Part-time higher education students are to get more help with paying fees from next September, the government says.
Universities decide fees for part-time students
For the first time, cash will be linked to the "intensity" of study, so those studying 75% of the time will get more than those doing 50%.
This will take the maximum amount available from £575 to £840 a year.
Fees for part-time students are set by universities themselves, with eight out of 10 charged between £400 and £1000 a year.
This funding changes will apply to new and existing undergraduates.
The income threshold below which a single student can qualify for full support is also being raised from £14,600 to £14,970.
Students will continue to be able to apply for a grant of £250 a year towards their course costs.
Meanwhile, a survey of 3,294 part-time undergraduates by the Open University shows average extra costs - such as books and travel - are £246 a year.
The survey also found 83% of part-time students were in paid employment with 65% in full-time work.
Some 41% of part-time students received help with their fees from an employer.
Higher education minister Kim Howells said: "This demonstrates the commitment of UK business to improving the skills of their employees and I hope to see the percentage of employers supporting their staff increase further in future years."
The Open University survey involved 3,294 part-time students.
