Start with the direct answer.
A Telecoms Security Act checklist for UK operators should cover the duties that apply, the controls and reviews that support those duties, the owners responsible for the work, the supplier and third-party follow-up behind it, and the evidence trail that proves the work is current.
That matters because a checklist that names obligations without showing ownership and evidence is only half useful. The operational question is always the same: who owns this, what supports it, what changed, and what still needs action before the next request for proof lands?
The checklist needs to be evidence-first.
For many teams, the hardest part is not identifying the topic area. It is keeping the underlying records current enough to defend. Access reviews, supplier oversight, security testing, risk management, asset evidence, and approvals can all exist in different places unless the workflow is deliberate.
That is why TSA work often starts to look like spreadsheet theatre. The document exists, but the supporting operating trail is hard to show cleanly.
What to include in a practical checklist.
The exact shape will vary by operator, but the checklist should make the key operating themes visible and assignable rather than abstract.
- Applicable duties and implementation areas
- Named owners for each evidence or control area
- Supplier and third-party review points
- Access control and identity-management review cadence
- Security testing, resilience, and incident-readiness records
- Linked policies, approvals, and management-review outputs
Keep TSA and ISO 27001 joined up.
The cleanest operating model is usually the one where Telecoms Security Act work and ISO 27001 evidence stay connected instead of living in parallel systems. Controls, risks, policies, suppliers, and approvals are easier to explain when they are not duplicated into separate admin tracks.
That does not mean the regimes are identical. It means the evidence workflow is easier to run if it is structured in one place.

If TSA evidence still feels scattered, compare notes.
A lot of TSA difficulty is not the existence of the duty. It is the work needed to keep the evidence live. If you are in that position, I’m happy to compare notes.
