Bristol would be a great shout. Hundreds if not thousands of designers and engineers made redundant or otherwise re-purposed at Dyson just up the road due to their canned EV project (and all their employees live in Bristol anyway). Plus Bristol's heritage in engineering is why it's home to major sites for Airbus, Boeing, Rolls Royce and the MOD along with a whole host of hidden/unknown R&D centres. Even Toshiba have an R&D lab here developing tech for smart cities, swarm robotics and 5G. University of Bristol are also currently building a new £500mil enterprise campus.
I'm obviously bias - although they're not my industries at all - but yeah, there's a lot of talent, creativity and innovation here.
