How much does an accountant cost in the UK?

It depends.

According to Taxley, the average cost of a Year End Accounts and CT600 meant to be costing between £300 and £595 a year to a limited company.

Accountant cost is shaped by your turnover, how many transactions you process, whether you're VAT-registered, and whether you need payroll handled too. No two businesses pay exactly the same, which is why vague "from" prices can be frustrating.

That's why Debitam keeps things simple with one fixed fee: £399 + VAT a year for company accounts and your tax return. No creeping hourly rates, no guesswork about your final bill.

How much do accountants charge for limited companies UK?

Limited company accountant fees typically cover your statutory accounts and your CT600 corporation tax return, the two filings every company must submit.

Debitam's fixed £399 + VAT covers both, with a dedicated accountant assigned to your case from day one. It is perfect for you if you don't want to speak to a bot but to a real UK-qualified accountant.

Here's why business owners choose this over shopping around:

What makes an accountant charge more?

Several factors can push your accountant's fees up:

• Higher turnover: more income usually means more to review and report.
• More transactions: every extra invoice, receipt, and payment takes time to process.
• VAT registration: regular returns add ongoing work.
• Payroll: staff or director payroll adds another layer of admin.
• Messy books: records that need untangling before anything can be filed.
• HMRC Enquiries: Expert support to guide you through appeals and ensure compliance while protecting your business.
• R&D tax claims: Claiming innovation credits means your accountant has to review project costs, staff time, and technical evidence, then write up a detailed report for HMRC. That extra specialist work is why fees go up.

Late or disorganised records are the biggest culprit. They mean extra work for your accountant, and extra cost for you.

Want to keep fees down? Keep your records clean and up to date throughout the year. It's the simplest way to save money, whoever you work with.

How much does filing yourself with software cost instead?

Filing your own accounts with software can look cheaper on paper. But you're still responsible for getting the figures right, formatting them correctly for iXBRL submission, and dealing with HMRC directly if something's queried. There's no one checking your work, and no one to call when a deadline sneaks up on you.

Recent data from Business in the News reveals that UK businesses collectively lose an estimated £25 million annually attempting to handle their own accounts and tax returns.

The StartUp Magazine's survey in July 2026 found UK businesses lose an average of 11 hours a week on accounting tasks like admin, bookkeeping and tax returns.

Accountant vs. accounting software

Key Takeaway: Accountants provide tailored, expert support at a higher upfront cost, ideal for businesses with complex financial needs or limited time. Accounting software offers cost-effective automation for straightforward tasks but requires users to stay on top of tax laws, audits, and manual inputs.
