Martyn’s Law for restaurants and cafés

A restaurant’s seating plan is one part of the picture. Look at the people reasonably expected together, the spaces in use and how kitchen and front-of-house teams receive instructions.

What the law considers

Food and drink consumed on premises by visiting members of the public is a listed use. The premises test also considers the building, expected simultaneous attendance and exclusions. The ordinary threshold starts at 200 people, including staff, with enhanced tier ordinarily starting at 800. A restaurant within a hotel or shopping centre may need boundary and responsibility review.

Seats and people can be different figures

Connect the dining room and the kitchen

Optional preparation prompts. Agree the local arrangements with the responsible organisation.

  1. Check each use of the space

    Include private dining, a terrace and any separately operated area in the boundary discussion. Record which configuration the published capacity describes.

  2. Confirm expected attendance

    Ask the operator to review bookings and staffing for the busiest relevant service. Keep a range unknown if the evidence cannot support it.

  3. Include every working team

    Agree who briefs reception, kitchen, floor, cleaning and temporary teams on the local procedures relevant to their roles.

  4. Review communication together

    Ask each team how it receives instructions and what the agreed fallback is. Refer to the local plan for the actual method.

The four procedures to review

  1. Evacuation

    Moving people out of the premises or relevant area, away from danger.

  2. Invacuation

    Moving people to a place within the premises where the risk of harm is lower.

  3. Lockdown

    Securing the premises against entry or exit as the circumstances require.

  4. Communication

    Giving people at the premises the information they need.

After commencement, the responsible person must ensure appropriate procedures are in place so far as reasonably practicable. Local circumstances determine which actions are suitable. Relevant people need to understand their roles.

Try a short team discussion

A private dining booking runs alongside normal service. Ask the kitchen and front-of-house leads to explain who gives instructions, how the two groups receive consistent information and who follows up an unanswered question.

Choose a proportionate format and timing. Keep the outcome focused on questions, agreed actions and who will follow them up. This is an optional exercise.

Common questions

Can a published seat count answer the scope question?

It may support the review, but the statutory attendance test concerns everyone reasonably expected together in connection with the use, including staff. Confirm the relevant layout and busy periods.

What if the restaurant is part of a larger venue?

Confirm whether it is separate premises, part of the same premises or nested within qualifying premises. The control and co-ordination questions can differ.
