Solicitors lack information on how they compare with their rivals, in the view of business advisers Grant Thornton. Accordingly, the firm is to undertake a survey on the issue. The 'inter- firm comparison' intends to compare firms in the same region with others of similar size. Participation will cost pounds 300 per firm. Those interested should contact Michael Rogerson on 071-728 2342 or Andrew Otterburn on 0532 455514. The results of the survey will be available in the autumn.
