Quick answer: The cost of IT downtime in the UK is usually quoted as a headline per-minute figure, and those figures are close to useless for a 20 to 80 person business in Aberdeen. Your real number is your own: idle staff cost, plus lost or delayed revenue, plus the recovery tail that runs for days after systems come back. Most growing businesses that work it out honestly land somewhere between £1,000 and £4,000 for a single lost morning, and almost all of that is preventable with monitoring, tested backups and a provider who spots problems before your team does.
Search for the cost of IT downtime and you get big numbers. £44 billion a year across the UK, according to a 2026 study by Managed247. £11,000 per minute in one widely repeated figure. Gartner’s much quoted $5,600 per minute, which dates from 2014 and averages across every industry and company size.
None of those numbers describe a 40 person engineering firm in Dyce. They are averages weighted by enterprises that lose transaction revenue by the second. Quote them in a board meeting and the first person to check the source will take the whole argument apart.
Here is the more useful view, and it is the one we take with clients. Downtime cost is a calculation you do once, with your own payroll and your own revenue, and then keep on a single page. It takes about twenty minutes. The number it produces is usually smaller than the scary headlines and far more persuasive, because nobody can argue with it.
Most business owners picture a total outage: the server is down, nobody can work, everyone goes home. That happens, but it is rare. The expensive version is quieter.
Beaming’s research on UK internet failures found businesses lost an average of 19.1 hours to connectivity problems in a single year, spread across many small incidents rather than one dramatic one. In our work with SME clients, the slow drip causes more lost hours than the headline outage, and it almost never gets recorded anywhere.
When nobody is measuring it, it never appears in any budget, and the case for fixing it never gets made. That is the bit most growing businesses get backwards.
Work in hours, not minutes. Minutes make the figure look dramatic and make the maths less credible.
Step 1: Staff cost per hour. Take the number of people who genuinely cannot work when the system is down, multiply by their average hourly cost including employer NI and pension. Twenty people at £28 per hour fully loaded is £560 per hour.
Step 2: Apply a realistic idle factor. People are rarely 100% blocked. They make calls, do paperwork, take an early lunch. In our experience 50% to 70% is honest for an office based team. Twenty people at 60% blocked is £336 per hour.
Step 3: Revenue effect. For most SMEs this is delayed rather than lost. Orders still arrive, jobs still get done, they just get done later. Only count genuinely lost revenue: the quote you did not send in time, the customer who went elsewhere, the billable hours you cannot recover. Be conservative here, because this is the line a finance director will challenge.
Step 4: The recovery tail. This is the one everybody misses. When systems come back, there is a queue: rekeyed data, chased customers, a backlog of support calls, an engineer’s time, and in serious cases legal or insurance work. A rule of thumb we use is to add 50% of the outage cost again for recovery. On a serious incident it is far more, which we covered in detail in our post on what happens after a cyber attack.
So for a 20 person business losing one morning, four hours: £336 x 4 = £1,344 in staff time, plus £500 in genuinely lost or delayed work, plus 50% recovery allowance, giving roughly £2,760. Once a quarter, that is around £11,000 a year. That is a real budget line, and it is defensible.
Two local factors show up repeatedly in the conversations we have here.
The first is supply chain expectation. A large share of Aberdeen SMEs supply energy, engineering or professional services into much bigger organisations, and those organisations increasingly ask about IT resilience during procurement. An outage that stops you responding to a tender portal before a deadline does not just cost you a morning, it costs you the tender.
The second is the shape of the working day. Where a chunk of your team works offshore rotation, from client sites, or from home in Aberdeenshire, they depend entirely on remote access. When connectivity or identity services fail, those people go from productive to completely blocked, with no option to walk over to a colleague’s desk. Distributed teams raise the idle factor in the calculation above.
Weather plays its part too. Power interruptions during the winter storms are not unusual in the north east, and a business without an uninterruptible power supply on its core kit can turn a two minute cut into a two hour recovery.
It is worth being precise, because the fix depends on the cause.
Hardware age and failure. Still the most common cause we see in businesses running kit past its supported life. Ageing servers and unreplaced laptops fail at the worst possible moment.
Missed updates and patches. Unpatched systems both fail and get attacked. Patching is dull, scheduled, invisible work, which is exactly why reactive providers skip it.
Connectivity. Single line, no failover. A £40 per month 4G or 5G backup line pays for itself the first time the main circuit drops.
Human error and access problems. Someone deletes a folder, or a former employee’s account breaks a process nobody documented. Our secure leaver checklist covers the offboarding side of this.
Cyber incidents. The most expensive category by a distance, because the recovery tail is measured in weeks. Ransomware does not just stop systems, it stops trust.
Poor file structure. Less obvious, but real. Teams waiting on files nobody can find, or working from three versions of the same document, lose hours weekly. We wrote about getting that right in SharePoint vs OneDrive vs Teams.
You do not need to buy everything. In order of return for a growing business:
Notice that most of these are process, not hardware. That is deliberate. Downtime is rarely solved by buying a bigger box.
Ask them for your downtime figures for the last twelve months. Total unplanned outage hours, number of incidents, average time to resolve, and how many of those incidents were flagged by their monitoring before a member of your staff phoned in.
That last part is the tell. If most incidents reach your provider because one of your team reported them, you are paying for a service that watches you rather than your systems. A provider who is genuinely proactive can produce those numbers without hesitation, because they are already reporting on them.
Where nobody can give you the figures at all, that is your answer, and it is the same one we hear from most businesses before they move to a managed service.
Published averages range from around £137 to £450 per minute for SMEs, but those figures are skewed by larger and transaction driven businesses. A more realistic planning figure for a 20 to 80 person Aberdeen business is £500 to £900 per hour of full outage, plus a recovery allowance. Calculate your own using staff cost, idle factor, lost revenue and recovery time.
There is no official benchmark for SMEs, but well managed businesses we work with typically see under four hours of unplanned downtime a year on core systems. If you are losing a morning every quarter, something structural is wrong rather than unlucky.
It reduces it where the provider is monitoring, patching and testing backups rather than waiting for the phone to ring. The mechanism is boring and it works: most outages give warning signs, and somebody has to be watching for them. Ask any provider to show you their monitoring and their restore test records before you take the claim on trust.
For most growing businesses in Aberdeen, yes. A 4G or 5G failover typically costs under £50 per month and removes an entire category of outage. It is usually the cheapest single downtime reduction available.
At least once a year, and after any significant change to your systems. A plan that has never been tested tends to fail on the details: an out of date contact list, a backup that restores in eighteen hours rather than two, or a key step that only one person knew about.
Downtime is one of the few IT costs you can quantify without a consultant. Do the calculation, put it on one page, and compare it with what proactive management would cost you. For most growing businesses the comparison makes the decision obvious.
If you would like a second pair of eyes on it, we run a short IT resilience review for Aberdeen businesses: we look at your backup and restore position, your monitoring coverage, your single points of failure and your realistic recovery time, and give you the downtime figure in writing. No obligation, and you keep the numbers either way.
