What drives fee differences?

Even for the same headline service, prices vary widely. Common drivers include:

  • Quality of records: tidy bookkeeping in Xero/QuickBooks costs less to work with than shoebox receipts
  • Complexity: multiple income sources, foreign income, share schemes, capital gains, partnerships, group structures all add cost
  • Industry specialism: regulated sectors (FCA, charity, healthcare, construction CIS) need specialist knowledge
  • Service standard: high-touch client experience and proactive advice cost more than reactive compliance only
  • Software inclusion: bundled software adds £15 to £50 per month to package prices
  • Location: London and Home Counties typically 20% to 40% above national averages
  • Firm size: Big Four and large mid-tier firms charge significantly more than small or solo practices

What you typically get for a £150 to £250 monthly retainer

  • Year-end accounts and corporation tax return
  • One director's self-assessment
  • Confirmation statement
  • VAT returns under MTD
  • Payroll for one or two directors
  • Email and phone support, response within 1 to 2 working days
  • Often: bundled accounting software subscription

What you typically get for £300 to £500+ monthly

  • All of the above
  • Full bookkeeping done by the practice
  • Higher-volume payroll (e.g. 3 to 10 employees)
  • Quarterly management accounts and review meetings
  • Tax planning conversations and proactive advice
  • Faster response times

Compare like-for-like

Fee comparisons only work when the scope of services is matched. A £100/month "limited company" deal that excludes bookkeeping, payroll and the director's tax return is not equivalent to a £250/month package that includes them all.

How to use these benchmarks if you're a client

If you are a small business owner deciding whether your accountant's fees are reasonable, look at:

  • What services are included (and excluded)
  • Whether software is bundled
  • The qualification and licensing of the firm (ICAEW, ACCA, AAT)
  • The standard of communication, responsiveness, and proactive advice
  • Whether the firm specialises in your sector

Headline price alone is rarely the right basis to choose. The cheapest accountant is often the most expensive over time.

How to use these benchmarks if you're a practitioner

If you are setting prices for your practice, use these ranges as a sanity check rather than an instruction. Your specific costs (premises, software stack, AML burden, PII), local competition, and client base will determine the right level. Many sole practitioners find the upper half of these ranges achievable with strong specialism and a clear value proposition.

  • The biggest fee drivers are records quality, complexity, sector specialism and service standard

Frequently asked questions

How much does an accountant cost for a small limited company in the UK?
For a typical owner-managed small company, expect £150 to £400 per month or £900 to £2,000+ per year, including accounts, corporation tax, the director's self-assessment, and basic VAT and payroll.

How much does it cost to do a self-assessment?
£150 to £400 for a simple return; more for complex returns with multiple income sources, capital gains or foreign income.

Are accountancy fees tax-deductible?
Fees relating to your business or self-employment are generally allowable as a business expense. Personal tax return preparation for a non-business return is not normally deductible.

Why are accountants cheaper online than locally?
Online practices benefit from cloud automation, scale and lower overheads. Their fees are often 10% to 30% lower than traditional high-street firms, but service models differ; weigh price against responsiveness and access to a named adviser.

Are R&D claim fees on contingency normal?
Yes, contingency or success-based fees of 10% to 25% of the credit are common, although fixed-fee R&D services are increasingly available and often better value for larger claims.
