This is a continuation of our multiyear, largescale research and demonstration trial, building on the existing cohort of approximately 1,250 owner-occupied homes. Among other tasks the appointed contractor(s) will be responsible for trial management and coordination, longitudinal monitoring, data collection and processing, and participant engagement – including physical measurements in homes and social research with occupants. \nIt will include research on practical, scalable pathways to decarbonising owner-occupied homes, particularly complex-to-decarbonise and space constrained properties, with a focus on low carbon heating. This includes evaluating the real-world performance, costs, and user experience of heat pumps (including reversible air-to-air systems), alternative electric heating and domestic hot water solutions. Consumer engagement approaches, and measures to improve resilience to a future climate, such as overheating mitigation, are also key elements of HfNZ P3. \nThe programme will require delivery through competitively procured work packages (lots); \n•\tLot 1: Trial management and co-ordination – including programme management of whole trial, collecting data from monitoring devices and ensuring high data quality, managing trial participants, supporting additional technology trials through an innovation test bed;\n•\tLot 2: Data analysis and research – including technical analysis of in-home monitoring data to answer the research questions, and collaboration with Lots 3 and 4 to ensure methods are designed to address those questions.\n•\tLot 3: Consumer engagement and social research – establishing best practice consumer engagement approaches to transition homes to low carbon heating and using these to support the delivery of measures in Lot 4, carrying out social research to support the research objectives in collaboration with Lot 2. \n•\tLot 4: Design and installation of low carbon heating measures in homes – including, air-source heat pumps, reversible air-air heat pumps, alternative approaches to electric domestic hot water in space constrained homes and the specification and installation of monitoring equipment.\nContractors will need to work collaboratively across the work packages as well as with DESNZ and possibly with linked programmes, notably Built Environment Adaptation and Resilience (BEAR) and Heat Pump Ready Programme (info here: https://www.gov.uk/government/publications/heat-pump-ready-programme/information-about-the-heat-pump-ready-programme#latest-opportunity-from-2026).\nOutputs are likely to include regular, publicly accessible research publications; including two annual reports with research findings, an annual trial delivery summary, and publication of datasets (subject to GDPR).

Among other tasks the appointed contractor(s) will be responsible for trial management and coordination, longitudinal monitoring, data collection and processing, and participant engagement – including physical measurements in homes and social research with occupants. \nIt will include research on practical, scalable pathways to decarbonising owner-occupied homes, particularly complex-to-decarbonise and space constrained properties, with a focus on low carbon heating. This includes evaluating the real-world performance, costs, and user experience of heat pumps (including reversible air-to-air systems), alternative electric heating and domestic hot water solutions. Consumer engagement approaches, and measures to improve resilience to a future climate, such as overheating mitigation, are also key elements of HfNZ P3. \nThe programme will require delivery through competitively procured work packages (lots); \n•\tLot 1: Trial management and co-ordination – including programme management of whole trial, collecting data from monitoring devices and ensuring high data quality, managing trial participants, supporting additional technology trials through an innovation test bed;\n•\tLot 2: Data analysis and research – including technical analysis of in-home monitoring data to answer the research questions, and collaboration with Lots 3 and 4 to ensure methods are designed to address those questions.\n•\tLot 3: Consumer engagement and social research – establishing best practice consumer engagement approaches to transition homes to low carbon heating and using these to support the delivery of measures in Lot 4, carrying out social research to support the research objectives in collaboration with Lot 2. \n•\tLot 4: Design and installation of low carbon heating measures in homes – including, air-source heat pumps, reversible air-air heat pumps, alternative approaches to electric domestic hot water in space constrained homes and the specification and installation of monitoring equipment.\nContractors will need to work collaboratively across the work packages as well as with DESNZ and possibly with linked programmes, notably Built Environment Adaptation and Resilience (BEAR) and Heat Pump Ready Programme (info here: https://www.gov.uk/government/publications/heat-pump-ready-programme/information-about-the-heat-pump-ready-programme#latest-opportunity-from-2026).\nOutputs are likely to include regular, publicly accessible research publications; including two annual reports with research findings, an annual trial delivery summary, and publication of datasets (subject to GDPR). The programme will also deliver thematic research briefs and a final report at project completion, with outputs designed to directly inform DESNZ policy development and analysis on clean heat, energy efficiency, and climate resilience.