas can cost as much as 15 times the local average wage, there is a risk that some people living and working in these areas could be priced out of the market.”
