During my recent (29th Dec) trip to the Gatwick Service Centre, I used their supercharger stalls to top the battery off at 33p / kWh. I had to go into my Tesla account to see this, and noticed that I'd charged there on the 8th Dec for 30p / kWh. So it looks to have gone up 10% in 3 weeks.
It's not surprising given the state of the energy market but definitely something to keep an eye on.
