Offices and public buildings.

Powering lower-carbon public estates with reliable, long-term solutions.

Public buildings, council offices, libraries, and civic facilities are under growing pressure to reduce operational costs while meeting sustainability and net-zero targets. Carbon3 helps the public sector decarbonise their buildings using solar photovoltaic (PV), battery storage, and EV charging.

Whether you’re upgrading a single site or planning multi-building decarbonisation across your estate, we provide future-proof installations that improve energy performance and reduce demand on the grid. Decarbonise your estate with fully-funded solar.

Renewable energy solutions for offices and public buildings

Solar PV and Battery Storage for Public Sector Estates.

Solar PV is one of the quickest ways to reduce electricity costs across public buildings. Offices, libraries and community hubs typically operate during daylight hours, making them ideal for high self-consumption while the panels are generating energy.
Pairing solar PV with battery storage helps you maximise these gains by storing surplus energy for evening use, during peak tariffs, or in the event of outages. This provides both long-term resilience and immediate savings.
If your building does not have a suitable roof space, you can utilise your carpark by installing a solar canopy. These shelter your staff and visitors from the elements while generating electricity.

EV Charging for Staff, Fleets and Visitors.

With the public sector leading the transition to low-emission transport, reliable EV charging infrastructure is now essential across offices and public buildings.
We design and install smart EV chargers suitable for your staff, visitors and fleets. Using the Carbon3 App, you can set different charges for each user group. Let your staff charge for free as an incentive, and have the general public pay to charge for a new revenue stream.
Our chargers integrate seamlessly with solar PV, load management systems and on-site battery storage.

Public sector building supported by renewable energy funding

Available Funding for Public Sector Decarbonisation.

Public buildings can access a range of funding mechanisms to support Solar PV, battery storage, EV charging and energy-efficiency upgrades. For EV charging, your organisation could utilise the Workplace Charging Scheme (WCS), and EV Infrastructure Grant for Staff and Fleets.

While the current wave of Great British Energy is already allocated, there may be another wave. Another option if you do not have capital expenditure ready is fully-funded solar.

    Can we install solar without upfront capital?

    Find out how you can install solar with no upfront costs using fully-funded solar.

    How much can a public building save with Solar PV?
    Savings vary by building size and usage patterns, but many offices reduce grid electricity consumption by 25–50% with Solar PV.
    Can installations be completed while the building stays open?
    Yes. We regularly install Solar PV, battery storage and EV chargers with minimal disruption to staff and public access.
    What buildings are best suited for Solar PV?
    Council offices, community centres, libraries, emergency service buildings and schools typically have strong daytime demand, making them ideal. However, most buildings can save with solar PV. We can do a no obligation desktop survey to see how you’re your organisation could save.
    Do I need planning permission?
    Most Solar PV systems fall under permitted development, but we’ll advise on any planning or structural requirements.
