Help with EV Bypass
Posted: Wed Apr 08, 2026 7:45 pm
Hey all
New Fox user here!
I recently had a new battery installed and I had an EV charger installed 2 months prior by a different installer.
I discussed bypassing the EV charger with the installer and my recollection was that this would easily be bypassed. I charged my EV last week and the following morning noticed that it had depleted my battery so I asked the installer and he suggested that we’d discussed this and I opted against a £250 cost as I’d need a new consumer unit.
However, reading through posts on here it seems that if my EV has its own consumer unit, that I don’t need get another. I asked the installer and he agreed and said it would be an easy rewire and a local electrician can sort for around £80 and that I’d need 2 extra Henley blocks, but nowhere else on here have I seen installs with 4 Henley blocks, I found the suggestion cheeky when he misinformed me to begin with.
I tried to move the CT clamp to the live going into the house, but it puts my battery on charge/discharge (depending on the way round).
I have home assistant set up to get around the EV stuff for now, but it’s not very future proof and sounds like an incorrect install.
Is there something I can can do with the CT clamp (or as I’ve seen other posts on Reddit is buying another CT clamp to cancel out the EV load possible?)
And if not, do I really need 2 more Henley blocks?
I have attached an image of the before and after the battery install, to the right is the EV consumer unit and to the left is the battery consumer unit.
Any help would be appreciated, thanks!
