The UK’s pioneering electric fire engine, proudly unveiled by London Fire Brigade (LFB) in 2022, has yet to be used in a single real-life incident, it has emerged, despite promises it would be deployed on the frontline within its first year.
The vehicle, dubbed ZEPA1 (Zero Emission Capable Pumping Appliance), remains a trial piece of kit, now entering its third year without attending even a false alarm — let alone a fire.
“Developing zero emission solutions for fire engines presents unique challenges…” – LFB Spokesperson
Despite clocking up headlines and featuring in green-energy campaigns, the futuristic fire engine has yet to see action. Confirmations from both the London Fire Brigade and firefighters at Hammersmith Station, where ZEPA1 is based, have revealed it’s never been mobilised — not for a fire, nor even for a stranded feline.
What Is ZEPA1?
- Launched: 2022
- Battery capacity: 280kWh
- Range: 200 miles
- Water capacity: 1,750 litres
- Foam capacity: 100 litres
- Back-up engine: Petrol-powered “range extender”
Why Hasn’t It Been Used?
Multiple issues appear to have stalled the rollout:
- Charging infrastructure: A 150kW charger was supposedly installed at Hammersmith, but staff on-site appeared uncertain of its whereabouts.
- Training delays: The vehicle is currently undergoing upgrades to align with new breathing equipment, delaying rollout further.
- Unproven tech: Concerns remain that electric tech may not yet meet the rigours of high-pressure fire response operations.
According to LFB, the engine is still being “proactively tested” and learnings are being shared with other UK fire services. Yet ZEPA1 remains firmly in trial mode.
Still No Callouts
Since 1 January 2025, Hammersmith crews have responded to over 1,150 incidents, none of which involved ZEPA1.
A Symbol of Promise, or Taxpayer Waste?
The initiative’s original plan included ZEPA1 being “shadowed” by a diesel fire engine on real jobs during its first year. That never happened.
With zero real-world use and little public update, questions grow over the cost and true readiness of the electric fire engine — especially as Emergency One, the supplier, declined to comment on current performance or any ongoing issues.
Some Progress on Fleet Electrification
Not all green targets have been missed. LFB confirmed it has met its goal of converting all officer vehicles to electric by 2024, with VW ID.3s now part of the fleet.
Where Does This Leave ZEPA1?
As EV technology rapidly evolves, the ZEPA1 might soon be outpaced by newer innovations before it even hits the road. A frank assessment from LFB and City Hall is now overdue, with transparency on the vehicle’s future and a formal progress report essential.
When approached for comment, the Mayor of London’s Office declined to respond.
