ICAEW Annual Conference 2026: Economic Uncertainty, Rising Business Costs and the Challenges Ahead

On Friday 16 October, I attended the ICAEW Annual Conference 2026 at the InterContinental London – The O2. The event brought together accounting and finance professionals, business leaders and industry experts to discuss the challenges and opportunities facing UK businesses.

This year's conference theme was "Turning business complexity and change into value", which felt particularly relevant given the economic uncertainty, rising costs and regulatory changes that businesses are currently navigating.

With the Autumn Budget just days away, there was plenty to reflect on. Here are some of my key takeaways, alongside the latest economic developments and what they could mean for businesses.

1. The UK economy is performing better than expected – but challenges remain

There was some encouraging economic news ahead of the conference.

According to the latest figures from the Office for National Statistics, the UK economy grew by 0.1% in August 2026, despite economists having anticipated a slight contraction. Over the three months to August, GDP increased by 0.7%.

This suggests that the UK economy has shown greater resilience than many expected, despite ongoing global uncertainty.

However, the headline figures do not tell the whole story. Growth remains uneven across different sectors, and businesses and households continue to face significant financial pressures.

2. Household finances remain under pressure

One of the major concerns is the continued impact of rising energy prices and inflation.

Higher energy and fuel costs are affecting household budgets, leaving consumers with less disposable income. This can have a direct knock-on effect on businesses, particularly those operating in retail, hospitality and other consumer-facing sectors.

There is also uncertainty surrounding interest rates. While future Bank of England decisions cannot be predicted with certainty, persistent inflation and energy price pressures have increased concerns about possible interest rate rises.

For businesses, this could mean higher borrowing costs, more expensive financing and further pressure on cash flow.

My view: Businesses should remain cautious when preparing cash-flow forecasts and avoid assuming that borrowing costs or operating expenses will fall in the near future.

3. The construction sector is facing particular difficulties

The construction industry is one area where the economic challenges are especially visible.

The latest ONS figures show that construction output fell by 1.0% in the three months to August 2026, with private housing new work declining by 3.2%.

For construction businesses, subcontractors and property-related companies, weaker activity can create significant challenges, particularly when combined with rising material, labour and financing costs.

Maintaining healthy cash flow, managing outstanding invoices and reviewing project profitability are increasingly important.

4. Small businesses are feeling the impact of higher employment costs

Another important concern is the increasing cost of employing staff.

The rise in employers' National Insurance contributions, introduced in April 2025, continues to place additional pressure on many small and medium-sized businesses.

For businesses operating on tight margins, increased employment costs can influence decisions about recruitment, pay increases, investment and expansion.

These pressures may also create risks around payroll compliance. Although informal reports occasionally suggest that some businesses are turning to undeclared cash payments, such claims should not be treated as evidence of a widespread practice.

Paying employees in cash is not itself illegal, but all earnings must be properly recorded and relevant PAYE and National Insurance obligations met.

My view: Rather than taking unnecessary compliance risks, businesses should review staffing costs, payroll arrangements and available reliefs, including eligibility for Employment Allowance.

5. The Autumn Budget – what should businesses expect?

With the Autumn Budget scheduled for 28 October 2026, uncertainty remains over the government's next tax and spending decisions.

Businesses will be watching closely for possible changes affecting taxation, employment costs, business rates and investment incentives.

ICAEW has already called for greater clarity and certainty for businesses and urged the government to avoid further increases in employment taxes.

Given the pressure already facing smaller employers, stability and predictability would be particularly welcome.

Until the Chancellor makes the announcements, however, speculation should not be mistaken for confirmed policy.

My view: Business owners should review their financial position now, but avoid making significant tax or investment decisions based purely on Budget rumours.

6. Cyber security is no longer just an IT issue

One of the most important messages from the wider conference programme was the growing significance of cyber security.

Cyber criminals are becoming increasingly sophisticated, using techniques such as phishing, impersonation and AI-generated communications to trick businesses into disclosing sensitive information or authorising fraudulent payments.

Small businesses are not immune. A successful attack can result in financial losses, disruption to operations, reputational damage and the loss of confidential client information.

Practical safeguards include:

• Using multi-factor authentication and strong passwords.

• Keeping systems and software updated.

• Training staff to recognise suspicious emails and telephone calls.

• Independently verifying changes to suppliers' bank details.

• Maintaining secure backups and a clear incident response plan.

Cyber security should be considered an essential part of business risk management, not simply a technical responsibility.

7. Technology and AI are changing the accountancy profession

Another important theme was the increasing role of artificial intelligence and digital transformation.

AI offers opportunities to automate routine processes, improve financial reporting and support better business decisions.

For accountancy practices, this creates opportunities to spend less time on repetitive administrative tasks and more time helping clients understand their finances, plan ahead and grow their businesses.

At the same time, technology must be introduced responsibly, with appropriate controls around accuracy, confidentiality and data protection.

The continued development of Making Tax Digital is another reminder that businesses need to keep their accounting systems and record-keeping arrangements up to date.

Final thoughts: Planning ahead in uncertain times

My main takeaway from the ICAEW Annual Conference 2026 is that, although the UK economy is proving more resilient than expected, significant challenges remain for businesses and households.

Rising employment costs, energy prices, economic uncertainty, cyber threats and changing technology are all affecting the way businesses operate.

For small business owners in particular, the priority should be to remain informed, protect cash flow, maintain compliance and plan ahead rather than simply react to events.

At North Kent Chartered Accountants, we believe that good accountancy is about more than preparing accounts and tax returns. It is about helping businesses understand the bigger picture and make informed financial decisions.
