How Modern Cities Are Solving the EV Charging Dilemma for High-Density Housing

EV Charging

Last Updated on July 24, 2026 by Surender Kumar

Too much of the electric vehicle discussion was about the technology and the car, and not enough was about where people live. For the suburban homeowner with a garage and a bit of driveway to park the vehicle, the charging issue could be resolved. For the renter in a fourth-floor flat or the family living in a terraced row of houses with no private parking, it remained an intractable question; and only now are cities beginning to grapple with its scale.

Why High-Density Housing is the Hardest Part of the Transition

The EV transition has an equity problem baked into its infrastructure. The cheapest, most convenient form of charging, overnight, at home, requires that you have a private parking space. About 40% of UK households don’t have access to off-street parking. In dense urban areas, more than 60% don’t. That’s not a marginal edge case. That’s most residents in most major cities.

For apartment, flat, and condominium dwellers, the problem goes beyond simply needing a plug in the car park. The main electrical panels in multiunit dwellings constructed before 2000 typically weren’t designed for that demand. Retrofitting an apartment block for EV charging requires going through the building’s shared electrical infrastructure to increase the total power supply. That’s a long, expensive process, and it can be held up by a single member of the building’s shared ownership structure. A single 7kW charger running overnight is relatively easy. Twenty of them running at the same time isn’t.

For flat dwellers, landlords historically controlled whether someone could install a charging point, often citing liability or building management concerns. Right to Charge legislation is starting to eliminate that veto, but it doesn’t solve the problem of getting the physical infrastructure in place. It just removes the bureaucratic part of the process.

Regional Blueprints and Neighbourhood-Scale Networks

The most successful implementations are not rolled out across the whole city at once. They are implemented step by step, with local authorities working with Charge Point Operators to create a dense network tailored to a specific postcode to ensure residents feel safe enough to switch to EVs despite not having driveways. It has become much easier to find reliable, high-density public infrastructure like ev charging in manchester, as regional operators deploy denser networks rather than offering limited coverage across the entire city.

The model at the neighbourhood level is important, as the adoption of electric vehicles is also a social confidence issue. People won’t switch until they believe the infrastructure will be in place when they need it. A single charger in front of a street won’t generate that confidence. On the other hand, a visible, reliable cluster of options within walking distance begins to change this attitude.

Cities that are succeeding are considering this less of an infrastructure issue and more of a service design problem and are wondering where people actually park, when they park, for how long, and what kind of slow overnight and rapid charge combination is right for those scenarios. The solution will be different for residential streets from the Victorian era than for 1990s apartments, and the details are what differentiate successful deployments from underutilized ones.

Drivers who don’t have a driveway are not a special circumstance. They constitute the bulk of urban dwellers, and the first cities to find charging solutions for them will have an important lead for every later development.

How Smart Charging Buys Time on the Grid

A more feasible solution to grid pressure in locations with high population density in the near future would be load balancing, also known as smart charging in the industry. Instead of each charger pulling at maximum capacity at the same time, the system balances the power and charges all connected vehicles based on their current state of charge, user-defined priorities, and grid limitations.

This means that in practice, an apartment block with a 100kW supply can in theory “share” that power with 30 or 40 vehicles overnight, because the system knows that none of those cars will be empty and be therefore asking for a full charge, and that the charging can be spread over an 8-hour window. The driver sets a departure time and the software pulls only what they need at the time when it costs the least.

Vehicle-to-grid takes this a step further, allowing electric vehicles to also push electricity back into the building or local grid during peak times, effectively turning a parking lot full of batteries into a temporary storage asset. It’s not yet widely used, but the architecture is being integrated into new charger deployments specifically because planners predict they’ll want the capability in the next five years or so.

Kerbside Innovation For Streets Without Driveways

Terraced housing streets are a different problem. There’s no car park to retrofit. The car just sits on the street, often 10 to 15 metres from the front door. Running a cable across the pavement might be simple, but it’s also an obvious tripping hazard and quickly becomes a liability problem the moment someone falls over it.

