Best Electric Car Lease Deals 2026: Why EVs Are Still the UK's Cheapest Company Car
Despite the Benefit in Kind rate rising from 3% to 4% in April 2026, electric vehiclesremain the most tax efficient company car choice in the UK by a wide margin - typically saving 40% taxpayers between £300 and £450 per month, versus a petrol or diesel equivalent. With the new £50,000 Expensive Car Supplement threshold, the Electric Car Grant offering up to £3,750 off qualifying models, and BiK rates fixed and protected through 2030, the maths for switching to an electric lease has actually improved in 2026. This guide breaks down the best electric car lease deals available right now and explains exactly why EVs still win on Total Cost of Ownership.
Quick Answer: Are Electric Cars Still the Cheapest Lease in 2026?
Yes. For company car drivers, electric vehicles remain the cheapest option to lease in 2026 by a substantial margin. The 4% BiK rate compares to 25–37% for petrol and diesel. For personal leasers, EVs are competitive on monthly payment thanks to manufacturer incentives, the Electric Car Grant, and lower running costs (electricity is roughly half the per mile cost of petrol). The only scenarios where a non EV currently wins on TCO are very high mileage long distance driving without charging access, or fleet operators with no charging infrastructure budget.
BiK at 4%: What It Actually Costs You
The Benefit in Kind calculation is simple: vehicle P11D value × BiK rate × your income tax bracket. For a £40,000 electric car, a 40% taxpayer pays: £40,000 × 4% × 40% = £640 per year, or roughly £53 per month. The same driver in a £40,000 petrol BMW 3 Series at a 31% BiK rate pays: £40,000 × 31% × 40% = £4,960 per year, or £413 per month. The monthly difference is £360 in personal tax alone - over four years of leasing, that's £17,280 of post tax income retained.

Why the Electric Car Grant Sweetens the Deal Further
The Electric Car Grant launched in 2026 offers up to £3,750 off qualifying new EVs priced under £37,000. The discount is applied directly to the vehicle's purchase price by the manufacturer before lease payments are calculated, which lowers the monthly rental from day one. For mid range EVs like the MG4, BYD Dolphin and Vauxhall Corsa Electric, this typically translates to £80 - £110 less per month on a 36 month lease. The grant is not means tested and applies equally to personal and business leases.
Best Electric Car Lease Deal Categories for 2026
Best Budget Electric Car Lease (Under £300/month)
The most competitive sub £300 monthly EV leases in 2026 include the MG4 EV, BYD Dolphin Surf, and Vauxhall Corsa Electric. All three benefit from Band 1 Electric Car Grant eligibility, all sit comfortably below the £37,000 grant cap, and all offer real world ranges of 200+ miles. For commuters and second car households, these deliver the lowest entry point to EV ownership currently available in the UK market.
Best Executive Electric Car Lease
For higher mileage executive drivers, the BMW i4, Tesla Model 3, and Polestar 2 currently offer the strongest TCO in the £400 - £600 monthly business lease band. The BMW iX3 - a 2026 award winner - has emerged as a particularly strong contender, with rapid charging speeds that make 400 mile motorway days genuinely practical.
Personal vs Business Lease: Which Wins for EVs?
For company directors and limited company owners, business contract hire on an electric car is almost always cheaper than personal leasing. Three reasons: monthly lease payments are an allowable business expense and reduce your corporation tax bill; VAT registered businesses can reclaim 50% of the VAT (or 100% if used solely for business); and the BiK tax exposure on an EV is small enough that the corporate tax savings dwarf the personal tax cost. Speak to your accountant or contact our specialists here at LetsTalk Leasing for a worked TCO comparison on your specific circumstances.
What About Plug-In Hybrids?
Plug-in hybrids are facing a sharp 2026 tax cliff. From April 2026, the UK has adopted the Euro 6e-bis emissions standard, which uses a longer test cycle (1,367 miles vs the previous 497 miles) that is far more reflective of real world hybrid use. This effectively erases the official low emissions advantage many PHEVs enjoyed and pushes their BiK rates up sharply from 2028 onwards. For company car drivers, plug in hybrid is no longer the safe middle ground it once was - fully electric is now the only tax efficient route.
Below can be found the New BiK rates for Plug In Hybrids.
