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.

How We Help Small Businesses Save Time and Stay Compliant
Financial administration can quickly take time away from sales, customers and business development. Our role is to manage the accounting work accurately while giving you useful financial information when you need it.
Keep Your Records Organised
We help maintain accurate records of income, expenses, invoices and other transactions. Better records make tax preparation easier and reduce the risk of missing important information.
Stay Ahead of HMRC Deadlines
We help manage relevant filing requirements for Self Assessment, Corporation Tax, VAT, payroll and company accounts. This reduces the risk of overlooked deadlines and avoidable compliance problems.
Understand Your Tax Position
Your tax liability should not come as a surprise at the end of the year. We can review your figures and explain upcoming liabilities so you can plan your cash flow accordingly.
Make Better Business Decisions
Accurate financial information helps you understand whether revenue is increasing, costs are under control and the business is generating sustainable profits. This gives you a stronger basis for decisions about hiring, investment and expansion.
Improve Cash-Flow Visibility
Profit and cash are not the same. We can help you understand expected income, upcoming costs and tax liabilities so you can plan your available cash more effectively.
Prepare for Business Growth
When your business expands, accounting requirements often become more complex. We can support changes such as VAT registration, new employees, increased reporting requirements and wider tax planning.

Faqs about Small Business Accountants in London
What does a small business accountant in London do?
A small business accountant manages all aspects of your business finances from bookkeeping and VAT returns to year-end statutory accounts, Corporation Tax, payroll, and HMRC compliance. At AccFirm, we go beyond basic compliance by providing proactive tax planning, cash flow management, and strategic financial advice throughout the year, helping you make informed decisions and reduce your overall tax liability.
How much does a small business accountant cost in London?
The cost of a small business accountant in London varies depending on your business structure and the services required. As a guide, sole traders typically pay between £50 and £150 per month for a full-service accountant covering bookkeeping, VAT, and Self-Assessment. Limited companies with employees typically pay between £100 and £350 per month. AccFirm charges fixed monthly fees with everything included no hourly rates, no call charges, and no hidden costs. Contact us for a free, tailored quote.
Do I need an accountant as a small business owner in London?
While it is not a legal requirement, the vast majority of small business owners benefit significantly from working with a professional accountant. An accountant ensures you never miss an HMRC deadline, claims every allowable expense you are entitled to, reduces your Corporation Tax and Self-Assessment liabilities, and frees up your time to focus on running and growing your business. For most small businesses, an accountant saves more in reduced tax than the monthly fee costs.
What is Making Tax Digital and how does it affect my small business?
Making Tax Digital (MTD) is HMRC’s programme requiring businesses to maintain digital financial records and submit returns using HMRC-approved software. MTD for VAT is already mandatory for all VAT-registered businesses. From April 2026, MTD for Income Tax Self Assessment (MTD for ITSA) will apply to sole traders and landlords with income above £50,000, with the £30,000 threshold following in April 2027. AccFirm ensures every client is fully MTD-compliant using Xero, QuickBooks, or FreeAgent included in your monthly package at no additional cost.
Can AccFirm help my small business reduce its tax bill legally?
Yes. AccFirm uses fully legitimate HMRC-approved tax planning strategies to ensure every client pays only the minimum tax required by law. For limited companies this includes optimising your director salary and dividend structure, identifying R&D Tax Credits, maximising Annual Investment Allowance on capital expenditure, and planning capital gains tax efficiently. For sole traders we ensure every allowable expense is claimed and advise on pension contributions as a tax-efficient strategy.
How quickly can I switch from my current accountant to AccFirm?
Switching to AccFirm is completely straightforward. We manage the entire process contacting your previous accountant, obtaining all handover documents and records, completing HMRC agent authorisation, and migrating your accounting software data. Most clients are fully set up and operational within five working days. There is no disruption to your business during the transition.
Do I need to visit an AccFirm office, or can everything be done online?
AccFirm works with clients both in person and fully remotely. Our London office is available for face-to-face meetings, but the majority of our services are delivered digitally through cloud accounting software, secure client portals, email, and video calls. Many of our small business clients across London and the wider UK have never visited our office and they receive exactly the same level of service and support.
Does AccFirm work with small businesses in all industries?
AccFirm works with small businesses across a wide range of industries including retail, hospitality, construction and CIS, professional services, creative and media, e-commerce, technology, healthcare, property and landlord investment, and many more. Our team has experience across multiple sectors and can provide industry-relevant advice on expenses, tax reliefs, and HMRC compliance specific to your business type.
