Accountancy firm Ernst & Young (EY) has seen annual revenue grow eight per cent to £2.01 billion after seeing all its business units expand.

It said distributable profits were up six per cent from £412 million to £437m in the 12 months to July 3.

Average profit per partner was down 3.7 per cent from £727,000 to £700,000 in a year when 96 new equity partners were added.

In Scotland, where the firm employs 990 across offices in Aberdeen, Edinburgh, Glasgow and Inverness, it added 13 new partners to take the total to 34.

Mark Harvey, partner and market leader for Scotland, said: “It has been yet another year of significant growth for EY in Scotland.”

Mr Harvey said the firm is on course to grow to around £200m revenue in Scotland by 2020.

He said: “I am feeling very positive about the health of the Scottish economy. Improved market conditions have provided us with a great platform to further accelerate our investment in the business. We are seeing an increased demand from our clients for our services to help them drive growth and trade in both the UK and internationally.”

Across the UK the firm saw its assurance practice grow 6.4 per cent to £585m winning audit clients such as The Co-operative Bank, BBC, London Stock Exchange, Sainsbury’s Plc and Sage.

It has picked up mandates from the likes of Royal Bank of Scotland, Royal Dutch Shell and Associated British Foods.

EY’s advisory arm grew revenue 4.5 per cent to £584m while transaction advisory service was up 12.1 per cent to £324m.

The tax practice increased by 10 per cent to £517m.

The financial services sector remains the biggest user of EY’s services.

Steve Varley, EY’s UK chairman, said: “We had several fantastic audit wins in FY15, which not only reflect our continued investment in improving quality but also the significant investment we have made into digital analytics and real-time assurance. We continue to invest in the same areas as last year - fraud investigation technology, corporate integrity and cyber security.”
