Duty Holder vs Responsible Person: Who Is Accountable for Water Safety?

Two roles sit at the heart of every legionella control programme. Getting them clear avoids gaps.
4 min read · Updated October 2026

The duty holder

The employer, landlord or person in control of the premises. The legal duty to assess and control the risk sits here and cannot be handed to a contractor.

The responsible person

Appointed by the duty holder to manage the control programme day to day. They need enough authority, competence and knowledge to do the job, and suitable training.

Where contractors fit

A specialist like us can carry out risk assessments, monitoring and remedial works, and advise the responsible person. That support helps you meet your duties, but responsibility stays with the duty holder.

Frequently asked questions

Can a managing agent be the responsible person?

Yes, if they are competent and have been appointed with the authority to manage the programme.
