How Employment Rights Act changes affect small business cash flow planning

Recent changes to UK employment law, while bringing welcome new rights and flexibility for employees, have introduced significant new pressures for small business owners. With 'day one' rights for flexible working and new leave entitlements now in effect, your biggest outgoing – payroll – has become more complex and less flexible to manage. This makes the income side of your business more critical than ever. If you've ever let invoice chasing slide, now is the time to build a robust system, because predictable cash flow is no longer a 'nice-to-have'; it's an essential buffer against these new fixed-cost realities.

This article breaks down the key employment law changes affecting UK small businesses and explains why they make a disciplined, automated approach to getting paid on time an absolute necessity for survival and growth.

What's Changed? A Breakdown of New UK Employment Rights

From April 2024, a raft of new employment regulations came into force. While each change seems small in isolation, their cumulative effect is a significant shift in the employer-employee relationship, particularly concerning workforce planning and cost management. Here are the main changes you need to be aware of.

Flexible Working Requests from Day One

Previously, an employee needed 26 weeks of continuous service before they could formally request a flexible working arrangement. Under the new Employment Relations (Flexible Working) Act 2023, this right now applies from the very first day of their employment.

• The Change: Any employee can make two statutory requests for flexible working (e.g., changes to hours, times, or location of work) in any 12-month period, starting from day one.
• The Impact on Your Business: While you can still refuse a request for legitimate business reasons, you must handle the process in a "reasonable manner" and respond within two months (down from three). This creates an immediate administrative task for every new hire who makes a request. More importantly, it can create operational complexity as you try to accommodate different working patterns, which can impact team collaboration and project delivery schedules.

The New Right to Carer's Leave

The Carer's Leave Act 2023 introduces a new statutory leave entitlement for employees who are also unpaid carers.

• The Change: Employees are now entitled to one week of unpaid leave per year to provide or arrange care for a dependant with a long-term care need. This is a day-one right.
• The Impact on Your Business: Although the leave is unpaid, the absence of a key team member, even for a week, can have a direct impact. Projects can be delayed, deadlines missed, and client work postponed. This directly affects when you can issue an invoice and, consequently, when you get paid. For a small team where every member is critical, this can cause significant disruption.

More Flexible Paternity Leave

The rules around statutory paternity leave have also been updated to offer more flexibility for new parents.

• The Change: Under the Paternity Leave (Amendment) Regulations 2024, fathers and partners can now take their statutory two weeks of leave as two separate one-week blocks, at any point within the first year after birth or adoption. Previously, it had to be taken as a single block of one or two weeks within the first 56 days.
• The Impact on Your Business: This change makes long-term planning for cover much more difficult. Instead of planning for one predictable two-week absence, you may now have to manage two separate, short-notice absences at any point in a 12-month window. This adds another layer of unpredictability to your resource planning.

Extended Redundancy Protections

Perhaps one of the most significant changes for cash flow planning is the extension of redundancy protection for pregnant employees and new parents.

• The Change: The Protection from Redundancy (Pregnancy and Family Leave) Act 2023 extends the period of special protection. Previously, employees on maternity, adoption, or shared parental leave had priority for suitable alternative roles in a redundancy situation. This protection now starts from the moment an employee tells you they are pregnant and lasts for 18 months after the birth or placement of the child.
• The Impact on Your Business: This drastically reduces your flexibility to make redundancies as a cost-cutting measure. If your business faces a sudden downturn – for example, a major client fails to pay a large invoice – your ability to scale back your largest cost (headcount) is severely restricted. This makes having a strong cash reserve, fuelled by on-time payments, absolutely non-negotiable.

The Knock-On Effect: How These Changes Directly Impact Your Cash Flow

These legislative changes create a dangerous "certainty mismatch" for small businesses. Your outgoings have become more rigid and complex, while your income remains as variable as ever.

The 'Certainty Mismatch': Fixed Costs vs. Uncertain Income

Payroll is your largest and most relentless expense. The new laws cement this. You have statutory obligations to your team that you cannot defer. You can't ask your employees to wait an extra 30 days for their salary because your client is paying you late.

This creates a serious imbalance:

• Costs: Fixed, predictable, and legally mandated. Your flexibility to reduce them (e.g., via redundancy) has been curtailed.
• Income: Often uncertain, unpredictable, and reliant on your client's payment processes and goodwill.

