Most UK founders choose their first accountant the way they pick a router — they take a recommendation, sign up, and forget about it until something goes wrong. That works until it doesn't. Here is how to choose an accountant who scales with the business rather than slowing it down: the credentials that actually matter, the questions to ask before signing, and the red flags worth walking away from.
The short answer
For a UK founder, the right accountant has three things: the right qualification (ACCA, ACA, or CIMA), real experience with businesses your size and structure, and a working understanding of the software stack you actually use. Anything else — fancy offices, big-firm logos, premium pricing — is decoration.
1. Qualification
UK accountancy is a regulated profession. Three qualifications carry full weight:
- ACCA (Association of Chartered Certified Accountants) — broad, internationally recognised, dominant in the UK SMB advisory market.
- ACA(Institute of Chartered Accountants in England & Wales) — historically associated with audit and larger businesses, increasingly common in advisory work.
- CIMA (Chartered Institute of Management Accountants) — focused on management accounting and finance-business-partner roles; less common in pure tax and compliance work.
AAT (Association of Accounting Technicians) is a useful bookkeeping and finance qualification but is not a chartered accountancy designation. An AAT-qualified bookkeeper can be excellent at bookkeeping; you still want a chartered accountant signing off on the year-end accounts and tax return.
Verify the qualification — the firm should be on the public register of its body. ACCA, ICAEW, and CIMA all publish searchable directories.
2. Fit for your business
A great accountant for a property landlord will not necessarily be the right accountant for a SaaS founder, a consultancy, or a regulated business. Specialism matters more than firm size. Three sub-questions:
Do they work with businesses your size?
A firm whose typical client is a £50m turnover business will treat your £200k turnover as a side job. A firm whose typical client is a sole trader will not have the depth for a scaling SME with payroll, VAT, and R&D claims.
Do they understand your sector?
A construction business needs CIS-aware accounting. A regulated business needs AML-aware accounting. A SaaS business needs revenue-recognition-aware accounting. Asking "have you worked with businesses like ours?" cuts the candidate list in half.
Do they handle the structures you'll need?
If you might raise EIS/SEIS investment, set up an EMI option scheme, claim R&D tax credits, or eventually sell the business, ask explicitly about each. Some accountants do all of these routinely; others outsource them or have never touched them.
3. Software and operating model
UK accounting moved into Making Tax Digital years ago, and modern firms run on cloud software. The accountant should:
- Be comfortable with at least one of Xero, QuickBooks, or FreeAgent — and ideally certified.
- Have a clear stance on bookkeeping: do they do it, do they want you to, or do they prefer a third party? All three are valid; the wrong answer is "we'll figure it out".
- Use a portal or shared workspace for documents, not email attachments.
- Respond within agreed turnaround times. Get the SLA in writing.
Questions to ask before signing
- What's your monthly fee, and what does it include?
- What's outside the scope, and what does that cost on top?
- Who will I actually deal with day-to-day? (Often not the partner who pitched.)
- How long do you take to respond to emails? To complete year-end accounts?
- Do you handle bookkeeping, or do you want me to?
- Have you handled R&D claims / EMI / EIS / share schemes?
- What's your view on Making Tax Digital, and how does that affect me?
- Can I see a sample monthly management report?
- Who covers my work if my main contact is on leave?
- Do you offer fixed pricing, or is everything on the clock?
Red flags
- Vague pricing. "It depends" is fine for unusual work; for monthly compliance it should be a fixed number.
- No written engagement letter. Required by all professional bodies. Walk if it's not produced.
- Slow filing track record. Ask for stats on their on-time filing rate. A serious firm will know.
- Pressure to sign quickly. Real firms know you're going to compare them with at least one other. They'll give you time.
- Unfamiliarity with your software. If they don't already know the tool you use, they'll either learn it on your time or push you onto theirs.
What an accountant won't do
Even a great accountant is not your finance director, your bookkeeper, your CFO, or your business advisor. Be clear about the boundaries. If you need management accounts, forecasting, and capital strategy, that's a different brief — sometimes the same firm offers it; often it doesn't.
Compliance and advisory are also different categories of work. Compliance is what keeps the company legal: filings, accounts, VAT, payroll. Advisory is what helps the business make better decisions: tax planning, structure, share schemes, exit preparation. A good accountant offers both clearly priced; a weaker one mixes them and bills surprise hours.

Frequently asked questions
How much does a UK accountant cost for a small limited company?
Monthly compliance packages for a UK limited company typically run £80–£300 per month, covering year-end accounts, corporation tax return, confirmation statement, and director self-assessment. VAT, payroll, R&D claims, and advisory work are usually priced on top. Sole traders pay less; companies with payroll or VAT pay more.
ACCA vs ACA — which qualification matters more for UK founders?
Both are equivalent in legal standing for UK accounting and tax work. ACCA is more common in the UK SMB and advisory market; ACA is more common in audit and larger-business advisory. For a typical UK founder the choice between an ACCA-qualified firm and an ACA-qualified firm is a wash — fit, sector knowledge, and software competence matter more.
Do I need an accountant to file my own UK company accounts?
Legally no — the directors can file the company's accounts themselves. In practice, almost all UK limited companies use an accountant because the accounts and corporation tax return must be in iXBRL format, late filings carry penalties, and the rules change frequently. A typical compliance package costs less than the time a non-specialist would spend self-filing.
When should I switch accountants?
If filings are late, queries take days to answer, software is being avoided, or the firm doesn't understand a structure your business actually needs (R&D, EIS, share schemes), it is time to move. Switching is administratively straightforward — the new firm sends a professional clearance letter to the old one, and the old firm transfers the records.
