How Much Should IT Cost a Small Business in the UK? (2026 Guide)
For most small and mid-sized businesses, IT costs are one of the least understood parts of the budget. Many companies either overspend without realising or underinvest and suffer from poor performance, downtime, and security risks.
This guide breaks down what you should be spending on IT—and how to tell if you’re getting value.
What Percentage of Revenue Should IT Cost?
As a general benchmark:
3% – 5% of revenue → typical for stable SMEs
5% – 8% → growth-focused or tech-reliant businesses
8%+ → usually inefficient or over-engineered
If you’re significantly outside this range, it’s worth reviewing.
Typical IT Cost Breakdown
Most businesses spend across:
Managed IT support (MSP)
Microsoft 365 / cloud subscriptions
Cyber security tools
Hardware (laptops, servers, networking)
Backup and disaster recovery
Ad hoc projects and consultancy
The issue isn’t just cost—it’s how well these are managed.
Signs You’re Overspending
You don’t understand what you’re paying for
Your IT provider rarely challenges your setup
You’re paying for unused licences
Costs increase every year without clear ROI
Signs You’re Underspending
Frequent downtime or slow systems
Security concerns or outdated setups
Reactive IT support only
No long-term IT strategy
The Hidden Cost Problem
Many SMEs don’t realise:
The biggest IT cost isn’t your provider—it’s inefficiency.
Lost productivity, poor systems, and bad decisions often cost far more than the monthly IT bill.
How to Optimise IT Spend
Audit all subscriptions and licences
Benchmark your MSP pricing
Align IT with business goals
Introduce strategic oversight (not just support)
Final Thought
The goal isn’t to spend less on IT. It’s to spend smarter.
If your IT isn’t delivering clear business value, it’s time to reassess.
