If you're reporting an issue about health and safety where you work, you need to be aware of the protection that employment law gives you as a "whistleblower", especially in relation to unfair dismissal and other potential detriments . You can find out more on whistleblowing from GOV.UK including the importance of the following the correct process.
Disclosing your name
We ask for your name and correct contact details to allow us to follow-up the issue but we will not disclose your name to your employer if you don't want us to. This is one of the questions you will be asked on the online form.
However, depending on the nature and circumstances of the issue it may be possible for your employer to guess that you notified us, particularly if you've already raised the matter with them.
Disclosing information you provide
Occasionally, with good reason, we are asked to keep photographs (or other documents) confidential. We will normally do so, but very exceptionally, when we consider it's necessary to prevent the risk of serious harm, an inspector may need to release the information.
