It should be remembered that the OP's question pertains to new works, the extent of which I believe to be the additional board, tails and outgoing (what appears to be) tuff-sheath cable. Unless I've missed something, the main board, armoured cable and 2g socket were pre-existing.
Cleating on new cables could be neater, but that's not an issue raised by the OP. While tuff-sheath is certainly tougher than sheathed and insulated tails, it offers little in the way of cut resistance. Yes it will be RCD protected, but I don't think it should be overlooked if damage by power tools is the main concern.
The socket could be better placed, but OP hasn't expressed any concerns about its position and it doesn't appear to be part of the recent works.
What I do find strange is where the tails come trough - perhaps this was the extent of a permali box on the other side, perhaps it was a case of point and drill or perhaps there are other reasons unknown to us. Regardless, it's not an issue in terms of OP's concernsand nor is it from a regulatory perspective.
OP mentions that they raised the issue of potential damage when the job was near completion. The installer could certainly have taken the time to protect the tails in some way, but was it feasible to do so at the time? Was there a nearby wholesaler open and could the job have still been completed on the same day? Was the additional taime required to strip the board, protect tails and re-dress chargeable? I'm not casting aspertions at either the OP or the installer, but simply highlighting a few (of many) considerations that are easy to overlook when levelling criticism from afar.
I can clarify that the new works are the Garo DB for a new EV charger (Tesla Wall Connector Gen3) and the SWA that you see going into a compression gland on the Garo board... I asked for the existing SWA going to shed from the main CU to also be added to the new DB, so that it's also PEN protected, as we're looking to install a hot tub from the shed CU and it would provide some protection for that circuit also...
A side note: It just occurred to me after someone noted further up - it doesn't look like the armour has been earthed if they've used a plastic compression fitting... probably something that also needs addressing I imagine, as I'd prefer if any SWA armour on the property is earthed for obvious reasons.
Correct, sockets are less of an issue honestly, but given that there's now the topic of adding additional protection in the way of conduit or a plywood box - I may actually shift them across and up to make covering the area easier, as currently, it's difficult to do that without blocking the sockets.
The tails come through directly from the very top right corner of the meter box directly on the other side of the wall. It was a bit of a drill and pray situation and the drill luckily came through just to the left of the existing SWA for the shed.
It's a bit of a long story but the guy wasn't very happy that I suggested to him that adding RCD protection to the existing shed SWA at the source (main CU) wasn't actually required (armour is bonded at source already and sub-CU has all RCBOs). He was adamant that all buried SWA had to be RCD protected... anyway, I digress... by the time we got the issue of the exposed tails - it was obvious that he was annoyed at me for second-guessing him, so I just stayed clear of him until he was done. He didn't actually add an RCD in the end, stating that "it's your property, so it's up to you".
Anyway, the plot thickens as I've realised he's reduced my shed feed from 63A to 40A (which gives me zero wiggle room for running my power tools in the shed when the hot tub is running) and I cannot source suitable Garo modules to support the higher rating... so looks like I'm going to get my regular electrician to put the shed SWA back into the main CU and run a new 6mm run to the hottub from the Garo DB. Hands are tied now it seems. I'll sort out moving the socket and adding from boxing to tidy things up.
Thanks very much to everyone that has provided help so far, it's greatly appreciated.
Bonus question... 2x continuous 40amp loads running through a single 40A contactor? Is that right? Sorry, I'm obviously just an amateur but I feel like I'm having to second-guess everything at the moment.
