You'll probably have more fun if you go with company (plus it's useful to have spotters and other people to figure out beta), but there's no reason you can't go on your own and give it a go.
If you are in Crewe, there is some great bouldering nearby in The Churnet Valley. You could also head to The Roaches where this is some good easy stuff. Other great beginner spots are Cratcliffe and Burbage South boulders.
There is info on the net (eg. loads of pics and vids at peakbouldering.info) but life will be easier if you buy a guidebook. Just don't expect to be ticking off V3's straight away - outdoors stuff demands a lot of different skills to indoors.
There is some bouldering around Chester, eg. Frodsham, Helsby, Harmers Wood. There is a new guide which covers the area: Cheshire & Merseyside Sandstone.
You can use the find crags page to search for bouldering in any area:
