The 2025 IT Health Check Guide for UK Businesses

One in four UK businesses experienced a ransomware attack last year, with 32% reporting that outdated or unpatched systems were responsible for the breach. While many organisations are increasing their IT budgets, there’s still a growing need for better visibility and more proactive planning to stay ahead of emerging risks.

A structured IT health check gives you that visibility. It helps uncover vulnerabilities, improve system performance and ensure your technology is aligned with your business goals. Here’s what every organisation should review this year.

What is an IT Health Check?

An IT health check is more than just a cybersecurity scan. It brings together a series of reviews and technical assessments that evaluate the resilience, efficiency and security of your entire IT environment.

A thorough check typically includes internal and external network audits, server and infrastructure reviews, database access and setup evaluations, firewall configuration testing, penetration testing and web application security checks. For customer-facing industries like retail and hospitality, it can also highlight gaps in device reliability, connectivity between locations and support readiness for peak periods.

Why It Matters For Your Business

With growing cyber threats, hybrid work and increased reliance on cloud systems, IT health checks are absolutely crucial for business continuity. They help identify vulnerabilities, reduce costs and improve system performance before issues escalate. For lean IT teams, it’s a smart way to stay proactive and in control.

The 2025 IT Health Check: Your 10-Point Checklist

✔ Are all devices and systems supported, secure and performing reliably?
Tip: Replace ageing hardware and unsupported software that could be slowing you down or putting you at risk.

✔ Are operating systems and firmware up to date across your IT estate?
Tip: Set regular patching schedules to keep systems protected against known vulnerabilities.

✔ Are regular backups in place, and have they been tested for restore?
Tip: Make sure backups are automated, stored securely and tested at least quarterly.

✔ Is antivirus software active, updated and centrally monitored?
Tip: Use modern endpoint protection with central oversight to detect and respond to threats quickly.

✔ Is multifactor authentication enforced across key systems and apps?
Tip: MFA is one of the simplest ways to prevent unauthorised access to business-critical tools.

✔ Have user permissions and shared access points been recently reviewed?
Tip: Remove inactive accounts and apply role-based access to limit unnecessary risk.

✔ Are unused licences, duplicate platforms or legacy tools being retired?
Tip: Audit your software to cut spend, reduce clutter and streamline the user experience.

✔ Are third-party applications and plugins patched regularly?
Tip: Include all non-core apps in your update process to avoid security gaps.

✔ Do staff receive training on phishing and cybersecurity awareness?
Tip: Keep training short, relevant and regular to build better everyday habits.

✔ Is your IT support model responsive, documented and scalable?
Tip: Ensure that support processes meet current needs and can flex with future growth.

If you cannot confidently answer yes to all ten, it may be time for a deeper review of your IT infrastructure.
