If you've never had your books formally reviewed by someone outside your own business, a bookkeeping health check is one of the most useful exercises you can invest in. It's not an audit in the formal sense, but a structured review designed to spot problems, confirm what's working, and give you a clear picture of exactly where your financial records currently stand. Here's what's typically involved when a local accountant carries one out for a London small business, from first look to final report. It's a process worth revisiting periodically too, not just as a one-off exercise, since business circumstances and software requirements tend to change more quickly than most owners expect.
Reviewing How Transactions Are Being Categorised
The first step in most health checks is examining how transactions have been categorised across the business's accounting software. This means checking whether expenses are sitting in sensible, consistent categories, whether capital and revenue items have been correctly distinguished, and whether anything looks obviously misclassified. Getting this right matters because miscategorised transactions distort your profit and loss statement and can even affect your tax position, so it's usually one of the first things a thorough health check examines closely before moving on to other areas.
This kind of review also gives business owners a genuinely useful opportunity to ask questions about their own numbers that they may have been unsure how to raise before, since a health check is specifically structured as a moment for open, detailed discussion rather than a routine compliance task squeezed into a wider meeting agenda.
Checking Bank Reconciliation Accuracy
A health check will always involve verifying that bank accounts have actually been reconciled properly, not just marked as reconciled without genuine checking. This means comparing what the accounting software shows against actual bank statements, looking for unexplained discrepancies, duplicate entries, or transactions that were never matched correctly. Since bank reconciliation is one of the fundamental safeguards in good bookkeeping, gaps here are often a strong early indicator that other areas of the books need closer attention too, and rarely occur in isolation.
Where discrepancies are found, a thorough health check doesn't stop at simply flagging them, it traces each one back to its root cause, whether that's a timing difference, a duplicate entry, or a genuine error, so that the underlying process can be corrected rather than just the individual transaction. This distinction matters considerably, since fixing a symptom without addressing the cause usually means the same issue reappears again within a few months.
Assessing VAT Treatment and Compliance
For VAT-registered businesses, a health check will examine whether VAT has been applied correctly across different types of transaction, whether reclaimable VAT has actually been reclaimed, and whether Making Tax Digital requirements are being properly met. VAT errors are among the costliest bookkeeping mistakes because they carry direct compliance risk with HMRC, so this part of the review tends to be particularly thorough, checking not just current figures but the processes generating them going forward, so the same mistakes aren't repeated quarter after quarter. This is one reason international and multi-channel businesses in particular benefit from having this area reviewed by a specialist familiar with cross-border rules.
Evaluating Software Setup and Automation
A surprising number of bookkeeping issues stem not from human error but from software that was never configured correctly in the first place. A health check looks at how your accounting platform has been set up, whether bank feeds are working properly, whether the chart of accounts makes sense for your business, and whether opportunities for automation are being missed. Fixing setup issues at this stage often prevents a whole category of future errors from ever occurring, making it one of the most valuable parts of the process for any growing business.
We regularly find businesses paying for premium software features they've never actually turned on, while simultaneously missing simpler automations that would save real time every single week. A health check identifies both sides of this equation, ensuring you're getting full value from the tools you're already paying for rather than leaving useful functionality sitting unused indefinitely.
Reviewing Payroll and Statutory Obligations
Where relevant, a bookkeeping health check will also examine payroll records for accuracy and compliance, including pension auto-enrolment obligations, RTI submissions to HMRC, and whether statutory record-keeping requirements are being met consistently. Payroll errors can be particularly costly if left unchecked, so confirming this area is under control gives real peace of mind alongside the more general bookkeeping review, especially for businesses that have recently taken on new staff or changed pay structures.
This is especially relevant for businesses that have grown quickly, since payroll processes set up for two or three staff often don't scale cleanly to a team of ten or more without deliberate review and adjustment. A health check catches this kind of growing pain before it turns into a genuine compliance issue with HMRC or The Pensions Regulator.
What You Receive at the End of a Health Check
A proper health check should conclude with more than a verbal reassurance; you should come away with a clear, practical summary. This typically includes:
- A written summary of issues found, ranked by priority and urgency
- Specific recommendations for correcting errors already identified
- Suggestions for improving software setup or ongoing processes
- A realistic view of whether current bookkeeping arrangements are sufficient
Our bookkeeping and accounting services include health checks designed to give London business owners exactly this kind of clarity and confidence going forward.
How Often a Health Check Is Worth Repeating
A single health check is valuable, but it's not necessarily a once-in-a-lifetime exercise. Businesses going through significant change, taking on new staff, switching software, entering new markets, or simply growing quickly, often benefit from repeating the process every year or two, since the areas most likely to develop problems tend to shift as the business itself evolves. What was working well when a business had three staff and a single sales channel may no longer hold up once headcount doubles or a second trading channel is added, and a periodic health check catches this kind of drift before it becomes deeply embedded in everyday processes.
Many London businesses find it useful to schedule a health check to coincide with a natural milestone, such as the start of a new financial year, a change in software provider, or shortly after a significant change in the business itself. This timing makes the findings immediately actionable, since there's a natural opportunity to implement recommended changes cleanly rather than trying to retrofit them into an already established routine. Treating the health check as a recurring part of good financial housekeeping, rather than a one-off emergency measure, is ultimately what delivers the most lasting value for the business over time.
The Bottom Line
A bookkeeping health check is a relatively small investment that can uncover issues worth far more than its cost to fix, whether that's a VAT reclaim you've been missing or a compliance risk building quietly in the background. For any London business that hasn't had an independent review of its books recently, it's a sensible and reassuring place to start. Many business owners tell us it's the first time they've properly understood the state of their own books, which alone makes the exercise worthwhile.
