Three-quarters of the UK's 20 most popular plug-in hybrid electric vehicle models cannot use rapid chargers rated at 50kW or more, according to analysis by the industry body ChargeUK.
The analysis found that only 26% of vehicles sold across those 20 models are capable of using rapid charging at 50kW or above. Rapid chargers are increasingly important for drivers making longer journeys because they can replenish a compatible vehicle's battery considerably faster than conventional public chargers.
The findings have renewed debate over the practical role of plug-in hybrid electric vehicles (PHEVs), which combine a rechargeable battery and electric motor with an internal combustion engine.
PHEVs are designed to offer drivers the option of using electric power for shorter journeys while retaining a petrol or diesel engine for longer trips.
However, according to the ChargeUK analysis, several of the UK's popular PHEV models cannot take advantage of the faster public charging network.
The models included in the analysis include the Jaecoo 7, Ford Kuga and Hyundai Tucson. The BYD Seal, MG HS and BMW 3 Series are also among the top 20 models cited, with the source reporting that none of those three can use rapid chargers.
A vehicle's inability to use a rapid charger does not prevent it from being charged. Instead, drivers of affected models must use slower charging options or rely on the vehicle's combustion engine when travelling longer distances.
In the UK, rapid charging is generally defined as charging at 50kW or above, while ultra-rapid charging begins at 150kW.
The Department for Transport reported 28,887 public EV chargers rated rapid or above as of 1 July 2026. Overall, the UK had 121,171 public EV chargers at that point.
Rapid and ultra-rapid chargers are particularly useful for drivers travelling long distances because they can add substantially more energy in a shorter period than lower-powered chargers.
However, the charging speed a vehicle can accept depends on the car's own charging capability as well as the charger.
The charging issue comes as questions continue over the real-world environmental performance of plug-in hybrids.
The UK Government has previously acknowledged that research indicates PHEVs can be driven in electric mode less frequently than official calculations assume. Its policy documents note that the utility factor used to calculate official emissions can overestimate how often drivers use electric power, resulting in higher real-world CO₂ emissions.
Government testing has also included real-world assessments of PHEVs. The Driver and Vehicle Standards Agency tested models including the Ford Kuga, MG HS, Skoda Octavia, Suzuki Across and Vauxhall Astra as part of its vehicle emissions programme.
These findings do not mean that every PHEV produces the same emissions or performs identically. Actual emissions depend on factors including how frequently the vehicle is charged, driving conditions and how much of a journey is completed using electric power.
Despite the debate, plug-in hybrids have become an increasingly significant part of the UK new-car market.
The source analysis reports that about 227,000 PHEVs were registered in the UK during 2025, representing an increase of almost 35% compared with 2024. A further 180,000 had reportedly been sold during 2026 by the time of the report.
The increase has coincided with continuing debate over the Government's Zero Emission Vehicle mandate and the transition away from petrol and diesel vehicles.
The comparison with fully electric vehicles is also notable.
According to the analysis supplied by the Guardian, every one of the UK's 20 best-selling pure-electric models sold during the previous year could use rapid charging, while 64% could use ultra-rapid charging.
That does not necessarily mean every EV will charge at the maximum advertised speed. Charging performance can vary according to the vehicle, battery condition, temperature and the specifications of the charging point.
For PHEV owners, the availability of slower charging may be less significant if the vehicle is primarily used for shorter journeys and regularly charged at home. For motorists who depend on public charging during long journeys, however, the charging capability of a particular model can become a more important consideration.
The Government has defended the continued availability of plug-in hybrids as part of the transition towards lower-emission vehicles.
A government spokesperson said the Government was taking a practical approach by allowing drivers to choose PHEVs and said their real-world carbon emissions remained 40% lower than those of the average petrol or diesel car.
The debate is likely to continue as policymakers review the UK's vehicle-emissions rules and manufacturers balance demand for different types of electrified vehicles.
For motorists considering a PHEV, the latest analysis highlights the importance of checking not only electric driving range but also the vehicle's maximum charging rate and compatibility with public rapid-charging networks.
