Job Summary

The Drinking Water Inspectorate is the independent regulator of drinking water quality in England and Wales. Established by Parliament in 1990, its strategic objective is to protect public health and maintain public confidence by securing safe, sufficient and clean drinking water, now and for future generations.

The Network and Information Systems Regulations (2018) extend the original Drinking Water Supply regulations to include greater emphasis on the security and reliability of information systems which control drinking water production or delivery; and in particular the later day threat of cyber security.

Job Description

The key management responsibility for a Principal Inspector (PI) will be to ensure, via a combination of Inspectors’ and Performance Analysts’ activity and their own, that drinking water companies take appropriate and proportional technical and organisational measures to manage risks posed to both the security of their network and information systems (used in the production or treatment of drinking water) as well as physical security of assets on which their essential service (drinking water) rely. Such a responsibility is pivotal for the relationship developed with each water company – the intent will be to develop a collaborative relationship. The PI will be responsible for escalating any failure or likely failure to enforcement action as appropriate.

The PI will manage a small team of Inspectors and Performance Analysts to ensure all designated (for NIS purposes) water companies across England and Wales comply with the Network and Information Systems Regulations 2018. The regulatory process requires detailed understanding of significant complex operational dynamic systems which control the treatment/production of safe drinking water over multiple operational sites for up to several million consumers at all times.

Management support and leadership will be required from the PI for the small team of Performance Analysts and Inspectors taking a supervisory approach to regulation which includes evaluating technical information about the operation and monitoring of network information systems (Information Technology and Operational Technology) for the production and continuous supply of drinking water. This also includes regular liaison with companies, and informed decisions on improvement plans, based on evidence.

The PI will be responsible for ensuring all water companies in scope are compliant or on a path to compliance, with the regulations through the work of their Inspectors. The technical information, including the receipt of Incident reports, will require audit and assessment against the regulatory requirements, which will also require company site visits to inspect/audit a variety of drinking water production and distribution processes and their management and control. Where necessary, guidance may be required to help a company understand or implement the most appropriate controls to have in place, which may include support for the correct interpretation of regulatory requirements.

The key deliverable will be to ensure that each water company is considering the ‘big picture’ relating to network information systems and physical security, and how their regulatory responsibilities result in a strategy to ensure compliance. The PI will ensure that Inspectors have a clear understanding of the required outcome for water companies to enable Inspectors to enforce effectively. The enforcement process involves an escalatory process of formal requests (notices) for information, to further notices to legally require system improvement, to penalty notices for non-compliance of up to £17m. The PI has complete autonomy for information and improvement notices but will need to justify and escalate any penalty notice and communicate effectively with Senior Management in order to influence the outcome.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
