Solvency in the UK: How to Check It and Directors’ Legal Duties

Keeping your business afloat isn’t just about making sales and paying bills on time. In the background, there’s a legal concept that can quickly become a very practical (and urgent) issue: solvency.

If your business is solvent, you can generally pay your debts as they fall due and your finances stack up on paper. If it isn’t, the decisions you make as a director (or as someone making director-level calls) can carry real legal risk.

You don’t need to be an accountant or an insolvency practitioner to take sensible steps. But you do need to understand what solvency means, how to check it realistically, and what directors’ legal duties look like when there are warning signs.

Important: This guide is general information only and isn’t legal, accounting, insolvency or tax advice. If you’re concerned about your company’s position, get advice on your specific circumstances.

In this guide, we’ll break down solvency in plain English, explain common solvency tests used in the UK, and walk through what directors should do if insolvency might be on the horizon.

What Does Solvency Mean For A UK Business?

In simple terms, solvency is your business’s ability to meet its financial obligations.

For most UK small businesses, solvency comes down to two big questions:

• Can we pay our debts when they’re due? (cash flow reality)
• Do we have enough assets to cover our liabilities? (balance sheet position)

A company can look “successful” on the surface and still struggle with solvency. For example, you might have strong sales but long payment terms, big VAT bills, loan repayments, or supplier invoices landing before your cash arrives.

It’s also worth saying upfront: solvency isn’t just an accounting concept. It’s a legal concept too, and it affects what directors are expected to do (and what they should avoid doing) when finances are tight.

Solvency vs Profit: Why They’re Not The Same Thing

Profit and solvency often move together, but they’re not the same.

• You can be profitable but still insolvent if cash is tied up in unpaid invoices, stock, or long-term projects.
• You can be solvent but unprofitable for a period if you have cash reserves or funding and can still pay bills on time.

When you’re assessing solvency, you’re focusing on your ability to pay what you owe - not just whether you made a profit last quarter.

Why Solvency Matters (And When It Becomes A Legal Issue)

Solvency matters because it sits at the crossroads of smart business management and directors’ legal responsibilities.

When your company is comfortably solvent, directors generally make decisions to promote the success of the company for shareholders (under the Companies Act 2006). But if the company is insolvent (or verging on insolvency), or if an insolvent liquidation or administration becomes probable, directors must consider creditors’ interests - and, in practice, those interests can become increasingly important as the financial position worsens.

That’s where many small businesses get caught out. It’s not always obvious when “tight cash flow” becomes “serious solvency risk”. That’s why it helps to understand the warning signs and the standard solvency tests used in the UK.

Common Early Warning Signs Your Solvency Might Be Slipping

One missed invoice doesn’t automatically mean insolvency. But patterns matter. Watch out for:

• Consistently paying suppliers late (or rotating who gets paid)
• Regularly using overdrafts or credit cards to cover basic operating costs
• Falling behind on HMRC liabilities (VAT, PAYE, Corporation Tax)
• Receiving statutory demands, County Court claims, or threats of winding-up action
• Needing to renegotiate payment terms frequently just to “get through the month”
• Difficulty renewing finance, or lenders asking for tighter terms/personal guarantees
• Not being able to produce reliable short-term cash flow forecasts

If a few of these are happening at once, it’s time to take a close look at solvency - and to document the steps you’re taking as a director.

How To Check Your Company’s Solvency (Practical Tests)

In the UK, there are a few widely used ways to assess solvency. Some are formal “tests” used in insolvency contexts, and others are practical checks that help you spot problems early.

Here are the key ones small businesses should understand.

1) The Cash Flow Test (Can You Pay Debts When Due?)

This is often the most practical solvency check for SMEs.

You’re asking: can the company pay its debts as they fall due? That includes:

• supplier invoices
• wages and pension contributions
• rent and utilities
• loan repayments
• HMRC liabilities (VAT/PAYE)

How to check it in real life:

• Prepare a rolling 13-week cash flow forecast (weekly is ideal).
• Include realistic timings (not hopeful timings) for customer payments.
• List all committed outgoings, including quarterly/annual bills and tax.
• Stress-test your forecast: what happens if your biggest customer pays 30 days late?

