Business EV Charging and Energy Solutions

Electric vehicles are no longer a niche consideration. With the UK government's zero-emission vehicle mandate and growing employee and fleet demand, businesses of all sizes are being asked to provide or plan for EV charging infrastructure.

What many businesses underestimate is the energy dimension. Installing chargers is only part of the picture. The electricity supply, grid connection capacity, demand management and tariff structure all have a direct bearing on cost and feasibility.

Free Energy Help works with businesses to understand the energy implications of EV charging before commitments are made, helping you avoid costly surprises and procure the right electricity contract to support your charging needs.

Workplace charging is increasingly expected by employees and can form part of a broader staff benefits and sustainability strategy. Whether you are installing a handful of charge points for staff parking or planning a larger multi-bay facility, the energy supply requirements need careful consideration.

The number of chargers, their power rating (typically 7kW, 22kW or 50kW+), and the pattern of use all affect your electricity demand profile. A site that currently has a modest electricity connection may need a capacity upgrade before charging infrastructure can be installed.

We can help you understand the energy supply picture before you engage a charge point installer, so that your electricity contract and grid connection are aligned with your planned infrastructure from the outset.

Businesses operating vehicle fleets face a more complex charging challenge. Fleet vehicles may need to charge overnight at a depot, at multiple sites, or at a combination of on-site and public charging locations. Each scenario carries different energy procurement implications.

Depot charging for a fleet of electric vans or cars can represent a significant and concentrated electricity load. Charging a fleet of 20 vehicles overnight at 7kW each, for example, represents a peak demand of 140kW — a level that many existing business electricity connections cannot support without reinforcement.

Free Energy Help can help fleet operators understand the electricity demand their charging plans will create, identify whether their current supply capacity is adequate, and source electricity contracts that reflect the load profile of fleet charging rather than standard business consumption.

EV charging adds a new and often substantial load to a business electricity supply. Unlike lighting or HVAC, which tend to follow predictable patterns, EV charging demand can be concentrated into specific windows — particularly overnight for fleets or during working hours for staff vehicles.

This concentration of demand matters because electricity tariffs for business customers often include demand-based charges. Exceeding your agreed supply capacity or creating high peak demand can result in additional charges on your bill, sometimes referred to as capacity charges or excess capacity charges.

Smart charging systems and load management technology can help spread demand more evenly, but the underlying electricity contract and supply capacity still need to be appropriate for the total charging load. We help businesses understand how EV charging will affect their demand profile and what that means for their energy costs.

Before installing EV charging infrastructure, it is worth reviewing your current electricity supply capacity. Your supply capacity is defined by your agreed supply capacity (ASC) or authorised supply capacity (ASC), which determines the maximum demand your connection can support without incurring excess charges or requiring a network upgrade.

If your planned EV charging load exceeds your current capacity, you may need to apply to your Distribution Network Operator (DNO) for a capacity increase. This process can take several months and may involve significant costs, so early planning is important.

Free Energy Help can help you review your current supply capacity in the context of your EV charging plans, identify whether a capacity increase is likely to be needed, and ensure your electricity contract reflects the right capacity level — avoiding both unnecessary capacity charges and the risk of supply constraints.

There is no single right approach to business EV charging. The best strategy depends on your vehicle fleet size and type, your site electricity supply, your staff and visitor charging needs, your sustainability objectives, and your budget for infrastructure and ongoing energy costs.

Common approaches include on-site depot charging for fleet vehicles, workplace destination charging for staff, a combination of on-site and public network charging for mixed fleets, and phased rollout strategies that align infrastructure investment with fleet electrification timelines.

We work with businesses to think through the energy dimension of each approach — including the electricity tariff structure, demand management options, and the interaction between EV charging load and other on-site energy use — so that your charging strategy is built on a sound energy foundation.

Many businesses choosing to electrify their fleet or install workplace charging do so partly for sustainability reasons. Sourcing renewable electricity to power your EV charging can strengthen your environmental credentials and support net zero commitments.

Renewable electricity tariffs for business customers are available from a range of UK suppliers. These contracts typically supply electricity backed by Renewable Energy Guarantee of Origin (REGO) certificates, providing evidence that the electricity supplied is matched by generation from renewable sources.

Free Energy Help can help you identify renewable electricity options that are appropriate for your business, including tariffs that specifically support EV charging loads. We provide independent guidance across a broad panel of UK suppliers, so you can compare options without being tied to a single provider.
