How Much Does an Accountant Cost in London in 2026?
A freelance designer in Croydon might only need help with one Self Assessment return each year. A growing café in Central London may need weekly bookkeeping, payroll, VAT returns and someone to answer questions when cash flow gets tight. Both need an accountant, but their fees will be completely different. That is why one London business owner may receive a quote for £100 a month, while another is quoted £400 or more.

Others manage your books throughout the year, run payroll, submit VAT returns, monitor tax deadlines and help you make better financial decisions before problems arise.
