Our Commercial Office Renewable Energy Services
Big Green Electrical delivers end-to-end design, installation, and compliance services engineered to meet the unique structural and operational requirements of modern office developments.

First-class electrical installation
Energy consumption represents one of the largest overheads for modern corporate offices, and relying entirely on the standard electrical grid leaves companies vulnerable to volatile utility prices. As businesses strive to meet strict environmental targets, commercial buildings must shift from passive consumers of carbon-heavy energy to active hubs of self-generated, sustainable electricity. Failing to upgrade your building infrastructure damages your corporate reputation and exposes your operations to rising operational costs. Big Green Electrical designs and installs comprehensive, high-efficiency renewable energy systems tailored specifically for the commercial and office sector. We help landlords, property managers, and business owners integrate commercial solar photovoltaic arrays, battery storage, and workplace electric vehicle chargers into their buildings. By choosing to modernise your office with our microgeneration systems, you secure long-term price stability and demonstrate real carbon-reduction leadership.

Implementing an integrated, self-sustaining renewable energy profile transforms how your commercial building operates, delivering substantial financial and environmental benefits.
Installing commercial solar panels and battery storage allows your office to generate its own power during daylight hours, reducing your reliance on expensive grid electricity. Storing excess solar energy in on-site batteries allows you to power your facility during peak evening rate periods. This reduces your monthly utility expenditure, allowing you to reinvest vital financial resources back into your business operations.
A corporate commitment to sustainability has a highly positive impact on employee morale and occupant satisfaction. Offices equipped with smart, renewable systems and workplace EV charging docks show employees that their company is taking real action on climate change. Providing your staff with carbon-free commuting options enhances your employer brand, helping you attract and retain top-tier professional talent.
Unstable grid lines can cause voltage drops that reset servers and disrupt office productivity. Integrating commercial battery storage systems provides your office with a reliable buffer against grid fluctuations. These systems store clean energy and release it seamlessly during brief grid dips, protecting sensitive local IT systems and ensuring continuous business operations.
With landlords and corporate tenants facing strict net-zero requirements, upgrading your building with solar PV and EV infrastructure is a highly visible way to meet carbon-reduction goals. Because your building consumes clean, self-generated electricity, it lowers the overall carbon footprint of your operations. This provides a clear competitive advantage when bidding for tenders that require proof of green supply lines.
Big Green Electrical delivers end-to-end design, installation, and compliance services engineered to meet the unique structural and operational requirements of modern office developments.

We begin every office project with a detailed review of your building's energy consumption. Our specialists analyse your peak electricity usage, calculate the load demands of your IT networks, and assess the structural capacity of your roof space. We then provide a clear feasibility report outlining your expected energy generation and initial investment payback periods.
Every office building has unique architectural and energy requirements. We design custom, integrated renewable energy setups that combine roof-mounted solar arrays, commercial battery storage, and smart electric vehicle charging hubs. We also integrate intelligent management software that automatically routes power where it is needed most, ensuring your office operations run with maximum efficiency.
Our highly qualified commercial electricians handle the entire physical integration process. We run secure containment pathways, connect the solar inverters directly to your main distribution boards, and set up fast EV chargers. Every step of the installation is executed to the highest standards, ensuring complete compliance with BS 7671 wiring regulations.
To ensure your renewable installations continue to run at peak efficiency, we provide comprehensive preventative maintenance support. Our engineers conduct regular thermal imaging checks on inverters, test battery cell health, and clean solar panel arrays. We also provide system calibrations to ensure your software is optimised to handle seasonal weather shifts.
