One in three public EV chargers in UK deliver inaccurate energy readings, industry study finds
By Eve
Independent inspection specialist EVCI Global tested hundreds of public EV chargers in real world use and found that 31.5% delivered energy readings that did not match the actual amount supplied. While UK regulations permit EV chargers a tolerance of up to +2% (compared to -0.5% to +1% for fuel pumps), nearly one third of chargers tested fell outside these standards. The findings raise concerns that drivers may be paying for electricity they do not receive.
Why it matters
Metering inaccuracy at scale undermines trust in public charging infrastructure and may expose charge point operators to regulatory scrutiny or commercial disputes. Procurement teams and site hosts should verify that equipment meets statutory tolerances and consider independent testing protocols before deployment.

RAC Warranty extends battery failure coverage to 12 years or 80,000 miles on EV One policy
RAC Warranty has extended its battery failure coverage to 12 years or 80,000 miles on its EV One policy, which applies to EVs, plug-in hybrids, and mild hybrids. RAC dealers can sell cover for up to 48 months, with the claim limit set at the vehicle's purchase price and replacement batteries guaranteed to match the original unit's energy capacity. During the first six months of 2026, RAC Warranty sold more EV policies than in the whole of 2025.
Why it matters
Extended warranty coverage addressing battery longevity concerns may reduce total cost of ownership barriers for fleet operators and corporate buyers evaluating EV procurement. The policy's growth signals rising confidence in the used EV market, potentially expanding the addressable customer base for charging infrastructure providers.
Believ to install more than 600 chargers across Ayrshire in 15 year council partnership
EV charge point operator Believ has secured a 15 year agreement with three Ayrshire councils to install more than 600 chargers at around 300 locations, with installation beginning in early 2027. The project combines over £2.8m from the Scottish Government's EV Infrastructure Fund with more than £15m in committed capital investment from Believ, delivered alongside Transport Scotland and the Scottish Futures Trust. The rollout includes roughly 180 chargers for East Ayrshire, 210 for North Ayrshire and 220 for South Ayrshire, with passive infrastructure for over 450 additional chargers to enable future upgrades without disruptive roadworks.
Why it matters
This major regional deployment demonstrates how CPOs can secure long term public sector contracts by combining government funding with substantial private capital, creating a scalable model for rural and island charging access. The inclusion of passive infrastructure for 450 additional chargers shows forward planning that reduces future deployment costs and speeds network expansion as EV adoption grows.
Vietnam mandates cross-brand compatibility at public EV chargers from July 2027
Circular 61/2026/TT-BCT, issued by Vietnam's Ministry of Industry and Trade, requires public EV charging stations to serve vehicles from multiple manufacturers starting 1 July 2027. Operators must install compatible connectors, charging modes and technical specifications, and station control systems must not restrict charging for publicly declared compatible vehicle configurations. The regulation emphasises technical compatibility without mandating support for all vehicle brands, The Investor reported on 8 October.
Why it matters
The rule forces charging point operators in Vietnam to design infrastructure for interoperability, potentially raising upfront costs but widening the addressable customer base. Procurement teams and OEMs will need to verify that hardware and software meet the new compatibility standards ahead of the July 2027 deadline.
