Who are the biggest Accounting firms … after the big 4?

Often when you think about accountancy, more than likely you are instantly drawn to the novelty and reputation of the Big 4. KPMG, EY, PwC and Delloite are global powerhouses and have earned the reputation they hold not only in the UK, but globally. With head offices in London, as well as sites all across the UK, the Big 4 hold mass appeal. But what about other firms that don’t make it into the exclusive boys club? We look at the top firms in the UK outside of the big 4, with headquarters in the capital city.
