What is Your Mailroom’s Role in Your Martyn’s Law Procedures

Your mailroom supports Martyn’s Law by serving as a controlled point where people, parcels and information enter your premises. Staff who handle deliveries every day can follow evacuation and lockdown plans, notice unusual items and maintain records that show your procedures work.

The Terrorism (Protection of Premises) Act 2025, widely known as Martyn’s Law, became law on 3 April 2025, and the Home Office expects it to come into force in Spring 2027. The statutory guidance sets out what responsible persons must do.

Duties depend on capacity. Standard-tier premises hold 200 to 799 people, and enhanced-tier sites hold 800 or more. The Act does not name mailrooms, so the connection between the two comes from how mailroom routines support the procedures the law requires. Offices, universities, venues and hospitals that process large parcel volumes have the most to gain from reviewing them.

Where Mailroom Teams Meet Evacuation, Invacuation and Lockdown Plans

The guidance expects public protection procedures covering evacuation, invacuation, lockdown and communication. Each one has a clear mailroom angle:

• Evacuation - Staff should know the nearest exits from storage areas and loading bays, and who guides couriers and visitors out when an alarm sounds.
• Invacuation - Moving people to a safer place inside the building, known as invacuation, calls for a named safe room that mailroom staff and any delivery personnel on site can reach quickly.
• Lockdown - Deliveries pause, doors are secured and couriers stay out of restricted areas until security leads give the all-clear.
• Communication - Mailroom teams need a reliable way to receive alerts, plus a short script for telling waiting couriers what to do.
• Delivery points - Loading bays and reception handoffs are where unknown visitors meet staff, so access rules there deserve a written procedure.

Steps for Handling a Suspicious Parcel Safely

A short, repeatable sequence helps staff who may handle hundreds of items a day within their wider parcel management routine. Premises should base the warning signs on official police and government guidance, and a typical routine looks like this:

1. Notice - Spot anything unusual, such as an unexpected origin, missing sender details or damaged packaging.
2. Stop - Put the item down and move people away from it.
3. Report - Use the escalation route your premises has set.
4. Follow - Act on instructions from your security lead and the emergency services.
5. Record - Write up what happened afterwards so the team can review the response.

Training, Records and Audit Trails That Back Up Your Plans

Mailroom staff belong in the training programme that covers every employee. Regular drills that include the mailroom, followed by a short review, show where plans need adjusting. Responsible persons should also watch for updates from the Security Industry Authority, which has said it will publish details on how premises notify it once its online system is built. Regulators will expect evidence of effort, and it helps to understand how the SIA will enforce the law before enforcement begins.

Records carry real weight here. A log showing who delivered an item, who signed for it, when it was collected, and where it was stored gives a responsible person evidence that procedures are followed, and it helps investigators reconstruct events. Teams still defining their process can start by reviewing what mailroom management involves and build from there.

A Secure Mailroom Supporting Martyn’s Law Procedures

The mailroom touches access control, staff awareness, communication, and record-keeping, all central themes in the Martyn’s Law guidance. A useful next step is to review how deliveries are received, where couriers wait, and how every parcel is logged, then compare those habits with your premises plan. Dedicated mailroom management software can keep those logs consistent across shifts, and a tool like Parcel Tracker gives your team a clear and searchable record of each parcel from arrival to collection.
