LONDON (Reuters) - More than two million Britons who are in permanent employment are at the same time trying to turn their favourite hobby into a business, according to a new survey released on Monday.

Commissioned by Direct Line for Business, the poll also found that for 23 percent of Britons it would be a dream come true to start up their own business based on an outside interest.

Of those who have already made the jump to self-employment, 32 percent described it as a successful venture, and more than 25 percent said they were making good money from the business.

The survey listed the most successful hobby-based businesses as fashion design, eBay selling, buy-to-let property development and web design.

"Starting your own business can be both a challenging and an exciting opportunity, but it is not for everyone, as some people just prefer the peace of mind of a guaranteed monthly income," said Kate Syred, head of Direct Line for Business.

"For those willing to put in the dedication to succeed, it can transform your favourite pastime into an income generator and can add an extra dimension of enthusiasm to a day-to-day routine."

The online poll of 2,234 Britons was carried out between July 4 and 8.
