Why Every Office Should Plan EV Charging Before 2030

The UK government’s 2030 ban on new petrol and diesel car sales isn’t some distant target. It’s six years away. For office landlords, facility managers and business owners, that timeline means workplace EV charging infrastructure isn’t a nice-to-have anymore, it’s a commercial necessity you need to plan for today.

We’ve been installing EV chargers across London and Essex for years now, and the pattern is clear: businesses that wait until the last minute end up paying more, dealing with longer lead times, and scrambling to retrofit buildings that weren’t designed for the electrical load. The ones who plan ahead? They get better infrastructure, lower costs, and a genuine competitive advantage when it comes to attracting tenants and staff.

Here’s what you actually need to know about getting your office ready for the electric transition.

The 2030 Deadline Is Tighter Than It Looks

When people hear “2030 ban”, they assume they’ve got until December 2029 to do something. That’s not how it works in practice.

First, the ban affects new car sales. But the shift is already happening. Fleet managers are replacing company cars now, not in 2029. Staff who buy EVs today expect charging at work. If you’re a landlord with a five-year commercial lease coming up for renewal in 2026 or 2027, your tenants will be asking about EV provision during negotiations. Not having an answer costs you.

Second, the supply chain doesn’t wait for deadlines. Electrical contractors, DNO connection capacity, and equipment manufacturers all face the same wave of demand. We’re already seeing longer lead times for DNO applications in parts of East London and Essex where substation capacity is tight. The trading estates around the A12 corridor, the business parks near Romford, the office conversions in Stratford, everyone’s waking up to this at once.

Third, building regs are tightening. As of 2022, new non-residential buildings with more than ten parking spaces must install one charge point and cable routes for an additional 20% of spaces. Existing buildings aren’t exempt from market pressure, even if they dodge the legal requirement. Your competitors are installing chargers. Your tenants’ competitors are installing chargers. You’re either keeping pace or falling behind.

What Office EV Charging Actually Involves

Installing workplace charging isn’t like fitting a couple of 13-amp sockets in the car park. It’s a proper electrical project that needs planning, and the earlier you start, the more options you have.

A typical 7kW workplace charger draws about 32 amps. That’s manageable for one or two units. But if you’re looking at ten spaces, twenty spaces, or an entire car park, you’re talking about a significant electrical load that your existing supply probably can’t handle.

Most commercial buildings have three-phase supplies, which helps. But you still need to account for diversity (not everyone charges at once), load management systems (to prevent tripping the main breaker), and whether your incoming supply has enough headroom. In older buildings, the Victorian conversions in Walthamstow, the 1960s office blocks in Ilford, the industrial units turned workspace in Hackney Wick, the existing supply might be maxed out already.

That’s where a proper survey comes in. We assess your current electrical capacity, work out what you can install now without a supply upgrade, and map out what you’d need for future expansion. Sometimes you can start with six chargers and add more later. Sometimes you need a DNO application from day one. Either way, knowing the answer early gives you time to budget and plan properly.

The DNO Question

If your building needs more capacity, you’ll be applying to your Distribution Network Operator, UK Power Networks for most of London and Essex. That process can take anywhere from a few weeks to several months, depending on local network capacity and whether reinforcement work is needed.

In our experience, areas with newer infrastructure (the business parks around Brentwood, the redeveloped zones near Canary Wharf) tend to have better headroom. Older residential-turned-commercial areas can be tighter. The DNO application itself is free for connections up to a certain size, but if network reinforcement is required, costs can run into thousands. Better to find out now than when you’re under pressure from a tenant deadline.

Load Management and Smart Charging

You don’t need to overspec your electrical supply if you’re smart about load management. Modern workplace charging systems can balance the available power across multiple charge points, ramping up or down based on demand and grid capacity.

This matters because workplace charging is different from rapid charging. Staff park for hours. A 7kW charger will add roughly 30 miles of range per hour, more than enough for most commutes, even if the car doesn’t get a full charge every single day. That means you can run more chargers on a smaller supply by spreading the load intelligently.

