The farmhouse featured in the 1987 comedy, which starred Richard E Grant and Paul McGann as down-on-their-luck actors. The pair escape their squalid London flat for a weekend in the country at Withnail’s "Uncle Monty’s cottage".
Sleddale Hall has been vacant for many years and is accessible only via a dirt track. It is almost two miles from the nearest public road and a mile from the nearest inhabited house.
Edward Holt, United Utilities senior land agent on its Thirlmere Estate, said: "Sleddale Hall is in one of the quietest parts of the Lake District. I hope it is bought by someone who can restore it. It would make a lovely family home."
Savills director Paul Mooney said: "Withnail is an iconic film and there may be a few eccentrics out there who would be interested in owning a piece of film history. Sleddale Hall will certainly garner a bit more public interest than a house of this type normally would."
Sleddale Hall goes under the hammer at the Berkeley Hotel in Knightsbridge, London, on February 16.
