I'd guess that a far bigger factor is that the US has a much higher percentage of houses the use electricity for room heating.
I believe that it is similar for water heating.
In the US there is also a high percentage of houses that use electricity for the stoves and oven and for clothes drying. A brief didn't turn up how much electricity is used for those things in the UK, but if it is like much of the rest of Europe I'd not be surprised if it is lower than in the US.
In the US around 26% of houses use electricity as their only energy source, compared to around 9% for the UK.
