Kate earns £50,000 and needs a car. A personal lease on a Tesla Model 3 costs her about £450/month after tax. Through her employer's salary sacrifice EV scheme, she gets the same car for an effective cost of roughly £250/month. Why? The Benefit in Kind on a zero-emission car is only 3% (2025/26), compared to 25–37% for a petrol car.
Because it's salary sacrifice, Kate saves income tax AND National Insurance on the amount. Her employer saves their 13.8% NI too. Insurance, maintenance, tyres, and breakdown cover are all included in the monthly payment. She doesn't need to worry about depreciation, MOT, or surprise repair bills.
But it gets even better. Kate's EV has a 60 kWh battery — that's a massive energy store sitting on her driveway. If she pairs it with solar panels and a V2H charger, her car becomes her home battery. Read the full EV + Solar strategy →
