Specialist vs generalist accountant for UK agencies
Most UK agency founders start with a generalist high-street accountant who handles everything from butchers to consultants. As the agency grows, the question becomes whether a specialist agency accountant pays back the fee difference. This is the honest answer.
Generalist accountants are not bad, most are highly competent at compliance work and personable to deal with. The real question is whether the agency-specific complexity in your business has outgrown what a generalist sees on average across their client base. A generalist handling 200 mixed-sector clients sees an agency-tax decision once every few years. A specialist sees it every week.

Generalist accountant is the right choice if
Agencies under £150k revenue with simple structures.
- Sole trader or single-director limited company
- No employees or freelancers
- Standard service model (no R&D, no exit plans, no IR35 exposure)
- You value local relationship over specialist depth
- You have a long-standing relationship with a trusted generalist

- Revenue above £150k with consistent growth
- You engage freelancers (IR35 exposure)
- You build custom tech (R&D credit eligibility)
- Multiple shareholders or co-founders
- You're planning a sale, MBO, or significant exit
- International element (UAE, US clients, cross-border)
- You want one accountant who actually understands your business model
Common questions
What does a specialist actually do differently?
Three concrete things. (1) Sees the patterns: knowing that 7 in 10 digital agencies qualify for R&D credits, that recruitment agencies face specific IR35 mass-determination risk, that creative agencies often mis-value goodwill on sale. (2) Proactive advice: not waiting for you to ask. If your salary split is suboptimal, we model it without prompting. (3) Specialist judgement on edge cases that generalists encounter rarely.
What's the typical £ saving?
Variable. Our typical growth-stage agency client (£500k-£2m revenue) sees £10k-£50k per year in directly attributable tax savings vs a generalist setup. R&D credits account for the largest share. BADR-eligible exits can save six figures. Smaller agencies may not see specialist-pays-for-itself returns yet.
What if my current generalist accountant is good?
Many are. The test isn't whether they're good at compliance, most are. The test is whether they're spotting agency-specific opportunities and risks (R&D, IR35, BADR, multi-shareholder extraction, group structures). If they've never proactively flagged an R&D opportunity, never suggested alphabet shares, and never modelled an exit, you may be leaving money on the table.
How do I tell if I need a specialist now?
Three triggers: (1) you've hit £200k+ revenue and want strategic advice, not just filing; (2) something specialist is coming up (R&D claim, IR35 enquiry, holding co, exit conversation); (3) you've started spending too much of your own time on financial decisions because your accountant can't answer them quickly. Any one is enough.
