Unless I missed it, the OP did not say when the CU (main CU not the EV) was installed, and as such, could be overdue. And yes, while sometimes EICR is done before EV install,
“I have had an Ohme e-pod for just over 12 months and not had an issue until now. 3 weeks ago I noticed a burning smell from under the stairs where the fuse box is located. Around the same time an MCB (I think) tripped. It had the tumble dryer, dishwasher and dehumidifier on the same circuit and were all on. I also had plugged in the EV. I called an electrician as an emergency the next morning and he recommended that I replace the old fuse box with a new consumer unit which I agreed to. Last night I plugged the EV in and within 30 minutes the same smell was coming from under the stairs but nothing had tripped.”
Before replacing the main CU, which was within the last 3-4 weeks, pre testing an EICR would/should have been carried to be certain the installation is safe and fault free and any work that may be required agreed with the cliant before proceeding to change the CU. When the board changed, the characteristics of every circuit has been altered, along with possibly a change to the maximum Zs allowable by installing different fuses/MCBs. Upon completion, an EIC is issued with the test readings, which proves the circuits are safe to be re-energised. @aljohno The issuing of an EIC is notifiable under part P to confirm compliance because such work is notifiable under Part P and a certificate is provided up to a few weeks later from the local building control – this is in addition to the EIC. An EICR is not required for a CU change in a private dwelling however, it is adviseable to have one if the property is rented to comply with government legislation, along with every 10 years or change of tennant. Just to note an EICR can be agreed upfront with the house owner if they wish. An EICR should not be done on completion of the CU change, as a means of charging the customer more. Equally an EICR will assess the safety, condition and compliance of the installation over time and not just after installation of any works.
The EV charger was fitted circa 12 months ago and based on how most do it, I would imagine the charger was a seperate circuit away from the main CU and the supply taken from the Henley blocks, which would have been fitted at the time of install. Again, I can only guess the emergency electrician, has brought the charger supply circuit into the realms of his work and responsibility by supplying it from the main house CU. Given he was called out on an emergency, I don’t know what he did or whether he checked for a fault (loose connection) in the charger consumer unit or whether is was more interested in getting a CU swop based on a under rated MCB tripping, but that is not the focus here and something, I’m not willing to enter into discussion with. What I will say, is I hate domestic work and avoid it like the plague.
@aljohno how did you go on with Ohme?
