Why IT Health Checks & Equipment Maintenance Matter

IT equipment maintenance is a ticking time bomb for many businesses, as more and more of their computing and networking hardware slips into legacy status and, ultimately, becomes obsolete.

A regular IT health check can prevent this, by looking for signs of wear and tear, poor reliability, and ageing systems that should be upgraded, updated or completely replaced.

This is not a false economy: in 2024, a global survey by ITIC found that a single hour of downtime costs more than $300,000 (£220,000) for 90% of medium to large enterprises, and most (54%) can’t even calculate the cost of IT outages in their business.

In this guide, we will look at the value and benefits of IT maintenance services for your business, to help you avoid falling into the financial cost and reputational chasm of unscheduled outages.

What is an IT Health Check?

IT health checks are one of a suite of IT infrastructure solutions offered by support partners like Venom IT.

For some businesses, a regular IT health check is mandatory. For example, you must submit an updated IT health check report when applying to connect to the UK government’s Public Services Network (PSN).

Some of the main areas that fall within the scope of an IT health check include:

External Testing

Also known as penetration testing, this checks that your internet-connected equipment is secure, including web servers, email servers and network firewalls.

Internal Testing

This checks the build and configuration of your server(s) and workstations, installation of up-to-date software patches, and remote solutions like laptops and USB memory sticks.

While the PSN health check is largely focused on network security, comprehensive system health checks are not just about protecting your business against cyber attacks. Instead, they are an important element in your ongoing IT equipment maintenance plan.

Crucially, a proactive approach to IT support and maintenance prevents unplanned downtime, protecting you against reputational risks, lost revenues and compliance costs.

What does IT Equipment Maintenance Involve?

IT maintenance and repair services can be tailored to the needs of your business and can scale as you grow.

For example, depending on the size of your organisation, the complexity of your IT systems is likely to increase:

• Standalone computers/laptops with no network
• Secure on-site network with no external access
• On-site internet-connected server with web access
• Multi-site cloud-enabled network with remote access

This is why it’s important to work with an IT support and maintenance partner like Venom IT, who can adjust your IT health check over time to focus on the elements that are most important to your business.

Elements of IT Equipment Maintenance

In terms of what’s actually involved, IT equipment maintenance is a lot like getting your car serviced. Experienced engineers inspect, test and monitor your hardware to identify any potential performance issues and physical damage.

This may include:

• Testing battery levels and power performance
• Physically cleaning dust and dirt (especially from fans)
• Checking the physical reliability of cables and connections
• Looking for environmental issues (e.g. excess heat due to direct sunlight)
• Identifying old and obsolete components to upgrade or replace

Your IT health check can also include your software. This ranges from creating secure backups of your data and essential programs, to deleting obsolete files and clearing space in your RAM to improve performance.

Again, good IT maintenance services are tailored to your organisation, equipment and processes, and you should receive a full report of the findings.

Your IT support partner may also make recommendations of ways you can improve your processes to protect your equipment against outages in the future, for example by using protective cases and purpose-made bags to carry portable equipment and protect it against physical damage during transit.

Why IT Equipment Maintenance is Critical for Business Continuity

The complexity of modern-day IT infrastructure solutions means regular IT equipment maintenance is more important than ever to ensure business continuity.

In 2025, Uptime Institute’s Annual Outage Analysis found the leading causes of downtime in data centres:

1. Power (54%)
2. Cooling (13%)
3. Network (12%)
4. IT systems (11%)
5. Colocation (3%)

An IT health check will obviously help with the condition and reliability of IT systems (e.g. hardware/software), but can also tackle the other issues listed, by improving power and cooling performance, preventing network problems, and optimising equipment used in colocation scenarios.

Counting the Cost of Poor IT Equipment Maintenance

The 2023 Cost of Downtime Report from Beaming surveyed UK businesses to predict the impact of internet connectivity outages. It found that 850,000 companies, about 15% of the UK economy, would start to lose revenues the moment they lost connectivity.

In 2023 alone, British businesses experienced nearly nine million connection failures, costing a total of more than 50 million hours of downtime. On average, SMEs are worst hit, suffering 3-4 outages per year and losing 19 hours of productivity, equal to about 2.5 business days.

Across the economy, 42% of all businesses reported some amount of downtime, with a combined cost of £3.7 billion. That’s more than the Welsh Government’s entire capital funding for 2026-27 (£3.6 billion).

A Bumpy Landscape of IT Infrastructure Solutions

Obsolete and legacy hardware is one of the single biggest challenges to effective IT equipment maintenance. Older equipment is typically less reliable, out of warranty, and is often no longer supported by security patches and firmware updates from the manufacturer.

The extent to which your organisation suffers from this may vary. For example, the 2025 State of Digital Government Review revealed that in the UK public sector, some organisations’ IT infrastructure includes up to 60-70% legacy systems, while others are at only around 10%.

Overall, it’s estimated that 28% of UK central government IT infrastructure consists of legacy systems – but most of the public sector has no register of IT assets specifically designed to track this.

Key Benefits of Regular IT Health Checks

The list of benefits of regular IT health checks is practically endless, and can vary depending on the nature of your business and the size of your existing IT infrastructure.

Here are 10 key benefits of regular IT health checks, in no particular order:

• Cost Savings: Replacing legacy hardware reduces running costs due to excessive energy consumption and one-off repair expenses.
• Cyber Security: Software patches and firmware updates help to protect hardware against attacks via the network, email and/or internet.
• Data Protection: Well-maintained disks and devices help to ensure compliance with data protection legislation and industry-specific regulations.
• Employee Productivity: Maximise productivity while reducing frustration, and ensure your employees comply with your company’s IT processes.
• Longevity: Hardware lasts for longer in good condition, with fewer component failures and improved reliability.
• Optimise Resources: Identify IT assets that could be used better, so you can allocate your investment to where it makes the most profit.
• Reduced Downtime: Prevent avoidable outages, so that your business does not suffer a complete interruption to productivity.
• Software Speed: Removing old software and unused Registry ‘startup’ entries frees up RAM and disk space, allowing systems to run faster.
• System Scalability: Do the best with the IT infrastructure you have, while identifying (and budgeting for) growth opportunities via future IT investment.
• Written Records: Fully documented IT audit reports give you a paper trail you can show to regulators to evidence your commitment to data compliance.

A tailored IT equipment audit will focus on the aspects that matter most to your business, while providing a valuable overview of your systems to steer your future decision-making on IT upgrades and purchases.

Common Risks of Neglecting IT Maintenance

The risks of neglecting IT maintenance can range from the relatively minor, such as poor system performance, to major events like data centre outages and server fires.

• Performance Problems

Performance, productivity and profit go hand in hand. If your employees are hampered by legacy workstations that take minutes to boot up every day, or slow servers that mean it takes ages to transfer files or check emails, your business’s bottom line will suffer as a result.

• Security Risks

Your cyber security can be put at risk due to poor IT maintenance. Older equipment might not receive firmware updates and security patches from the manufacturer. Your hardware might not support modern encryption methods. Your workforce might start to use their own, less secure devices that are faster and more reliable.

• Outages and Fires

In extreme cases, your business could suffer a prolonged outage due to a hardware failure. Dusty, overheating equipment can also catch fire, which is why it’s essential to check the condition of your most intensively used hardware e.g. your office server.

These are just a few of the issues you might encounter due to a lack of IT maintenance and repair services. As IT hardware ages, these risks develop further – which is why you need regular IT health checks from a maintenance provider you can rely on.
