In today’s digital-first world, many businesses unknowingly operate with outdated infrastructure, unpatched security vulnerabilities, or inefficient IT processes.
A routine IT health check is one of the most cost-effective ways to maintain security, reduce downtime, and support growth.
But how often should it be done and what should it cover?
How Often Should You Perform an IT Health Check?
Minimum: Once Per Year
The bare minimum recommendation for most UK SMEs is an annual health check to ensure systems are secure, compliant, and functioning efficiently.
According to the UK Government’s 2024 Cyber Security Breaches Survey, 50% of medium businesses reported a cyber breach or attack in the last 12 months, highlighting the need for regular reviews.
Recommended: Quarterly
For organisations handling sensitive data, operating in regulated sectors, or scaling quickly, a quarterly IT review helps catch vulnerabilities and inefficiencies early.
After Any Major Event
You should always conduct a health check:
- After a cybersecurity incident
- Before or after a cloud migration or office move
- Following major staff turnover
- When adopting new software or hardware
What Should an IT Health Check Include?
Here’s a clear, step-by-step breakdown of what a professional IT audit should review:
1. Network Infrastructure Review
- Identify performance bottlenecks
- Test routers, firewalls, and switches
- Ensure Wi-Fi networks are secure and properly segmented
Cisco’s Annual Cybersecurity Report consistently highlights misconfigured or outdated network equipment as a leading attack surface in SMEs.
2. Cybersecurity Audit
- Antivirus and endpoint protection review
- Patching and update schedules
- User access levels and credential management
- Firewall rules and penetration testing
According to the NCSC, poor password hygiene and unpatched systems are still the most common causes of security breaches in UK businesses.
3. Backup & Disaster Recovery Systems
- Confirm automatic backups are running
- Test recovery scenarios
- Check cloud vs. local backup balance
A study by IBM Security found that the average cost of a data breach in 2024 was £3.8 million, making regular backup testing mission-critical.
4. Software & Licensing (Especially Microsoft 365)
- Identify unused or duplicate licenses
- Check for MFA (Multi-Factor Authentication) usage
- Ensure data-sharing settings are secure and compliant
Microsoft reports that MFA can block over 99.9% of account compromise attacks.
5. Hardware & Device Performance
- Audit device age and spec
- Check OS versions and encryption status
- Flag devices approaching end-of-life
Industry best practices from HP and Dell recommend replacing core hardware every 3–5 years for optimal performance and security.
6. User Productivity & IT Experience
- Monitor login speeds and system lag
- Gather user feedback on tools
- Spot training gaps (e.g. underused M365 features like Planner, Teams integrations, etc.)
What Are the Benefits of Regular IT Health Checks?
- Strengthened cybersecurity posture
- Improved network performance
- Better value from IT investments
- Smoother compliance with GDPR and Cyber Essentials
- Lower long-term support costs