Some systems integrate with building management platforms, letting you prioritise certain bays (directors, pool cars, visitors) or set charging schedules to avoid peak electricity tariffs. If you’re on a time-of-use tariff, you can schedule charging for overnight or off-peak periods, cutting your running costs by up to 40% compared to daytime rates.

The key is choosing a system that’s expandable. You might start with eight chargers today, but in three years you’ll want sixteen. Make sure the infrastructure you install now can scale without ripping everything out and starting again.

The Commercial Case for Acting Early

There’s a hard cost argument and a soft value argument. Both matter.

On the cost side, installing EV infrastructure during a planned refurb or car park resurfacing is far cheaper than doing it as a standalone project. Groundworks, cabling, and electrical upgrades all cost less when they’re part of a bigger job. If you’re already digging up the car park to fix drainage or repaint lines, adding charge point cabling at the same time is a no-brainer.

You also avoid the rush. Right now, we can usually start a workplace charging project within a few weeks of the initial survey. By 2028, when every office landlord in London is trying to get chargers installed before leases come up for renewal, lead times will be longer and prices will be higher. Supply and demand.

On the value side, EV charging is rapidly becoming a standard expectation, not a premium feature. Businesses want to offer it to staff as a benefit. Tenants want it as part of the building spec. If you’re competing for occupiers in a tight market, and most of London and Essex is a tight market, not having EV provision is a disadvantage.

We’ve worked with landlords who’ve used new EV charging as a headline feature in lease renewals, justifying rent increases or securing longer terms. It’s a visible, tangible upgrade that tenants understand and value, especially if they’re trying to attract staff in competitive sectors.

Grant Funding and Tax Considerations

The government’s Workplace Charging Scheme (WCS) offers up to £350 per socket (capped at 40 sockets per site) for eligible businesses and charities. It’s not available for residential use, and it doesn’t cover all costs, but it takes a meaningful chunk off the upfront capital spend.

To qualify, you need to be installing OZEV-approved chargers, which is standard for any reputable installer anyway, and meet certain eligibility criteria around business type and parking arrangements. The application process is straightforward, but it does add a few weeks to the timeline, so it’s another reason to start planning early rather than rushing at the last minute.

There are also capital allowances to consider. EV charging infrastructure qualifies for the Annual Investment Allowance, meaning you can deduct the full cost from your profits before tax in the year you install it. For a business paying corporation tax at 25%, that’s a significant saving. Your accountant will give you the exact numbers, but the point is that the net cost of installation is lower than the headline price suggests.

What Happens If You Wait

Let’s be clear: nothing catastrophic happens if you don’t install EV chargers by 2029. There’s no legal penalty for most existing office buildings. But the commercial consequences are real.

Staff with EVs will charge at home and expense the electricity, or they’ll use public chargers and claim mileage. Either way, it’s a cost to the business and an inconvenience to the employee. In a competitive labour market, that matters. Small frustrations add up.

Tenants shopping for office space will compare buildings on EV provision the same way they compare on fibre connectivity or bike storage. If your building doesn’t have it and the one across the road does, you’re at a disadvantage. Lease renewals become harder. Void periods stretch longer.

And if you do eventually install chargers in a rush, you’ll pay more for the privilege. Contractors charge a premium for urgent work. DNO applications can’t be fast-tracked. Equipment lead times are what they are. The businesses that plan ahead get better prices, better systems, and better outcomes.

Bottom line: The 2030 petrol and diesel ban isn’t a cliff edge, but it’s the visible marker of a transition that’s already underway. Office buildings without EV charging infrastructure will face commercial pressure long before the legal deadline arrives. The time to plan is now, while you’ve got options, budget flexibility, and the ability to integrate charging into broader refurb or upgrade projects. Waiting until 2028 or 2029 means higher costs, longer delays, and a scrambled retrofit that could have been done properly.
