I admit that it can be difficult to find a succinct form of words to complete the comment section. Here is one such;

"The installation is of light commercial construction. It comprises twin with earth/single cables contained within the fabric of the building and in trunking, plastic/metal distribution boards and accessories. All circuits have been provided with modern protective devices and have additional protection in the form of 30mA RCDs.

The installation appears neatly erected and is free from any damage, defect, overheating or deterioration that would be of concern."

Or an example from OSG;

Or an example from GN3

The comment at the top is actually from one of my own crew. Maybe a tad better than the latter two but when I did a QA on it before issue, I found the relatively large installation was very untidy in places, singles in trunking, not a T/E to be seen, every single DB was a fuseboard of 1980s vintage, and only one 100mA RCD on a distribution circuit supplying an external 40 foot container! 

In any event, none of the above examples follow the recommendation in Best Practice Guide 4;

"The summary should adequately describe the general condition of the installation in terms of electrical safety, taking into account the specific observations made. It is essential to provide a clear summary of the condition of the installation having considered, for example:

• The adequacy of the earthing and bonding arrangements
• The suitability of the consumer unit and other control equipment
• The type(s) of wiring system, and its/their condition
• The serviceability of equipment, including accessories
• The presence of adequate identification and notices
• The extent of any wear and tear, damage or other deterioration
• Changes in use of the premises that have led to, or might lead to, deficiencies in the installation.

Minimal descriptions such as ‘poor’, and superficial statements such as ‘recommend a rewire’, are considered unacceptable as they do not indicate the true condition of an installation."

 To be honest, I am not sure how I feel about making a summary comment, I almost think we should either determine the installation satisfactory for continued use or not as the case may be!
