Funded Retrofit Works and Delivery framework

The framework is designed to accommodate the full range of decarbonisation funding available to public sector organisations across the UK, whichever nation you’re in. In England, this includes the Warm Homes: Social Housing Fund, the Public Sector Decarbonisation Scheme, and the Great British Insulation Scheme. Scotland, Wales, and Northern Ireland each have their own equivalent housing and public estate decarbonisation programmes. The Energy Company Obligation (ECO4 and future iterations) applies UK-wide. The framework also supports any other government-backed grant funding for energy efficiency and retrofit works, wherever it’s administered.

PAS 2035 is the overarching specification for the energy retrofit of buildings, and compliance is a condition of most government-funded retrofit programmes. The framework supports PAS compliance in several ways. Every contractor on the framework has been evaluated for their understanding of and capability to work within the PAS 2030/2035 framework, including their approach to the key stages aligned with PAS 2030, materials planning, labour resourcing, subcontracting arrangements, and supply chain management. The framework includes PAS roles (retrofit coordinators, retrofit assessors, retrofit designers) as a named measure category, so you can procure the professional services that PAS 2035 requires alongside the physical installation works. This means you can appoint the coordination and installation through a single procurement route rather than managing separate procurements for each element. Contractors were also evaluated on their mobilisation and delivery strategies specifically in relation to PAS-aligned key stages, ensuring they have the operational capability to deliver PAS-compliant work at the scale and pace that funded programmes require. For organisations new to PAS 2035 or delivering their first large-scale funded programme, Inprova’s team can advise on how to structure the procurement to satisfy PAS requirements from the outset.

Speed depends on the route you choose and the complexity of your requirement. A direct award to the highest-ranked contractor for your region can get you to a signed contract in a matter of days. This is the fastest route and is suited to straightforward requirements where the framework terms and the ranked contractor’s capabilities align with what you need. A mini-competition, where you invite all 19 framework contractors to bid against your specific brief, typically takes a few weeks depending on the complexity of the specification and the time allowed for responses. For funded programmes with tight spending deadlines, both routes are significantly faster than running a standalone procurement from scratch, which could take months. The framework’s compliance infrastructure is already in place, meaning the time your procurement would otherwise spend on supplier qualification, compliance documentation, and establishing the procurement vehicle has already been done. Inprova’s team manages the process end to end, from specification development through to contract award, so the speed advantage comes without additional burden on your procurement team.

The framework and the DPS serve different needs and can be used alongside each other depending on your requirements. This framework has a fixed list of 19 evaluated contractors with regional, measure-based pricing and is specifically designed for funded retrofit delivery. It is well suited for organisations that have secured funding and need to appoint experienced contractors quickly through direct award or mini-competition from an established, quality-assessed supply chain. The Asset Decarbonisation and Retrofit DPS has an open supply chain where new suppliers can join at any point, covers nine broader categories spanning the full retrofit lifecycle, and allows you to set your own pricing and terms for each competition. It is better suited for organisations that want maximum flexibility, need access to emerging suppliers and specialist capability, or have bespoke commercial requirements. In practice, you might use this framework for a funded insulation and heating programme where speed and contractor experience with grant conditions are the priority, and the DPS for a larger, more complex whole-building retrofit programme where a tailored specification and broader supplier access matter more. Inprova’s team can advise on which route best fits each requirement.

The framework covers retrofit and energy efficiency works for any building type managed by a UK contracting authority, regardless of nation or funding route. This includes schools, colleges, and university buildings, where estates teams are balancing renewal investment with climate resilience and energy efficiency priorities. NHS hospital and clinic buildings, where trusts across the UK are investing in decarbonisation to meet their net zero targets. Council offices, leisure centres, libraries, and community buildings, funded through whichever public sector decarbonisation route applies in your nation. Police stations, fire stations, and ambulance facilities, where blue light services are working to improve energy performance across some of the public sector’s oldest and most complex estates. Defence estate buildings under the MOD’s sustainability commitments. And residential buildings managed by housing associations and local authorities, funded through the Warm Homes: Social Housing Fund and its devolved equivalents, alongside ECO.

Quantum, Inprova’s spend and contract management platform, provides the data visibility and contract management capability that funded retrofit programmes demand. For funded programmes specifically, Quantum tracks contract performance, spend, and supplier obligations in a single secure view. You can see what’s been ordered, what’s been delivered, and what’s been invoiced across every contract. Pricing validation compares invoiced amounts against agreed regional, measure-based rates and flags discrepancies before they compound. Contract tracking with automatic alerts ensures key dates, reporting deadlines, and funding milestones aren’t missed. For organisations that need to report spend, progress, and outcomes to funding bodies, Quantum provides the structured, auditable data that those reports require. Social value commitments made by contractors at award are tracked through delivery, creating evidence of community impact alongside financial and operational performance. For multi-site or multi-phase programmes, Quantum gives programme managers a portfolio-level view of progress across all sites while retaining the detail needed for individual contract management. The platform is cloud-based, accessible from any device, and included as part of your Inprova procurement agreement at no additional cost.

Funded retrofit programmes are frequently affected by changes to spending deadlines, extensions to grant conditions, or modifications to eligible measures as government policy evolves. The Warm Homes: Social Housing Fund has been through multiple waves with shifting timescales. ECO conditions change between iterations. PSDS funding rounds have their own deadlines that may not align with your delivery programme. The framework is designed to accommodate this reality. Contract terms are set at the point of call-off, and Inprova’s team supports you with managing contract variations where funding conditions change during delivery. If a spending deadline is extended, the contract can be adjusted to reflect the new timescale. If eligible measures change, the specification can be revised. If additional funding becomes available and you want to expand the programme scope, the framework’s single-lot structure covering all 13 measure types means you can add measures to an existing contract or procure additional works without starting a new procurement process. Inprova’s team monitors the funded retrofit landscape and can alert you to changes in funding conditions that affect your programme. For organisations managing multiple funded programmes with different deadlines and conditions, Quantum provides the visibility to track each programme’s progress, spending, and compliance obligations independently while maintaining a portfolio-level view.

