CHAPTER 1

The leasing industry's defining moment

The UK car market recorded its strongest new car sales since 2019 in early 2026. March alone saw 196,059 electrified vehicles registered — the highest single month on record for that category. Behind that headline sits a quieter story: the leasing industry is now the primary engine of the UK's vehicle fleet, and it is being tested like never before.

Business contract hire (BCH) fleets grew 10% in 2025, reaching 983,388 cars. Personal contract hire (PCH), meanwhile, shrank 4.3%, squeezed by household budget pressure. The direction of travel is clear — leasing is becoming more corporate, more structured, and more dependent on tax policy than at any point in its history.

 

983k BCH fleet cars in 2025 (up 10%)

48% of BCH fleet now electric

33% 2026 ZEV mandate target for new sales

22.4% actual BEV share in Q1 2026

 

The gap between the ZEV mandate target and the actual market is the central tension of 2026. Manufacturers are required to ensure 33% of their new car sales are zero-emission this year — rising to 80% by 2030. But BEVs represented just 22.4% of UK registrations in Q1 2026, despite rising year-on-year from 20.7%. The mandate will be missed in headline terms, though ZEV mandate flexibilities and the double-counting of electric vans are expected to soften the shortfall for some manufacturers.

“The strongest new car market since 2019, with the highest ever volume of EV registrations, is a boost — but the headlines belie the costs incurred and the challenges involved.”  — Mike Hawes, SMMT chief executive

For leasing operators, the 36% deterioration in future margin confidence reported by BVRLA members in early 2026 tells the real story. The industry is growing in volume while being squeezed on returns — a combination that demands strategic clarity, not just optimism.

CHAPTER 2

Salary sacrifice: the silent revolution

If one number defines the UK's fleet market in 2025 and 2026, it is 125%. That is how much salary sacrifice volumes grew in 2025, reaching 226,663 cars — with 77% of Q4 2025 deliveries being electric. This is not incremental growth. It is a structural shift in how EVs reach UK roads.

The mechanics are straightforward, though the savings are striking. An employee exchanges a portion of their gross salary — before income tax and National Insurance are calculated — for the use of an electric company car. Benefit-in-Kind (BiK) tax on fully electric cars is just 4% of the vehicle's list price in 2026/27, rising to 5% in 2027/28, with increases legislated through to 9% by 2029/30. Compare that to 25–37% for equivalent petrol or diesel models.

 

+125% salary sacrifice growth in 2025

4% EV BiK rate 2026/27

20–50% employee saving vs personal lease

£9,000 typical saving over 3-year EV lease

 

A worked example makes the scale of advantage concrete. A 40% taxpayer leasing a Kia Niro EV on a three-year, 10,000-miles-per-year agreement through a salary sacrifice scheme would pay approximately £461 per month net — versus around £710 per month after tax on a standard personal lease. That is a saving of close to £250 every month, or £9,000 over the full term.

The Spring 2026 Statement confirmed no changes to EV BiK treatment or salary sacrifice rules, providing the policy certainty that multi-year lease agreements require. Leasing firms and brokers expect further expansion in 2026 — 70% of BVRLA members forecast increased demand from large corporates, with positive expectations also reported for SME customers.

 

WHAT MAKES SALARY SACRIFICE SO POWERFUL RIGHT NOW •    EV BiK at 4% vs up to 37% for high-emission petrol models creates an enormous built-in advantage •    Employees save on both income tax and National Insurance contributions simultaneously •    Schemes typically bundle insurance, maintenance, tyres and breakdown cover in the monthly cost •    Salary sacrifice is exempt from Optional Remuneration Arrangement (OpRA) restrictions that limit other benefits •    The ZEV mandate creates structural pressure on manufacturers to support fleet and salary sacrifice pricing

 

For leasing firms, salary sacrifice has become the growth engine that offsets pressure on personal contract hire. The challenge is managing the end of those salary sacrifice contracts — when a wave of nearly-new EVs returns to the market and residual values become the critical test.

CHAPTER 3

EVs vs PHEVs — not a contest, a portfolio

One of the most common mistakes in discussions about the UK car market is treating EVs and PHEVs as rivals. They are not. In 2026, they are complementary instruments in a leasing portfolio — each with distinct strengths, risks, and customer profiles.

The data from March 2026 registrations illustrates this clearly. PHEV registrations grew 46.9% year-on-year, outpacing even BEV growth of 24.2%. Hybrid (non-plug-in) registrations rose 7.3%. The market is not converging on one solution — it is diversifying.

