This register identifies, scores and manages the risks and opportunities that could affect A M Water Services Limited’s ability to achieve its objectives, maintain certification and deliver safely. It is the operational output of Clause 6.1 and the working register that feeds every Management Review.
| Strategic, operational and compliance risks across all business activities |
| Opportunities for improvement, innovation or competitive advantage |
| The scoring method and criteria |
| Control measures and the residual, post-control risk |
| The treatment option chosen for each entry |
| Integration with business planning and the Management Review cycle |
Each of four factors is scored 1 to 4 against a stated definition.
| Factor | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| A. Impact on the business | Low | Noticeable | Great | Severe |
| B. Legal requirement at stake | No regulations | Guidance / ACoPs | Standards | Laws / Regulations |
| C. Likelihood of occurrence | < 0.1 % | 10 % | 50 % | > 95 % |
| D. Frequency of exposure | Almost never | Rare | Regular | Always |
Risk Score = A + B + (C × D), giving a range of 3 to 24. The band follows from the score:
| Score | Exposure | Action required | Timeframe |
|---|---|---|---|
| 3–7 | <span class="risk-low">Low</span> | Monitor only — review annually | 12 months + |
| 8–13 | <span class="risk-moderate">Medium</span> | Mitigate through management controls | Within 6 months |
| 14–19 | <span class="risk-high">High</span> | Implement controls to reduce | Within 3 months |
| 20–24 | <span class="risk-very-high">Very High</span> | Cease activity until reduced | Immediate |
| Option | Description |
|---|---|
| Accept | Current controls deemed appropriate. Monitor. Develop contingency plans where practicable. |
| Transfer | Shift responsibility via contract or insurance. Can be whole or shared. |
| Mitigate | Reduce likelihood through management controls. Reduce consequences via contingency planning / BCP / liability cover. |
| Avoid | Do not proceed with the activity or choose an alternative approach. Risk management — not aversion. |
Every entry carries an inherent score, before the controls in place, and a residual score after them. 22 of 26 entries are reduced by the controls, and 2 remain High or Very High after them. Counted from the rows at build time.
An entry whose residual score equals its inherent score is not an error: it means the controls in place hold the position rather than improve it, which is what Accept describes.
Emerging items not yet formally on the register but under active monitoring (in scope for review earlier than Rev 4):
This register is:
| Role | Responsibility |
|---|---|
| Aaron Mason Director | Owns the strategic and operational risks and the decisions that treat them |
| Leanne Mason Director, HR & Admin | Owns the financial, commercial and people risks |
| Sean Ashton HSQE Consultant | Maintains the register, scores the entries and reports the position to the Management Review |
| Jason May Supervisor | Reports operational risks as they arise on site |
Approved by the Directors. Reviewed as a whole annually, and any entry may be re-scored at any time on an incident, a change of scope or a change in the law. The register is a standing input to the Management Review.
| Issue | Date | Approved by | Change |
|---|---|---|---|
| 1 | 01/06/2024 | Aaron Mason, Director | Initial issue — 13 risks. |
| 2 | 01/06/2025 | Aaron Mason, Director | AI, climate change, supply chain added. |

Residual bands corrected to the AMWS scale — Low, Medium, High, Very High — which the scoring key already set; thirteen entries had been carried as Moderate, Watch or Plan. Four opportunities withdrawn as commercial development rather than management-system matters. |
