Non audit services to listed companies

It's not possible to provide a definite list - everything depends on the circumstance. Essentially anything that would mean the auditor assuming management responsibility is a "no no" (for any client). Administrative services of a routine nature are "ok" (with safeguards as necessary). But bookkeeping/payroll etc for a public interest entity (to use the full term rather than "listed") is not allowed. Valuation services are "ok" if not material (with safeguards as necessary). I'm not going to list them all - essentially you have to consider whether safeguards can reduce any threat to independence to an acceptable level - if yes, it's "ok".
