I've only seen a brief mention here, but the UK announced a new huge BIK tax incentive for EVs last week which I think has a good chance to take UK to Tesla's number 3 market going forward.
BIK tax rates are paid on company cars because the car is a "benefit in kind" which is essentially a supplement to salary.
This year UK BIK tax rates are at 16% to 37% of the sale price per year - with the the rate based on emissions. This rate is then multiplied by the employee's tax rate (20%, 40% or 50%) - I would guess the majority of company cars go to employees on the 40% tax rate.
So for example a car with CO2 emissions at 100-104g/km would pay 25%, for a 40% tax bracket and £30k car price, would pay 25%*40%*30 = £3k per year, or £9k over a 3 year lease ($11.3k).
From next tax year (April 2020) the EV BIK tax rate will be 0%, then 1% in 2021 and 2% in 2022. So compared to a 100h/km £30k ICE, this is equivalent to a c.$11k EV incentive over 3 years of ownership.
My read of the rules is that the new tax rate will apply to EVs even if they are on the road already today - So the amount of monthly tax will suddenly reduce in April 2020, but it should not cause companies to delay EV purchases today.
The UK also has a £3.5k ($4.4k) EV grant which i assume will also apply to the company cars (can anyone confirm this?) taking the total 3 year incentive to $15.4k.
Also, no BIK tax is paid on electricity charging costs provided by your employer.
The market for BIK company cars in UK is likely 350k-500k per year (compared to a total UK car market of 2,400k). This is similar in size to the entire car market in the Netherlands (450k) and significantly larger than the Norway car market (150k).
This is now a very significant incentive and it seems hard to justify purchasing a ICE car via the BIK system now there are EVs such as Model 3 available. This tax change will likely also encourage people to acquire cars via their companies rather than in person (an untaxed EV is now much better value than a pay rise or bonus) so should act to increase the overall UK company car market.
In addition to this, the UK also provides a grant up to 75% of home chargepoint installation costs, and has just announced all new homes will be required to have an EV chargepoint and that all non-residential buildings undergoing major renovation projects must introduce chargers to 20% of parking spaces.
Considering UK petrol prices are over double the US average, the 2.4 million annual UK car demand is starting to look very well positioned to transition to EVs. The main obstacle is FUD and lack of knowledge of the EV options available and TCOE advantage.
