Where Public Charging Prices Stand Going Into Autumn

Public charging prices have been remarkably stable through the summer, and that stability is itself the story. While the network behind the prices keeps expanding, the amounts drivers actually pay per kilowatt-hour have barely moved since spring, which makes this a sensible moment to take stock of what charging costs, where the price spread sits, and how a driver who plans even slightly can pay meaningfully less than the headline rates.

The numbers as they stand

Using Zapmap's price index, built from close to four million charge sessions a month, the July averages are these: around 54p per kWh on standard and standard-plus chargers, the 3kW to 49kW tier that covers most destination and on-street charging, and around 79 to 80p per kWh on the rapid and ultra-rapid PAYG rates you pay at motorway-style sites without a membership or subscription. Zapmap's own rapid price tables show the spread between networks remains wide, with PAYG rapid prices running from the high 50s to the high 80s depending on the operator.

Turn those kilowatt-hour prices into miles and the picture gets practical. At an efficient 4 miles per kWh, 54p standard charging works out near 13p per mile, rapid PAYG near 20p, against a typical petrol car at roughly the same cost per mile once fuel duty is counted. The home-versus-public gap is where EV economics still win: charge overnight on an EV tariff at 7p to 8p per kWh and the same mile costs about 2p.

Three ways drivers pay less than the headline rate

The PAYG price is the worst price on the network, and it is the one quoted most often. Drivers who use public charging regularly bring that number down in three ways.

The first is network memberships. Most major operators sell a monthly subscription that shaves a fixed amount off each kWh, and for anyone rapid-charging more than two or three times a month the maths usually lands in the member's favour. The second is contactless and app rates, which several networks now price below their PAYG headline as competition for drivers intensifies. The third is location discipline: the same kilowatt-hour can cost 20p less a few minutes off the motorway, and the state of the charging network makes those detours increasingly viable, with more than 121,000 public charge points now live across the country and the fastest growth happening in the cheaper destination tier rather than at premium rapid sites.

Why prices are flat while the network grows

You might expect a network growing 10% a year to produce falling prices, and you might expect the opposite, given the capital cost of hardware. What actually happens is both at once. Competition between operators is real and intensifying, which pulls published rates down at the margin, while grid connection costs, maintenance and the sheer expense of ultra-rapid hardware push the floor back up. The net effect through 2026 has been a plateau: standard charging steady around the mid-50s per kWh, rapid PAYG oscillating within a few pence either side of 80p.

For context on where this sits internationally, independent comparisons keep finding the UK among the more expensive countries in the world for DC fast charging, which is the honest cost of a network built quickly by private capital at commercial rates. The direction of travel that matters for drivers is not the national average, it is the spread: as more operators compete for the same drivers, the gap between a thoughtless charge and a planned one keeps widening.

Three drivers, three different outcomes

The clearest way to see the spread is to follow Zapmap's own driver profiles, which turn the averages into annual bills.

A driver with a driveway and an off-peak tariff, charging almost exclusively at home at around 8.6p per kWh, pays roughly a quarter of the national average cost per mile and barely notices the public network except twice a year on long trips. A mixed driver, home most weeks with monthly motorway runs on rapid chargers, lands somewhere near 8 to 10p per mile all-in, still comfortably below petrol. The third profile, the driver with no home charging who relies on rapid and ultra-rapid PAYG for everything, pays close to the full 24p per mile that the 80p per kWh rapid rate implies, which at typical mileages approaches petrol territory.

The lesson in those three columns is that the public network's headline price is a ceiling, not a bill. Almost nobody pays it all the time, and the practical difference between the first profile and the third is worth several hundred pounds a year, which is more than most cars lose to depreciation in a month.

The practical takeaway

If you charge at home, none of this changes your life: the home charging route remains roughly a quarter of the cost of the motorway rapid. If you depend on the public network, the July data says your costs are stable and your savings are in your own hands, a membership here, a destination charger there, and a habit of checking two apps before plugging in. Charging an EV is already cheaper than fuelling a petrol car for most drivers; keeping it that way on the road is mostly a planning exercise now rather than a price-watching one.

The Autumn Budget will tell us whether the government adds anything to the demand side, and October brings the closure of the mandate review, whose outcome will shape discounting and therefore the effective price of going electric. Between now and then, the tracker's message is simple: prices are flat, the cheap end of the network is growing fastest, and the driver with a plan pays a fraction of the driver without one.
