Lot 15) Innovation & Future Technologies. The Asset Management Lot covers the delivery of a broad range of statutory, compliance driven and condition based property assessment services across domestic and non domestic buildings.

The scope includes, but is not limited to, energy performance assessments, display energy certification, non domestic energy assessments, stock condition surveys and housing condition and safety assessments. The Lot is intended to provide PfH Scotland Members with access to suitably qualified and competent professionals capable of undertaking related property, asset, energy and compliance assessments.

This Lot covers the delivery of specialist surveys, inspections and technical testing services that support the effective planning, design and delivery of decarbonisation and whole building retrofit programmes across domestic, commercial and mixed use properties. The scope includes, but is not limited to, condition and building surveys, structural inspections, fabric and renewables technical surveys, airtightness testing, thermography, damp and mould investigations, and other diagnostic assessments required to inform evidence based retrofit decision making.

This Lot covers the delivery of structured retrofit consultancy services for domestic properties, supporting the compliant planning, coordination and delivery of energy efficiency and decarbonisation improvements. The scope includes, but is not limited to, property assessment, programme coordination, technical design, installation oversight and post-installation evaluation across the full retrofit delivery lifecycle.

Services shall align with relevant statutory requirements, funding and regulatory frameworks, and recognised industry standards and methodologies (e.g. PAS 2035:2023), but are not limited to any single prescribed standard. This Lot provides access to specialist consultancy services to support the assessment, planning and technical development of communal and district heat network projects, together with the evaluation and compliance of existing and proposed systems.

Services are intended to enable informed decision-making by determining whether heat network opportunities are technically feasible, economically viable and environmentally beneficial, and to support progression from early-stage feasibility through to concept design and investment planning. The scope includes, but is not limited to, feasibility studies, option appraisal and early-stage technical development, including the assessment of heat demand, identification of suitable low carbon heat sources, development of concept network configurations and routes, and the evaluation of technical, financial and environmental performance.

The Lot also provides access to services supporting regulatory readiness and ongoing compliance of heat network assets, including structured compliance assessments, performance analysis, and the identification of risks, data gaps and remedial requirements in line with emerging regulatory frameworks and recognised industry standards, such as CIBSE CP1 and the Heat Network Technical Assurance Scheme (HNTAS). Services may be commissioned in relation to new developments, schemes in planning or design, and existing operational networks, and may include a broader range of technical advisory, concept design support, compliance surveys, monitoring strategies and programme-level technical assurance services.

This Lot provides access to specialist consultancy services to support the development, review and implementation of energy and decarbonisation strategies across domestic, non-domestic and mixed property portfolios. Services are intended to support informed decision-making by establishing a robust evidence base, defining baseline energy use and carbon emissions positions, and developing practical, deliverable pathways towards net zero objectives.

The scope includes, but is not limited to, energy and carbon baselining, portfolio analysis and segmentation, option appraisal and the development of net zero strategies, roadmaps and implementation plans. Services may also include programme prioritisation, sequencing and phasing, integration with asset management and investment planning, and the establishment of governance, reporting and performance frameworks.

The Lot also provides access to advisory services relating to funding and policy, including the identification and alignment of programmes with relevant funding opportunities and associated evidence and reporting requirements. Services may be commissioned at any stage, from early strategic advice and baseline assessment through to programme design, investment planning and ongoing advisory support, and may be delivered as standalone commissions or as part of wider decarbonisation programmes.

This Lot is intended to provide access to suitably qualified and experienced Managing Agents capable of delivering end‑to‑end professional services for projects of varying size, value and complexity. Managing Agents appointed under this Framework Lot will be required to act on behalf of the PfH Scotland Member to plan, coordinate, administer and oversee the delivery of works from project inception through to completion and handover.

This includes, but is not limited to, providing strategic, technical, commercial and operational management, together with appropriate programme governance and assurance, to ensure that projects are delivered safely, compliantly, to the required quality standards, within agreed programme timescales and cost parameters, and in a manner that supports effective benefits realisation. The services delivered under this Framework may apply to single projects or multi‑property programmes and may include whole‑house or whole‑building retrofit, fabric improvements, low‑carbon heating and renewable technologies, ventilation measures and associated enabling works.

The Managing Agent shall provide a flexible, scalable service model that can be adapted to reflect differing client priorities, funding arrangements, risk profiles and stakeholder requirements.
