How to Choose an Accountant in the UK — Costs, Services & Red Flags

How to Choose an Accountant UK — Costs, Services & Red Flags

A good accountant does more than file your tax return. They keep you compliant, help you plan, and save you time you could spend running your business. A bad one costs you money, misses deadlines, and leaves you to deal with HMRC. This guide shows how to choose an accountant UK: when you need one, what qualifications to look for, what you should expect to pay, and the warning signs to walk away from.

When do you need an accountant?

You can do your own accounts, and many people with simple finances do. But an accountant is worth the fee when your finances get complicated, or a mistake would be costly. Consider hiring one if you are:

• Self-employed — income, expenses or tax bill growing, or unsure what you can claim.
• Running a limited company — year-end accounts, Corporation Tax, payroll and Companies House filings.
• A landlord — rental income, especially more than one property, or thinking about a limited company structure.
• Registered for VAT, or approaching the £90,000 VAT registration threshold.
• Dealing with Making Tax Digital (MTD) — digital records and compatible software for VAT and, from April 2026, for Income Tax for many self-employed people and landlords.
• Employing staff — payroll, auto-enrolment pensions and PAYE every month.
• Planning a big decision, such as buying a business, taking on a partner, or selling up.

If you are an employee with only PAYE income and no other income, you probably do not need an accountant at all. If you have a side income, rental income or capital gains, a one-off appointment may be enough.

Qualifications to look for

Anyone can call themselves an accountant in the UK — the title is not protected by law. Qualifications and membership of a professional body matter: they mean the person has passed exams and follows professional standards.

• ACA — Chartered Accountant (ICAEW). The best-known qualification for accountants in practice.
• ACCA — Chartered Certified Accountant. Widely recognised, common in small business practices.
• CIMA — Chartered Management Accountant. Focused on management accounting and business decisions.
• CTA — Chartered Tax Adviser (CIOT). The specialist tax qualification — valuable if your situation is tax-heavy.
• AAT — Accounting Technician. Respected, often held by bookkeepers and small-business accountants.

Also check the firm is supervised for anti-money-laundering purposes and holds professional indemnity insurance. You can check membership through the professional body’s online register. Experience with businesses like yours matters just as much as qualifications.

What services should you expect?

A typical small-business service includes:

• Self Assessment tax returns — prepared and filed by the 31 January deadline.
• Year-end accounts — annual accounts, whether self-employed or a limited company.
• Corporation Tax — working out the tax, filing the CT600 return with HMRC, and filing accounts with Companies House.
• VAT returns — quarterly returns, keeping records compliant with Making Tax Digital for VAT.
• Payroll — monthly payroll, PAYE and National Insurance, and auto-enrolment pensions.
• Bookkeeping — day-to-day records in order, bank statements reconciled.
• MTD software — set up on cloud software such as Xero, QuickBooks or FreeAgent, with training on how to use it.
• Advice — questions during the year, not just at year-end: how much to put aside for tax, salary or dividends, whether to register for VAT, how to plan for growth.

Check what is included before you sign up: a cheap fee excluding VAT, payroll and advice can cost more than an all-inclusive package.

How fees are charged

• Fixed fee — a set price for a defined job, such as a Self Assessment return or a year’s accounts. The most common arrangement for small businesses, and it means no surprises.
• Monthly package — a fixed monthly payment covering a bundle of services. Good for budgeting.
• Hourly rate — for one-off advice or unusual work. Qualified accountants typically charge £60 to £150 an hour, depending on experience and location.

Always get the fee in writing before work starts, in an engagement letter listing what is included and what is extra. If quoted excluding VAT, ask for the total including VAT.

How much does an accountant cost?

Fees vary by location, complexity and business size; London is usually higher. The figures below are typical UK market ranges from fee guides — not quotes, and not official rates. Always get a written quote for your own situation.

Accountancy fees for a business are normally a tax-deductible business expense, so they reduce your taxable profit. Purely personal tax work — for example, a tax return for personal investment income with no business element — usually is not deductible.

