At least once every five years, an Electrical Installation Condition Report must be generated in the majority of normal office contexts. However, frequent routine checks should be undertaken at least annually.

Regarding the frequency of plumbing checks, every two years is recommended. A yearly inspection may not be essential because plumbing systems degrade more slowly than mechanical systems, such as an HVAC system. Therefore, it makes sense to have a professional inspect it every 24 months.