When a large invoice is 30 or 60 days overdue, you have to find the cash to cover payroll from somewhere else. This might mean dipping into your own savings, taking out expensive short-term loans, or delaying payments to your own suppliers – all of which harm your business's financial health.

From Productivity Dips to Delayed Invoices

Let's trace a common scenario. Imagine you run a small digital agency with five people.

1. A key designer is leading a project worth £15,000, due for completion and invoicing on the 25th of the month.
2. They unexpectedly need to take a week of Carer's Leave.
3. The project milestone slips by a week. You can now only raise the invoice on the 2nd of the following month.
4. Your payment terms are 30 days, so cash was expected around the 25th of the next month. Now, it's not due until the 2nd of the month after.
5. Worse, the client is disorganised and pays 15 days late.

The cash you budgeted for has arrived nearly seven weeks later than originally planned. Meanwhile, you've had to cover two full monthly payroll runs in that time. This single, small, legitimate staff absence, combined with average client payment delays, can blow a significant hole in your cash flow forecast.

The Hidden Cost of Administrative Overhead

Every flexible working request that needs to be considered, every piece of leave that needs to be arranged, and every project plan that needs to be re-shuffled takes up your most valuable resource: your time.

As a small business owner, time spent on internal administration is time not spent on:

• Winning new business.
• Delivering client work.
• Improving your product or service.
• Chasing overdue invoices.

This administrative burden is a real, albeit indirect, cost. It distracts you from the revenue-generating activities that are essential for keeping the business afloat.

Why Your Old Credit Control 'System' Isn't Good Enough Anymore

Many small businesses operate with an informal credit control process. This usually involves manually checking the bank account, realising a payment is late, and firing off a polite (or slightly panicked) email when you get a spare five minutes.

In this new environment, this ad-hoc approach is a recipe for disaster.

The Problem with Manual, Ad-Hoc Chasing

When you're juggling project delays and new admin tasks, invoice chasing is often the first ball to be dropped.

• It's Inconsistent: You might chase one client but forget another.
• It's Inefficient: It relies on your memory and requires you to manually check your accounts, find the invoice, and compose an email each time.
• It's Emotionally Draining: Asking for money can be awkward. This discomfort often leads to procrastination, allowing debts to age further.

A system that relies on you "remembering" to do it is not a system; it's a gamble.

The Danger of Relying on Client Goodwill

It's a common misconception that chasing an invoice will damage your client relationship. The reality is that most late payments are not malicious. They are a result of disorganisation, staff absence, or simple human error in your client's accounts payable department.

Your friendly reminder is not an accusation; it's a helpful prompt that gets your invoice back to the top of their to-do list. By not chasing, you are effectively providing your clients with an interest-free loan at the expense of your own business's stability. With your own costs and obligations now more rigid, you can no longer afford to be your clients' unofficial lender.

Building a Resilient Cash Flow Strategy for the New Reality

To counteract the new pressures, you need to shift from a passive to a proactive accounts receivable strategy. This involves tightening your processes and using technology to ensure nothing slips through the cracks.

Step 1: Tighten Your Foundations – Contracts and Invoicing

Good credit control starts before you even do the work.

• Clear Payment Terms: Your contract or terms of service must explicitly state your payment terms (e.g., "Payment due within 14 days of the invoice date").
• Reference Late Payment Rights: State that you reserve the right to charge interest and compensation on overdue invoices as per the Late Payment of Commercial Debts (Interest) Act 1998. Simply having this in your terms can encourage timely payment.
• Invoice Promptly and Accurately: Send your invoice the moment the work is complete or a project milestone is met. Double-check that it includes all the information the client needs to process it, such as a Purchase Order (PO) number, correct contact person, and a clear breakdown of services.

Step 2: Implement a Proactive, Systemised Chasing Process

Don't wait until an invoice is weeks overdue. A professional, predictable follow-up process shows you are organised and serious about payment. A typical, effective schedule looks like this:

1. Polite Pre-Reminder: An email sent 3-5 days before the due date. Frame it as a courtesy: "Just a friendly reminder that invoice #123 is due for payment on [Date]."
2. Due Date Reminder: A reminder sent on the day payment is due if it hasn't been received.
3. First Overdue Notice (7 Days Late): A polite but firm email. "Following up on invoice #123, which is now 7 days overdue. Please let us know when we can expect payment."
4. Second Overdue Notice (14 Days Late): The tone becomes more serious. "Invoice #123 is now 14 days past due. Payment is required urgently to avoid further action."
5. Final Notice (30 Days Late): State your intention to apply late payment charges or escalate the matter. "Invoice #123 is now 30 days overdue. If payment is not received within 7 days, we will be adding statutory late payment interest and compensation."

