Officers and SNCOs are required under Queen's Regulations to be a member of a mess and unmarried members usually live, eat, and socialise in them. The JNCOs mess if established is normally used for socialising only, JNCOs usually being accommodated in barrack blocks eating in the cookhouse alongside private soldiers and able rates. Depending on circumstance, such as lack of finance or space, some regiments may have a JNCO "club" instead of a proper mess. Members of their mess are also required to pay a subscription fee for supplies and upkeep. The amount is decided upon by the commanding officer within the limits stipulated by the Regulations.
