Professional Indemnity Insurance can respond to certain claims alleging that an Energy Rater’s assessment, calculation, report or professional advice caused financial loss.
Examples can include allegations involving:
- Incorrect energy ratings
- Incorrect software inputs
- Incorrect application of an assessment methodology
- Incorrect assumptions about insulation or glazing
- Building-envelope assessment errors
- Whole of Home modelling errors
- Section J or other energy assessment errors
- Incomplete compliance documentation
- Failure to identify a compliance issue
- Incorrect advice about required design changes
- Delays in reports or assessments
- Additional construction costs arising from an alleged professional error
Depending on the policy, cover can include defence costs, expert expenses and insured liabilities.
Why are records important? #
Useful records can include:
- Plans used for the assessment
- Assessment software files
- Input data
- Assumptions
- Client correspondence
- Design revisions
- Report versions
A claim can require investigation and defence even where the assessor believes the work was correct.
Professional Indemnity Insurance is generally claims-made, so the retroactive date, previous work and continuity of insurance can be important.
