I started a course about 15 years ago, however, as the wife was studying for her work qualification at the time, 1 of us had to give up as nothing was getting done around the place and my study was not critical. My dad did his degree via the OU.
My experience was good though (I was starting with maths and then planning on adding a computing element), we had a number of evening sessions at the local college to go through some of the course work and the course tutor was in contact regularly by email. I'm guessing these days there will be better technology for on-line discussions than we had back then.
There is a lot of work to do to complete the modules, you will need to be able to devote the time and if you don't, it is very easy to get behind schedule.
If you want the qualification and can devote a regular number of evenings (or other suitable time), then go for it.
