FWIW I looked at the HESA data for your course
AAA Entry and 96% employed or further education at 6 months seems decent but 12% drop out is quite high and I cant see a % for 'working in a field where degree is essential' but my suspicion is that would be up to you.
In my cohort at Loughborough, folks went in all sorts of directions including finance, consulting, design, charities etc, those who stayed in engineering with UK employers went to big companies like BAE Systems, JLR, Worcester Bosch, Ford, GKN or smaller ones like Ferodo, Lotus. One joined Airbus then Boeing and went California. I also got to work in Germany and Italy in automotive for a time.
My guess is there will be a job fair at Manchester soon, they run one of the best in the country - get along and see who is there, see what inspires you
The other thing to do if you are worried about employability is to get placements, internships etc. Again Manchester is great for helping there
