Employees were made aware of the proposed sale via an email announcing that project director, Andy Thornton, had been appointed to prepare the way.
The news will not come as a huge surprise as the intention to make the business commercial has been on the cards for two years.
BBC Resources deals with outside broadcasts, studios, post-production and costumes. The corporation has said it will not sell off the costume department.
A BBC spokeperson said: 'We have appointed a project director to look at all the sales options. No sales process has been started and there's no confirmation of a sales process in whole or in part.'
The BBC has wanted to sell BBC Resources two years ago, but plans were put on hold in the face of strike action.
In a deal brokered with broadcasting union Bectu in June 2995, BBC management said no move to sell the division off would be made before January 2007 and that a deal would not be completed until July.
The commercial division has a turnover of £130m, with 80% of its business coming from the BBC. It employs around 1,300 staff.
Most of the staff are now expected to follow former colleagues into transmission, technology, playout, media planning, payments and human resources.
The biggest worry for the staff are job security and pensions, with the feeling that the company may be split up between outside broadcasters, studios and editing, with the fear that the smaller companies buying up these divisions will not match the pension levels the workers have under the BBC scheme.
The BBC has previously sold off other commercial subsidiaries such as BBC Broadcast and BBC Technology.
