I agree with Jamar. Generally it's a decision between staying on internatl. roaming of your home provider vs. buying a new local SIM abroad. As you have a Verizon iPhone which is labelled a "world phone", it'll work in the UK on GSM-networks.

Unfortunately, Verizon's roaming rates are excessive: look here. It's better with some other US providers. Then it's worth comparing complacency of staying with roaming to the hassle of buying a new SIM. But in your case it's the difference between $30 and $300.

In the UK it's straighforward. Any SIM you buy from an operator's store (EE, O2, Three or Vodafone) is much cheaper than Verizon's roaming. No registration necessary, no language barrier like in France. You can also go to one of the small cellphone shops often run by immigrants. They are very intested to set up your device. While you have to pay some extra $$ or rather ££ for it and they will sell you a plan which may be lucrative for them, it saves you some work.

Just stay away from the resellers like Tesco. While they have the best deals around, they also have almost no service and often a minimal customer support.
