Fleet electrification in 2026: The regulation and incentives driving changeStay ahead with this practical guide

By Mark Oxtoby, Founder Director of amphos.

The year 2026 is shaping up to be a turning point for fleet electrification. Not because of one headline policy, but because several regulations, grants and commercial pressures converge at the same time. Together, they will influence how confident fleet operators feel about committing to long-term decarbonisation plans.

For most operators, this isn’t about ambition but vehicle availability, compliance, cost control and delivery.

Here’s what’s really changing in 2026 – and why getting the detail right now can save time, money and disruption later.

1. The regulation quietly reshaping vehicle supply: the ZEV Mandate

The Zero Emission Vehicle (ZEV) Mandate doesn’t apply directly to fleet operators – but its impact absolutely does.

From the 2026 calendar year, manufacturers must ensure that:

· 33% of new car registrations are zero-emission

· 24% of new van registrations are zero-emission

This matters because it directly influences:

· Vehicle availability and lead times,

· OEM appetite for fleet deals,

· Pricing structures and contract flexibility,

· Which models are prioritised – and which quietly disappear.

This sits within the wider policy direction:

100% zero-emission cars and vans by 2035

For fleet operators who have previously delayed making decisions around electrification, well 2026 is where that thinking could start to unravel. Vehicle choice is likely to narrow, not widen, and early engagement with manufacturers and leasing partners becomes critical.

2. Vehicle purchase support: time-limited, model-specific, and still misunderstood

Plug-in Van & Truck Grants (PIVG / PITrG)

These grants reduce the upfront cost of eligible:

· Electric vans

· Certain electric trucks and HGVs

They are currently scheduled to run until 31 March 2026.

What often gets missed:

· Eligibility is model-specific,

· The approved list changes,

· Ordering, delivery and invoicing timing all matter.

If you are planning in early 2026, procurement timelines need aligning now. We regularly see fleet operators miss funding simply because paperwork or delivery dates didn’t line up.

Leasing dynamics: the quieter incentive

While not a government grant, the ZEV Mandate is already influencing:

· Residual Value assumptions,

· OEM-backed lease pricing,

· Contract availability for EVs versus diesel.

For fleet operators that lease rather than buy, this is becoming a material financial incentive. In some segments, electric vehicles are starting to offer more predictable long-term costs than diesel, purely because of how manufacturers are managing supply and risk.

3. Depot and workplace charging: where grants make the difference between “some chargers” and something that actually works

Two charging schemes remain open – and both close on 31 March 2026.

Workplace Charging Scheme (WCS)

· Voucher-based support for charge point installation

· Up to 40 sockets per applicant across multiple sites

EV Infrastructure Grant for Staff and Fleets (SMEs)

· Helps cover “make-ready” costs

· Cabling, trenching, distribution upgrades – the expensive, unglamorous work

For many operators, these grants are the difference between:

· Installing infrastructure that scales with the fleet, or

· Installing something that is outgrown almost immediately

2026 is a deadline year. Design, DNO engagement and land rights negotiations all take time, and you need an expert to manage them for you. Charging projects fail when planning starts too late.

4. Charging compliance rules that start to bite in 2026

Public Charge Point Regulations 2023 (UK-wide)

If any of your sites allow public access – even for limited hours – these rules may apply. They cover:

· Contactless payment

· Pricing transparency

· Open data requirements

· Reliability standards and helplines

Applicability depends on power rating and installation date, which is where many operators get caught out.

Smart Charge Points Regulations (Great Britain)

For private workplace chargers, new units sold must meet smart functionality requirements (with limited exceptions). This affects:

· Which hardware you are allowed to install

· How chargers operate

· Future flexibility and optimisation

Compliance isn’t optional but it is manageable if designed in from day one. Retrofitting later is where cost and frustration creep in. Supply chain disruption may impact equipment availability, so work with a specialist who can manage the process seamlessly.

5. Tax still favours EVs – but only if you structure things properly

100% First-Year Allowances (FYA)

· Extended into 2026/27

· Applies to qualifying zero-emission cars and charge points

· Particularly relevant for fleets that buy rather than lease

Vehicle Excise Duty (VED)

· EVs are no longer fully exempt

· Changes began in April 2025 and continue through 2026

· Operating cost models will need updating

Company Car Benefit-in-Kind (BiK)

· Still highly favourable for EVs through 2027/28

· Provides planning certainty for company car and salary-sacrifice schemes

The incentives are still there – but only if procurement, ownership and tax planning are aligned. This is where joined-up advice quickly pays for itself.

6. Energy costs: not a grant, but a real operational incentive

Electric fleets increasingly benefit from:

· Time-of-use electricity tariffs

· Smart charging that shifts load away from peak prices

· On-site energy management and solar integration

While they are not government incentives in the traditional sense, these mechanisms can materially reduce cost per mile and improve resilience against fuel price volatility. For high-mileage fleets, energy strategy is now as important as vehicle choice.

7. Local charges: the detail matters more than the headline

Clean Air Zones (CAZ)

· EVs typically avoid charges, but rules vary by city and vehicle class

· Registration and account setup are still required in many cases

London Congestion Charge (from 2 January 2026)

· Full EV exemption ends

· Replaced by tiered Auto Pay discounts:

o 50% discount for electric vans and HGVs

o 25% discount for electric cars

For multi-city fleets, assumptions are risky. Local policy differences can quietly undermine operating cost models if they’re ignored.

8. Infrastructure changes that indirectly support fleet electrification

Local Electric Vehicle Infrastructure (LEVI) Fund (England only)

· Supports local authority charging for drivers without off-street parking

· Particularly relevant for take-home vans

Reduced planning “red tape” (England only)

· From 29 May 2025, many chargers no longer require planning permission

· Speeds up delivery, but does not remove grid or land constraints

Bus-specific funding (where relevant)

· Programmes such as ZEBRA continue to support zero-emission bus deployment in certain regions

· Particularly relevant for public sector fleets and contracted operators

The takeaway:

2026 isn’t about a single decision. It’s about many small decisions lining up – or not.

Fleet electrification will reward operators who plan early, understand the detail and design for the long-term. Those who wait risk higher costs, fewer choices and avoidable disruption.
