How Much Does an Accountant Cost for a Small Business in 2025?

One of the most common questions small business owners ask is: how much should I be paying my accountant? Whether you are a sole trader just starting out or running an established limited company, understanding what accountancy services cost helps you budget properly and avoid overpaying.

In this guide, we break down the average accountant fees for UK small businesses in 2025, what is typically included, and where you might find better value.

Average UK Accountant Fees in 2025

Accountancy fees vary enormously depending on the complexity of your business, your location, and whether you use a traditional high-street firm or an online provider.

Here are the typical annual ranges:

Business Type	Annual Fee Range
Sole trader (simple)	£150 – £400
Sole trader (VAT registered)	£400 – £800
Limited company (micro)	£500 – £1,200
Limited company (small)	£1,000 – £2,000+
Limited company (VAT + payroll)	£1,500 – £3,500+

These figures represent fixed-fee packages, which are how most small business accountants now price their services. Location matters too — accountants in London and the South East typically charge 20-40% more than those in other regions.

What Is Typically Included?

A standard small limited company accountancy package usually covers:

• Year-end statutory accounts — prepared in the format required by Companies House
• Corporation Tax return (CT600) — calculated and filed with HMRC
• Company tax planning advice — basic salary vs dividend guidance
• Bookkeeping review — checking your records are accurate (though not always full bookkeeping)
• Self Assessment tax return — for the director(s), often at an additional cost of £150-£300 each
• Companies House filing — annual accounts and Confirmation Statement
• Ad-hoc support — email and phone queries throughout the year

VAT returns are usually an add-on costing £50-£100 per quarter, and payroll is typically £5-£15 per employee per month.

Hourly vs Fixed Rates

Accountants broadly charge in two ways:

Fixed monthly/annual fees are the most popular model for small businesses. You know exactly what you will pay, and services are clearly defined. This model works well when your needs are predictable.

Hourly rates typically range from £30-£60 per hour for junior staff at smaller firms, up to £150-£300+ per hour for partners at mid-size or large practices. Hourly billing can quickly escalate if your affairs are complex or if you ask lots of questions.

For most small businesses, a fixed-fee arrangement offers better value and predictability. Just make sure you understand exactly what is and is not included.

Online Accountants vs High-Street Firms

The rise of online accountancy practices has significantly disrupted traditional pricing. Here is how they compare:

Online accountants (such as Crunch, Gorilla, or SJD):

• Typically 30-50% cheaper than high-street equivalents
• Cloud-based platforms with real-time dashboards
• Communication primarily via email, chat, or video call
• Packages often start from £50-£100 per month for limited companies
• Good for straightforward businesses with standard needs

High-street accountants:

• Face-to-face meetings and local knowledge
• Often better for complex situations (multiple companies, property portfolios, international issues)
• More likely to offer proactive tax planning
• Relationship-based service with a dedicated accountant
• Higher overheads reflected in higher fees

Neither option is universally better. The right choice depends on the complexity of your business and how much personal interaction you value.

Hidden Costs to Watch Out For

Many business owners are caught off guard by costs that sit outside their standard package:

• Ad-hoc queries — some accountants charge for every phone call or email outside the package scope, typically £50-£150 per query
• Year-end adjustments — if your bookkeeping is messy, expect additional charges of £200-£500+ for "accounts preparation" work
• HMRC correspondence — dealing with tax investigations or enquiries is almost never included and can cost £1,000+
• Company formations, share changes, or director appointments — usually £100-£300 per event
• Late fees — if you provide information late and the accountant has to rush, many charge a premium
• Software subscriptions — some accountants require you to use specific software (Xero, QuickBooks) at your own cost (£15-£40/month)

Always ask for a full schedule of fees before engaging an accountant, including what happens when you need something outside the standard package.

Do You Actually Need a Full-Service Accountant?

Here is the question many small business owners do not ask: do you need everything a traditional accountant provides?

If your business is relatively straightforward — you provide services, have simple expenses, and no complex tax structures — you may be paying for expertise you do not use.

Many business owners really need just a few core documents each year:

• Annual accounts for Companies House
• A CT600 Corporation Tax return
• A personal Self Assessment return
• Quarterly VAT returns (if registered)

This is where modern alternatives can offer significant savings. TaxDocs enables you to generate professional tax documents starting from just £29 per document, using AI-powered extraction from your bank statements and financial records. For businesses with straightforward affairs, this can reduce your annual compliance costs from over £1,000 to a fraction of that amount.

How to Get the Best Value

Whether you stick with a traditional accountant or explore alternatives, here are tips for keeping costs down:

• Keep immaculate records — the cleaner your bookkeeping, the less your accountant charges for preparation work
• Use cloud accounting software — Xero, FreeAgent, or QuickBooks reduce manual processing time
• Batch your questions — instead of calling every week, save non-urgent queries for a monthly catch-up
• Review your package annually — your needs change; make sure your package still fits
• Get multiple quotes — accountancy is competitive, and switching is easier than you think
• Consider a hybrid approach — use TaxDocs for document generation and an accountant only for advisory work
