But the board has just been replaced, and with spare ways too. So it'll be a long,long time before renewal is necessary again.
You say that but things change pretty quick at the moment, I have a rental property that had a new board fitted 2018, then had a new board to the side fitted because an electric car charger was fitted and was AC type RCD, it has no SPD and as said type AC RCD's, on refurbishment I am going to probably change it out so the car charger can be integrated into a new board, there is not enough space for SPD and car charger and even then changing RCD's to type A for some reason is stupidly expensive so will change to RCBO's.. So basically exactly the same as the first board you posted, you could not for example fit a new circuit for smoke alarms without installing and SPD (as its an emergency circuit), then there is AFDD's that may come in...
I have another property from 2003ish that needs replacing as has no RCD on lighting circuits and you cant get the RCD's for that make of board.. My point is with solar and car chargers and all the changes going on you can't rely on "Ill make the cables short but its ok cause it'll be a long long time before renewal is necessary again"...
Why just so you can show some picture on instagram, nobody cares, stop watching Jordan too expensive Artisan, sorry but its my pet peeve is cables unnecessarily short to "Look good", I even see it on sockets, then you go to fit a different manufacturer and you have to extend the conductors cause it wont fit... Maintenance is more important than looks, it should look neat as that makes it easier to maintain but it should also have enough slack for the next guy and the double insulation should come into the enclosure (Even if it makes it look not quite as pretty)..
Sorry but its my pet peeve electricians that show off their "pretty" consumer units with no consideration for the next guy, its poor workmanship. What I think makes a good electrician is when the guy comes in after you and says "Oh thank god the last guy did a good job and left enough slack for me, makes my life a lot easier."
