Do you know what kW your shower is?
(1) 40A set aside as 100%
(2) Add the remainder together 32+32 +16+16+6+6 = 108
(3) 40% of 108 =(40×114/100) = 43.2
(4) 40+43.2 = 83.2kW current maximum demand
(2) 108+32 for charger =140
(3) 40% of 140 = (40×146/100) = 56
(4) 40+56 = 96kW new maximum demand with EV charger
Cut-out fuse upgrade to 100A BS7671
