It may be four years since legislation allowing accounting firms to become limited liability partnerships was passed, but most are choosing to stick with the traditional partnership model.

The 2005 Accountancy Age Top 50 shows that only 20 of the UK’s leading 50 firms have adopted an LLP structure, despite the protection it offers. The survey showed that while the Big Four and larger mid-tier firms were LLPs, smaller firms have chosen to maintain the partnership structure.

John Davies, head of business law at ACCA, said this was not surprising, given the differences in scale between the top 10 firms and smaller partnerships in the UK.

‘The ethos of partnership is that its members can trust each other, are liable for each others’ debts and have a substantial level of expertise in all facets of the business,’ Davies said.

‘The giant firms have a kaleidoscope of technical areas and 150 to 200 partners. There is serious pressure on this ethos and an LLP is more appropriate.’

Davies said smaller firms with only 10 to 20 partners could still efficiently maintain the traditional partnership structure and that it was ‘quite understandable’ that they had done so.

‘When the Big Four changed to LLP they would have done a cost-benefit analysis and calculated that the benefits outweighed the drawbacks of having to produce publicly-reported accounts,’ Davies said.

‘For small firms that don’t have the same size and exposure, it is not always as beneficial.’
