We were approached by Hollywell, a building contractor in St Albans, to deliver EV charging for their growing fleet. Drivers needed to charge at the office during the day and at home overnight, and the company needed a way to track consumption and reimburse staff fairly across both locations. The office complicated things. It sat within a multi-tenant building where the electricity supply was shared with several other businesses. Without a way to isolate fleet charging from the rest of the building's usage, there was no clear path to fair billing. The other tenants in the building needed confidence that Hollywell was paying their share of the communal electricity costs. The transition to electric vehicles could not move forward until these questions were answered.
Hollywell's office sits within a multi-tenant building where the electricity supply serves several businesses. Fleet vehicles were charging during the working day, but there was no way to separate how much energy the chargers consumed from the rest of the building's usage. Every kilowatt hour drawn by an EV came from the same supply as the lights, heating, and equipment used by the other tenants. The other businesses needed to see that Hollywell was paying their fair share of the communal electricity bill. Without granular data, billing disputes were inevitable. The client needed a system that could record every charging session individually and produce reports clear enough to share with the other tenants each month. The figures had to be accurate, verifiable, and presented in a format that left no room for disagreement.
Six employees were charging company vehicles at home on their own domestic electricity supplies. The company was legally required to reimburse them for business mileage charging, but needed to do so based on actual energy used rather than estimates or flat rate allowances. Each home had a different electricity tariff, and usage varied from driver to driver depending on mileage and charging frequency. Manual tracking through meter readings or spreadsheets would have been unreliable and created disputes over payments. The client wanted a system that calculated reimbursements automatically, produced auditable records for payroll processing, and removed the admin burden from both the finance team and the drivers. The reimbursement process had to be fair, transparent, and hands off once set up.
The charging network spanned seven physical locations: one office car park and six employee homes spread across the area. The office used 22kW commercial chargers designed for fast daytime top ups, while the homes had 7kW domestic units sized for overnight charging. Two different charger models, two different environments, and completely different usage patterns. The client did not want to manage multiple support contracts or chase faults across seven sites. If a home charger went offline at an employee's property, they needed someone to diagnose and resolve it without the driver having to coordinate directly with a manufacturer. One point of contact for maintenance, monitoring, and support across the entire network was a firm requirement from the outset. The system also needed to reduce running costs wherever possible, which meant off-peak scheduling had to work reliably at every home location.

Our management platform connects all 12 chargers into a single network and records every charging session. Each session logs the charger used, the energy consumed, the duration, and the time of day. Monthly reports break this data down by charger, by vehicle, and by billing period, giving Hollywell a complete picture of fleet energy usage. For the office, this solves the shared building problem. Hollywell's fleet consumption is separated from the rest of the building's electricity usage and backed by verifiable data. The other tenants can see exactly how much energy the chargers drew each month. There are no estimates, no disputes, and no guesswork about who owes what. The reports transfer directly into the communal service charge calculations, making the billing process straightforward for everyone in the building.
The platform logs every home charging session automatically. Each employee's consumption is calculated based on actual kWh delivered to their vehicle, not on mileage estimates or flat rate payments. Reimbursement figures are generated each month and sent to payroll without any manual data entry. Every session is recorded with a timestamp, energy reading, and cost calculation, creating a full audit trail. Off-peak tariff scheduling is configured on every home charger. Vehicles charge overnight during cheaper rate periods, reducing running costs for both the employee and the company. The scheduling works regardless of which tariff each household is on. Hollywell receives a single monthly summary showing exactly what each driver charged and what they are owed. The entire process runs without intervention from the finance team.
All 12 chargers report back to our monitoring platform in real time, regardless of whether they sit in the office car park or at an employee's home. If a unit goes offline, throws a fault code, or behaves unexpectedly, our team is alerted automatically. Many issues can be diagnosed and resolved remotely without a site visit, reducing downtime for the driver. For the client, this means one phone number for support. Whether the problem is at the office or at someone's house, the same team handles it. We provide ongoing maintenance for all units, covering both the commercial office chargers and the domestic home installations. Regular performance reports show network health, uptime, and total consumption across all seven locations. The client has full visibility without having to log into multiple systems or chase updates from different providers.
Hollywell now has a 12 charger network that covers their entire fleet operation. Six office chargers keep vehicles topped up during the working day. Six home chargers let staff charge overnight on cheaper tariffs and get reimbursed accurately each month. The management platform connects every charger into a single dashboard, giving the client full visibility across all seven locations.
The billing question that had concerned the other building tenants is resolved. Monthly consumption reports show exactly how much energy the fleet chargers used, broken down by unit and by vehicle. Hollywell pays their share of the communal electricity bill backed by clear data. There are no disputes about usage and no arguments about fair allocation. The reports are generated automatically and require no manual input.
Staff reimbursement runs without intervention. The platform calculates what each driver charged at home, generates the figures for payroll, and keeps an auditable record of every session. Off-peak scheduling reduces running costs across the network. Our team maintains and monitors all 12 chargers remotely. The client has a single point of contact for support, whether the issue is at the office or at an employee's property.
