How to Choose the Right Accountant in London
09/07/2025
Reading Time:
Choosing the right accountant in London isn’t just about staying compliant with HMRC — it’s a strategic move that can shape the future of your business. In a city where regulation, competition, and opportunity go hand in hand, your accountant should be more than just a service provider. They should be a financial partner who understands your goals, saves you time, and helps your business thrive.
Whether you’re a freelancer streamlining expenses, a landlord preparing for Making Tax Digital, or a small company growing fast, this guide walks you through everything you need to look for in a London-based accountant.
Choose a qualified, chartered accountant
The first step in choosing the right accountant is checking their credentials. A Chartered Accountant is regulated, insured, and professionally trained to the highest UK standards. Non-Chartered or unregulated advisors may lack proper insurance, be harder to hold accountable for errors, and may not follow CPD (continuing professional development) — meaning their tax knowledge could be outdated.
| Qualification | Stands For | Why It Matters |
|---|---|---|
 | Institute of Chartered Accountants in England & Wales | Prestigious, audit-ready, and often advisory-focused |
 | Association of Accounting Technicians | Great for bookkeeping, but limited for full tax strategy |
 | Association of Chartered Certified Accountants | Globally recognised; strong for SMEs, startups, and international business |
💬 Always confirm who will be managing your account — is it a qualified accountant or a support-level team member?
Choose an accountant who understand your type of business
Different businesses have different tax rules, reporting obligations, and opportunities. That’s why your accountant should understand your income structure, sector-specific reliefs, and risk areas. A generalist might get the job done, but a specialist will spot tax-saving opportunities, reduce risk, and give you relevant advice all year round.
| Business Type | What to Look For |
|---|---|
| Freelancers & Contractors | IR35 planning, BR/K code accuracy, efficient expense setup |
| Startups & Limited Companies | Company formation, R&D claims, director salary/dividend strategies |
| Landlords & Property Businesses | MTD for ITSA, CGT planning, mortgage interest relief, rent structuring |
💬 Ask:
“Can you give an example of how you’ve helped a client like me save time or money?”
Make sure they’re cloud-first and MTD-compliant
The right accountant should make your finances easier to manage — not more complicated. In 2025, that means they must support:
- Cloud accounting (Xero, QuickBooks, FreeAgent)
- Digital receipt capture (Dext, Hubdoc)
- Making Tax Digital (for VAT and soon Self Assessment)
From April 2026, MTD becomes mandatory for landlords and more sole traders. Your accountant should already be guiding you toward full compliance. Cloud tools don’t just help with HMRC rules — they also give you real-time financial insights, automate bank feeds, and allow instant collaboration with your accountant. That means fewer surprises, better budgeting, and less admin time.

Expect dedicated, proactive support
A great accountant doesn’t just react — they reach out before issues arise.
You should get:
- A dedicated accountant, not a rotating team
- Advice throughout the year, not just at year-end
- Alerts about tax code errors, deadlines, or new opportunities
A proactive accountant can prevent costly mistakes and save you money. And if your accountant is London-based, they’ll also be more familiar with local tax reliefs, council business rates, and industry-specific regulations that can impact your bottom line.

Understand their fees — and what’s included
Cheap doesn’t always mean value. Before signing up, get a breakdown of:
- Fee structure (fixed monthly, hourly, or project-based)
- What’s included (e.g. bookkeeping, VAT, payroll, Self Assessment)
- Any extra charges (e.g. for landlords with multiple properties)
| Question | Why It Matters |
|---|---|
| Is your fee fixed or hourly? | Helps you plan your budget |
| What’s included in the package? | Ensures no missing essentials |
| Are there extra fees for SA, rental income, or MTD setup? | Avoids surprise bills |
| Will pricing scale fairly if I grow? | Ensures flexibility and fairness |
💬 Tip: Be cautious of ultra-low monthly quotes — they often exclude essential services or limit support.
Check reviews, transparency & real results
A reliable firm will have visible, consistent client feedback. Look for:
- Google or Trustpilot reviews (4.5★ or above)
- Testimonials from clients similar to your business
- Clear examples of how they’ve helped others
Look for reviews that mention responsiveness, clarity, tax-saving insights, and how the accountant helped navigate complex issues (like VAT, payroll, or Self Assessment).
Final checklist: questions to ask before you choose
| Ask This | Why It’s Crucial |
|---|---|
| Are you a Chartered firm (ICAEW/ACCA)? | Ensures quality, regulation, and accountability |
| Do you specialise in my type of business? | Makes your setup faster and more accurate |
| Will I get a dedicated accountant? | Builds trust and long-term understanding |
| Are you MTD-compliant and cloud-ready? | Ensures you stay legal and efficient |
| What’s included in your fee? | Avoids misunderstandings or costly surprises later |
Frequently asked questions
Do I need a Chartered Accountant?
Yes — especially for limited companies, landlords, or anyone needing strategic tax advice. It ensures you get regulated, professional guidance.
What’s the biggest mistake people make when choosing an accountant?
Choosing purely based on cost. Low-cost providers may lack experience, miss key deadlines, or charge extra for critical services.
Do landlords need to prepare for MTD?
Yes — from April 2026, landlords earning over £50K must use MTD-compliant software. A modern accountant should already be preparing you for this.
Is it okay to use a remote firm instead of a London-based one?
You can — but local firms understand London-specific taxes, grants, property rules, and industries better. They’re also familiar with council tax zones, planning restrictions, and localised HMRC practices — and are available for in-person meetings if needed.
