Cornwall is Britain's most expensive place for a holiday

Britain's most expensive holiday destination is Cornwall, closely followed by Dorset and Devon, says a new survey of self-catering holidays.

The best spot in Britain for those wanting to save money is Shropshire (below).

The county, which boasts Shrewsbury and market towns among its tourist attractions, is the most-affordable destination for a one-week holiday rental from June to August 2014, a TripAdvisor survey shows.

Including two-bedroom holiday rental accommodation, one dining-out meal and basic groceries, a Shropshire self-catering trip cost £566.

The next best-value destination was Dumfries and Galloway in Scotland (£568) followed by Lincolnshire (£569), Derbyshire (£570) and North Yorkshire (£627).

The most expensive destinations in the survey were Cornwall (£854), Dorset (£834) and Devon (£826).

Taking just the accommodation into account, Dumfries and Galloway is the least expensive destination, at £450. In contrast, the accommodation part of a self-catering week in Cornwall would set a family back £745.

TripAdvisor said that the north of England and Scotland largely dominated the the most-affordable destination list, with the three most-expensive locations being in south west England.

"Self-catering holidays are a great way to keep costs down without compromising on quality," said TripAdvisor spokesman James Kay.
