Digital Tooling for Retrofit Case Management

NookCRM (https://nookcrm.com/) is an open-source case management system developed by Outlandish for community energy groups. Eleven organisations currently use it for energy advice and fuel poverty work. 

The private rented sector (PRS) faces major retrofit challenges: 55% of PRS homes are below EPC C and 24% are fuel poor. With tighter Minimum Energy Efficiency Standards due by 2030, pressures on landlords, tenants and delivery stakeholders will intensify. Billions invested through ECO4 and GBIS risk under-delivery, slowed by multi-party consents (landlords, tenants, freeholders), low trust and fragmented communication. Currently no shared digital tool exists to coordinate this complexity, posing a major barrier for community energy groups delivering retrofit schemes. 

This project will enhance Nook to create the first open-source energy advice and PRS-capable retrofit CRM, enabling groups to deliver faster, fairer, more trusted retrofits for households in vulnerable situations. 

In partnership with Repowering London, Retrofit West and BHESCo they will co-design and pilot key innovations for PRS retrofit case management, supplier and installer management, and support for owner-occupied and advice-to-retrofit work. Repowering London will pilot the system in Newham, which has London’s highest PRS concentration, leveraging their council partnership. Functionality will also be available nationwide, maximising reach and impact. 

By working openly - sharing code and learning - this project positions NookCRM to become the trusted platform for community-led retrofit.
