How much does an accountant cost for a small business?
How much does an accountant actually cost a UK small business? Real fixed-fee ranges for sole traders, limited companies and growing firms, plus what's usually included.
Short answer: for a UK small business, expect £30 to £60 a month if you're a sole trader, £100 to £250 a month for a small limited company, and £300+ a month for growing firms that need bookkeeping, VAT and payroll bundled in.
Below is what actually drives the fee, what a fair package includes, and how to make sure you're not overpaying.
Fixed monthly fees are now the norm
Ten years ago, small business accounting was billed by the hour. That's mostly gone. Most modern firms (Calibra included) charge a fixed monthly fee so you know the full year's cost upfront and can budget for it.
Fixed fees also change the relationship. When the meter isn't running, you're happy to pick up the phone or send a quick question, which is usually where the real value shows up.
Typical UK price ranges
Sole trader: £30 to £60 a month
Usually covers:
- Self Assessment tax return.
- Basic bookkeeping tidy-up or review.
- Xero, QuickBooks or FreeAgent subscription (sometimes).
- Email support during the year.
Higher-turnover sole traders or those close to the VAT threshold tend to sit at the top of that range.
Small limited company: £100 to £250 a month
Usually covers:
- Statutory year-end accounts filed with Companies House.
- Corporation tax return (CT600).
- Confirmation statement filed with Companies House.
- Self Assessment for one director.
- Advice on salary vs dividends and director drawings.
- Cloud accounting software.
- Ongoing email and call support.
VAT-registered companies typically add £30 to £80 a month on top for quarterly VAT returns under Making Tax Digital.
Growing company: £300+ a month
Usually covers everything above plus:
- Full bookkeeping done for you (not just reviewed).
- Payroll for a small team and pension submissions.
- Monthly or quarterly management accounts so you can see profit and cash properly.
- Regular advisory calls, tax planning, and cash flow forecasting.
Fees scale with transaction volume, headcount and how hands-on you want the accountant to be.
What actually drives the fee
Six things move the price:
- Business structure. Limited companies cost more than sole traders because there are more filings.
- VAT registration. Quarterly returns and MTD compliance add cost.
- Payroll. Priced per employee, per month, typically £4 to £10 a head.
- Bookkeeping volume. More transactions equal more work, whether that sits with you or the accountant.
- How much of it they actually do. "Review your bookkeeping" is cheaper than "do your bookkeeping for you". Make sure the quote is clear on which.
- Advisory work. Regular management accounts and forecasting cost more than pure compliance, and are usually worth it once turnover is over £250k.
Hourly, fixed fee or ad-hoc: which is best?
- Fixed monthly fee. Best for almost every small business. Predictable, unlimited support, one direct debit.
- Hourly. Fine for one-off pieces of work (e.g. sorting out a historical mess) but not a long-term arrangement.
- Ad-hoc. Cheapest sticker price, but you'll hesitate to call your accountant because every minute costs. False economy.
Is it worth it?
For a typical limited company that's £1,200 to £3,000 a year. The return usually comes from three places:
- Tax saved through better structuring of salary, dividends, allowances and pension contributions.
- Penalties avoided on late or incorrect filings, which routinely run to hundreds of pounds per slip.
- Time reclaimed so you're not spending weekends reconciling a bank feed.
Most owners find the fee pays for itself several times over. There's more context in our guide to what an accountant actually does and in the overview of how we work with small businesses.
How to make sure you're not overpaying
- Ask for the quote in writing with everything listed.
- Make sure software subscriptions are either included or clearly excluded.
- Check whether payroll is priced separately.
- Confirm response times (24 hours for email is a fair benchmark).
- Watch for firms that quote low then bill "extras" for every phone call.
