Could have been as above - polarity issue (live and neutral on opposite pins)

I’m still not sure which adapter I need though
If I used the wrong adaptor would it just not charge or is their a risk of damaging the Tesla?
The model S wouldn't charge and indicated a charging fault and to seek advice from service centre
Unless you are doing long daily commutes (80-100+ miles) you may not need a wall connector at all.
Cheap alternative might be a Commando Socket, with a "permanently attached" cable
Don't all commando sockets require the use of the UMC?
I was thinking of Commando Socket plus a Commando-to-type-2 cable, looks like they are about £200 ... so maybe not much in the way of savings, but that would offset wear-and-tear on UMC (plus having to coil it up wet to put in the car when needed etc)
I think points to consider:
If charging outside, having to coil up the UMC when wet / horrible if you want to take it with you (or any issues with leaving it "permanently connected outside")
Wear and Tear on the UMC - its an expensive cable to replace
Continuous running on 13AMP wiring.
Loss of efficiency - 13AMP not as efficient as 7kW for charging, although difference might only be pennies. If pre-conditioning the car that will eat a large percentage of the available power.
Those odd occasions when you do come home empty and need to go out on a long trip again tomorrow. Moot if a decent 3rd party charger / Supercharger nearby.

I do commute 100 miles every day, to be fair, but even for those who don’t I really can’t see that the saving justify the severe impairment in the experience.
Every day's a school day. This is essentially an aftermarket UMC, right?
Anyone know what tesla charges for a second umc in the uk? Looks like $275 US so if it's near that they'd be competitive against after market options.
The length really depends what the socket arrangements are where you are going to charge. In the four years I’ve had EVs I’ve bought a 20m outdoor cable reel (only used twice) and a 5m extension (used many times). So, on that basis I now only carry the 5m in the car, and only take the 20m when I know I’ll definitely need it.Also, I'm thinking of carrying around some heavy duty extension cable (and a dribox) in the car (to borrow juice on extended visits to family).
What length should I go for? 5m, 7m, 8m, 10m or 15m?
Just want to avoid lugging around unecessarly long cables as already have a umc and type2 cable in the trunk cable loot box.

The majority of the cost will be the digging and covering it back up again.I am currently charging my M3 (had for 3 weeks) off a standard 13A circuit. As mentioned, it charges at between 9-10 mph. My outlet is very close to the fuse board and garage door; it charges reliably and does not get warm. It’s fine for my day-to-day use, but I do tend to do the odd 200mile+ return journey.
I would like a 7kW charger, but living in an old house my supply and main fuse are rated at only 40A. I need to get the distribution company (WPD) to upgrade my supply (including the cable) - which will involve digging up my drive. My supply company will also need to replace my meter. I have a Tesla supercharger within 5 miles and destination charges at most locations I travel to - so wondering whether to push ahead. Has anyone in a WPD region had their supply upgraded?

if I may be so bold, I would enquire to the cost of upgrading to a 3 phase supply.
If it’s little more, I would consider going down that route.
The future is electric (cars, heat pumps, etc) and you may find that 3x100A will future proof you a bit more.
If it’s not a free upgrade, then the suggestion of going to 3-phase sounds a good one.
