The Chartered Institute of Purchasing and Supply / RBS survey also reported a growth in new business - implying that demand for services will continue to grow in the coming months.
An index measuring business investment also improved, offering hope that an increase in future business activity may be on the cards.
"A number of companies added that investments in new business facilities would underpin higher activity in one year's time," the report said.
Chief economist at RBS Group, Andrew McLaughlin, said the data suggested the UK economy was on course for higher GDP in the second quarter of the year.

The report follows a study released last week showing manufacturing confidence had enjoyed a strong upturn during April, with the index of future business expectations hitting its highest level since November 2004.