 

+46.9% PHEV registration growth, March 2026 YoY

+24.2% BEV registration growth, March 2026 YoY

64% of leasing firms expect EV RVs to fall further in 2026

77% expect ICE residual values to hold or improve

 

The EV case is strongest where it has always been strongest: salary sacrifice, corporate fleets meeting CO2 targets, urban drivers benefiting from ULEZ exemptions, and premium segments where residual values hold better. The BYD Seal, MG4 EV, and Tesla Model 3 all carry genuine fleet credentials.

But the residual value problem is real and it is worsening. Nearly two thirds of BVRLA member companies expect used EV values to decline again in 2026. The losses from the first wave of fleet EVs returning to the used market have been significant — and they have directly eroded the margin confidence of leasing operators.

“Persistent pressure on electric vehicle residual values, combined with wider economic uncertainty, means margins are being squeezed like never before.”  — Toby Poston, BVRLA chief executive

PHEVs tell a different story. Their residual values are more stable, their customer base is broader (including high-mileage drivers, rural users, and those without home charging), and their 46.9% registration growth suggests demand is accelerating rather than plateauing. BiK rates of 5–14% depending on electric range make them tax-efficient for company car drivers, without the full exposure to EV residual value risk.

For leasing firms, the implication is a portfolio approach rather than a binary choice. A mix weighted towards EVs for salary sacrifice and corporate accounts, with a meaningful PHEV allocation for SME fleets and higher-mileage users, reflects where demand actually sits in 2026.

CHAPTER 4

Chinese brands: from curiosity to category

Three years ago, spotting a BYD on UK roads was a rare event. Today, Chinese brands account for nearly 10% of all new UK vehicle registrations — and their market share doubled within a single twelve-month period. This is not a trend that is building. It has already arrived.

The most dramatic individual story is Jaecoo. The Chery-owned brand, which launched in the UK in January 2025, saw its market share rise from 0.56% in Q1 2025 to 3.08% in Q1 2026. The Jaecoo 7 was the single best-selling model in the entire UK market in March 2026, with over 10,000 registrations in that month alone. Since its February 2025 launch, 41,952 Jaecoo 7s have been sold in the UK.

 

EV + PHEV BYD World's largest EV manufacturer. 51,000 UK sales in 2025 (+567% YoY). 130+ UK dealerships. 7-year vehicle / 8-year battery warranty.	EV + HYBRID MG Motor UK's most established Chinese brand. 153 dealer locations. 3.88% market share Q1 2026. Most accessible Chinese EV entry point.	PHEV LEADER Jaecoo Chery-owned. Launched January 2025. Jaecoo 7 was UK's top-selling model in March 2026. 41,952 units sold since launch.
EMERGING Omoda Also Chery-owned. Growing share in early 2026. Omoda 5 was a top salary sacrifice car in 2025. PHEV range expanding with Omoda 7 and 9.	EV Xpeng Tech-focused. G6 holds five-star Euro NCAP. Rapidly scaling UK presence. Strong ADAS credentials.	INCOMING Denza (BYD) Premium BYD sub-brand. Expected UK launch mid-2026. Targeting £50,000–75,000 segment with Z9 GT EV and B5 PHEV.

 

The safety question — once a genuine objection — has effectively been answered. Euro NCAP has awarded five stars to the BYD Seal, BYD Atto 3, Xpeng G6, and MG4 EV, with the MG4 receiving particularly high scores for adult occupant protection. BYD's Blade Battery, using lithium iron phosphate (LFP) chemistry, has a projected lifespan exceeding one million miles and is widely regarded as one of the safest battery architectures available.

The PHEV opportunity is especially striking. In February 2026, Chinese brands held 15% of the UK PHEV market for stock under one year old. One in every three enquiries for a PHEV now goes to a Chinese manufacturer. The BYD Seal U DM-i became the sixth-biggest-selling car in the UK in September 2025, with 5,373 units in a single month.

For leasing firms, Chinese brands present both an opportunity and a risk to price carefully. Their lower list prices translate to lower monthly sacrifice amounts — compounding the tax savings in salary sacrifice. But residual value data is still thin for newer entrants, and depreciation on Chinese EVs has run at 35–50% after three years versus 25–35% for Tesla. The established names — BYD and MG — now have enough UK history to model more confidently. The newer arrivals require more caution.

