Moving hosting across the pond will not necessarily create longer load times.
Light travels insanely fast. What can slow it down is the number of 'hops' through different routers, and the speed of your hosting company's server. I've seen some servers/ip's in the states with insane routing, ridiculous numbers of hops and they are much slower than reaching a site in the UK that has a more direct route and fast servers.
The intercontinental lines are all fiber these days, your data is transferred insanely fast.
Play around with traceroute and you will soon discover that geographic location and distance is not what matters. You may be in LA and trying to reach a site in Texas and the fastest route might be through NY and CH!
