Zero Emission Buses Pick up Record Share of Stalling Market

Why It Matters

The surge in zero‑emission bus share signals rapid decarbonisation of public transport, but the lag in zero‑emission trucks threatens broader emissions targets, highlighting the need for policy and infrastructure support.

Key Takeaways

• Zero‑emission buses captured 37.3% of UK market Q1 2026.
• Overall bus registrations fell 37.7% YoY, driven by minibuses.
• Local‑authority pipeline shows 23,381 ZEB deliveries by 2035.
• Zero‑emission HGVs represent only 0.9% of UK heavy‑goods fleet.
• Funding gaps and depot grid connections hinder wider ZEV adoption.

Pulse Analysis

3% share of registrations in the first quarter of 2026. This milestone follows a 2025 surge driven by the Zero Emission Bus Regional Area (ZEBRA) grants and similar Scottish ScotZEB incentives, which lifted registrations by nearly 50% in a single quarter. 7% year‑on‑year, the resilience of zero‑emission models underscores manufacturers’ heavy investment and the growing appetite of local authorities for cleaner fleets.

5% in Q1. Operators cite steep upfront costs, limited charging infrastructure at depots, and tight logistics margins as primary obstacles. The SMMT’s Plug‑in Truck Grant and Depot Charging Scheme aim to offset capital outlays, yet grid connection delays and a fragile economic backdrop continue to suppress demand, risking the sector’s ability to meet the 2040 ZEV mandate.

Looking ahead, the SMMT forecasts a pipeline of 23,381 zero‑emission bus deliveries through 2035, suggesting sustained growth if funding mechanisms and depot electrification keep pace. Policy makers are urged to fast‑track grid upgrades and expand grant programmes to bridge the infrastructure gap, while manufacturers expand model ranges to improve economies of scale. For investors, the divergent trajectories of buses and trucks present both opportunity and risk: bus fleets offer near‑term revenue streams, whereas the HGV segment may reward early‑stage capital once systemic barriers are removed.
