End-to-end workflows for your schemes
Retrofit OS provides end-to-end workflows across Warm Homes Social Housing Fund (WH:SHF), Warm Homes Local Grant (WH:LG), PAS 2030 and PAS 2035—so appointments, evidence, compliance checks and submission stay joined up from first visit to handover.
We are also working with our strategic partners on readiness for the new Warm Homes Plan scheme, expected from April 2027.

Designed for how retrofit really works
End-to-end capabilities for PAS 2030 and PAS 2035—from first appointment through install, back office and submission—so teams stay aligned without losing rigour.
Appointments
Schedule and push appointments to assessors, coordinators and installers in the field so everyone sees the same plan and visit windows stay consistent.
Surveys & assessments
Complete structured on-site technical surveys and retrofit assessments with the evidence you need for measures and PAS-aligned documentation.
Forms
Digital forms for certificates, risk assessments and site documentation—consistent formats that reduce missed fields and rework between site and office.
Compliance check
Produce compliance documentation with clear pass/fail visibility and standardised packs, instead of rebuilding evidence sets from scratch for every job.
Install
Book installation work, route jobs to fitting teams and capture install evidence on site through mobile workflows connected to the portal.
Back office
Return mid- and post-install evidence, customer declarations and conformity records to the back office in one place while teams are still on site.
Retrofit coordinator
Coordinators stay connected to installers and assessors: oversee workflows, control documents and progress TrustMark lodgements without juggling disconnected tools.
Submission
Build submission-ready packs with consistent naming and scheme-aligned outputs so portal uploads and handovers take fewer manual steps.
Reporting
Programme and audit-ready reporting—exports and visibility across jobs, evidence completeness and DESNZ-aligned outputs for governance and partners.
