How Much Does an Accountant Cost in London? A 2025/26 Pricing Guide

Why Accountant Fees Vary So Much in London

If you have searched for an accountant in London, you will have noticed that fees can range from a few hundred pounds to several thousand per year. This variation is not random — it reflects differences in the scope of services, the experience and qualifications of the accountant, the complexity of your affairs, and the location of the practice. A sole practitioner working from a home office in Zone 5 will charge very differently from a mid-tier firm with offices in the City. Understanding what drives these costs will help you compare quotes fairly and avoid nasty surprises.

Self Assessment Tax Returns

For straightforward Self Assessment tax returns — typically for employees with a single source of income, or sole traders with simple accounts — London accountants generally charge between £250 and £500 + VAT. If you are a sole trader with turnover above £85,000, have rental income, foreign income, capital gains, or other complexities, expect to pay between £400 and £800 + VAT. At the top end, individuals with multiple income sources, overseas assets, or complex tax planning requirements may pay £1,000 or more. Filing your return yourself through HMRC's online portal is free, but the risk of missing legitimate deductions or making errors that trigger penalties often makes professional help worthwhile.

Limited Company Annual Accounts and Corporation Tax

For a small limited company with straightforward affairs (a single director-shareholder, modest turnover, and no complex transactions), you can expect to pay between £800 and £1,500 + VAT per year for the preparation and filing of statutory accounts with Companies House and a Corporation Tax return (CT600) with HMRC. This typically includes the confirmation statement filing as well. Medium-sized companies with higher turnover, multiple directors, or more complex accounting requirements will usually pay between £1,500 and £3,500 + VAT. These figures are for the annual compliance work only — they may not include day-to-day bookkeeping, payroll, or VAT returns, which are often priced separately.

Bookkeeping Services

Monthly bookkeeping is one of the most variable costs because it depends heavily on the volume of transactions your business processes. For a small business with fewer than 50 transactions per month, expect to pay between £100 and £250 + VAT per month. For businesses with 50 to 200 transactions, fees typically range from £250 to £500 + VAT per month. Larger or more complex businesses with high transaction volumes, multiple bank accounts, or foreign currency transactions will pay more. Many accountants now offer bookkeeping through cloud accounting platforms like Xero or QuickBooks, which can reduce costs by automating bank feeds and receipt capture.

Payroll Services

If you employ staff, you will need a payroll service to handle RTI submissions to HMRC, payslips, and year-end reporting. For a company with 1 to 5 employees, monthly payroll processing typically costs between £50 and £150 + VAT per month. For 5 to 20 employees, expect £100 to £300 + VAT per month. These fees usually include the processing of starters and leavers, statutory sick pay and maternity pay calculations, and the annual P11D filing. Auto-enrolment pension administration may be an additional cost of £30 to £100 per month depending on the number of employees.

VAT Returns and VAT Services

Quarterly VAT return preparation and filing typically costs between £150 and £350 + VAT per quarter for a straightforward business. If your business has partial exemption, deals with international trade, or operates under a special VAT scheme (flat rate, margin scheme, etc.), fees will be higher. Annual VAT compliance therefore adds roughly £600 to £1,400 to your total accounting costs. Businesses approaching the VAT threshold should also budget for initial registration and setup costs, which are usually a one-off fee of £150 to £300.

Fixed Fees vs Hourly Rates

Most London accountants for small businesses now offer fixed-fee packages rather than billing by the hour. This is a positive development for clients because you know exactly what you will pay each month or year, with no surprises. Fixed-fee packages typically bundle together the services you need — for example, annual accounts, Corporation Tax return, personal tax return, payroll, and VAT returns — into a single monthly or quarterly fee. For a typical one-director limited company with payroll and quarterly VAT, an all-inclusive fixed-fee package in London usually ranges from £200 to £400 + VAT per month (£2,400 to £4,800 per year).

Hourly rates, where they are still used, range from £75 to £150 per hour for junior staff and £150 to £350 per hour for partners or directors at the firm. Ad-hoc advisory work, tax investigations, and complex restructuring are more commonly billed by the hour.

What Affects the Price?

Several factors influence how much your accountant will charge:

• Quality of your records: If you hand over a shoebox of receipts, expect to pay significantly more than if you maintain clean, up-to-date records in accounting software.
• Business complexity: Multiple income streams, international transactions, group structures, and large numbers of employees all increase costs.
• Turnaround time: Leaving everything to the last minute and expecting a rush job will often attract premium fees.
• Qualifications: Chartered accountants (ACA, ACCA, CIMA) typically charge more than unqualified bookkeepers, but they bring deeper expertise and professional accountability.
• Location: Central London firms have higher overheads, which is reflected in their fees. However, many firms now work remotely, so you are not limited to accountants in your immediate area.

How to Get Value for Money

The cheapest accountant is rarely the best value. An experienced accountant who charges more but saves you thousands in tax, keeps you compliant, and provides proactive advice is far better value than a cut-price service that simply files your returns. When comparing quotes, make sure you are comparing like with like — check exactly what is included, ask about additional charges for ad-hoc queries, and find out whether the fee includes tax planning advice or just compliance work.
