EV Charger Installation for Apartment Blocks and Shared Car Parks

Flats and shared car parks are where the easy answers about EV charging stop working. A homeowner with a driveway just books a wallbox and gets on with their week. Someone living in a block with a shared parking area has to deal with freeholders, management companies, allocated bays that may or may not actually belong to them, and one electrical supply that was never built with twenty cars charging overnight in mind.

We get asked about this constantly. More from residents who’ve hit a wall with their management company than from the companies themselves, if we’re honest. This guide goes through who actually needs to say yes, what the electrical side involves at this scale, who ends up paying, and how the grants work for this specific situation.

Who Actually Needs to Approve This?

Depends on the setup, and it trips people up more than you’d think. Own your flat outright, including a share of the freehold? You’re often dealing with yourself and your fellow leaseholders through a residents’ association. A separate freeholder or management company running the building? They’re the ones who need to sign off, since the car park and the electrical supply feeding it belong to the building, not to any one flat.

Either way, nothing goes in on communal land without that permission first. No exceptions here. Our guide on EV charger installation for flats and rented properties covers the individual leaseholder side in more depth, and a lot of what applies to one rented flat applies here too, just multiplied across a whole building.

What’s Actually Different About a Shared Car Park?

A driveway install is one charger, one circuit, one electrical supply with capacity to spare in almost every case. A shared car park is a different problem entirely. The supply feeding it has to serve however many residents eventually want a charger, not just the first person who asks.

Get this wrong at the start and the second or third resident who wants one finds out there’s nothing left. A straightforward request turns into a conversation about upgrading the building’s whole electrical supply, and nobody enjoys that conversation. Plan the car park’s electrical setup properly from the first installation, even if it’s just for one resident right now, and you save yourself a lot of pain later.

How Many Chargers Can the Supply Actually Handle?

Comes down to a proper load assessment. Not a guess based on how many bays there are, which is what plenty of residents assume until someone actually explains it. We look at the building’s existing electrical supply, what it’s already carrying, and how much genuine spare capacity exists before confirming how many chargers it can take without upgrading anything.

Load management makes a real difference here. Rather than letting every charger pull maximum current whenever a car happens to be plugged in, a managed system shares available capacity across however many are active at once. It backs off automatically as more cars join instead of tripping the whole supply. That’s what makes ten or twenty chargers on one modest supply actually workable, where running them all flat out, unmanaged, never would be.

Allocated Bays vs Shared Bays

Matters more than people expect going in. An allocated bay, one that belongs to a specific flat, is the simpler case. The charger gets wired to that bay specifically, and the resident’s the only one who ever touches it.

A shared or unallocated car park is trickier. The charger needs to serve whoever happens to park nearest it on a given day, not one fixed resident. That usually means a booking system, or just a first come basis, and it changes how the chargers get metered and billed, because usage can’t get attributed to one flat automatically the way it can with an allocated space.

Who Pays, and Who Gets Billed for the Electricity?

No single answer here, and it depends entirely on how the building wants to run it. Some blocks have residents fund their own charger individually, and that resident covers the electricity through their own metered connection. Others install a shared bank of chargers funded through the service charge, with usage tracked per flat through an app or RFID system so nobody’s quietly subsidising anyone else’s driving.

A straightforward metering setup matters a lot more here than on a single driveway install. Skip it, and disputes over who’s actually paying for what tend to surface within months, not years.

Is There Grant Money for This?

Yes, and it’s worth knowing before assuming residents have to cover the whole cost themselves. Landlords, including freeholders and management companies, can apply for a grant toward the cost of installing EV charging infrastructure that serves residents in flats. Separate funding exists for the wider infrastructure work needed to get a shared car park ready for multiple chargers too, not just the hardware itself. Our EV charger grants page covers current eligibility and how much is actually available, since the figures and criteria do shift from time to time.

Does the Consumer Unit or Supply Need Upgrading?

Often, yes, though it depends heavily on how the building’s original electrical infrastructure was specified. Older blocks in particular were rarely built with this kind of continuous, simultaneous load in mind. Get the supply properly assessed before promising any resident a charger, rather than finding out halfway through a job that the building simply can’t take it as things stand. Our guide on whether you need a new consumer unit for an EV charger explains the kind of checks involved, scaled up considerably for a whole building rather than one home.

Can We Just Install One Charger Now and Add More Later?

Usually, yes. Often the sensible approach too, rather than trying to plan for every future resident on day one. The key is making sure that first installation accounts for future expansion properly, cabling and capacity planned with more chargers in mind, rather than a one off fit that has to be ripped out and redone the moment a second resident asks.

Can Residents Just Install Their Own Charger Without Asking?

No. This is one of the more common misunderstandings we run into. Even a resident who owns their flat outright doesn’t usually own the car park or the electrical supply feeding it too. Our guide on whether you can install an EV charger yourself explains why this needs a qualified electrician for any installation, and that’s before we even get to the permission side of working on communal land and a shared supply.

A Building That Got This Right From the Start

A management company we worked with in Wandsworth had one resident ask for a charger in a forty space underground car park. Instead of fitting the one unit and moving on, we carried out a full load assessment of the building’s supply and designed that first installation with capacity for six more chargers down the line. Cabling was run to accommodate it even though only one charger went in at the time.

Eighteen months later, four more residents wanted chargers. Because the groundwork had already been done, adding each one took a fraction of the time and cost of a standalone installation. The management company ended up with a genuinely scalable setup instead of six separate, disconnected projects bolted on over the years.

A Building Where It Went the Other Way

A different block in Ealing had the opposite experience, with a previous installer, before we got involved. The first charger went in with zero thought given to what would happen if anyone else wanted one. When the second resident applied a year later, there was no spare capacity left at all. The whole car park’s supply needed a significant upgrade just to fit a second unit. What should have been a quick addition turned into a six figure infrastructure project the building hadn’t budgeted for, and nobody was happy about it.

Does This Work the Same Way as a Workplace Car Park?

A lot of the underlying logic carries across, yes. Managing access across multiple chargers, planning for load on a shared supply, deciding who pays for what, all of that shows up in workplace settings too. Our guide on workplace EV charger installation covers that side specifically if you’re comparing the two.

What Does This Actually Cost?

Varies enormously depending on the building’s existing electrical setup and how many chargers are planned for, which is exactly why a proper site assessment matters more here than almost anywhere else. Our EV charger installation cost page gives the broader cost picture that applies across installation types.

Getting It Properly Assessed

Every shared car park project we take on starts with an honest look at the building’s existing supply, how many residents are likely to want a charger eventually, and the car park’s layout. Not a generic per bay quote pulled together without actually checking anything. We run a 7 day turnaround once booked, and we’re already past 15,000 installs across the UK, blocks of flats and shared car parks included. Request a quote and we’ll talk through what your building’s supply can actually handle.

We install across Croydon, Barnet, Richmond upon Thames, Ealing, Watford, Westminster, Wandsworth, Waltham Forest, Tower Hamlets, and Sutton.

A Couple More Things Worth Knowing

Can visitors or guests use the chargers too? Depends entirely on how the building sets things up. Some keep access limited strictly to residents through RFID cards tied to a flat. Others open a bay or two to visitor use, usually billed at a slightly higher rate to cover the admin of tracking a non resident.

What if the building’s freeholder just says no? Worth asking why before giving up. Sometimes it’s a genuine capacity concern that a proper load assessment can actually answer. Other times it’s simply never come up before and nobody’s thought it through yet. Either way, having a clear electrical assessment in hand tends to move that conversation along a lot faster than asking without one.
