British companies are quietly ditching their accountants for outside help — and cash, surprisingly, has almost nothing to do with it, a new study reveals.
More than a third of U.K. businesses that use common accounting advisory services are getting that work done by someone other than their main accounting firm even when their own firm already offers the exact same service, according to research released July 15, 2026.
The research, based on a survey of 500 U.K. businesses, was commissioned by Ravical, a London and Belgium-based firm that sells AI software to accountants, and carried out by polling company Censuswide in May.
Researchers found the trend held across the board — from cash flow planning and tax strategy to growth support and pricing analysis — with clients scattering their business across multiple providers instead of sticking with one trusted firm.
Cash flow planning and forecasting turned out to be the service businesses were most likely to keep in-house, with 52% getting it from their primary accounting firm. Still, more than a third of clients went elsewhere for it anyway. Performance reviews, tax planning, growth support and pricing analysis all showed similar splits, with 38% of clients typically hiring a different provider for those services.
Small firms hit hardest, Top 50 firms holding steady
The size of the accounting firm made a big difference in how much business was walking out the door.
Sole practitioners saw 42% of their clients using another provider for services they could have handled themselves. Small firms with just two to ten staffers fared worse, with 48% of their clients turning elsewhere — the highest leakage rate in the survey — while those clients were also the least willing to pay more, offering just a 9% increase on top of an already-modest average annual spend of £12,559 ($16,803).
Firms with 11 to 250 employees landed in the middle, with around 40% of advisory work sourced elsewhere. But researchers noted these clients spent more overall and showed a greater appetite for paying extra — meaning mid-sized firms are sitting on a pile of revenue they aren’t collecting.
Top 50 firms, meanwhile, held onto their clients far better. Only 12% of their clients used a different provider, with 64% getting their advisory work in-house, and switching consideration was lowest among this group.
It’s not about the money
Perhaps the most surprising finding: price wasn’t the reason clients were jumping ship.
The two most common explanations, each cited by 35% of respondents, were that their firm never offered or recommended the service in the first place, or that their firm only handled compliance work for them. Researchers were blunt about the takeaway, noting there is a clear set of reasons why businesses use different providers for services their own accountant is capable of — and price isn’t one of them.
A third of businesses also said speed and responsiveness played a role, with clients craving more proactive advice rather than the traditional, compliance-only relationship.
The good news: clients want to come back
Despite all the fragmentation, the study suggests the business isn’t gone for good. Among companies currently using outside providers, a striking 94% said they would consider bringing that work back to their main accounting firm if it could deliver the same quality.
Part of the problem, researchers found, boils down to simple ignorance. When businesses not currently receiving a given service were asked whether their own accounting firm even offers it, most didn’t say no — they simply weren’t sure, having never had it confirmed either way.
Loyalty is fading fast
The survey also found the old model of client loyalty built on tax filing and compliance work is crumbling. More than half of businesses, 54%, said they’re actively shopping around for alternative providers, while a total of 91% said they’ve at least considered it within the past year.
Adding to the pressure, researchers found businesses are increasingly turning to artificial intelligence for financial guidance. Some 71% said they had acted on a financial, tax or business answer from an AI tool without running it by their accountant in the past year, and only one in 100 businesses believe annual accounts and tax filings will always require a human professional. The report characterized this as a separate trend running alongside — not directly causing — the broader shift toward outside providers.
Businesses want new pricing — and they’re willing to pay for it
The billable hour, long the standard in the accounting world, is falling out of favor, the survey found. Fewer than one in five businesses said it was their preferred billing method, putting it behind both value-based pricing, favored by 19%, and fixed annual fees, preferred by 23%.
Despite the frustration over service gaps, businesses appear ready to loosen their purse strings. A whopping 92% said they’d be willing to spend more if it meant getting the services they actually need from their accountants, with the average business willing to boost its spending by 16% above current levels.
