Common IT Mistakes SMEs in South East London Should Avoid

Running a business in South East London is no small job. Whether you’re based in Bromley, Bexley, or Eltham, chances are you’ve had to be the manager, the marketer, the bookkeeper... and yes, the IT department too.

We get it. But small IT mistakes can lead to big problems later. Here are a few things we often see, and how to fix them before they cause real trouble.

Mistake 1: Not Backing Up Your Data Properly

Relying on files being “somewhere in the cloud” isn’t a backup plan. We’ve seen businesses lose weeks of work because they assumed Microsoft or Google were handling everything behind the scenes. A proper backup doesn’t have to be expensive, and it can save your business when things go wrong.

Mistake 2: Sharing Passwords

It’s common. It’s quick. And it’s a huge risk. When everyone uses the same login, there’s no accountability, and a much higher chance of being hacked. Tools like Microsoft 365 make it easy to manage users properly and securely.

Mistake 3: Using Personal Email for Business

We still see it all the time. If your team is using personal Gmail or Hotmail accounts, you’re losing control over business data and communication. Setting up proper business email takes minutes, and instantly makes your company look more professional and secure.

Mistake 4: Skipping Updates and Antivirus

Many small businesses don’t have time to keep systems updated or check whether antivirus is running. But this stuff matters. Outdated software and unprotected devices are the easiest way in for viruses, ransomware, and scams.

If any of this sounds familiar, don’t worry, we can help. SE CloudTech works with small businesses across South East London to get their systems running right. We keep it simple, keep it secure, and keep it local.
