Meeting the Net Zero Challenge & Closing the Gap

Rising costs, new regulations, and grid delays slow progress to net zero. Fragmented supply chains and stalled audits leave estates without delivery.

OCS Energy Services is a vertically integrated, FM-embedded partner, providing end-to-end energy management from audits and M&E upgrades to solar PV, storage, low-carbon heating, and HV grid projects.

Proven delivery across energy audits, M&E upgrades, FM integration, and HV grid projects, supporting both estates and infrastructure programmes.
Expertise in solar PV, battery storage, low carbon heat networks, and wider renewable technologies.
Investment in specialist expertise, geographic reach, and delivery capability across estates and infrastructure.

A Full-Lifecycle Energy Partner for Estates and Infrastructure

OCS Energy Services supports two complementary markets, using one five stage framework from opportunity to performance.

  • Energy Management

    (Estates)

    For NHS Trusts, local authorities, universities, schools, commercial estates and FM-linked private portfolios. Focus: retrofit, heat decarbonisation, renewables, BMS, compliance, and lifecycle planning.

  • Energy Transition

    (Infrastructure)

    For developers, landowners, councils, campuses and public-sector infrastructure sponsors. Focus: grid reinforcement, HV (up to 132kV), battery storage, solar, energy centres, and co-located generation assets.

Proven Delivery, Best Outcomes

Understanding the Opportunity

Gain clarity on where energy investment will make the greatest impact. Discover provides an evidence-led view of your estate or infrastructure, helping priorities emerge and decisions stand up to scrutiny.

What Discovery Provides

  • Evidence-based understanding of current systems and constraints
  • Technical findings translated into practical options
  • Early visibility of costs, savings potential and funding pathways
  • Alignment with regulatory, compliance and investment requirements

From Findings to a Buildable, Fundable and Accountable Plan

Turn insight into confidence. Design shapes discovery outputs into a clear, structured programme that stands up to scrutiny and aligns with how you plan, fund and deliver.

What Design Includes

  • Detailed technical designs ready for delivery
  • Investment cases and financial modelling
  • Procurement-ready specifications and documentation
  • Sequencing aligned to capital, lifecycle and funding cycles

Installation by a Single

Self-Delivering Partner

Turn approved plans into operational assets with confidence. Delivery brings each programme to life using national engineering, infrastructure and FM capabilities.

What Delivery Covers

  • Self-delivery across M&E, renewables, BMS and controls
  • Solar PV, BESS, low-carbon heating and HV delivery up to 132kV
  • HV grid infrastructure up to 132kV
  • Safe, compliant mobilisation in live environments

Protecting Performance, Compliance and Lifecycle

Create visibility, control and predictability across critical energy assets. Maintain goes beyond routine upkeep, supporting informed planning, compliance confidence and consistent performance at scale.

What Maintain Includes

  • Planned and reactive maintenance
  • Statutory and regulatory compliance checks
  • Asset lifecycle and renewal planning
  • Performance assurance and reporting

Sustaining Performance

and Value Over Time

Use live insight to continuously improve efficiency, cost and carbon outcomes. Optimise applies operational intelligence to refine performance as conditions, demand and priorities evolve.

What Optimise Delivers

  • Live monitoring through IoT, sensors and BMS
  • Demand analysis and system optimisation
  • Reporting on energy, carbon and cost savings
  • Continuous improvement and FM integration

Proven, Trusted, Accredited

Certified to the highest standards, our teams combine expert training with industry-leading accreditations to deliver safe, consistent, and compliant services. Independent audits and award-winning practices give you confidence that quality, safety, and performance are never compromised. best practices every time.

Service Excellence

Energy Services built on five pillars that matter most: consistent delivery, measurable savings, resilience, better experiences, and proven progress towards net zero.

Connect with our Team

  • Proven, consistent delivery methods across estates and infrastructure ensure full compliance with existing and evolving Net Zero regulations. Continuous improvement through data-led monitoring and optimisation reduces delivery variation, providing predictable carbon and cost outcomes.

  • Rapid adoption of new technologies such as heat, solar, and BESS is achieved without disruption. A single delivery team under one management contract creates efficiencies and savings, while integrated multi-intervention workflows ensure projects are completed right the first time. Optimised use of assets, grants, and funding delivers maximum return on investment.

  • In-house capability allows mobilisation at scale and speed across the UK, reducing energy and compliance risks. Estates are futureproofed against regulation through integrated design, delivery, and optimisation, with no reliance on third parties. Long-term resilience is secured through self-delivered maintenance and optimisation.

  • OCS teams are already embedded in high-risk and complex estates, offering customers a single, joined-up energy services offer. Transparent proof of carbon and energy savings builds trust, while colleagues are positioned as energy transition experts. Relationships are built on delivery, visibility, and demonstrable results.

  • Carbon reduction and measurable savings are delivered consistently across estates and infrastructure. Stakeholders see clear progress towards Net Zero that is visible to boards, regulators, and the public. Optimised system performance drives both savings and decarbonisation, strengthening ESG reputation and delivering long-term sustainability impact.

FAQs – Five Stage Framework

  • It provides a structured route from early assessment through to installation and ongoing performance. It ensures clarity, accountability and repeatable outcomes across both estates and infrastructure.

  • No. Customers can join at any stage, depending on where their project currently sits.

    Examples:

    • If feasibility work is complete → start at Design
    • If systems are installed → start at Optimise

    If ongoing support is required → start at Maintain

  • Across estates and infrastructure:

    • Heat pumps and low-carbon heating
    • Solar PV
    • Battery Energy Storage Systems (BESS)
    • BMS, controls and IoT solutions
    • HVAC, M&E and lifecycle upgrades
    • HV networks up to 132kV
    • Energy centres and co-located generation

  • Discovery and Design produce investment-ready business cases aligned with funding schemes such as PSDS and Salix, as well as internal capital cycles. Outputs include cost modelling, savings projections, and alignment with compliance.

  • Yes. The approach is used for single buildings, campus environments and multi-site energy programmes.

  • Maintenance and optimisation can be delivered as part of a wider FM contract or as a standalone service. The approach ensures that asset performance and building operations are closely aligned.

  • All work is delivered to regulated standards for estates, energy systems and HV environments. Compliance documentation is provided for every project.

  • Through monitoring, data analysis, and reporting that track energy consumption, operational behaviour, carbon reduction, and savings delivered.
