A Prompt Remedy Notice (PRN) may be issued where the BSR wants a particular issue identified during its assessment to be addressed.
This may relate to a specific feature of the building where the safety case does not adequately demonstrate that the associated risk is understood and managed.
For example, the regulator may raise questions about:
- balconies and their construction or attachment
- precast structural elements
- façade or cladding support systems
- compartmentation
- structural alterations
- fire protection to structural elements
- particular construction types or materials
The issue is not necessarily that the feature itself is unsafe.
The problem may be that the safety case has not adequately assessed or explained the risk associated with it.
For example, stating:
"The building has precast concrete elements."
is a building fact.
It does not necessarily demonstrate an understanding of structural risk.
The regulator may need to understand what those elements do, how they are supported or connected, what credible failure mechanisms exist, what is known about their current condition and what measures provide assurance that the associated risk is being managed.
A PRN should therefore be approached as a specific risk question, rather than simply as a request for more narrative.

- How should I respond to a Prompt Remedy Notice?
Treat a PRN as a risk question, not a request for more narrative. Identify the feature, the credible failure scenarios, the consequences, the controls and the evidence behind them.
- What should I do if the BSR identifies a building feature that my safety case has not adequately assessed?
Do not just describe the feature. A description tells the regulator what is there; a risk assessment explains why it matters.
- What if I cannot close an information gap before the BSR response deadline?
Be transparent. A safety case does not become stronger by disguising uncertainty. Explain what is unknown, why it matters, what is known, current controls and the planned programme.
