Key facts
- The main barrier to electric vehicle (EV) adoption in the UK is affordability, not availability.
- Around one-third of UK households lack off-street parking.
- Charging at home costs about 7p/mile, versus 26p/mile using ultra-rapid public charging.
- Public charging attracts 20% VAT, while domestic electricity is taxed at 5%.
- Energy costs at rapid and ultra-rapid charging sites have risen 79% since 2021.
- Network charges have increased by approximately 300% and standing charges by 462% since 2021.
The primary obstacle to electric vehicle (EV) adoption in the UK is no longer the availability of charging infrastructure, but rather the cost, according to Ian McKee, head of communications for the industry group ChargeUK. Operators are continuing to build out charging points, often ahead of projected demand, but drivers who cannot charge at home face significantly higher expenses.
While concerns about charger availability were prevalent several years ago, the public charging network has approximately doubled in size over the past three years. Research indicates that provision for near-home charging is about 1.5 years ahead of projected demand, and motorway charging is even further ahead, approximately six years. However, the pace of rollout needs to accelerate to maintain this lead, with an estimated 110,000 more near-home chargepoints required by 2030. Households without driveways remain less well-served, with only 23% within a short walk of a public charger.
The cost disparity between home charging and public charging is substantial. Charging an EV at home costs approximately 7 pence per mile, whereas using ultra-rapid public chargers can cost around 26 pence per mile. This difference is exacerbated by a 20% value-added tax (VAT) on public charging compared to 5% on domestic electricity, costing drivers without home charging an estimated £145 annually. The industry's main cost concerns are not hardware or wholesale electricity prices, but rather network and standing charges, which have seen significant increases since 2021. Energy costs have risen by 79%, network charges by around 300%, and standing charges by 462%.
The charging sector argues that it has largely invested ahead of demand and now requires increased EV uptake to catch up. Analysis commissioned by ChargeUK suggests the sector could attract nearly £30 billion in investment by 2035, contingent on the UK's zero-emission vehicle mandate providing confidence in future EV demand. Weakening this mandate could reduce future charging investment by £1.5 billion to £2 billion, disproportionately affecting less commercially attractive regions.
Data from Zapmap shows that while the number of UK public chargers increased by 13% in 2025 and electricity delivered rose by 21%, charger utilization remained largely unchanged. Ultra-rapid chargers were occupied only about 13% of the time, despite a 40% increase in their numbers. This suggests operators are still building ahead of demand, and the focus for the industry is shifting towards EV adoption rates, utilization, and policy support, with the question for many drivers becoming whether public charging can become affordable enough to rival home charging.