Step 3: Leverage Automation to Ensure Consistency

Manually executing the schedule above is time-consuming and prone to error. This is where automation becomes a small business owner's most powerful ally.

When you're busy dealing with the fallout from a staff absence or a new flexible working arrangement, a manual chasing process will fail. An automated system will not. Tools like InvoiceReminder connect directly to your accounting software (like Xero, QuickBooks, FreeAgent, or Sage) and execute your chosen chasing schedule automatically. It sends professionally worded emails on your behalf, ensuring every invoice is followed up consistently and on time, without you having to lift a finger. It removes the administrative burden and emotional stress, freeing you to focus on managing your business.

Understanding Your Rights: The Late Payment Act

For business-to-business transactions in the UK, you have a statutory right to charge interest and a fixed compensation sum on overdue invoices. This is a powerful tool, not necessarily for generating extra income, but for incentivising clients to pay on time.

• Statutory Interest: You can charge interest at 8% plus the Bank of England's base rate. This rate can change, so it's always wise to check the current BoE base rate when calculating it. The interest is calculated daily.
• Fixed Compensation: You can also claim a one-off compensation payment for each late invoice to cover the cost of chasing the debt. The amount depends on the size of the debt.

Debt Amount	Fixed Compensation You Can Claim
Up to £999.99	£40
£1,000 to £9,999.99	£70
£10,000 or more	£100

You don't have to go to court to claim these charges. You can simply add them to a new, updated invoice sent to the client. The mere mention of these statutory rights in your final reminder email is often enough to prompt immediate payment.

This is general guidance, not legal advice, and your specific contract terms may vary. However, for most UK B2B invoices, these rights apply unless you've explicitly agreed to different terms.

Frequently asked questions

Do these employment law changes apply to all businesses?

Yes, the new rights to request flexible working from day one and to take Carer's Leave apply to all employees from their first day of employment, regardless of the size of the business.

Can I refuse a flexible working request?

You can, but you must have a valid business reason from a list of statutory grounds (e.g., the burden of additional costs, a detrimental impact on performance or quality). You must also handle the request in a 'reasonable manner', which includes discussing it with the employee. The process itself requires management time.

Is charging late payment interest bad for client relationships?

It can be if handled aggressively from the start. It is best used as a deterrent in the final stages of a chasing process. The primary goal is to get your original invoice paid, not to collect interest. A clear, automated, and polite reminder process should mean you rarely have to resort to it.

What's the first step I should take to improve my credit control?

The very first step is to review and clarify your payment terms. Ensure they are clearly stated in your client contracts, proposals, and on every invoice you send. The second, equally important step is to define and commit to a consistent chasing schedule.

How much does it cost to automate invoice chasing?

Costs vary, but some powerful tools have free entry points. For instance, InvoiceReminder's core plan for sending unlimited automated email reminders via its platform is currently available at no cost, with no card required to sign up. Paid plans typically add more advanced features like SMS reminders and reporting.

I use an accountant. Shouldn't they be handling this?

Your accountant is a crucial advisor for your financial strategy and can help you set up robust systems. However, the day-to-day operational task of chasing invoices usually remains with the business owner. Many accountants can help you implement a tool to automate the process or may offer a dedicated credit control service for an additional fee.

Take control of your cash flow

The new landscape of employment law means that having predictable, timely revenue is no longer optional. With payroll costs more fixed and workforce planning more complex, you cannot afford to let late payments drain your cash reserves. Automating your invoice chasing is the single most effective way to protect your business.

InvoiceReminder is designed for UK small businesses, freelancers, and accountants who want to stop chasing invoices by hand. It connects to your Xero, Sage, QuickBooks, or FreeAgent account and automatically sends your customised sequence of reminder emails, ensuring you get paid faster and more predictably. You can currently get started with the Free plan, which includes unlimited email reminders at no cost. InvoiceReminder is built by the team behind WeCovr, a firm which has arranged over 1,000,000 insurance policies in the UK and is authorised and regulated by the Financial Conduct Authority.