If your forecast shows you can’t pay debts on time without “something saving you” (like an uncertain sale, a hoped-for investment, or a loan you haven’t secured), that’s a solvency red flag.

2) The Balance Sheet Test (Do Your Assets Cover Your Liabilities?)

The balance sheet test looks at whether the value of the company’s assets is enough to cover its liabilities (including contingent or future liabilities, depending on circumstances).

How to check it:

• Review management accounts and the latest balance sheet.
• List liabilities properly: loans, trade creditors, tax liabilities, employee liabilities, and any known claims/disputes.
• Be cautious about asset values (for example, old stock or unpaid invoices may not be worth their “book value”).

This is where businesses can get a nasty surprise. A balance sheet might look okay if assets are recorded at cost, but if they’re hard to sell quickly or unlikely to be collected (like aged debtors), solvency could still be at risk.

3) The “Legal Action” Reality Check

Even if your accounts look stable, one serious legal or enforcement event can tip you into an insolvency position quickly.

Examples include:

• a court judgment you can’t pay
• HMRC enforcement action
• a statutory demand
• loss of a major contract leading to immediate revenue drop

If you’re already in dispute with a customer or supplier, it’s worth being extra careful about the commitments you enter into. This is also where strong contract risk management helps, such as using limitation of liability clauses where appropriate, to reduce the chance that one claim becomes business-ending.

4) Solvency For Specific Decisions (Dividends, Loans, And Distributions)

Solvency comes up sharply when money is leaving the business - for example, paying dividends, repaying director loans, or making large “one-off” payments.

If your company is making distributions, taking on finance, or repaying insiders, you should be confident (and able to show) that the business remains solvent afterwards.

It’s also important to keep director funding structured and documented. If you’re lending money to your company (or repaying yourself), clear paperwork like directors’ loan agreements can help show what’s owed and on what terms.

Directors’ Legal Duties When Solvency Is In Doubt

If you’re a director of a UK company, solvency isn’t just “good practice” - it can affect your legal exposure.

When your company is financially stressed, the key is to act early, act carefully, and act with evidence.

Your Duties Change As Insolvency Risk Increases

Directors generally have duties under the Companies Act 2006, including to act in good faith to promote the success of the company.

However, if the company is insolvent (or bordering on insolvency), or if an insolvent liquidation or administration becomes probable, directors must consider creditors’ interests. The closer the company gets to insolvency, the more weight those creditor interests carry in decision-making.

Wrongful Trading Risk (Why Timing Matters)

One of the biggest risks directors worry about is wrongful trading (under the Insolvency Act 1986). In plain English, this can become relevant if:

• the company goes into insolvent liquidation or administration, and
• before that happens, you knew (or ought to have concluded) there was no reasonable prospect of avoiding insolvent liquidation/administration, and
• you didn’t take every step you should have taken to minimise losses to creditors.

This is why “hoping it’ll turn around” without a plan can be dangerous. If turnaround is realistic, you should be able to show the work you did to assess that - forecasts, funding discussions, cost-cutting, restructuring options, professional advice, and board decisions.

Transactions To Be Careful With

When solvency is shaky, directors should be especially cautious about transactions that could later be challenged in an insolvency process, such as:

• Preferences (paying one creditor in priority to others, especially connected parties)
• Transactions at an undervalue (selling assets too cheaply)
• Improper dividends or distributions (money leaving the business when it shouldn’t)
• Taking on new credit with no genuine ability to repay

If your company has complex funding arrangements, it’s also wise to keep a close eye on who is owed what. For example, where directors or shareholders have put money into the company, understanding how shareholder and director loans operate (and the repayment order in insolvency) can help you make safer decisions.

Documenting Decisions: Minutes, Evidence, And Formality

When solvency is under pressure, it’s not enough to make the “right” decision - you want to be able to prove you acted responsibly at the time.

