I highly doubt that. Electric kettles are just about 100% efficient, and the only difference between a 3kW kettle and a 2kW one is how long it'll take to boil. The total energy consumed will be more-or-less the same.

Are you perhaps conflating it with the EU regulations on vacuum cleaners going in around 2017? As with all EU regulations, this of course resulted in a decent bunch of EU-bashing in UK media by the usual suspects - despite less-power-hungry vacuum cleaners being just as effective as the more power-hungry ones, and power consumption being inflated by manufacturers to market their vacuums, as plenty of people believed that "bigger number = more suck = more better".
