Charging in a building nobody wired for it
A residential block has one incoming supply that is already accounted for, a car park designed for cars that did not plug in, and residents who ask for a charger one at a time over several years.
Priced per port, per month · Billed on the ports installed
Shared capacity and an unfair bill
The electrical capacity in a residential building is shared, finite, and already committed to lifts, lighting, heating, and every flat in it. A charger per parking bay, each sized for its full rate, is a number the incoming supply was never going to meet — which is why so many blocks are told the answer is a grid upgrade and stop there.
Then there is the bill. Running resident charging through the building meter and recovering it in the service charge means every household without a car pays for the ones with one. There is no version of that spreadsheet that survives a residents' meeting.
Capacity shared, costs separated
The two problems are related: both are solved by the platform knowing which resident is drawing what, at which moment.
One supply, many bays
The site is given a limit and the platform shares it across the cars actually plugged in. Cars parked overnight in a residential block have hours to spare, which is exactly the case load balancing is best at.
Each resident pays for their own energy
A card on file, charged automatically per session, paid out to the building account. Nothing lands in the service charge and nobody without a car subsidises anyone with one.
A bay that belongs to someone
RFID cards and app accounts control who may start a session and where, so an allocated bay stays allocated and a visitor bay can still be opened to guests.
The manager sees this building only
Roles and permissions mean a managing agent, a landlord, and an operator each see their own scope. One account can run twenty buildings without any of them seeing the others.
What a residential retrofit usually looks like
Cars sit here longer than anywhere else on this site. Almost every decision follows from that.
- Charger type
- AC, and modest power per bay is fine A car parked from evening to morning does not need a large charger. Lower power per bay is what lets the same supply reach more bays.
- How many ports
- Start with the residents asking, wire for the ones who will The expensive part of the second phase is the cabling, not the units. Containment and capacity installed once, chargers added to it as demand arrives.
- Access model
- One account per resident, RFID or app Ties the bay, the session, and the bill to the same person, which is what makes billing individually possible at all.
- Pricing model
- Per kWh — at cost, or with a margin toward the installation A small margin is how a lot of blocks fund the retrofit without a special levy. It is a decision for the building, not for us.
The Platform plan, billed on the ports you install
A residential block is on the Platform plan, priced per port per month, whether residents are charged for their energy or not. Paid charging, Stripe payments, and per-site roles are in the base platform. Shared capacity is the one thing most buildings add: dynamic load balancing is a paid module, switched on per site and quoted as its own line, on the Platform plan — no move to Enterprise needed.
- Paid charging, so a resident's energy lands on a resident's card
- Dynamic load balancing, the paid module that makes more than a few bays possible on one supply
- Per-site roles, so a managing agent sees exactly one building
The per-port subscription is billed on the ports installed, so a block that adds bays in phases pays in phases. The revenue share applies only to public paid sessions, not to residents charging in their own bays.

Can each resident be billed individually?
Yes. Each session is recorded against the account that started it, charged to their card when it ends, and paid out to the building. Nothing touches the service charge, and residents without an electric car pay nothing.
The car park is on one meter — is that a problem?
Not for the platform: session energy is read from the charger, so allocation does not depend on separate meters per bay. It does matter for the hardware. Where local metrology rules apply to billing a driver per kWh — Eichrecht in Germany is the obvious one — the charger itself has to carry a calibrated meter. That is a specification decision made at the survey, before anything is ordered.
Do we have to upgrade the building's supply?
Often not. Load balancing exists precisely so that a building can run more bays than a naive worst-case calculation allows, and overnight parking is the most forgiving profile there is. Whether an upgrade is genuinely needed is what an electrical survey answers, before anyone commits.
Should each resident have their own charger, or should bays be shared?
Both work on the same platform, and many buildings end up with a mix. A dedicated charger sits in a resident’s own bay, locked to their card. Shared chargers sit in common bays that any resident can use, each session billed to whoever started it. Dedicated suits allocated parking; shared suits buildings where parking is first come, first served.
Does this apply to new buildings as well as retrofits?
Yes, and it is easier. The containment and the capacity are designed in from the start, so bays are made EV-ready at a fraction of the retrofit cost and chargers are added as residents move in. Local building rules increasingly require it anyway.
Can we start with two bays and add more?
Yes, and that is the normal path. The thing worth doing once is the cabling and the capacity — the units themselves can be added a pair at a time as residents ask, and the platform bills on the ports that exist.
Who does a resident call when a charger will not start?
Support is reachable from inside the driver app, so the first call does not come to the building manager. Faults are usually visible to us before a resident reports one at all.
How is the installation paid for?
The building pays its electrical contractor for it and owns the chargers outright as a result. We do not install, and we take no stake in the site; the platform is a per-port subscription on top. Where a block wants the installation cost back over time, a small margin on the per-kWh price is the usual route, and that money goes to the building rather than to us.
Start with the car park and the intake
How many bays, how many residents have asked, and what the building's incoming supply is. That is enough to say whether this is a phase-one project or a bigger one.
