How Much Does an Accountant Cost in the UK? (2025/26 Fees Guide)

“How much does an accountant cost?” is one of the most sensible questions a business owner can ask — and one of the hardest to get a straight answer to. Here’s a clear, honest guide to what you can expect to pay in the UK, and what drives the price. For costs specific to your situation, you can also jump to our dedicated guides for sole traders, limited companies and small businesses.

The short answer

Accountancy fees vary a lot, because businesses vary a lot. But as a rough guide for 2025/26:

These are ballpark figures — your actual cost depends on the factors below. (Our own pricing is set out plainly in fixed monthly plans.)

Fixed fee vs hourly

The biggest shift in recent years is away from hourly billing. Most modern, especially online, accountants now charge a fixed monthly fee that bundles your bookkeeping, returns and ongoing support into one predictable price.

This is almost always better for you than hourly billing, because:

• You know the cost up front — no nasty year-end invoice
• You’re not charged for asking a question
• The cost spreads across the year

If an accountant still quotes purely by the hour, ask for a fixed quote instead.

What drives the price

Two businesses with the same turnover can pay very different fees, depending on:

• Structure — a limited company (statutory accounts, Corporation Tax, confirmation statement, payroll) costs more to run than a sole trader’s single Self Assessment
• Transaction volume — more invoices and expenses = more bookkeeping
• VAT registration — quarterly VAT returns add work
• Payroll — more employees, more cost
• How tidy your records are — clean cloud bookkeeping is far cheaper to work with than a shoebox of receipts
• The level of support you want — year-end only, or a proactive accountant all year

That last-but-one point is worth dwelling on: good records keep your fee down. The messier the inputs, the more you pay.

Is an accountant worth it?

For most businesses, a good accountant pays for themselves — and then some — by:

• Claiming every allowable expense and relief, so you don’t overpay tax
• Keeping you off penalties by filing on time
• Handing back the hours you’d spend on admin
• Giving you advice that saves money (the right structure, pay mix, VAT scheme)

The honest exception: if your affairs are genuinely tiny and simple — a small side income with few expenses — you may be fine doing it yourself, and a decent accountant will tell you so rather than sell you something you don’t need.

How to compare quotes fairly

When you’re weighing up accountants, look past the headline number:

• What’s actually included? Bookkeeping? VAT? Payroll? Support? A cheap quote that excludes half the work isn’t cheap.
• Fixed or hourly? A fixed fee is easier to budget and usually better value.
• One-off or ongoing? A year-end-only fee buys you less than monthly support.
• Tie-ins? Look for rolling terms, not long lock-ins.
