Upgrade meter tails to 25 mm for EV charging

Hi, Our main fuse is being upgraded to 100 A for charging an electric car. The network provider SSE has advised that the meter tails should be upgraded to 25 mm and this has to be done by the electricity supplier (i.e. Bulb) before charging the car. How do we go about this?

Contact Bulb and ask them. This is a forum for customers, so not the best place for account-related queries.

For general information, upgrading meter tails costs £120 through bulb (12/08/2019).
