Questions
About the retrofit assessment (pas 2035)
When is a PAS 2035 assessment needed?
Funded retrofit, including ECO4, requires a PAS 2035 assessment and a retrofit coordinator for every home. It's also good practice for any whole-house project.
Is the fee credited?
If you go ahead with the work through LINX within 90 days, the survey fee is credited against your installation. If you don't, you still keep the report.
