At that rate the probability of getting electrocuted in either the UK or France is pretty miniscule!
The very slightly higher rate in France could be attributed to any number of factors.
The UK has one unique difference. The original system of domestic wiring was so impractical that it had to be completely replaced during the 1950s and 1960s. Older houses in the UK used a vast array of BS546 sockets of at least 3 different and completely incompatable sizes.
British houses wired before the 1950s often had 1 15A socket in the kitchen for the kettle another by the fireplace for the "electric fire" and a few tiny 5A sockets scattered around for lamps and the "wireless" (radio).
By the 1950s these systems were completely inadequate due to the arrival of countless domestic appliences. The sollution was to introduce BS1363 and ring circuits, making re-wiring relatively simple.
On the otherhand, in ALL European countries domestic wiring was always based on radial circuits but the design of sockets and circuits was a little more sensible than BS546 and did not require any drastic changes. "Schuko" and the French grounded outlet have been around for quite a LONG time as have their now phased-out non-grounded counterparts.
The result has been that older wiring has managed to stay in service for much longer as it's often quite adequate and is not incompatable with modern plugs.
Older French houses that have not been rewired will sometimes still have non-grounded outlets in areas that will quite happily accept a 16A CEE 7/7 plug without completing the earth connection. (The later grounded sockets didn't accept the fatter pins of grounded plugs)
I would suspect that accidents caused by Class I appliences being used without an earth connection would account for the very slightly higher rate.
If you walked into a UK house with 1930s/40s wiring you physically wouldn't be able to insert a modern plug.
Compulsary RCDs in most European countries have, however, done a lot to reduce fatalities.
Ireland's fatality rate before the introduction of manditory RCDs in 1980 was substantially higher.
Almost all accidents here are now caused by the "darwin factor".. There's not a lot you can do if someone insists on doing bad DIY work or driving a tractor through 20kV powerlines.
