    Public Sector Net Zero Delivery

    Decarbonising public sector estates is a national priority, and a complex challenge. From legacy infrastructure and funding constraints to stakeholder engagement and long-term planning, public bodies face unique barriers on the path to net zero.
     

    Arthian is a trusted partner to over 100 public sector organisations, delivering tailored decarbonisation solutions that are practical, strategic, and aligned with funding requirements. We continue to support a range of organisations as technical advisors on various funding schemes, we bring deep expertise within the public sector with energy strategy, heat decarbonisation, compliance, and project delivery.
     

    Whether you’re applying for funding, developing a heat decarbonisation plan, or implementing retrofit works, our consultancy-led approach ensures your projects are robust, evidence-based, and future-ready.
     

    We support clients through every stage of their projects, offering support from RIBA Stages 1 – 7. We can assist with:


       

    • Stage 0: Strategic Definition: deciding why you need a project – business case, options, and big-picture goals
    • Stage 1: Preparation & Brief: figuring out what you want = setting budgets, needs, site info and initial ideas
    • Stage 2: Concept Design: first sketches and outline ideas – exploring different design options
    • Stage 3: Spatial Coordination: developing the chosen design – including type, spatial layouts, utilities needed, and planning permissions
    • Stage 4: Technical Design: detailed drawings and specifications – including construction and tendering packs for contractors to price
    • Stage 5: Manufacturing & Construction: the actual building work happening on site and project delivery alongside project management
    • Stage 6: Handover: project completion, commission, checks, handed over. Training and maintenance manuals provided.
    • Stage 7: In Use: the building is occupied/in use. Evaluation, adjustments if needed, and lessons for the future.

    Our Decarbonisation Services

    We offer a comprehensive suite of services to support public sector organisations at every stage of their decarbonisation journey:

    Energy Efficiency Surveys
    Heat Decarbonisation Plans
    Detailed Design and Tender Specification
    Project Management Support
    PAS 2038 Retrofit
    Public Sector Decarbonisation Support
    Energy Efficiency Surveys

    Energy Efficiency Surveys

    Understanding how energy is used across your estate is the first step toward reducing it. Our energy efficiency surveys provide detailed insights into building performance, identifying opportunities for low-cost improvements and strategic upgrades.
     
    We assess:

       

    • Building fabric and insulation
    • HVAC systems and controls
    • Lighting and electrical systems
    • Occupancy and operational behaviours

     
    Our surveys are designed to support funding applications, compliance reporting, and long-term energy planning.

    heat decarbonisation plan

    Heat Decarbonisation Plans

    Heating is often the largest source of carbon emissions in public buildings. Our Heat Decarbonisation Plans (HDPs) provide a structured roadmap to transition away from fossil fuels, and align with funding criteria and the latest government guidance.

    We deliver:

    • Site-level heat demand analysis
    • Low Carbon heating options appraisals
    • Technology focused feasibility studies (e.g. heat pumps, district heating)
    • Phased implementation plans
    • Cost modelling and carbon impact forecasting

    HDPs are essential for securing funding and guiding strategic investment in low-carbon heating.

    Detailed Design and Tender Specification

    Once your strategy is in place, we support your journey from concept to delivery. Our team provides detailed design and tender documentation to ensure retrofit and decarbonisation projects are technically sound, compliant, and ready for procurement.
     
    We offer:

       

    • Technical drawings and specifications
    • Performance requirements and standards
    • Tender analysis with independent evaluation
    • Contractor liaison and clarification support

     
    This service ensures your projects are delivered to specification, on time and within budget.

    Project Management Support

    Decarbonisation projects often involve multiple stakeholders, contractors, and funding bodies. Arthian provides project management support to keep everything on track—from mobilisation to handover.
     
    Our support includes:

       

    • Programme planning and milestone tracking
    • Risk and issue management
    • Stakeholder coordination
    • Witness testing and system commissioning oversight
    • Reporting and funding body liaison

     
    We act as an extension of your team, ensuring smooth delivery and clear communication throughout.

    PAS 2038 Retrofit

    PAS 2038 is the British Standard for non-domestic building retrofit. Arthian supports public sector organisations in delivering PAS 2038-compliant retrofit projects, ensuring quality, consistency, and long-term performance.
     
    We provide:

       

    • Retrofit assessments and planning
    • Design and specification aligned with PAS 2038
    • Monitoring and verification of outcomes
    • Integration with wider decarbonisation strategies

     
    PAS 2038 ensures retrofit works are evidence-based, measurable, and aligned with best practice for complex buildings.

    Public Sector Decarbonisation Support

    Beyond individual services, we offer strategic consultancy to help public sector bodies navigate the full decarbonisation landscape. From funding applications and stakeholder engagement to policy alignment and reporting, we provide the insight and support needed to deliver meaningful change.
