Welcome to the Middlesex Association of Cricket Officials website.

Here you can find a variety of information about officiating in Middlesex, including officiating resources, and information about upcoming Middlesex ACO courses and events.

If your club is in need of an official, you can also request an umpire or scorer.

If you have never umpired or scored a game of cricket and would like to get involved, or if you are an experienced official looking to progress, please visit our courses section for details of upcoming courses. Most of these courses take place outside of the season during the winter months.

Newly announced courses will be published to our mailing list, which you can sign up to at one of our courses, or you can request access here.
