How National Insurance Changes in 2025 Will Impact Employers

In April 2025, significant changes to National Insurance Contributions (NICs) will come into effect, impacting employer costs across the UK. These reforms are part of the government’s broader fiscal strategy, but for businesses, they represent a new financial burden at a time when cost control and operational efficiency are more critical than ever.

With rising employment costs, companies need to reassess how they allocate resources. One strategic approach to mitigate these expenses is outsourcing non-core business functions—particularly IT and network engineering. This blog explores the impact of the National Insurance changes, the increasing financial pressure on employers, and how outsourcing IT services can be a cost-effective solution.

What’s Changing in National Insurance?

Several key reforms are set to take place in April 2025 that will increase employment costs for businesses:

• Increase in Employer NIC Rate: The employer NIC rate will rise from 13.8% to 15% on salaries above £5,000. This means businesses will pay higher contributions for each employee on their payroll.
• Lowering of the NIC Threshold: The earnings threshold at which employers start paying NICs will decrease from £9,100 to £5,000 per year. More salaries will now fall within the NIC chargeable bracket, increasing the overall tax burden.
• National Living Wage Increase: The government has confirmed that the National Living Wage will rise by 6.7% to £12.21 per hour. While this benefits employees, it further increases payroll costs for businesses.

The combined impact of these changes means that businesses will need to spend more on maintaining their workforce—potentially leading to tighter recruitment budgets and reduced headcounts.

How Will This Affect Employers?

1. Increased Payroll Expenses

For every employee earning above the NIC threshold, businesses will now pay a higher percentage in contributions. In industries that rely on skilled labour, such as IT and network engineering, these costs can quickly add up.

Example: The Cost Impact on a Business with 150 Employees

Let’s consider a company with 150 employees, each earning an average salary of £35,000 per year. Based on a typical business structure, we estimate that around 20% of employees are on minimum wage.

Impact of NIC Rate Increase

• Under the previous NIC rate of 13.8%, the employer NIC cost per employee was: (£35,000 – £9,100) × 13.8% = £3,571 per employee. Total NIC cost: £3,571 × 150 = £535,650 
• Under the new NIC rate of 15%, the employer NIC cost per employee will be: (£35,000 – £5,000) × 15% = £4,500 per employee. Total NIC cost: £4,500 × 150 = £675,000
• Increase of £138,870 per year

Impact of Lowering the NIC Threshold

• Under the old threshold of £9,100, NIC was only payable on salaries above this amount. The reduction to £5,000 means NIC is now chargeable on an additional £4,100 of salary per employee. Total NIC cost per employee: £4,100 × 15% = £615
• Additional  £92,250 per year (£615 × 150 employees)

Impact of National Living Wage Increase

• If approximately 20% of employees (30 employees) are earning minimum wage, their annual salary increase will be:
• • • • New annual salary: £12.21 × 37.5 × 52 = £23,803
      • Previous annual salary: £11.45 × 37.5 × 52 = £22,308
      • Salary increase per employee: £1,495
      • Total wage increase: £44,460 per year

Total Additional Cost Due to 2025 National Insurance Changes

• NIC rate increase: £138,870
• NIC threshold reduction: £92,250
• National Living Wage increase: £44,460
• Total additional employer cost per year: £275,580

This substantial cost increase will require businesses to carefully evaluate their budgets and consider alternative workforce strategies to manage their financial health.

2. Pressure on Recruitment Budgets

With wage increases and higher tax contributions, businesses may find it more difficult to justify hiring additional full-time employees. This is especially challenging for IT teams, where demand for expertise is high but budgets are constrained.

3. Need to Maximise Efficiency with Limited Resources

Companies will need to explore ways to optimise operations, ensuring that productivity remains high while costs remain under control. One of the most effective ways to do this is by outsourcing key functions to trusted external providers.

The Case for Outsourcing IT and Network Engineering

Outsourcing IT and network engineering functions to a specialised provider like Opticore IT offers several advantages in light of the increasing costs associated with direct employment.

1. Cost Savings

By outsourcing, businesses can convert fixed employment costs into variable expenses. Rather than paying salaries, benefits, National Insurance contributions, and training costs, companies can access skilled IT professionals on an as-needed basis. This eliminates many of the financial pressures associated with permanent hires.

For example, a London-based network engineer earning £65,000 per year will now cost an employer £8,925 in NIC contributions, bringing the total employment cost to £73,925 per year. This does not include pension contributions, training, or other employee benefits. By outsourcing, businesses can reduce these additional overheads, allowing them to allocate resources more effectively while still accessing top-tier IT expertise.

2. Access to Highly Skilled Experts

Recruiting and retaining top IT talent is expensive, especially with rising wages and employer NICs. By outsourcing, businesses gain access to experienced network engineers and IT specialists who stay up to date with industry best practices. This ensures that IT operations are managed by experts without the overhead costs of in-house employment.

3. Increased Operational Flexibility

Outsourcing provides businesses with the flexibility to scale IT resources up or down based on project needs. Whether responding to seasonal demands, integrating new technologies, or managing large-scale IT transformations, outsourcing ensures that businesses have the right expertise at the right time without long-term hiring commitments.

4. Reduced Risk and Compliance Burden

With ever-changing regulations in cybersecurity, data protection, and IT infrastructure compliance, businesses face increasing risks associated with maintaining an in-house IT team. By outsourcing to a trusted provider like Opticore IT, businesses can ensure compliance with industry standards while mitigating security risks and reducing the administrative burden of keeping internal teams up to date with evolving regulations.

5. Enhanced Business Continuity and Support

Outsourced IT services often include 24/7 support, proactive monitoring, and disaster recovery solutions. This ensures that businesses experience minimal downtime and can quickly recover from IT failures, security breaches, or network outages—capabilities that would require significant investment to maintain in-house.
