Blurb: One could argue the requirement for surge protection came in in 2019 where risk of transient overvoltages causing harm to life, interruption of public services, or significant financial loss. However, importantly the National Committee listened to this feedback and simplified the requirements. In BS 7671:2018+A2:2022, the regulation 4.1 was modified. The complex risk assessment, the Calculated Risk factor, and the “greyscale map” of the UK were removed. Instead the standard from 2022 states 1, 2 & 3 above to apply to all of the UK. Therefore the date concerned falls under BS7671 Amendment 2 2022 of which your charger and solar/battery predate.
That said whils’t not strictly a requirement, I’m a fan of surge protection, especially whole house surge protection to (in the unlikely event) protect that expensive TV/HiFi. As my previous comment, to avoid the risk while charging I’d recommend surge protection for the EV charger as its not expensive c.£35 for the equipment + installation (not alot)
Where, I am now having more of second thoughts to my previous comment, is your consumer unit is less than 10 years old and almost certainly predates modern requirements, I question the need to spend c£400-500 on a consumer change given it all tests out and you have had no problems since installation or the installation of solar!
