Who Is the Responsible Person? (And Why That Title Carries Real Legal Weight)
In facilities management, the title “Responsible Person” sounds simple enough. But don’t let that modest title fool you – this is one of the most important legal roles in your building’s compliance and safety operations.
At Swiftclean, we often hear the same misconception: “We’ve hired a specialist, so they’re now responsible for compliance.”
Unfortunately, that’s not how it works.
You Can Appoint a Specialist, But You Can’t Delegate Responsibility
Whether you’re dealing with Legionella control or kitchen extract cleaning, hiring an external service provider is essential – but it doesn’t remove your legal duty. The law is clear: the legal responsibility remains with the building owner, facilities manager, or premises operator – in other words, the Responsible Person.
This is the person who must ensure that systems are compliant, that preventative measures are in place, and that records are kept up to date. Even if your service provider performs their tasks perfectly, the ultimate responsibility still sits with you.
Legionella Control: Know Your Duties

Legionella bacteria can cause serious illness, including Legionnaires’ disease – a potentially fatal condition. If you’re a landlord, business owner, or facilities manager, you are required by law to:
Identify and assess risks within your water systems
Implement appropriate control measures
Maintain accurate and detailed records
Ensure regular testing and updates to your risk assessments
If you’ve just taken over as the new Responsible Person, it’s your duty to initiate a new or updated Legionella risk assessment, in line with the Health & Safety Executive’s ACoP L8 guidance.
Should an outbreak occur, the Responsible Person is the first to be held legally accountable. However, if your documentation shows that you’ve taken all reasonable steps to prevent the spread of Legionella, you’ll have a strong legal defence.
Key Tip: Always keep before-and-after photos of any cleaning or maintenance work. This visual evidence is invaluable.
