Strategic planning is key to cost-effective fleet electrification
While many fleets focus on hardware costs and lead times, Mer Fleet Services argues a consultancy-led approach is the best way to avoid expensive infrastructure mistakes and ensure long-term success.
In the rapidly evolving landscape of fleet electrification, the initial instinct for many managers is to lead with hardware – comparing charger unit prices and installation lead times. But Natasha Fry, head of sales at Mer Fleet Services, argues that the secret to a sustainable, cost-effective transition lies not in the ‘box on the wall’, but in a rigorous, consultancy-led approach.
Most expensive mistakes in electrification occur long before a single charger is installed. Mer advocates for a consultancy-first model, because an intimate understanding of the underlying infrastructure and the enabling works required is the only way to safeguard a company’s budget.
By conducting professional site surveys, fleet managers can save significant time and capital by ensuring infrastructure is correctly sized for long-term operational goals, rather than simply meeting immediate requirements. This upfront planning ensures improved operational effectiveness, focusing on cost-optimisation and long-term financial benefits that make the transition manageable rather than overwhelming.
One of the most persistent barriers to this transition is the local electricity grid. Many a business fears its local substation lacks the capacity to support a growing commercial fleet, potentially stalling electrification plans for years.
Mer tackles fleet charging challenges in two complementary ways. First, its smart load management technology allows depots to charge far more vehicles than a site’s spare power would traditionally allow. For instance, a depot with capacity for fewer than 10 vehicles could support up to 50 through intelligent, real-time power management. Chargers communicate with each other and the buildings capacity to dynamically adjust power delivery, keeping the site safely within its overall limits. This reduces the need for costly grid upgrades and enables depots to scale their electric fleets without being constrained by traditional infrastructure timelines.
Where additional power capacity is ultimately needed, Mer liaises directly with the local Distribution Network Operator (DNO) to assess feasibility, costs and potential upgrade timelines. By guiding customers through this process, the company provides full transparency on investment and delivery timescales, allowing depots to plan future growth with confidence.

As the financial landscape for EVs continues to evolve, the massive upfront capital expenditure (CAPEX) of depot charging remains a significant deterrent. Mer’s Charging-as-a-Service (CaaS) model is designed specifically to solve this by shifting the financial burden into a predictable monthly operating expense (OPEX). This allows a business to preserve vital cash flow while still accessing premium infrastructure, turning a daunting one-off investment into a transparent line item that aligns with modern budgeting cycles.
Furthermore, Mer ensures these assets do not become obsolete by focusing on high-specification Service Level Agreements (SLAs) designed for operationally critical depots. This maintains the long-term value of a fleet’s electric assets and maximises uptime in an industry where technology moves at a breakneck pace.
This reliability is underpinned by a ‘single source of truth’ for data. The Mer Operator Portal can integrate with existing fleet platforms via open standards such as OCPI and APIs, providing a comprehensive view of charging costs, vehicle readiness and carbon reporting.
Whether a manager needs a ‘single pane of glass’ view for daily operations or needs to feed ESG data into wider corporate systems, the portal provides real-time visibility without adding unnecessary administrative complexity. Backed by Statkraft – Europe’s largest producer of renewable energy with a legacy dating back to 1895 – Mer offers a ‘green’ paper trail that is increasingly vital for stakeholders, offering zero carbon, 100% renewable energy sourced from wind, hydro and solar.
Mer manages large-scale EV charging rollouts across both the private and public sectors, spanning multiple vertical markets. The company's work ranges from supporting global brands such as IKEA and logistics partners including DX Freight and FedEx, through to delivering infrastructure for NHS organisations and the emergency services sector. Its golden rule for any fleet manager remains universal: successful electrification starts with understanding operational data before installing a single piece of infrastructure. By analysing routes, dwell times and energy demand early, even an SME with 20–50 vehicles can size its charging correctly from day one. In an era of data-driven management, Mer UK maintains that the most powerful tool in a fleet manager’s arsenal is a well-informed plan that prevents costly retrofits later.
