My daughter works for that Caledonian outfit (did you know it's now Spanish? Will it become El Electrico?) so I asked her.
She says day rate is 10 point something pence per unit (she's good, if not pin-point accurate - in her defense, she deals with gas) and night rate is 4 point something. She says just ring them and they'll sort it out - it is, apparently, a computer glitch.
Don't retire on the refund - just invite me out for a slap-up meal.
