Security:  If you are the only person who uses the computer in your home office, don't think that it doesn't need a password.  Passwords are an important part of your defence against hacking attempts, as well as helping to secure your information if your computer is stolen.  Also consider the physical security of your home office and perhaps use window locks, security screens and a burglar alarm.  If your home office can be seen from the street, use window blinds or curtains, especially if working at night as your computers can easily be seen from the outside when your lights are on.    

Ongoing maintenance:  Without an in-house expert to keep your computers running, their performance will slowly degrade and their security will be at risk if they are not maintained. It's important to ensure that software updates are installing correctly when they are released and that tasks like temporary file removal, defragmentation and virus scans are all occurring regularly. Talk to your Computer Troubleshooter about how they can easily take care of this for you.

Comfort:  You may not have a big corporate budget for desks, but if you spend a long time at your computer it's important that you reduce your risk of overuse injuries.  Look at an ergonomic, adjustable chair, a foot rest and a comfortable mouse and have your desk, keyboard and monitor all at the correct height.  Also consider the placement of your desk in your office, to reduce any screen glare from your windows.    

The separation of home and business:  Most home offices are also the place where the household bills are paid and are sometimes where the kids play computer games or do their homework. If your work computer is also your home computer, separate user 'profiles' can be handy to restrict your children's access to your business files (e.g. to prevent accidental deletion).  You might also consider extra security software or internet filtering software to prevent your children from introducing nasty malware onto your computer.  Use a separate paper filing tray for the 'paperwork of life' to keep it away from your business documents. And a second telephone line or a Voice over IP number is a great way to stop business calls from coming through on your home phone. Then you can also switch on the phone answering system after-hours to enjoy some undisturbed family time.
