Case Study
Net Zero Skills for Domestic Energy Retrofitting
An evidence-based study analysing regional workforce needs and skills gaps to support large-scale domestic energy retrofitting and the transition to net zero housing.
PROJECT BACKGROUND
The project sought to understand the non-technical net zero skills gaps for domestic energy retrofitting. It was led by Fife Council and the HCI Skills Gateway at Edinburgh Napier University and was funded by the UKRI’s Net Zero Living: Fast Followers competition.
AIMS & OBJECTIVES



OUR APPROACH
To build a robust evidence base, we partnered with John Gilbert Architects, whose expertise in domestic energy retrofitting complemented Optimat’s experience in Net Zero skills mapping and analysis. The study team analysed address-level data for nearly 670,000 homes across the region, developing local authority datasets projecting the energy efficiency measures and heat decarbonisation installations required for different dwelling types. In collaboration with industry specialists, we produced time-per-measure estimates for various job roles and applied these to each dwelling type. A workforce projection model was then created, enabling the client to test bespoke scenarios by adjusting assumptions on district heat network connections, uptake of energy efficiency measures, and annual deployment rates through to 2045. Alongside the data model, we conducted desk research to assess existing construction workforce supply and demand, providing context for the additional retrofitting skills required. Thirty stakeholder interviews added further qualitative insight.
DELIVERY TEAM
OUTPUTS AND IMPACTS
The key outputs included the study report and the workforce development model. This model produces annual estimates of the Full Time Equivalents required in different job roles and provides important evidence for colleges, universities and private sector skills providers.
This has provided valuable evidence for the regions’ decision makers and particularly those involved in developing workforce skills to support domestic energy retrofitting. The ability to create additional scenarios at a local authority level is also supporting the development of the LHEES delivery plans.
"Working with Optimat offered a collaborative approach to the challenge of quantifying retrofit workforce needs across six diverse local authorities. Optimat were very incisive, quantifying huge volumes of data in a useable way, taking on board any challenges we threw their way. The findings of the project provide a crucial evidence base for supporting future funding and skills development programmes. This will help ensure we have the right people in the right place at the right time to support the journey towards decarbonisation."