Good governance looks like:

• holding regular director meetings (even for small companies)
• recording solvency considerations, forecasts, and options discussed
• getting appropriate professional advice where needed
• making sure contracts and documents are executed correctly

If you’re signing or varying key documents during a restructure, make sure you execute them properly - especially if they need to be deeds. The rules around executing contracts and deeds can be surprisingly strict, and a technical error can cause disputes later.

Steps To Take If Your Business May Be Insolvent

If you’re worried your business may be insolvent (or heading that way), it’s time to go into “protect and stabilise” mode.

Here are practical steps many directors take, in a sensible order.

1) Get Clear On The Numbers (Fast)

You can’t manage solvency risks without visibility.

• Prepare a 13-week cash flow forecast.
• Identify your “must pay” items (wages, key suppliers, HMRC, rent).
• List all debts and when they fall due.
• Chase receivables actively (but sensibly and consistently).

2) Stop And Think Before Paying “Insiders”

In tough times, it’s common for directors to want to repay themselves for money they’ve put in. But repayments that look reasonable commercially can still be risky if they disadvantage other creditors.

If you’re not sure what’s safest, get advice early. It’s usually much easier to fix a plan at the start than to unwind payments later.

3) Speak To Creditors And Renegotiate Where Possible

Often, solvency problems are timing problems. A supplier might be willing to agree a payment plan if you engage early and communicate clearly.

It’s also worth reviewing your customer contracts to see:

• whether you can adjust payment terms for new work
• whether you can require deposits
• what your termination rights are (and what notice you must give)

If you’re changing arrangements with customers or suppliers, make sure the agreement is properly documented so you’re not relying on vague email chains. (If you’re unsure what forms a binding deal, it helps to understand what makes a contract legally binding.)

4) Consider Restructuring Options Early

There are several formal and informal ways to deal with financial distress. Which one fits depends on your cash flow, debt profile, and whether the underlying business is viable.

Options may include:

• informal refinancing or new investment
• cost restructuring (staffing, premises, supplier renegotiation)
• a formal insolvency process (such as a CVA, administration, or liquidation)

If you’re looking at formal processes, it’s important to understand the practical consequences. For example, company administration can provide breathing space in some situations, but it comes with strict rules and professional oversight.

5) Know When It’s Time To Close The Company

Sometimes the best decision (and the safest one for directors) is to stop trading and close in an orderly way.

That might be because:

• the business model no longer works
• debts have become unmanageable
• there’s no realistic way to return to solvency without causing further creditor losses

Even if closing is the right call, the process matters. There are different ways to close depending on whether the company can pay its debts. If you’re exploring this, understanding closing a limited company helps you avoid making things worse by using the wrong route.

6) Get Legal Advice Early (Not Just At The End)

When solvency is in question, the cost of “getting it wrong” can be far higher than the cost of getting advice early.

Early legal support can help you:

• reduce wrongful trading risk by documenting decisions properly
• avoid unenforceable or risky agreements during a restructure
• review director and shareholder funding arrangements
• manage disputes and creditor communications in a controlled way

It’s also a good time to check any personal exposure, such as guarantees you’ve signed, and whether you’ve mixed company and personal finances.

Key Takeaways

• Solvency is about whether your business can pay debts when due and whether its assets cover its liabilities - it’s not the same as profitability.
• The most practical solvency check for small businesses is a rolling cash flow forecast, backed by realistic assumptions.
• If the company is insolvent (or close to it), or an insolvent liquidation/administration becomes probable, directors must consider creditors’ interests and those interests carry increasing weight as the risk increases.
• Key risks during solvency trouble include wrongful trading and transactions that unfairly favour certain creditors or move assets out of the business.
• If solvency is uncertain, act early: tighten forecasting, renegotiate where possible, document decisions, and get professional advice.
• Where closure is inevitable, choosing the right process matters - an orderly approach can reduce risk and protect directors.
