How to Choose an Accountant for Your Small Business (UK 2026)

The right accountant saves you money and stress. The wrong one costs you both — in overpaid tax, missed deadlines, surprise invoices and hours spent chasing replies that never come. Yet choosing one can feel like guesswork, partly because in the UK almost anyone can call themselves an “accountant” without a single qualification.

This guide cuts through that. Below you’ll find exactly what to look for, the red flags that come up again and again in real client complaints, whether to go local or online, and a clear list of questions to ask before you hire. It’s general guidance to help you choose well — not personal advice for your specific situation.

What to look for in a good accountant

A good accountant is more than someone who files your return on time. When you’re comparing options, weigh up these things:

• Proper qualifications. Because the title “accountant” isn’t protected, qualifications are your first filter. Reputable accountants are members of a recognised professional body — AAT, ICB, ACCA or ICAEW — which means they’re trained, examined, regulated and required to keep up to date. Ask which body they belong to.
• Relevant experience. An accountant who works with businesses like yours — your trade, your size, your structure (sole trader, limited company, contractor, landlord) — will spot opportunities and pitfalls a generalist might miss. Ask who their typical clients are.
• Fixed, transparent pricing. You should know what you’ll pay and what’s included before you commit, with no clock ticking every time you ask a question. Vague pricing almost always leads to surprise bills.
• A named, reachable person. One accountant who knows your business and actually answers the phone beats a faceless call centre or a ticket queue every time. Ask exactly who will handle your work.
• Modern cloud software. Good accountants work in Xero, QuickBooks or FreeAgent, so your records are live, secure and accessible from anywhere — and you’re ready for Making Tax Digital rather than scrambling later.
• No lock-in or exit fees. A confident accountant earns your loyalty with good service, not with contracts that make leaving expensive or hand-overs painful.
• Proactivity. The best accountants don’t just record the past — they flag tax-saving opportunities, warn you about deadlines, and answer “what if?” questions before they become problems.

If an accountant ticks most of these boxes, you’re already ahead of most people choosing on price alone.

The red flags to avoid

These warning signs come straight from the most common complaints people make about their accountants. Spotting them early saves a lot of pain:

• Hourly billing surprises. Being charged for individual emails, calls or “quick questions” makes your bill impossible to predict. One small business owner described being billed per email exchange. If the answer to “what’s included?” is “it depends how long it takes,” be cautious.
• Slow replies — or no replies. Unresponsiveness is the single most common reason people switch accountants: emails ignored for weeks, voicemails that go unreturned, a three-day wait on a support ticket. A cheaper accountant you can never reach is rarely good value.
• Vague quotes. If a firm won’t tell you in writing exactly what’s included and what’s extra, you can’t compare it fairly — and you’ll likely find out the gaps on an invoice.
• Exit or release fees. Charges to leave, or to hand your own records to a new accountant, are a red flag. A good accountant won’t hold your data to ransom.
• Billing for their own mistakes. Being charged to correct an error the accountant made is something real clients report — and something you should never accept quietly.
• No clear qualifications or regulation. If someone can’t (or won’t) tell you which professional body they belong to, treat that as a serious warning sign.

None of these means a firm is dishonest — but every one of them should be cleared up before you sign, not discovered later.

Online vs local accountant: does location matter?

For decades, “find an accountant” meant finding one near you. That’s changed. Today, online accountants serve clients right across the UK using cloud software, video calls, phone and email — and for most small businesses, that works just as well as an office down the road.

• A local accountant offers face-to-face meetings and may know your area’s business scene. The trade-offs can be higher overheads (and fees), and you’re limited to whoever happens to be nearby.
• An online accountant can be picked purely on quality, not postcode. Your records live in the cloud, you can share documents in seconds, and you’re not paying for a high-street office. The key is that they still give you a named person who replies quickly — distance only becomes a problem if support is impersonal.

Ask yourself honestly: when did you last need to sit across a desk from your accountant? For most people, the answer is “rarely.” What matters far more than location is whether you can reach a real person fast, and whether they understand your business. That’s why online works UK-wide — you get the right accountant, not just the nearest one.

Questions to ask before you hire

Use this checklist when you speak to any accountant. Asking every firm the same questions is the fastest way to compare them fairly — and a good one will answer all of them clearly and in writing:

1. Which professional body are you a member of (AAT, ICB, ACCA or ICAEW), and what’s your membership number?
2. Is the price fixed, or could it change during the year?
3. Exactly what’s included — and what would be billed extra?
4. Will I be charged for asking questions by phone or email?
5. Who will actually do my work — and how quickly will you reply when I get in touch?
6. Do you have experience with businesses like mine (my trade, size and structure)?
7. What bookkeeping software do you use, and is it included in the price?
8. Are there any fees to leave, or to hand over my records to a new accountant?
9. How will you help me prepare for Making Tax Digital?
10. Are you registered as an HMRC agent and supervised for anti-money-laundering?

If an accountant answers all ten clearly, you’ve almost certainly found a transparent, professional one. If they dodge several, that tells you something too.

How to check they’re genuinely qualified and regulated

Because anyone can use the title, a few minutes of checking is well worth it. Here’s how to confirm you’re dealing with a real professional:

• Check their professional body membership. Ask which body they belong to and their membership number, then look it up on that body’s online register — AAT, ICB, ACCA and ICAEW all let you verify members.
• Confirm anti-money-laundering supervision. Accountancy firms must be supervised for AML, either by their professional body or HMRC. A legitimate firm can tell you who supervises them.
• Check they’re an HMRC agent. If they’ll be filing tax on your behalf, they should be set up as an HMRC agent so they can deal with HMRC for you properly.
• Look for professional indemnity insurance. Reputable accountants carry it. It’s a fair question to ask.

It’s worth knowing that there are different routes to becoming a qualified accountant — bodies like AAT, ICB, ACCA and ICAEW each have their own qualifications and standards. What matters is that your accountant is genuinely a member of a recognised body and regulated by it, so you know there’s training, ethics and accountability behind the name.

The bottom line

Choosing an accountant isn’t about finding the cheapest quote — it’s about finding someone properly qualified, transparent on price, and easy to reach, with experience of businesses like yours and no nasty surprises in the small print. Run any accountant through the checklist above, verify their qualifications, and you’ll avoid the traps that catch so many small business owners.

Once you’ve switched or settled in, it helps to understand the wider picture too: see how much an accountant costs and what affects accountant fees for a small business, and if you’re moving from your current firm, how to change accountants walks you through it step by step.
