A visa or work permit is an official document issued by the UK government that explicitly grants an individual the legal right to work in the country. This document is crucial because it provides evidence of the individual's immigration status and confirms that they meet the necessary criteria to engage in employment. In the context of the UK's immigration controls, having a valid visa or work permit is essential for both employers and employees to ensure compliance with legal requirements.

In contrast, the other options do not serve this specific purpose. Utility bills and water bills are personal documents that indicate residency but do not provide any information regarding a person's right to work. A national service record, while it can be a valuable document for various purposes, does not serve as proof of permission to work in the UK. Therefore, the visa or work permit stands out as the only appropriate document to establish an individual's authorization to work in the UK.
