ISP move today when to change router?

[Goberpiles316]

Hi, I am moving from Plusnet to SKY LLU service today, at what point should I swap the routers over, will the current service just stop being able to access the net? Or will it be as simple as plugging the new one it and it connecting right away?

Thanks, got home from work and net down, plugged new router in and back again, only 4mb at the moment but estimated between 10-20 meg so happy day hopefully.
