How is the job market for Chemistry like?
Subscribe to your local job portal. It'll tell you more about what jobs are out there than most people can. Using Google for the term "uk job portal", I found these two sites: jobsite.co.uk and reed.co.uk (there are a lot of others). Search for positions requiring chemistry at your degree level (e.g. if you're applying for a PhD position, search for "PhD chemistry"). These job portals usually have lots of refine search options as well, such as sorting by location, salary, and so on.

I'd recommend subscribing and staying subscribed to these job alerts throughout your studies. Even if you never apply, at least you know what's out there, in case there's a change in market trends.