\nDESNZ is holding a supplier event on MS Teams on Wednesday 29th April 2026 from 1400 - 1600, consisting of presentations by DESNZ and interactive feedback sessions.", "items": [ { "id": "1", "additionalClassifications": [ { "scheme": "CPV", "id": "73110000", "description": "Research services" } ], "deliveryAddresses": [ { "region": "UK", "country": "GB", "countryName": "United Kingdom" }, { "region": "UK", "country": "GB", "countryName": "United Kingdom" }, { "region": "UK", "country": "GB", "countryName": "United Kingdom" } ], "relatedLot": "1" }, { "id": "2", "additionalClassifications": [ { "scheme": "CPV", "id": "73110000", "description": "Research services" } ], "deliveryAddresses": [ { "region": "UK", "country": "GB", "countryName": "United Kingdom" }, { "region": "UK", "country": "GB", "countryName": "United Kingdom" } ], "relatedLot": "2" }, { "id": "3", "additionalClassifications": [ { "scheme": "CPV", "id": "73110000", "description": "Research services" } ], "deliveryAddresses": [ { "region": "UK", "country": "GB", "countryName": "United Kingdom" }, { "region": "UK", "country": "GB", "countryName": "United Kingdom" } ], "relatedLot": "3" }, { "id": "4", "additionalClassifications": [ { "scheme": "CPV", "id": "73110000", "description": "Research services" } ], "deliveryAddresses": [ { "region": "UK", "country": "GB", "countryName": "United Kingdom" }, { "region": "UK", "country": "GB", "countryName": "United Kingdom" } ], "relatedLot": "4" } ], "value": { "amountGross": 9192000, "amount": 7660000, "currency": "GBP" }, "mainProcurementCategory": "services", "aboveThreshold": true, "lots": [ { "id": "1", "suitability": { "sme": true, "vcse": true }, "contractPeriod": { "startDate": "2026-10-12T00:00:00+01:00", "endDate": "2029-03-31T23:59:59+01:00", "maxExtentDate": "2030-03-31T23:59:59+01:00" }, "description": "Provides programme-wide trial management, participant engagement, data operations and coordination across all work packages to ensure effective delivery, reporting and governance.\n19.\tThe appointed supplier for Lot 1 will be required to work with the suppliers awarded the other three lots, as well as coordinating input from suppliers delivering two other programmes, whose objectives overlap with, but will be commissioned separately from, HfNZ Phase 3", "status": "active", "title": "Trial Management and Coordination", "value": { "amountGross": 3720000, "amount": 3100000, "currency": "GBP" }, "awardCriteria": { "criteria": [ { "type": "quality", "name": "Meeting the Requirements", "description": "Meeting the requirements detailing what and how these will be achieved", "numbers": [ { "number": 40, "weight": "percentageExact" } ] }, { "type": "quality", "name": "Skills and Capability", "description": "Describe the team and evidence of of experience", "numbers": [ { "number": 15, "weight": "percentageExact" } ] }, { "type": "quality", "name": "Project Management and Risk", "numbers": [ { "number": 15, "weight": "percentageExact" } ] }, { "type": "quality", "name": "Lot Specific - Managing a programme with Mulitplwe contractors", "numbers": [ { "number": 10, "weight": "percentageExact" } ] }, { "type": "cost", "name": "Cost", "numbers": [ { "number": 10, "weight": "percentageExact" } ] }, { "type": "quality", "name": "Social Value", "numbers": [ { "number": 10, "weight": "percentageExact" } ] } ] }, "hasRenewal": true, "renewal": { "description": "Following a future review of the programme and budgets an additional 1 year extension may be proposed to extend the trial.

This includes evaluating the real-world performance, costs, and user experience of heat pumps (including reversible air-to-air systems), alternative electric heating and domestic hot water solutions. Consumer engagement approaches, and measures to improve resilience to a future climate, such as overheating mitigation, are also key elements of HfNZ P3. \nThe programme will require delivery through competitively procured work packages (lots); \n•\tLot 1: Trial management and co-ordination – including programme management of whole trial, collecting data from monitoring devices and ensuring high data quality, managing trial participants, supporting additional technology trials through an innovation test bed;\n•\tLot 2: Data analysis and research – including technical analysis of in-home monitoring data to answer the research questions, and collaboration with Lots 3 and 4 to ensure methods are designed to address those questions.\n•\tLot 3: Consumer engagement and social research – establishing best practice consumer engagement approaches to transition homes to low carbon heating and using these to support the delivery of measures in Lot 4, carrying out social research to support the research objectives in collaboration with Lot 2. \n•\tLot 4: Design and installation of low carbon heating measures in homes – including, air-source heat pumps, reversible air-air heat pumps, alternative approaches to electric domestic hot water in space constrained homes and the specification and installation of monitoring equipment.\nContractors will need to work collaboratively across the work packages as well as with DESNZ and possibly with linked programmes, notably Built Environment Adaptation and Resilience (BEAR) and Heat Pump Ready Programme (info here: https://www.gov.uk/government/publications/heat-pump-ready-programme/information-about-the-heat-pump-ready-programme#latest-opportunity-from-2026).\nOutputs are likely to include regular, publicly accessible research publications; including two annual reports with research findings, an annual trial delivery summary, and publication of datasets (subject to GDPR). The programme will also deliver thematic research briefs and a final report at project completion, with outputs designed to directly inform DESNZ policy development and analysis on clean heat, energy efficiency, and climate resilience.\nDESNZ is holding a supplier event on MS Teams on Wednesday 29th April 2026 from 1400 - 1600, consisting of presentations by DESNZ and interactive feedback sessions." } ], "items": [ { "id": "1", "additionalClassifications": [ { "releaseID": "033899-2026", "releaseDate": "2026-04-14T15:58:30+01:00", "releaseTag": [ "planning" ], "value": [ { "scheme":