Yes, and this is common for organisations delivering comprehensive decarbonisation programmes. The Funded Retrofit Works and Delivery Framework covers the physical installation measures and PAS roles. But a complete retrofit programme may also require services that sit outside this framework’s scope: specialist consultancy for decarbonisation strategy, monitoring technology for post-installation performance measurement, compliance services for building safety, or construction works for major structural interventions. Inprova’s other procurement routes complement this framework. The Asset Decarbonisation and Retrofit DPS covers nine categories spanning the full retrofit lifecycle, including net zero consultancy, monitoring technology, and training. The Compliance Framework and DPS cover fire safety, electrical, and other statutory compliance that retrofit programmes may affect. The Capital Works DPS covers larger construction and refurbishment works. You can use multiple Inprova procurement routes within the same programme, appointing different contractors for different elements through the most appropriate route for each. Inprova’s team can help you map your programme requirements against the available procurement routes and design a procurement approach that covers everything you need without running standalone tenders for each element. Quantum consolidates all contracts across all procurement routes into a single view, so you can manage the entire programme’s contracts, spend, and supplier performance from one platform regardless of which route each contract was awarded through.

Social value is embedded in the framework from the supplier evaluation stage through to contract delivery. Contractors were evaluated on their commitment to social and environmental responsibility as part of the 70% quality assessment, including their plans for monitoring and measuring social value performance. Call-off contracts include options for social value clauses and related KPIs, meaning the social value commitments a contractor makes at appointment become contractual obligations that are tracked and enforced. For funded retrofit programmes specifically, social value has a natural connection to the work itself. Retrofit delivery creates local employment, supports apprenticeships in trades with skills shortages, generates spend with local subcontractors and material suppliers, and improves the energy efficiency of buildings in communities that often need it most. The Procurement Act 2023 requires contracting authorities to have regard to maximising public benefit, and funded retrofit is one of the categories where the social value potential is greatest. When you procure through this framework, you set the social value requirements in your call-off documentation, tailored to the specific priorities of your organisation and your local area. Quantum tracks social value delivery alongside contract performance and spend, so you can evidence the community impact of your retrofit programme to funding bodies, boards, and stakeholders with structured, auditable data.

Every contractor on the framework was assessed through a comprehensive evaluation including a detailed selection questionnaire covering insurance, accreditation, competency, and experience. The evaluation was quality-led at 70% quality to 30% price because in funded retrofit, the competence and accreditation of the contractor matters more than the lowest price. Specific areas assessed include PAS 2030/2035 compliance capability, including the contractor’s approach to managing key stages aligned with the PAS framework. Insurance coverage appropriate to the scale and nature of funded retrofit work. Health and safety management systems and track record. Financial stability to sustain large-scale programme delivery. Experience of working with multiple funding streams and managing the specific grant conditions, reporting requirements, and compliance obligations each one demands. Capability to serve as principal contractor and manage subcontractor relationships, quality, and performance. Social and environmental responsibility commitments. And mobilisation and delivery strategies including materials planning, labour resourcing, and supply chain management. The 19 contractors appointed to the framework represent the supply chain that met these standards. Because this is a framework rather than a DPS, the supplier list is fixed for the framework term, meaning every contractor you can appoint has been through this full evaluation process. The ranked supply chain provides a clear starting point for direct award and a competitive field for mini-competitions.

Yes. Many funded retrofit programmes are delivered in phases across multiple buildings or sites, and the framework is designed to support this delivery model. You can procure the entire programme through a single call-off contract with phased delivery milestones, or you can run separate call-offs for each phase if that better fits your funding conditions, delivery timeline, or programme management approach. For organisations managing large, dispersed building portfolios, phased delivery is often the most practical approach. You might start with the buildings where the need is most urgent or where the funding conditions are tightest, then extend to additional sites as resources allow. The framework’s single-lot structure covering all 13 measure types means each phase can include whatever combination of measures is needed without requiring a separate procurement for each building or each measure type. Inprova’s team supports phased programme delivery through specification development for each phase, contract management across all active phases, and the performance monitoring and reporting that funding bodies require. Quantum provides the portfolio-level visibility to track progress, spend, and compliance across all phases and all sites simultaneously, while retaining the detail needed for individual site-level management. For organisations where different sites are funded through different streams with different conditions, Quantum tracks each funding stream’s requirements independently.

Yes. PAS roles including retrofit coordinators are one of the 13 named measure categories on the framework. The retrofit coordinator is a critical role in any PAS 2035 compliant retrofit programme. They manage the end-to-end process from initial assessment through design, installation, and post-installation monitoring. They ensure the whole-building approach that PAS 2035 requires is maintained throughout the programme, meaning the measures specified are appropriate for each building, the installation sequence is correct, and the completed work is evaluated against the intended outcomes. PAS 2035 requires that the retrofit coordinator is independent from the installer in most circumstances, which means you may need to procure the coordination role separately from the physical installation works. The framework supports this because you can run a call-off specifically for PAS services, appointing the coordinator and other PAS roles before or alongside the procurement of the installation works. Some contractors on the framework can provide both coordination and installation, which is permitted under PAS 2035 in certain circumstances, particularly for simpler measures where independence requirements are less stringent. Inprova’s team can advise on the most appropriate procurement structure to satisfy PAS 2035 requirements while keeping the process as straightforward as possible, depending on the scale and complexity of your programme and the specific requirements of your funding stream.
