The 10 Best Accountants in London (2026)

Updated October 2026 · 10 picks

The best accounting firms in London in 2026 include Saffery for private clients and family businesses, Blick Rothenberg for international individuals and companies setting up in the UK, HaysMac and Buzzacott for charities and owner-managed businesses, and BDO and Grant Thornton for growing mid-sized companies. Deloitte and PwC are the Big Four choices for large businesses.

Anyone can call themselves an accountant in the UK; 'chartered accountant' and registered auditor are the protected titles to look for. For an individual with a tax return, a mid-sized or specialist firm is usually a better fit than the Big Four. Americans should also see our guide to US tax accountants in London.

Frequently asked questions

How much does an accountant cost in London?

For a straightforward personal Self Assessment tax return, small London practices often charge from a few hundred pounds; specialist and mid-sized firms charge more, and complex returns with foreign income, trusts or property portfolios can run into the thousands. Company accounts, payroll and VAT are usually priced as an annual fixed fee. Ask for a written fee estimate and what is excluded.

When is the Self Assessment deadline?

For most people, online Self Assessment returns and any tax owed are due by 31 January after the end of the tax year, which runs from 6 April to 5 April. Paper returns are due by 31 October. Late filing triggers an automatic penalty, so if you are new to the UK and think you need to file, register with HMRC well before the deadline.

What is Making Tax Digital for Income Tax?

From April 2026, self-employed people and landlords in England, Wales, Scotland and Northern Ireland with qualifying income over £50,000 must keep digital records and send HMRC quarterly updates using compatible software, with the threshold due to fall to £30,000 from April 2027. Most accountants now offer a package to handle this.

I have moved to London from abroad. What should I ask an accountant?

Ask about your UK tax residence status (the Statutory Residence Test), how your overseas income and gains are taxed, and any split-year treatment in your arrival year. The old 'non-dom' remittance basis was abolished from 6 April 2025 and replaced by a residence-based regime that gives some new arrivals relief on foreign income and gains for their first four years. Rules are detailed, so choose a firm that does international private-client work, such as Blick Rothenberg, Saffery or the Big Four.

How do I check an accountant is qualified?

Ask which professional body they belong to and look them up: the ICAEW, ACCA, ICAS and CIOT all run public member directories. Members of these bodies must hold professional indemnity insurance and follow a code of ethics. If you need an audit, check the firm is on the Register of Statutory Auditors.
