Thanks I added it to supercharge.infoA couple of weeks ago there were some photos of Tesla equipment (looked like two charger cabinets and foundations for 8 stalls) at the Gloucester Southbound services as well - no groundworks visible but an area of the car park was fenced off which I reckon is at approx (51.818800, -2.224400). I don't think they've been publicly shared / tweeted though.
