Cheap Online Accountant in London
Finding a cheap accountant in London does not mean settling for less. It means finding an accounting firm that has eliminated the overhead of expensive high-street offices, the inefficiency of paper-based systems, and the billing model that charges you every time you pick up the phone and pass those savings directly on to you. At AccFirm, we provide fully qualified, professional online accounting services for London businesses at a fraction of what traditional high-street accountants charge with no hidden fees, no hourly billing, and no compromise on the quality of advice or service you receive.
Our clients are sole traders, freelancers, limited companies, contractors, self-employed professionals, and small businesses across London all of whom have made the switch from expensive traditional accountants or generalist online services to AccFirm dedicated, affordable online accounting. They pay less. They get more. And they have a named, qualified accountant who knows their business, responds the same day, and proactively manages every HMRC deadline throughout the year.
AccFirm is not a budget directory service or an automated platform with minimal human support. We are a regulated, qualified London accounting firm holding ACA, ACCA, ATT, and AAT qualifications that has chosen to operate online, eliminating the costs that traditional firms pass on to clients. The result: professional, comprehensive accounting at genuinely affordable fixed monthly fees that are transparent from day one.

Sarah Thompson
Thompson Retail Ltd
As a contractor under the Construction Industry Scheme (CIS), I needed accountants who truly understand HMRC requirements. They managed my CIS registration, monthly returns, and self-assessment without any stress. Their guidance saved me both time and money. Professional, reliable, and always available when needed
James Patel
Self-Employed Contractor (CIS)
AccFirm took over our accounts when our previous firm kept missing deadlines. Within three months they had identified over £4,200 in tax savings we had been leaving on the table including expenses we had never been told we could claim. They handle everything from our quarterly VAT returns to our year-end accounts and payroll, and our dedicated accountant is always reachable. For any London small business owner, I cannot recommend them enough.

Why London Businesses Switch to AccFirm for Affordable Accounting?
The London accounting market has long been dominated by two extremes: expensive high-street firms charging £150–£350 per month for services that rarely justify the premium, and ultra-cheap automated platforms offering minimal human support at £10–£30 per month. AccFirm occupies the space that most London businesses actually need genuinely qualified, professionally managed accounting at a transparent, affordable fixed fee that includes everything, not just the basics.
The comparison table above illustrates the typical cost difference. For a sole trader in London paying £150 per month to a high-street accountant, switching to AccFirm at £85 per month saves approximately £780 per year while receiving exactly the same services, plus a more responsive dedicated accountant and full cloud accounting software included at no extra cost.
The reason AccFirm can deliver this pricing is straightforward: we operate online, we use cloud accounting software to eliminate administrative overhead, and we do not have the costs of premium City office space or paper-based processes. Every efficiency we create translates directly into a lower fee for you not a higher profit margin for us.

Is AccFirm Actually Cheap Or Just Good Value?
The word ‘cheap’ in accounting carries a risk of misinterpretation. When people search for a cheap accountant in London, they are almost never looking for poor advice; they are looking for professional accounting services at a price that reflects what online, cloud-based accounting actually costs, rather than what an expensive high-street office used to charge.
AccFirm fees are transparent, fixed, and all-inclusive. As the table above shows, the services included in an AccFirm package dedicated accountant, all HMRC filings, cloud accounting software, unlimited queries, MTD compliance are frequently charged as expensive extras by traditional firms. The true comparison is not AccFirm fee vs a competitor’s headline monthly rate, it is AccFirm all-in fee vs the competitor’s headline rate plus all the extras that appear throughout the year.
Our team holds ACA, ACCA, ATT, and AAT qualifications from the UK’s leading professional accounting bodies. We are registered with HMRC as authorised agents for all our clients. Every service we provide is covered by professional indemnity insurance, and our practice is fully regulated. Affordable pricing does not mean unqualified advice at AccFirm it means qualified advice delivered efficiently.
