well... the French government is trying to kick-start a homegrown offshore wind industry (against the spirit of the EU which forbids industrial policy of course). They apparently didn't have any such concern in the UK. This presumably adds a bit of cost, because you're talking about creating an industry practically from scratch.

The UK now presumably has a certain amount of sunk-cost infrastructure for servicing the building of offshore farms, lowering the cost of additional farms. I guess.
