Homes for Net Zero Phase 3 (HfNZ P3)
Notice Description
DESNZ is seeking to procure a contractor/s to deliver Phase 3 of the Homes for Net Zero research programme (HfNZ P3). 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. It 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. The programme will require delivery through competitively procured work packages (lots); * Lot 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; * Lot 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. * Lot 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. * Lot 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. Contractors 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). Outputs 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. DESNZ 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.
Lot Information
Trial Management and Coordination
Provides programme-wide trial management, participant engagement, data operations and coordination across all work packages to ensure effective delivery, reporting and governance. 19. The 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
Options: WP 1 (trial management and coordination): Shall coordinate cross-WP delivery planning; chair programme meetings; maintain the integrated delivery plan; manage programme RAID and decision logs; coordinate participant communications and scheduling; and lead the Data Management Plan and data-sharing processes. WP 2 (data analysis & research): Shall specify analysis data/metadata requirements; maintain a reproducible analysis plan and QA approach; and provide timely feedback on the analytical impact of delivery or specification changes proposed by other WPs. WP 3 (consumer engagement & social research): Shall coordinate consumer engagement touchpoints with WP 1 contact plans and WP 4 delivery pathways; and ensure participant-facing materials are accurate, accessible and consistent with what can be delivered. WP 4 (heat pump design and installation): Shall coordinate installation/maintenance activities with WP 1 scheduling, WP 2 data requirements and WP 3; and ensure delivery supports research comparability while maintaining safety and quality.
Renewal: Following a future review of the programme and budgets an additional 1 year extension may be proposed to extend the trial. Beyond this point, future funding and government priorities are uncertain, particularly in the rapidly evolving field of climate research
Data Analysis and ResearchDelivers the analytical framework, data integration and technical research needed to turn monitoring, survey and intervention data into robust evidence and publishable findings
