“How much does an accountant cost in the UK?” is the most-Googled question in our industry, and the most-dodged. Most firms refuse to give numbers without a sales call. Here’s the honest answer, with real 2026 figures broken down by business type, what affects the price, and how to spot when you’re being overcharged.

UK accountant costs at a glance (2026)

  • Sole trader / freelancer: £30–£100/month, or £200–£500 one-off for a Self Assessment.
  • Small limited company: £100–£300/month for full compliance.
  • Growing SME (£250k–£2m turnover): £300–£1,000+/month.
  • Hourly rates: £25–£60 (junior bookkeeper) to £150–£300+ (senior tax advisor).
  • Tax Falcon’s plans start at £99/month with no hidden fees.

Typical UK accountant costs by business type

The honest answer to “what does an accountant cost” is “it depends” — but it depends on a few specific things you can predict. Here’s what actual UK businesses pay in 2026, based on data from the major industry bodies and our own client base.

Sole traders and freelancers

If you’re a sole trader, freelancer, or contractor with one revenue stream and turnover under the VAT threshold, you’re at the simpler end of the market.

You should expect this to include digital bookkeeping software, bank feed setup, expense tracking, and your annual tax return. Anything less and you’re paying for a glorified filing service.

Small limited companies (under £250k turnover)

This is the meaty middle of the UK accounting market. A typical limited company with one or two directors, a handful of employees, and standard B2B or B2C revenue should expect:

Tax Falcon’s Compliance plan at £99/month sits at the lower end of this range; our Growth plan at £149 covers most operating limited companies.

Growing SMEs (£250k–£2m turnover)

Once you’re past the £250k mark — usually with employees, multiple revenue lines, and proper P&L management — you need a different relationship with your accountant. Expect:

Specialist niches

Some sectors carry premium pricing because they need specialist knowledge:

What actually drives the price

Five factors explain almost all the variation in UK accounting fees:

1. Transaction volume

Bookkeeping cost scales roughly linearly with the number of transactions per month. A consultancy invoicing twice a month is much cheaper to bookkeep than an Amazon seller with thousands of orders. Honest accountants will price-point on transaction volume, not gut feel.

2. Number of revenue streams

Two bank accounts, three Stripe payouts, a PayPal feed, and an Amazon settlement is five reconciliations a month. Each is friction. If you have multiple platforms, expect a higher fee — but make sure your accountant is using automated bank feeds rather than manual statement entry.

3. VAT and payroll complexity

VAT-registered? Add £30–£60/month. Operating PAYE for staff? Add £6–£15 per payslip. Running both, plus pension auto-enrolment, plus benefits-in-kind reporting, can easily double a base fee.

4. How “involved” you want them to be

The cheapest fee gets you year-end compliance and not much else. Mid-tier fees buy regular contact, proactive tax planning, and someone who picks up the phone. Premium fees buy a finance partner — quarterly strategic reviews, scenario modelling, board-level reporting.

5. Geography

London and the South East run 15–25% above national average. Online-first firms (us included) flatten the geographic gap because we operate at scale.

A good accountant should save you more than they cost — usually within the first six months.

Hourly vs fixed-fee — which is better for you?

The industry has been moving away from hourly billing for a decade, and for good reason: hourly fees punish complex months and reward inefficiency. Most modern UK firms (including ours) work on fixed monthly fees based on a service scope agreed up front.

Hourly billing still makes sense for:

For everything else — recurring bookkeeping, VAT, payroll, year-end — insist on a fixed monthly fee. It aligns your incentives (your accountant wants efficiency) and lets you budget.

What should be included in your monthly fee

For a typical UK limited company paying £150–£200/month, the deliverables you should be getting are:

If your current accountant charges similar fees but your software licence is on your credit card, your bookkeeping is “advisory only”, or you need to chase them for the year-end work, you’re paying for less than the market rate suggests you should be getting.

Hidden costs to watch for

Common “extras” that should be included in the headline monthly fee but sometimes aren’t:

How to evaluate value (not just price)

The cheapest accountant is rarely the best value. When comparing quotes, weigh:

  1. Qualification. Are they ACCA, ACA, or CIMA qualified? An unqualified bookkeeper at £40/month may cost you a £2,000 tax mistake.
  2. Communication speed. Ask their average reply time. Anything over 48 hours during business days is a red flag.
  3. Sector experience. An accountant who’s done 50 ecommerce clients knows things one who’s done one will miss.
  4. Software stack. If they’re still on desktop Sage 50, they’re behind. Modern firms work in the cloud.
  5. Tax savings track record. Ask for examples of money saved for similar businesses.

When does an accountant pay for themselves?

For a typical UK limited company, a competent accountant should:

For a £100k turnover limited company, those savings typically run £2,000–£5,000 a year against an accountant fee of £1,200–£3,000. The maths nearly always favours having one.

Frequently asked questions

Are accountant fees tax-deductible?

Yes, for limited companies and sole traders. Accounting fees relating to your business are an allowable expense for both Corporation Tax and Income Tax. The portion relating to a personal Self Assessment isn’t deductible against your business; it’s a personal expense.

Can I change my mind and switch later?

Always. Switching accountants in the UK is straightforward — your new accountant handles most of it via a “professional clearance” process. Read our full guide to switching accountants for the steps.

What if my business is seasonal?

Most fixed-fee firms keep the monthly fee flat year-round, because the workload averages out. Some allow “pause months” for genuinely dormant periods, but it’s worth checking up front.

Should I pay monthly or annually?

Monthly. It spreads cash flow, keeps your accountant accountable to ongoing service, and avoids you locking in an annual fee with a firm you’ve only just met.

Can I do my own accounts and just pay for a year-end review?

For a sole trader with under 100 transactions a year, yes — DIY plus a £200–£400 Self Assessment review can work. For a limited company, almost never. The compliance burden (Companies House, Corporation Tax, payroll, VAT, MTD) is too high to cover with a once-a-year review without something slipping.

The bottom line

For most UK businesses, the right monthly accountant fee in 2026 lives in the £99–£300 range. Lower than that and you’re typically getting compliance-only, no advice. Higher than that and you should be getting genuine finance partnership, not just bookkeeping with a markup.