CHAPTER 5

The residual value reckoning

Every leasing contract is, at its core, a bet on the future value of a vehicle. The monthly payment a customer sees reflects the gap between what the leasing company pays for the car and what it expects to recover when the contract ends. Get the residual value wrong, and the loss is borne by the lessor.

That is why the BVRLA's finding — that 64% of leasing firms expect used EV values to decline again in 2026 — is not just an industry statistic. It is the central commercial problem of the sector right now. Used electric car prices were still falling in early 2026, with average values down nearly 10% year-on-year. The strong disposal profits that leasing firms enjoyed in 2022 and 2023 have gone.

 

THE RESIDUAL VALUE CHALLENGE — WHAT'S DRIVING IT •    Tesla's aggressive list price reductions have reset pricing expectations across the EV segment •    A wave of early-fleet EVs returning to the used market is creating supply-side pressure •    Consumer confidence in used EV battery health remains a barrier — reducing demand at the prices needed to protect margins •    Chinese EV depreciation is running faster than established brands, at 35–50% over three years vs 25–35% for Tesla •    BiK is calculated on a vehicle's list price when new, even for used car salary sacrifice — creating a structural barrier to used EV adoption via salary sacrifice

 

ICE vehicles, by contrast, are holding their value. 77% of rental and leasing companies expect ICE residual values to remain stable or improve in 2026. PHEVs also offer more predictable depreciation curves. This creates a perverse dynamic: the segment most incentivised by tax policy (EVs) is the segment creating the most margin pressure for leasing operators.

The BVRLA has called for government intervention — including grants to support used EV pricing and a reform of BiK rules for used car salary sacrifice, so that tax is calculated on the vehicle's current value rather than its original list price. Without movement on these points, the used EV market will continue to be an uncomfortable space for leasing operators to manage exits.

For firms building their risk models, the credible tools are a combination of CAP HPI data, Glass's Guide valuations, internal fleet disposal history, and — increasingly — data from the emerging market in battery health certification. Lenders and leasing companies that can accurately score battery condition will have a material advantage in pricing used EV risk.

CHAPTER 6

What comes next

The UK car market is not in transition. It has already transitioned. The question now is which leasing firms, OEMs, and fleet operators are positioned to turn that reality into sustained commercial performance — and which are still hoping the old model comes back.

Salary sacrifice will keep growing. 70% of BVRLA members expect increased demand from large corporates in 2026. The legislative clarity provided by the Spring Statement removes a major barrier to long-term commitment. Firms that have not yet built dedicated salary sacrifice infrastructure — policy frameworks, payroll integration, NMW compliance systems — are increasingly at a disadvantage to those who have.

The ZEV mandate will continue to create pressure and opportunity simultaneously. The 2026 target of 33% BEV market share will be missed in headline terms, but the double-counting of electric vans and banked flexibilities from prior years will give most manufacturers room. The trajectory toward the 2030 80% target, however, is non-negotiable — and it will require a step change in consumer-facing EV adoption that salary sacrifice and corporate fleets alone cannot deliver.

Chinese brands are not going away. They are going upstream. BYD's Denza sub-brand is expected in the UK by mid-2026, targeting the £50,000–75,000 premium segment with an EV sports estate and a PHEV SUV. The Jaecoo 7's position as the UK's best-selling car in March 2026 would have been considered impossible fiction two years ago. Leasing firms that engage with these brands on residual value modelling — rather than waiting for the market to mature before acting — will capture margin advantage earlier.

 

THE LEASING FIRM PLAYBOOK FOR THE NEXT 12 MONTHS •    Build salary sacrifice infrastructure if you haven't — this segment is growing regardless of the personal lease market •    Treat PHEV as a genuine portfolio category, not a transitional compromise — 46.9% growth is a signal, not a footnote •    Invest in used EV battery health data to price residual risk more accurately than competitors •    Selectively integrate Chinese brands — BYD and MG have enough UK history to model; newer entrants require conservative RV assumptions •    Watch the ZEV mandate flexibilities carefully — they create short-term pricing dynamics that fleet teams can exploit •    Push BVRLA and government on BiK reform for used car salary sacrifice — it is the unlock the used EV market needs

 

The algorithmic car market is not a metaphor. Pricing, residual values, BiK rates, mandate compliance credits, and salary sacrifice tax calculations all interact in real time to determine who wins and who absorbs losses. The firms that treat this as a data and modelling challenge — not just a sales challenge — are the ones building durable advantage in 2026 and beyond.
