The electricity price we used to calculate costs is 34 pence per kilowatt hour (kWh), because that's the current cap for a unit of electricity in the UK.
From the article
So it's 0.34 * 1 (cause they have done per hour) * energy usage in Watts.
Ignore me: clearly got home too late from a work do.
Did you miss where it says it's watts per one hour use?
This is my point. It should be stated clearly in the table that the cost is pence per hour
