The cost saving should come from having controllers working from a central pool managed by fewer managers. LCY will gain from having more space available from aicraft parking. I also hope that a centralised pool should enhance promotion for controllers and providing relocation packages are properly put together, an improved quality of life and a stable home platform. But cynics amongst us know that software, hardware and communication gremlins will stuff things up in ways we can not imaging. And if NATS is run like any other business, they will screw their workers over at every opportunity but... this time controllers can shut down multiple airports. They will now have more industrial power than ever.
