Expert accounting for London small businesses

Whether you are a sole trader, a limited company, or a growing SME, having a qualified accountant on your side makes a measurable difference. We go beyond compliance to give you strategic financial insight that helps your business thrive.

Small business accounting is about much more than filing returns. A good accountant keeps your records accurate, ensures you pay the right amount of tax (not a penny more), and flags opportunities for your business to grow. At GM Professional Accountants, we treat your business as if it were our own.

The profit and loss account, balance sheet, and cash flow statement tell the story of your business. We make sure that story is accurate, timely, and useful for the decisions you make every day.

We work with small business owners across East London, the City of London, Canary Wharf, Stratford, Hackney, Ilford, and throughout Essex. Whether you prefer face-to-face meetings or fully remote support, we adapt to how your business works.

🔐 Sole trader vs limited company

Not sure which structure is right for your business? Many London small businesses save significant tax by switching to a limited company. We assess your situation and advise on the most tax-efficient structure for your circumstances.

Stay ahead of Making Tax Digital

HMRC’s Making Tax Digital programme requires businesses to keep digital records and submit returns using approved software. MTD for VAT is already mandatory. MTD for Income Tax is expanding in 2026 and beyond. Missing deadlines can result in automatic penalties.

All our small business accounting packages include full MTD compliance support. We set up your Xero or QuickBooks account correctly, migrate your existing records, and submit all returns on your behalf so you are always compliant and never at risk of an HMRC penalty.

Frequently asked questions

Everything London small business owners ask us before getting started.

How much does a small business accountant cost in London?
The cost depends on the size of your business, your turnover, and the services you need. At GM Professional Accountants we offer transparent fixed monthly fees so you always know what you are paying with no hidden charges or surprise bills. Get in touch and we will provide a personalised quote for your business promptly.
Do I need an accountant for my small business in London?
While it is not a legal requirement for sole traders, having a qualified accountant typically saves London small businesses significantly more than the cost of the service. Through tax savings, reduced compliance risk, and strategic financial advice, our clients often find that professional accounting support more than pays for itself and frees up significant time every month.
What is the difference between a bookkeeper and an accountant for a small business?
A bookkeeper records day-to-day financial transactions such as invoices and expenses. A qualified accountant goes further by interpreting that financial data, filing tax returns, advising on tax planning strategies, and helping you make strategic business decisions. At GM Professional Accountants our team handles both bookkeeping and full accountancy services within a single fixed monthly fee.
Can a small business accountant help with Making Tax Digital?
Yes. All our small business accounting packages include Making Tax Digital compliance support as standard. We ensure your records are kept digitally using HMRC-approved software such as Xero and QuickBooks, and we submit all returns on your behalf so you stay on top of every deadline.
What qualifications should a small business accountant have?
Look for accountants who hold qualifications from recognised professional bodies such as ICAEW (Institute of Chartered Accountants in England and Wales), CIMA (Chartered Institute of Management Accountants), or AAT (Association of Accounting Technicians). Our accountants at GM Professional Accountants are fully qualified, regulated, and members of recognised professional bodies.
How do I switch to a new accountant for my London business?
Switching accountants is much more straightforward than most people expect. Once you instruct us, we contact your previous accountant on your behalf to request all relevant records and handover information. The process causes no disruption to your business. Get in touch and we will walk you through every step of the switch.
Do you offer a fixed monthly fee for small business accounting?
Yes. All our small business accounting packages are priced on a fixed monthly fee basis with no hourly rates and no surprise charges. You agree the scope of service and the monthly fee upfront, and your fee stays the same. Call us on 0208 396 6128 or get in touch to receive a bespoke quote for your business.
Which accounting software do you support?
We are certified Xero and QuickBooks partners. We can set up, migrate, or continue managing your accounts on either platform. We also support Sage, FreeAgent, and other HMRC-approved cloud accounting software. If you are currently using spreadsheets or a system that is not MTD-compliant, we will help you migrate as part of the onboarding process.
