What IT Downtime Is Really Costing Your Business

IT downtime - the silent profit killer

UK businesses lost £3.7 billion to internet failures alone in 2023. Not cyber attacks. Not hardware failure. Just connectivity going down. When you factor everything else in, the true cost of poor IT is one of the most underestimated risks facing British businesses today.

It Hits Small Businesses Hardest

UK micro and small businesses accounted for £2.7 billion of that total - 72% of the UK's entire downtime bill. Small businesses aren't protected by their size. They're exposed by it.

For the average UK SME, unplanned IT downtime costs around £7,500 per year. Some individual incidents have cost businesses up to £212,000 in a single event. For most small businesses, that just isn’t cash they can afford to lose!

The Costs You Don't See

Lost sales are the obvious hit. But the real damage runs deeper.

There's the productivity drain as staff sit idle. Management time absorbed in firefighting. Delayed client work and missed deadlines. And then there's recovery - which often takes far longer than most people expect.

92% of UK businesses take 24 hours or longer to recover from a significant outage. A full working day, or more, of your business running at a fraction of capacity while your costs stay exactly the same.

The Cause Is Usually Closer to Home Than You Think

Between 66% and 80% of all downtime incidents are caused by human error - staff not following correct procedures, not sophisticated attacks or freak hardware failures. That means most downtime is preventable with the right systems and support in place.

Downtime and Cyber Risk Are the Same Problem

Poor IT doesn't just cause outages - it creates vulnerabilities. The average cost of a cyber breach to a UK SME in 2024 was £25,700, with 51% of UK cyber insurance claims coming from ransomware and malware. Outdated, poorly supported systems are where those attacks take hold. The two risks feed each other.

Here are scary stats - a recent report estimated that 51% of business are gone within two years of a severe data loss incident.

That shows that IT downtime is not an IT problem. It is a business survival problem.

Poor IT support has a cost. Most businesses only find out what it is when it's too late.
