Red Flags When Hiring an Accountant UK 2026: 9 Checks to Protect Your SME
Nine Checks to Run Before You Hire an Accountant
The wrong accountant can cost far more than their monthly fee.
Missed filing dates, unclear advice, unexpected charges and poor communication can quickly create stress for a growing limited company. In 2026, that risk is greater as businesses adjust to new digital filing arrangements and increasingly complex compliance expectations.
If you have been searching for an accountant near me, do not choose based on location or price alone. Use the nine checks below to compare potential advisers before you sign an engagement letter.
For straightforward limited-company support, pricing may start at around £85pm+, although the final cost will depend on your turnover, transaction volume, VAT position, payroll, bookkeeping and advisory needs.
1. The firm cannot clearly explain its qualifications
The title “accountant” does not automatically tell you what qualifications, professional oversight or experience a provider has.
Ask whether the accountant or firm is connected with a recognised professional body, such as ACCA, ICAEW, CIMA or AAT. You should also ask whether they hold any practising certificate required for the services they provide.
This does not mean every capable bookkeeper must belong to the same organisation. However, a firm providing limited-company accounts, Corporation Tax and director advice should be transparent about its professional background.
Red flag: they avoid the question, provide vague answers or display professional logos without explaining their membership.
2. There is no proper anti-money-laundering process
A legitimate accountant should complete identity and business checks before taking you on as a client. These checks may include verifying your identity, company ownership, directors, shareholders and the nature of your business.
This can feel like administration, but it is an important safeguard. Accountancy providers must be supervised for anti-money-laundering purposes by an appropriate professional body or HMRC.
Red flag: the accountant says checks are unnecessary, asks you to send sensitive information through an insecure channel or appears unfamiliar with beneficial ownership requirements.
A professional onboarding process is a positive sign, not an inconvenience.
3. The quote is cheap but unclear
A low monthly fee may only cover a narrow part of what your company needs. For example, the advertised price might exclude bookkeeping, VAT returns, payroll, Companies House filing, tax planning or director Self Assessment support.
When you compare accountant services, look at the total expected annual cost rather than the headline monthly figure.
Your written quote should confirm:
- Annual accounts preparation
- Corporation Tax return work
- Companies House filing
- Bookkeeping and reconciliations
- VAT returns, if applicable
- Payroll and pension administration
- Management accounts or forecasting
- Meetings and telephone advice
- Software licence costs
- Additional hourly or project rates
- VAT treatment of the quoted price
Red flag: the firm will not provide a clear written scope, repeatedly uses “from” pricing or cannot explain what may trigger extra charges.
A starting price of £85pm+ may be suitable for a straightforward company, but a growing business should understand exactly what is and is not included.
4. There is no engagement letter
Do not begin work without a proper engagement letter. It should explain the services being provided, your responsibilities, the accountant’s responsibilities, fees, communication arrangements and termination terms.
The engagement letter should also make clear what happens if your records are incomplete, if historic bookkeeping needs correcting or if HMRC opens an enquiry.
Red flag: the accountant wants to start immediately based only on a phone call, text message or informal email.
A written agreement protects both sides and gives you something to refer back to if expectations change.
5. They promise unrealistic tax savings
Good tax planning is legal, practical and based on your company’s actual circumstances. It may involve decisions around salary, dividends, pensions, capital allowances, timing of expenditure or business investment.
Be cautious of anyone who guarantees a specific tax saving before reviewing your records. You should also question advice that relies on complicated arrangements you do not understand.
Ask:
- What assumptions does this advice rely on?
- Is the arrangement suitable for a company of my size?
- What records will I need to keep?
- What are the risks if HMRC challenges the treatment?
- Is the advice included in my fee?
Red flag: guaranteed results, pressure to act immediately or advice that sounds too good to be true.
Your accountant should help you make informed decisions, not encourage you to accept unexplained risks.
6. They are vague about deadlines and 2026 filing changes
Your accountant should be able to explain the key deadlines affecting your limited company and how they are monitored.
For many companies, annual accounts are due at Companies House nine months after the financial year end. Corporation Tax is usually payable nine months and one day after the end of the accounting period, while the Company Tax Return is generally due 12 months after that period ends.
You can check the relevant Company Tax Return deadline guidance.
There is also an important 2026 practical change. The joint HMRC and Companies House filing service has changed, so companies should check HMRC guidance for their circumstances and ask prospective accountants how they handle accounts and Corporation Tax submissions.
Red flag: the accountant cannot explain how they file accounts and CT600 returns in 2026, does not send reminders or blames missed deadlines entirely on clients.
A reliable firm should explain what information it needs from you and when it needs it.
7. They have no clear process for digital records or data security
Limited companies share highly sensitive information with their accountants, including bank details, payroll records, identification documents and tax information.
Ask whether the firm uses:
- A secure client portal
- Multi-factor authentication
- Encrypted document sharing
- Controlled staff access
- Secure backups
- A documented data breach process
- Clear data retention and deletion policies
You should also ask whether you retain access to your accounting software and records if you decide to change accountant.
Red flag: they rely entirely on ordinary email attachments, request passwords by email or refuse to explain who can access your records.
When searching for an accountant near me, remember that a local office does not necessarily mean better security. Check the systems as well as the location.
8. You cannot identify who will actually handle your work
The person who wins your business may not be the person who prepares your accounts. Some firms use internal teams, contractors, overseas staff or specialist providers. This is not automatically a problem, but you should know how the arrangement works.
Ask:
- Who will be my named day-to-day contact?
- Who prepares the accounts and tax returns?
- Who reviews the work before submission?
- Will bookkeeping or payroll be subcontracted?
- Where are subcontractors based?
- How quickly should I expect a response?
- Who will contact me if information is missing?
Red flag: the firm is evasive about who does the work, offers no service standard or tells you that you will only hear from them near a filing deadline.
A growing SME normally needs more than annual compliance. You should have access to someone who can explain your figures and help you plan.
9. They pressure you to hand over excessive control
Your accountant may need access to accounting software or authority to submit returns as your agent. They should not need unrestricted control over your bank account or permission to move money without proper approval.
Keep payment authority, director responsibilities and accounting work separate. You should retain control of your bank accounts, company records and important decisions.
Red flag: the accountant asks for your personal HMRC login, wants sole control of your financial systems or pressures you to sign documents without explaining them.
You should also check the exit terms. Avoid arrangements that include unexplained release fees, make it difficult to access your records or prevent a smooth handover to another adviser.

| Scope | Services included and excluded |
| Cost | Total annual price, including VAT and software |
| Communication | Named contact and response times |
| Technology | Secure systems and 2026 filing capability |
| Advice | Practical support for growth and tax planning |
| Flexibility | Onboarding, scaling and exit arrangements |
This is the best way to compare accountants for small business requirements without being distracted by a low headline price.
