Content Verification & Compliance Stamp: This technical accounting guide is written and peer-reviewed by Sukh, Lead Accountant at AccKent. All financial metrics, tax rates, and software procedures are verified against current HMRC 2026/2027 guidelines and official FreeAgent operational updates to ensure total accuracy for UK Limited Companies.
Executive Summary for Business Directors: While holding a commercial current account with Mettle, NatWest, or RBS completely waives FreeAgent’s standard monthly software subscription fees, it does not guarantee corporate tax compliance. Managing a UK limited company involves separate legal liabilities, complex dividend-to-salary structuring, and strict statutory filing deadlines. Professional human accounting oversight ensures that automated Open Banking data is accurately reconciled, protected from HMRC coding mistakes, and optimized to claim all valid corporate tax reliefs under current UK legislation.
If you are a freelancer, contractor, or small business owner looking into business banking, you have almost certainly seen the enticing offer: Get FreeAgent accounting software for FREE when you open a business account with Mettle, NatWest, or Royal Bank of Scotland (RBS).
Given that FreeAgent normally costs up to £35+VAT per month, this sounds like a no-brainer. But in the world of business finance, the word "free" usually comes with a catch.
So, is FreeAgent really free? And more importantly, does getting free software mean you no longer need the help of professional FreeAgent accountants?
Let’s break down exactly how this offer works, what you get, and what you still need to watch out for.
How Do the Free NatWest, RBS, and Mettle FreeAgent Software Offerings Work?
The short answer to the question is: Yes, the software itself is completely free. If you hold a business bank account with NatWest, Royal Bank of Scotland, or Ulster Bank NI, or if you use the digital banking app Mettle, you get full access to FreeAgent’s award-winning accounting software without paying the monthly subscription fee.
You get all the premium features, including:
Automated bank feeds (your transactions sync automatically)
Invoicing and expense tracking
Self-Assessment and VAT return generation
Dividend tracking
As long as you retain your eligible bank account, you won't pay a penny for the software. So, where is the catch?
How to Link Your Mettle Bank Account to FreeAgent in 3 Steps
Open your Mettle App: Navigate to the 'Connections' or 'Settings' tab inside your active Mettle account.
Select FreeAgent: Click on the FreeAgent integration option and log in using your active AccKent client credentials.
Approve Bank Feed Shares: Share your real-time transaction data stream. Once approved, FreeAgent will instantly waive your software subscription fee, and our accounting team at AccKent will begin managing your live bookkeeping ledger.
Can a Limited Company Director Maintain HMRC Compliance Using FreeAgent Software Alone?
The catch isn't in the pricing—it's in the execution. FreeAgent is brilliant software, but it is just a tool. It calculates based on the data you put into it.
Many business owners fall into the trap of thinking, "I have free software that calculates my tax; therefore, I don't need an accountant." This is a costly mistake. If you categorise an expense incorrectly, claim VAT on something you shouldn't, or miss out on tax-deductible allowances because the software didn't prompt you, HMRC will still hold you responsible.
This is exactly why partnering with specialist FreeAgent accountants is the best way to maximize this banking offer.
Why Should UK Small Businesses Pair a Free Mettle Account with a Certified Accountant?
Getting the software for free is a fantastic operational saving, but without a dedicated accountant, you are leaving money on the table. Here is why the most successful businesses pair their free Mettle/NatWest account with expert FreeAgent accountants:
1. Tax Efficiency & Planning
FreeAgent will tell you what your tax bill currently is, but it won’t tell you how to legally reduce it. An expert accountant will look at your FreeAgent dashboard and advise you on the most tax-efficient way to pay yourself (salary vs. dividends), claim obscure expenses, and plan for corporation tax. At AccKent, we help you maximize this banking loop by layering professional Chartered tax oversight over your free software framework from just £47.50 per month.
2. Catching Costly Errors
Automated bank feeds are great, but software can miscategorise transactions. If FreeAgent accidentally classes a standard expense as an asset, your tax calculations will be completely wrong. As certified FreeAgent accountants; we regularly audit your software to ensure every single entry is perfectly compliant with HMRC rules.
3. Avoiding HMRC Penalties
Making Tax Digital (MTD) means HMRC expects your digital records to be flawless. Submitting incorrect data—even accidentally—can trigger stressful investigations and hefty fines. We act as your safety net, reviewing your data before hitting "submit" to HMRC.
4. Translating Data into Business Growth
FreeAgent generates beautiful cash flow charts, but what do they actually mean for your business? We take your FreeAgent data and provide real-world business advisory services. We help you understand if you can afford to hire a new employee, invest in new equipment, or expand your operations.

1. Zero Software Overhead: You leverage your corporate banking integration to completely eliminate your monthly software platform licensing costs.

Conclusion: Don't Rely on Software Alone
Is FreeAgent free with a Mettle, NatWest, or RBS account? Yes. Is it a substitute for a qualified accountant? Absolutely not.
Think of FreeAgent like a high-performance sports car. The bank has just handed you the keys for free, but you still need a professional driver to help you win the race.
Even with a free Mettle account, you still need to ensure your tax returns are correct. This is why many directors use FreeAgent accountants for limited company management to handle the final submissions.
If you are behind on your filings, we offer a dedicated one-off year-end accounts rescue service to get your company compliant.
Ready to get the most out of your software? If you are already using FreeAgent (or are about to sign up via your bank) and want to ensure your business is as tax-efficient as possible, get in touch with the team at AccKent today.

Frequently Asked Questions About FreeAgent, Mettle, and NatWest Banking
Is FreeAgent genuinely free for business account holders with Mettle, NatWest, or RBS?
Yes, absolutely. The standard FreeAgent software subscription fee is completely subsidized and waived for UK limited companies, freelancers, and contractors who maintain an active business current account with Mettle, NatWest, or the Royal Bank of Scotland (RBS). There are no hidden software platform fees passed onto you, making it an excellent operational cost saving for your business.
Can I submit my company's CT600 Corporation Tax return via FreeAgent without an accountant?
While FreeAgent features automated internal mechanisms capable of generating and filing year-end figures under the FRS 105 Micro-Entities framework, doing so without a certified professional introduces significant risks. The software cannot catch bank reconciliation errors, optimize your personal director salary-to-dividend tax splits, or manually claim advanced capital allowances. Relying purely on a DIY approach leaves you completely exposed to automated HMRC validation flags and penalties.
If I link my free bank tariff to a FreeAgent accountant, can they see my actual bank account?
No. When you grant us accountant permission via your FreeAgent dashboard, we only gain secure visibility over the financial transaction ledger data flowing through the read-only Open Banking data stream. We never have access to your live online banking apps, your secure login credentials, or the operational capability to authorize payments or withdraw funds from your company account.
Do I need to visit your office in Dartford to link my Mettle or NatWest account?
Not at all. While AccKent Accountants is anchored locally in Dartford, Kent (conveniently off Junction 1b of the M25 near the Dartford Crossing and Bluewater), our practice operates a remote-first cloud model. We handle your identity verification checks, professional clearance handovers from your previous provider, and HMRC agent authorizations completely online, securely connecting limited company directors across London, Kent, and nationwide throughout the UK.
