Transport for London has opened a consultation on making London's private hire fleet zero emission. Under the plans, any standard private hire vehicle (PHV) licensed in London for the first time would have to be fully electric from 3 July 2028. Wheelchair accessible PHVs would get more time, with the same rule starting on 1 July 2030, so that makers have a firm deadline to build accessible electric models. TfL also wants other changes from 1 March 2027. It would stop approving new LPG and CNG fuel conversions and new exhaust clean-up systems. If a licensed vehicle's licence runs out, the owner would have 12 months instead of 24 to relicense it before it is treated as new to licensing. A further proposal would stop PHVs staying licensed once they reach 10 years old. TfL says more than 70% of London PHVs are already zero-emission capable, but those that are not fully electric still give off exhaust fumes when the engine is running. It expects the plans to cut PHV carbon dioxide emissions by 35% over the first ten years. The consultation closes at 23:59 on Wednesday 2 December 2026. A zero-emission rule for London taxis is still being considered separately.
