Average Cost of an Accountant for Small Business UK
Most small businesses pay somewhere between £150 and £2,000 a year, depending on their structure and how much support they need.
Sole traders with simple affairs usually sit at the lower end. Limited companies with payroll, VAT, and bookkeeping needs sit higher.
A dormant company, which isn’t trading yet, costs the least to support since there’s little financial activity to report.
Understanding these ranges is the first step. The next is knowing how they translate into what you’d actually pay in a city like London.
Small Business Accountant Cost in London: What to Expect
London-based firms often price close to the national average, though central London practices can charge a premium for in-person meetings and larger support teams.
Here’s a realistic look at typical small business accountant cost in London for individual services.
A self assessment return filing usually starts from around £199, while annual company accounts for a small limited company start from £299. If your company isn’t trading yet, dormant company accounts cost far less, often from £49, since there’s little to report.
VAT-registered businesses should budget for VAT return filing, which typically runs between £75 and £250 per quarter. Businesses with staff also need to factor in payroll processing, usually priced per employee and billed monthly, alongside ongoing bookkeeping services, which are priced by transaction volume rather than a flat fee.
Many London accountants now offer digital-first service, which keeps overheads lower than a traditional office-based model. That’s part of why fixed-fee pricing has become more common.
If your business needs several of these services together, bundled packages are usually cheaper than paying for each one separately.
What Affects Accountant Pricing?
Several factors push the price up or down, and knowing them helps you understand any quote you’re given.
Business Structure
Sole traders generally cost less to support than limited companies. Limited companies have extra statutory obligations, like filing annual accounts with Companies House, which adds work.
Number of Transactions
More sales, expenses, and bank transactions mean more bookkeeping hours. A business processing hundreds of transactions a month will cost more than one processing a handful.
VAT Registration
VAT-registered businesses need quarterly returns filed under Making Tax Digital rules. This adds a recurring cost that non-VAT businesses don’t have.
Payroll and Staff
Running payroll for employees adds a monthly cost, usually scaled by headcount. A business with five staff pays more than a sole director with none.
Level of Advisory Support
Basic compliance, meaning just filing what’s legally required, costs less than ongoing tax planning and business advice.
Fixed Fee vs Hourly Rate: Which Is Better?
For most small businesses, fixed fees work out better than hourly billing.
Fixed fee accounting gives you a set price for a defined scope of work. You know what you’re paying upfront, and there are no surprise invoices.
Hourly billing suits open-ended work, like a complex HMRC enquiry or a one-off consultation, where the time needed isn’t predictable.
For routine tasks like tax returns, VAT filing, and annual accounts, ask specifically whether a firm offers fixed fees. It’s one of the simplest ways to protect your budget.
What’s Usually Included in an Accountant’s Fee?
Not every accountant fee covers the same things, so it pays to check exactly what’s included before comparing quotes.
A standard package usually includes:
- Preparation and filing of the relevant return or accounts
- Basic email or phone support for questions
- Reminders ahead of filing deadlines
- Confirmation once your filing has been submitted
Things that often cost extra include:
- HMRC investigation support
- Complex tax planning or restructuring advice
- Bookkeeping beyond a set transaction limit
- Same-day or urgent turnaround requests
Always ask for a written breakdown before signing up. It prevents disagreements about scope later.
The Real Cost of Not Hiring an Accountant
Trying to save money by skipping professional help can backfire quickly.
Companies House imposes automatic late filing penalties starting at £150 and rising to £1,500 for accounts delivered more than six months late, according to official GOV.UK guidance. These penalties double if you file late two years running.
That’s before factoring in missed tax reliefs, incorrect filings, or the hours spent untangling records that weren’t kept properly the first time.
For many small businesses, the accountant’s fee ends up costing less than the mistakes it prevents.
How to Get the Best Value for Your Money
Getting good value isn’t about finding the cheapest quote. It’s about matching the service to what your business actually needs.
- Compare at least three quotes before deciding
- Ask what’s included and what counts as an extra charge
- Check whether pricing is fixed or hourly
- Confirm the accountant is qualified through ICAEW, ACCA, or AAT
- Ask how quickly they respond to questions
- Request references from similar-sized businesses
A firm that answers these clearly, without hesitation, is usually a safer choice than one offering the lowest price with no detail behind it.
Cost Comparison Table

FAQ
What is the average cost of an accountant for a small business in the UK?
Most small businesses pay between £150 and £2,000 a year, depending on whether they’re a sole trader or a limited company with VAT and payroll needs.
Is it worth paying for an accountant as a small business?
Yes, for most businesses. The cost is often lower than the penalties, missed reliefs, and time lost from handling compliance without professional support.
How much does a self assessment tax return cost in London?
Fixed-fee self assessment filing in London typically starts from around £199, depending on the complexity of your income sources.
Do small limited companies pay more than sole traders?
Generally yes. Limited companies have extra statutory filing requirements, like annual accounts with Companies House, which adds to the workload and cost.
What’s the difference between fixed fee and hourly accounting?
Fixed fee means a set price for defined work, which is predictable. Hourly billing charges for time spent, which suits unpredictable or complex work.
Does VAT registration increase accounting costs?
Yes. VAT-registered businesses need quarterly returns filed under Making Tax Digital, which adds a recurring cost most non-VAT businesses don’t have.
Can I negotiate accountant fees?
Some firms offer discounts for bundled services or annual upfront payment. It’s reasonable to ask, especially if you need multiple services together.
What happens if I file my accounts late?
Companies House applies automatic penalties starting at £150, rising to £1,500 for delays over six months, and these double for consecutive late filings.
Key Takeaways

Conclusion
The cost of an accountant for a small business in the UK depends heavily on your structure and the services you need, but the right fit rarely comes down to price alone.

If you’re ready to compare options, working with an experienced provider like Digifiling can help you find pricing that fits your budget without cutting corners on compliance.
