These are the 9 consultancy firms where British employees earn the most

PwC, the largest of the Big Four professional services firms, pays its consultants substantially more than it pays employees in its core business, accountancy. However, PwC doesn't rank particularly highly when it comes to either salary or bonus satisfaction.

Consultant salary: £33,850

Senior consultant salary: £49,000

Bonus satisfaction: 17%

KPMG may be the smallest of the Big Four professional services firms, but it pays consultants more than both PwC, and EY (which doesn't even make this list). It pays its junior consultants a huge £6 ($8.56) more than rival Deloitte.

Consultant salary: £34,006

Senior consultant salary: £53,450

Bonus satisfaction: 32%

Junior consultants at Deloitte may take a £6 hit on pay compared to those at KPMG, but senior employees in Deloitte's consultancy arm earn roughly £2,000 ($2,850) more than their counterparts at KPMG. Deloitte's consultants aren't particularly happy with their bonuses though, ranking third from bottom of this list.

Consultant salary: £34,000

Senior consultant salary: £55,400

Capco, which focuses its consulting with the financial services sector, is in the middle ground, paying consultants far more than the Big Four accountancy firms, but far less than top tier, specialist consultancies. Its employees are the least satisfied with their bonuses of any UK-based consultants.

Consultant salary: £40,000

Senior consultant salary: £78,450

Bonus satisfaction: 14%

McKinsey is probably the best known name in the consultancy business, and that fame translates into big salaries for staff. Senior staff are the fourth best paid of any consultants in the UK, and junior consultants make the third most money. That, coupled with 50% bonus satisfaction, makes McKinsey a pretty lucrative place to work.

Bonus satisfaction: 50%

Bain, which employs around 5,700 people across the world, pays its senior staff in the UK more than any other firm on this list, with an average salary of almost £100,000. Junior staff rank just fourth overall for pay, but earn just £1,000 less than senior staff at Accenture.

Consultant salary: £46,000

Senior consultant salary: £98,000

Bonus satisfaction: 50%
