Managing partner at Brabners Michael Brabner said: "Real estate and corporate have both been extremely successful for us this year. I'd be very surprised if other firms in the North West hadn't experienced the same growth in these areas."
Brabner also highlighted the acquisition of the firm's new sports practice, which it acquired from James Chapman in March last year, as a contributing factor in its increased turnover.
Hill Dickinson's turnover is up by 31 per cent for 2006-07, reaching £68.4m, while Cobbetts announced an 8 per cent increase, with turnover up to £58.5m.
Cobbetts, which is preparing for its first office in London, said the success of mergers with Leeds-based firm Wilbraham & Co and Birmingham's Walker Charlesworth & Foster in 2004 has come to fruition this year.
Cobbetts managing partner Michael Shaw said: "The growth we've experienced for 2006-07 is in line with our growth strategy.
"We're very much looking forward to our new corporate practice in London, which will be a great asset."
