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:

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:

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:

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, 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.

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.

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.

 

Choosing the Right IT Maintenance Services Provider

IT maintenance and repair services are an investment you make not only in the functionality of your computer equipment, but in the continuity of your business as a whole.

This begins with a thorough IT health check to identify the areas where you can make the fastest gains, but it can include ongoing IT equipment maintenance to keep everything running in an optimal state.

You need an IT support and maintenance partner you can trust, who keeps you fully informed and can scale your IT maintenance services as your business grows.

With decades of expertise and thousands of happy clients, Venom IT is that partner. To find out more about our IT maintenance services for SMEs and fast-growing businesses, contact Venom IT today.

Adopting best practices for cyber security in the office and when working remotely can protect businesses of all sizes from costly data breaches and information theft.

The Cyber Security Breaches Survey 2025 found that 43% of UK businesses experienced a cyber security attach or breach in the preceding 12 months, equivalent to about 612,000 firms nationwide.

This is down from 50% in the previous year, a drop driven by businesses adopting best practices in cyber security. Some of the precautions taken by British businesses in 2024 included:

We have put together this top 10 cyber security checklist that office workers can follow to better protect data, passwords and backups against would-be threats, as well as to improve cyber security at home for hybrid workers.

Cyber Security in 2026

The fall in breaches in 2024-25 should not be seen as a drop in danger. Instead, it is a sign of better preparedness among UK businesses of all sizes, which in turn is translating into fewer successful cyber attacks.

In order to continue this trend in 2026, firms need to address the remaining disparities in cyber security policies. For example, 76% of the UK’s largest businesses run training sessions to improve awareness of cyber security tips for employees, but this figure drops to just 19% when SMEs are included.

Our list of workplace and home cyber security tips covers ten of the most important issues you can address to protect your data, regardless of the size of your organisation.

Top 10 Cyber Security Best Practices 2026

Below is our cyber security checklist office workers can follow to defend against cyber attacks in 2026 and beyond.

While this list is in no particular order, these are ten of the biggest, most commonly encountered cyber threats, making them the best place to start when planning training on cyber security tips for employees and remote workers.

1. Strong and unique passwords

Weak and duplicated passwords are commonplace among office-based and home workers alike, and they’re still a threat to business cyber security. Nearly three quarters (73%) of UK businesses now have password policies in place to tackle this. (Source: DSIT)

Ideally, passwords should be:

Regularly changing passwords – and preventing reuse of old passwords – is also worth considering, as this can proactively prevent access using old leaked or hacked passwords. For more tips on password management, check out our guide here.

2. Multi-factor authentication

Multi-factor authentication (MFA) requires the use of two or more forms of authentication to log in. The most basic version of this is two-factor authentication, sometimes written as 2FA.

An example of this is when logging onto internet banking. You may have a username, a password, a PIN, a security question and/or a unique login code generated by a key fob or banking app.

Only 40% of businesses are using this kind of approach as of the Cyber Security Breaches Survey 2025, making this an area where the majority could do better. (Source: DSIT)

3. Keep devices up to date

Updating devices is one of the easiest ways to improve cyber security at home and in the workplace. Many updates and software patches are released to close newly identified security vulnerabilities, so it’s important to install them as soon as possible.

Automatic updates remove the burden of remembering to do this. Updates can be scheduled to download in the background at off-peak times and install overnight.

In many cases, modern computers can reboot to the exact same state – including any open programs and unsaved work – although it’s always a good idea to save documents to the cloud in real-time as you work on them.

4. Adopt email common sense

The old combination of ‘scams and spams’ is still one of the most important target points for workplace and home security tips in 2026. Phishing attacks – including fraudulent emails and attempts to make employees access fraudulent websites – were reported by 85% of UK businesses that experienced a cyber attack in 2024-25. (Source: DSIT)

Yet only 55% of businesses have a process in place for staff to follow when they receive a phishing attack. Again, this makes phishing awareness training and clear anti-phishing policies a good prospect when auditing cyber security in the office.

A sensible tip to follow is the five-second rule: Before opening an email attachment, clicking a link or replying to an unfamiliar address, stop for five seconds to consider whether you trust the sender, and to look for anything suspicious like poor spellings and grammar, high-risk attachments like .exe files, and to check the destination URL of hyperlinks.

5. Improve Wi-Fi hygiene

Wireless networks are convenient, but they pose unique risks to cyber security. Three of the biggest threats to tackle include:

  1. Employees connecting work devices to public Wi-Fi
  2. Employees connecting their own devices to workplace Wi-Fi
  3. Members of the public connecting to workplace Wi-Fi

In general, if you want to provide wireless internet access to visitors, you should have a second public connection in place. Keep your private workplace network for authorised personnel only.

The DSIT survey found that just 33% of UK businesses have a separate visitor network, while only 31% require the use of a VPN (virtual private network) to improve cyber security at home for remote workers.

6. Away-from-screen rules

We all need a coffee or bathroom break from time to time, but those ‘AFK’ (away from keyboard) moments can be some of the biggest short-term threats to cyber security in the office, as many employees do not lock their workstation when they step away.

This is a good issue to raise in employee cyber security training, as it’s something that can be improved via a culture of security awareness. Timeout tools that automatically lock the screen after a certain period of inactivity can also help.

Make sure employees don’t have access to change the settings on these – even if you instil the importance of security during away-from-screen times, some will try to deactivate the screensaver or standby setting rather than retype their password when they return.

7. Separating work & personal use

Maintaining separation between professional and personal use of devices is best practice and again, something you can include in home cyber security tips for remote workers, who may be more likely to use their personal laptop for work.

A good way to improve cyber security at home without using completely separate devices is to create an additional user account for work purposes. This can comply with workplace password policies, email security and other precautions.

Having separate accounts or devices for business use can also boost productivity, by reducing employees’ access to the distractions (e.g. apps and bookmarked websites) that may be found throughout their personal devices.

8. Secure backups & cloud storage

Fast wireless internet means there’s no reason why your data should be stored locally on devices that could be lost, stolen, damaged or destroyed. Set up secure online backups, ideally in real-time but at least on a daily basis, for all critical data.

This protects you against cyber attacks and other threats to business continuity:

Nearly all medium-to-large businesses surveyed by DSIT in 2024-25 had data backups in place, accounting for 96% of respondents. This technology is affordable to small businesses in 2026 – if you’re not backing up data to the cloud, make this your year to catch up!

9. AI scams awareness

The risk of cyber AI scams is growing at a rapid pace, and should feature on any cyber security checklist office workers are asked to follow.

AI can analyse vast quantities of data to identify vulnerabilities and to mimic specific phrasing used by real-life individuals when attempting to impersonate them. In extreme cases, AI-generated photographs and even videos (with audio) can be used to add to the realism of a scam.

Phishing – already the single most prevalent form of cyber security attack – is finding a new lease of life due to the potential to incorporate AI into phishing attempts. Employee awareness is crucial to combating this, along with creative techniques like the use of ‘safe words’ and other analogue authentication methods that are never typed into the network.

10. Reporting suspicious activity

Perhaps the most important of our cyber security tips for employees is to report suspected incidents, whether or not a breach has occurred. A lack of reporting is one of the biggest risks to cyber security in the office.

This can be difficult for management, because it requires a blame-free culture. Employees, both on-site and at-home, should be empowered to protect business data against theft or compromise, but if an incident slips through the net, they MUST feel able to report it.

Appropriate disciplinary action and/or re-training can follow at a later date, but in the first instance the most important response is to mitigate the breach, secure your systems and comply with any reporting requirements by your industry regulator or ICO.

Start With a Cyber Security Health Check
