GSK has sites across Cumbria (mostly Carlisle), AstraZeneca has a large base in Macclesfield, Sanofi has sites in Cheshire, Sheffield and Newcastle while in Liverpool Allergan and Eli Lilly have significant research facilities in Liverpool. The water companies United Utilities, Yorkshire water and Northumbrian water all have large water testing facilities which include microbiology. There is also a range of small medium sized companies across the North of England. So don't think there are no jobs in the North.
