Working from home can give you the freedom to choose your own hours and choose your own work, and it can also be a very cost effective way of working. If you are a parent, you might have decided on this route so that you can fit your career around your family more effectively. There are certain things you need to make sure of before you start going down this route though. The first is to check your mortgage, or if you are renting, your tenancy agreement. You may not be allowed to use your home to run a business, and these documents will tell you that information. It might mean that you will need to take out a different kind of insurance; http://www.workingmums.co.uk offers great advice and resource for any information and support you need on this topic.
Depending on the type of business you are starting, you need to think about parking arrangements if it will involve clients coming to your house, and whether or not this will affect the neighbours. You also need to think about health and safety. The great thing about working from home is that your costs will be low, much lower than if you had to commute and rent office space, and the most expensive thing will be your time.
How you price that of course, is entirely up to you. It is still very important to have a timetable when you are working for home. It is all too easy to get into habits like waking up later, or procrastinating when you know you have the whole day to work. Remember your reasoning for working for home and make life easier and more stress free by having set hours to ensure maximum productivity. Also if you know that you work best at a particular time of day, you now have the freedom to structure your day according to that.
