A small business accountant in the UK typically costs £60-£250 +VAT a month for a limited company. Here's exactly what drives the price.
A small business accountant is a qualified professional who prepares your statutory accounts and tax returns, keeps you compliant with HMRC and Companies House, and advises you on tax, cashflow and the financial decisions in front of you.
In practice, that covers two different jobs. The first is compliance - the returns and filings you are legally required to submit. The second is advice - helping you use the numbers to run the business better. Cheaper services tend to cover only the first; the value of a good accountant is in the second.
Most are members of a professional body such as the Institute of Chartered Accountants in England and Wales (ICAEW) or the Association of Chartered Certified Accountants (ACCA), which sets the standards they work to.
A small business accountant costs £60-£250 +VAT per month for a typical limited company, and £150-£400 +VAT per year for a sole trader. The table below shows typical UK fixed-fee ranges by business stage.
Business type - Typical fee - What's usually included
Sole trader - £150-£400 /yr - Year-end accounts, Self Assessment tax return
Small Ltd (under £100k) - £60-£120 /mo - Statutory accounts, corporation tax, director's return, software
Growing Ltd (£100k-£500k) - £120-£250 /mo - Above, plus VAT returns and light advisory
Established Ltd (£500k+) - £250-£600+ /mo - Above, plus monthly management accounts and adviser meetings
Services beyond core accounts and tax are usually priced separately. Typical UK ranges:
Your fee reflects the workload your accounts create, not the size of the firm. Five factors move the price the most:
For most small businesses, a fixed monthly fee is the better choice: it is predictable, includes ongoing support, and removes the disincentive to pick up the phone. Hourly billing only tends to win for one-off pieces of work.
Model - Best for - Watch out for
Fixed monthly fee - Ongoing support, easy budgeting, unlimited questions - Check what's in scope vs charged extra
Hourly billing - One-off advice or a defined project - Unpredictable; can discourage you from asking
Per service - A single filing, e.g. one tax return - No year-round relationship or planning
Yes - for most limited companies and growing businesses, a good accountant pays for itself. The fee buys three things: correct, on-time filings that avoid Companies House and HMRC penalties; tax planning that legally reduces what you owe; and time back to run the business.
The right question isn't “what does an accountant cost?” - it's “what does not having one cost me in missed relief, penalties and bad decisions?”
The value is clearest once there is real tax to plan for. A sole trader with a small side income may reasonably file their own return; a VAT-registered company with staff and irregular cashflow rarely should.
Compare on fit and scope, not just headline price. Work through these six steps:
You can, but most limited company owners find an accountant saves more in tax, penalties and time than they cost - and the fees are tax-deductible.
Yes. Fees for preparing your business accounts and tax are an allowable business expense, so they reduce your taxable profit.
Most UK firms, including Clearsight, now charge a fixed monthly fee, so the cost is predictable and spread evenly across the year.
Higher turnover, more transactions, VAT registration, payroll and extras like monthly management accounts all add to the workload and the fee.
