The “Nadheef” Certificate: your commitment to the highest standards of safety and cleanliness.
The “Nadheef” certificate is a badge of distinction and reassurance that we award to our restaurant clients — conclusive proof of their full commitment to providing a safe, healthy cooking environment that complies with the Civil Defense specifications of the Ministry of Interior, Kingdom of Bahrain.

What does the “Nadheef” certificate cover?
This certificate is granted exclusively after our team completes a deep-cleaning and comprehensive sanitisation process that covers:
-
Restaurant chimneys, exhaust and ventilation systems.
Deep-cleaned and sanitised from the internal hood inside the restaurant all the way up to heights of up to 30 metres.
-
The internal cooking area with all surfaces and equipment.
Cleaned and stripped of residue and deposits so the kitchen is a safe environment free of bacteria and fungi.
A sign your customers will recognise.
Certified restaurants receive the “This restaurant is Nadheef” plaque to display at the entrance. Each plaque carries a unique QR code that opens the restaurant’s verification page on this website, showing the certificate number and validity.
- Restaurant chimneys, exhaust and ventilation systems.
- The internal cooking area with all surfaces and equipment.
- Scan to verify — Certified by Always Clean according to Civil Defense standards, Kingdom of Bahrain.