Cities have mostly been trialling two approaches. The first are cable gulleys, shallow in-pavement channels with a hinged or recessed cover that allows a cable to run flush with the surface from house to car. Several boroughs have tested these, and the results are mixed: they work reasonably well on wider pavements, but create access problems for wheelchairs and mobility aids on narrower ones.

The second approach is lamppost charging retrofits. Existing street lighting already has an electrical connection to each post, and the technology to add a low-power charging outlet to that infrastructure is relatively straightforward. The result is a charger that adds nothing to pavement clutter because the post was already there. Power output is typically capped at 3kW to 5kW, which is slower than a dedicated home unit, but for a car that sits on the street all night, it’s usually sufficient for daily use.

Neither solution is perfect. But both of them represent a broad shift away from the assumption a decade ago that every public charging point needed to be a large freestanding pedestal.

The Ultra-Rapid Hub as a Weekly Errand

A new pattern of behavior is becoming common in high-density urban environments and it doesn’t resemble home charging. Instead, it looks like a petrol station. For customers in flats or terraced housing with no off-street parking, charging is increasingly becoming a weekly errand. They’ll pop in to an ultra-rapid hub, grab 150 to 200 miles of range in 20 to 25 minutes, and be on their way.

Ultra-rapid chargers at 150kW and above can support this. The time cost of a weekly charge is low enough at that speed that it ceases to be an inconvenience and becomes a habit. But that only works if there are enough hubs in the right locations. One hub serving three postcodes doesn’t cut it. It has to be dense enough that it feels like petrol station distribution, you’re never more than a short drive away.

That’s where the bulk of Charge Point Operator investment is going. The economics of ultra-rapid hubs are better than those of slow public chargers. Utilisation rates are higher and the revenue per session is many times larger. That drives network density in a way that subsidy programs alone don’t.

Planning Codes and the Developer Mandate

The most cost-effective time to install EV charging infrastructure in a building is during the initial construction. Running conduit through a poured concrete slab costs almost nothing at the time of the pour. Cutting back through it five years later to retrofit wiring costs a great deal. This simple concept is behind a wave of building code changes updating the rules under which EV-ready conduit and panel capacity must be added by developers to new residential buildings even if the actual chargers aren’t fitted immediately.

This is not a wild west concept, it’s all codified in Part S Building Regulations in the UK, and equivalent legislation elsewhere. The result of these newer codes isn’t that every resident gets to immediately use an EV charger, you end up with a building that can easily add that charging in five years without a major engineering project. Which is a subtly different outcome from rules as they stood five years ago, which were essentially resulting in an entire generation of new-build apartment blocks built with absolutely no provision for EV charging.

Forward-thinking developers go a bit further than the rules require. It’s certainly not a new idea to treat EV charging as a selling point, and many developers simply choose to spend the relatively tiny amount extra it costs to connect their new development to the grid properly and put chargers in at day one. In some urban markets, particularly rentals, it’s becoming a major differentiator.

Workplace and Retail Charging as a Pressure Valve

One aspect of high-density charging that is often overlooked is daytime charging away from home. Destination charging, be it at offices, gyms, supermarkets, or retail parks, effectively takes the pressure off the residential grid by shifting some of the charging load to times and places where capacity is less of an issue.

A commuter who charges for three hours at their workplace car park leaves the office with a car that doesn’t need charging that night. This means one less vehicle adding to the evening peak demand on the residential network. Again, this doesn’t solve the problem, but it certainly makes it easier to manage. Retailers are already beginning to cotton on to this. Supermarkets and shopping centres, in particular, are increasingly installing charging infrastructure and offering free electricity to customers in the knowledge that if someone’s car is happily sucking power on one of their bays, they’ll be in the shop for half an hour or more, and they’re likely to spend more on groceries than they would have done otherwise. It’s a good business decision that also happens to interact positively with the EV infrastructure deficit
