In the UK, it is generally not considered standard practice for employers or HR departments to request bank statements from employees for the purpose of verifying salary details. The primary source of information regarding salary details is typically the employee's payslips, which provide a breakdown of earnings, deductions, and tax information.
Under the Data Protection Act 2018 and the General Data Protection Regulation (GDPR), employers must have a valid lawful basis for processing personal data, including financial information. Requesting bank statements may be seen as excessive or unnecessary, as it can potentially involve the processing of more personal information than required for payroll purposes.

That being said, there might be exceptional circumstances where an employer could request bank statements. For example, if there are issues with the payroll system, discrepancies in payments, or suspected fraudulent activity, an employer may ask for additional documentation to resolve the matter. However, such requests should be handled carefully and should only be made when there is a legitimate and justifiable reason.
It is always recommended to consult with legal professionals or seek advice from appropriate authorities, such as the Information Commissioner's Office (ICO) in the UK, for specific guidance related to your situation.
