The UK’s decarbonised transport transition is a structural shift for the automotive sector and corporate fleets. The Zero Emission Vehicle (ZEV) Mandate Review Consultation was published in August 2026. This gives fleet operators a critical juncture to reassess their procurement and operational strategies. Commitments to phase out new petrol and diesel cars by 2030 remain steadfast. The mandate for 100% zero-emission new vehicle sales by 2035 also stands firm. However, the consultation acknowledges complex market dynamics. These changing dynamics will require careful commercial navigation.
Understanding the August 2026 ZEV Mandate Review
The ZEV Mandate essentially forces vehicle manufacturers to sell a specific, increasing percentage of zero-emission vehicles each year. However, things haven’t grown quite as quickly as the government first hoped. While the electric car market share reached an impressive 24.2% of new cars by mid-2026. Van uptake is lagging significantly behind at around 11%.
Because of this slower-than-expected uptake, the UK, Welsh, Scottish, and Northern Irish Governments are jointly reviewing the mandate to ensure it remains ambitious but deliverable. They are consulting on potentially adjusting the interim targets for manufacturers before 2030. Whilst also keeping the ultimate 2030 and 2035 phase-out dates firmly in place.
Key Takeaways from the Consultation
- Target Adjustments: The government is considering lowering the 2030 ZEV targets for manufacturers. We might see car targets drop from 80% down to 50-70%, and van targets decrease from 70% down to 40-60%.
- Charging Infrastructure Growth: The UK charging network is expanding. There are now over 120,000 public chargers, with an average of 30 new public chargers being installed every single day.
- Manufacturer Flexibilities: So far, manufacturers have been relying heavily on flexibilities. These include borrowing, banking credits, and converting CO2 savings, to hit their targets rather than purely relying on sales alone.
What the ZEV Mandate Means for Your Fleet Strategy
Even if the government tweaks the interim targets for manufacturers, the direction of travel for fleet managers is clear. Fleet operators must adapt to a changing vehicle market, as the economics and availability of traditional vehicles are shifting rapidly.
The Squeeze on ICE Vehicles (2028-2030)
Manufacturers are facing rising compliance costs for internal combustion engine (ICE) vehicles. To give you an idea of the scale, manufacturers were spending around £4,000 per traded ZEV allowance for cars in 2024 alone.
- This immense financial pressure will likely result in higher list prices. Also, increased lease rentals for standard petrol and diesel vehicles.
- You can also expect to see reduced discounting on ICE vehicles. With potentially longer lead times for the most popular commercial models.
- Fleet Action: To avoid future supply shocks and price inflation, review your procurement cycles now and begin adjusting your purchasing plans ahead of 2028.
The Changing Face of PHEVs
Plug-in Hybrid Electric Vehicles (PHEVs) have been a useful stepping stone for many fleets, but they are rapidly losing regulatory favour under the ZEV Mandate review.
- Recent evidence shows that real-world PHEV CO2 emissions are estimated to be around 3 to 7 times higher than official WLTP testing suggests.
- The government is proposing a strict technological definition for 2030: Mild Hybrid Electric Vehicles (MHEVs) will be banned, meaning only full hybrids will be permitted for sale until 2035.
- As flexibilities tighten, manufacturers may start deprioritising PHEV production, making them harder to source and potentially increasing their taxation risk.
- Fleet Action: Review your long-term vehicle needs. Avoid making long-term commitments to PHEVs (and certainly MHEVs) from 2027 onwards to mitigate future availability issues.
Evolving Commercial Supply Challenges
As highlighted by industry bodies like the Association of Fleet Professionals (AFP), securing the right vehicles for operational needs is currently a major hurdle. Whether you are managing fleets for local housing associations or coordinating rapid response units, ensuring you have the right vehicles on the fleet, without extensive delays, is a daily concern.
Market pressure is building. We are already seeing reports of manufacturers stipulating order quotas, meaning fleets ordering large volumes of traditional vans are being forced to alter their orders to help the manufacturer meet their legal ZEV Mandate targets.
Actionable Steps to Future-Proof Your Fleet
To navigate the ZEV Mandate effectively, fleet managers need to move beyond simple vehicle procurement and focus on rigorous operational planning:
- Infrastructure and Routing: Start assessing your operational bases and driver routes. Understanding exactly how and where your vehicles operate is critical to planning future procurement smoothly.
- Update TCO Models: With shifting vehicle prices and fluctuating lease rentals in a maturing market, your Total Cost of Ownership (TCO) models need constant updating to reflect the truest economic picture.
- Review Policy Flexibility: Ensure your fleet policies are adaptable. With vehicle availability changing, your policies need to accommodate different procurement lead times and operational realities.

FAQs About the ZEV Mandate
What is the ZEV Mandate?
The ZEV Mandate is a UK government regulation requiring manufacturers to sell a set, increasing percentage of zero-emission vehicles each year, leading up to a 100% zero-emission requirement for new cars and vans by 2035.
Are petrol and diesel cars still being banned in 2030?
Yes, despite the 2026 review, the UK government remains committed to phasing out the sale of new cars that rely entirely on internal combustion engines (including mild hybrids) by 2030.
How will the ZEV review affect PHEVs?
Because real-world emissions for PHEVs are much higher than official tests suggest, they are losing regulatory favour. Only full hybrids will be allowed for sale between 2030 and 2035, and manufacturers may produce fewer PHEVs as flexibilities tighten.
Why are commercial vans getting more expensive?
Manufacturers are facing heavy financial compliance costs for producing traditional ICE vehicles under the mandate. These costs are being passed down to fleets through higher list prices, increased lease rentals, and reduced discounting.
What is the biggest challenge for fleet procurement right now?
Procuring the right commercial vehicles remains a major challenge due to shifting manufacturer quotas, changing vehicle specifications, and fluctuating lead times driven by regulatory pressures.
