Powering a successful relocation: Preparing a specialist EV maintenance facility in Slough

Powering a successful relocation: Preparing a specialist EV maintenance facility in Slough

When an existing client relocated to a larger premises in Slough, Berkshire, they needed a trusted electrical partner to prepare the building for their operational requirements within a tight timeframe. Pattco delivered a complete programme of electrical testing, installations and remedial work to ensure the site was safe, compliant and ready for use. Working flexibly around other contractors and the client’s move-in schedule, our team installed specialist charging infrastructure, upgraded lighting, improved workplace facilities and ensured full emergency lighting compliance. The project was delivered on time, on budget and without disruption to the client’s operations.

The Brief

Our client, a manufacturer of electric and combustion-powered street sweeping vehicles, was relocating to a larger facility to support the maintenance of their growing fleet of electric vehicles used by local authorities.

The new site needed to be adapted to support their specific operational needs. This included enabling the safe charging and maintenance of large electric vehicles, improving the working environment for engineers and ensuring the building met ongoing compliance requirements.

Key requirements included:

  • Installation of high-capacity charging points for electric sweepers
  • Assessment of electrical capacity to support new infrastructure
  • Commercial LED lighting upgrades to improve workshop light quality for engineering work
  • Upgrades to workplace facilities
  • Ensuring emergency lighting compliance
  • Completing work within the client’s relocation timeline

As an existing Pattco customer, the client trusted us to deliver a practical, compliant solution that would allow them to move in and continue operations without delay.

Our Approach

We began with a detailed assessment of the building’s electrical capacity to determine how best to support the client’s charging requirements. From there, we developed a phased delivery plan to prioritise critical infrastructure ahead of the relocation deadline.

By structuring the work in phases, we were able to complete essential installations quickly while coordinating around other trades on site and the client’s operational needs.

Clear communication and practical advice were central to the project. As we progressed, we identified opportunities to further improve efficiency, safety and usability, which the client incorporated into the scope.

Pattco delivered a comprehensive package of electrical upgrades designed to make the building fully fit for purpose.

Specialist charging infrastructure

We installed a new dedicated charging distribution board to support multiple 63-amp and 32-amp charging points for electric sweepers. This included full load assessments, cable calculations and the installation of surge protection to safeguard valuable equipment.

We also installed a commercial workplace EV charging unit with dual 22kW three-phase chargers to support the client’s company vehicles.

Lighting upgrades

To improve visibility and working conditions within the workshop, we replaced existing fittings with high-efficiency high-bay LED lighting. We also upgraded PIR sensors and installed additional emergency lighting to improve safety and compliance.

Workplace improvements

Additional works included the installation of ultra-efficient hand dryers and new socket installations for office displays and meeting rooms, helping to improve day-to-day usability of the building.

Compliance and ongoing support

Following the main installation works, we carried out emergency lighting testing and remedial works to ensure the site met safety requirements. We continue to support the client with ongoing compliance testing across all their sites nationwide, including PAT testing, as well as additional installations as their needs evolve.

Delivering without disruption

A key priority was ensuring the work did not interfere with the client’s relocation or day-to-day operations.

To achieve this, we:

  • Accelerated early phases to meet move-in deadlines
  • Coordinated with other contractors on site
  • Worked around operational activities once the client had moved in
  • Scheduled testing work to minimise disruption
  • Provided flexible resourcing to meet programme demands

This approach allowed the client to transition smoothly into their new facility while we completed the necessary upgrades.

The Outcome

The project was successfully delivered on schedule and within budget, providing the client with a safe, compliant and fully operational facility tailored to their needs.

The upgraded infrastructure now allows the client to maintain and charge their electric vehicles more efficiently, helping them support their customers while maintaining high safety standards.

Our flexible approach and ongoing support have also strengthened a long-term working relationship, with further works already planned at the site.