Questions to ask before you hire

Most firms offer a free first call — a good first step in how to choose an accountant UK. Ask:

1. Is the fee fixed, and in writing? What is included, and what costs extra?
2. Who will be my day-to-day contact? Will I deal with the same person each time?
3. What software do you use? Do you work with the cloud software I already use?
4. How quickly do you respond? What is a realistic turnaround for a question?
5. What experience do you have with businesses like mine?
6. Are you qualified and a member of a professional body? Do you hold professional indemnity insurance?
7. How do you handle deadlines? How do you make sure my tax return is filed on time?
8. What happens if HMRC opens an enquiry? Is dealing with it included in the fee?
9. What do you need from me, and when? A good accountant gives you a clear list and a timetable, not a last-minute panic in January.

A good accountant explains things in plain English and is honest about what they do not know. If they dodge questions or pressure you to sign on the spot, walk away.

Red flags to watch for

• No qualifications and no professional body membership, with no clear explanation of their experience.
• No fixed fee and no engagement letter — nothing in writing means no protection when the bill arrives.
• Promises of refunds or guaranteed tax savings — no honest accountant can promise a refund before seeing your records.
• Asks you to sign blank forms, or documents you have not read. Never do this.
• No professional indemnity insurance — if they make a mistake, nothing covers your loss.
• Encourages you to hide income or claim expenses you know are not genuine — that is tax evasion, and you, not the accountant, are responsible to HMRC.
• Poor reviews, or a pattern of complaints about missed deadlines and unanswered calls.
• Uncontactable at deadline time — January is the busiest month of the year.

Trust your instinct: if something feels off in the first conversation, it rarely improves.

DIY or hire an accountant?

Doing it yourself costs nothing but your time, and for simple finances it is perfectly realistic. Hiring an accountant makes sense when your time is worth more than the fee, or a mistake could cost more than the accountant charges: a missed deadline alone can cost £100 in penalties. A middle option is to do your own bookkeeping and hire an accountant for the year-end work only.

Switching accountants

Switching is normal, and your new accountant will usually handle most of the handover:

1. Tell your old accountant you are moving, in writing. You do not have to give a detailed reason.
2. Your new accountant sends a professional clearance letter to the old one, asking whether there is any reason they should not take you on.
3. Your old accountant must hand over your records — your accounts, tax returns, and working papers that belong to you. They cannot hold your records hostage over an unpaid fee dispute.
4. Authorise the new accountant with HMRC — usually through a 64-8 form or online authorisation — so they can act for you.

If your old accountant is slow to hand things over, your new accountant can chase it.

What to check now

• Decide what you need: a one-off tax return, year-end accounts, or an ongoing monthly package.
• Shortlist two or three firms that work with businesses like yours.
• Check each accountant’s qualifications and professional body membership.
• Ask for a fixed fee in writing, including VAT, and a list of what is included.
• Ask who your day-to-day contact will be and how quickly they respond.
• Check reviews and ask whether they hold professional indemnity insurance.
• If you are switching, ask your new accountant to handle the handover and HMRC authorisation.

Frequently asked questions

Do I need an accountant if I am self-employed?
Not by law, but most self-employed people find one worthwhile once their income grows. If your finances are simple, you can file your own Self Assessment.

How much does an accountant cost for a small business?
A simple Self Assessment return typically costs £150–£400 a year, self-employed accounts £250–£1,000+VAT a year, and a limited company package £60–£250+VAT a month. Always get a written quote — fees vary by location and complexity.

What qualifications should my accountant have?
Look for ACA, ACCA or CIMA, or CTA for specialist tax advice. AAT is a respected qualification for bookkeepers and small-business accountants.

Are accountant fees tax-deductible?
Accountancy fees for a business are normally a tax-deductible business expense, which reduces your taxable profit. Purely personal tax work usually is not deductible.

How do I switch accountants?
Tell your old accountant in writing, then let your new accountant handle the handover: a professional clearance letter, a request for your records, and authorisation to act for you with HMRC. Your old accountant must hand over your records.
