Discuss satisfactory unsatisfactory in the Periodic Inspection Reporting & Certification area at ElectriciansForums.net

You'd just mark it as FI and note why. However you'd also use your engineering judgment based on the condition of everything else as to whether you think it's likely to be an issue or not and issue satisfactory or unsatisfactory on that basis
"FI" automatically makes the Report outcome "Unsatisfactory".

Since when?! On that logic, any LIM is also an unsatisfactory
 
Surely limitation is something you haven't checked, but have no reason to suspect any issues, whereas FI indicates a potential issue which requires further investigation?

As such I fail to follow your logic.
What’s the difference between not conducting an R1R2 on a circuit you can’t find and not conducting one that you can’t deenergise? None whatsoever - both could potentially fail to be safe.

I see where you're coming from, but there is a difference. The unknown circuit could have any number of C1s or C2s on it, you just don't know. The circuit that can't be switched off can be visually inspected, and live tests such as polarity, Zs, R2 etc can indicate the health of the circuit and whether disconnection times are met.

BS7671 page 521 item 9

Since we changed from PIR's and the old coding system to EICRs it has always been that C1, C2 and FI are an automatic unsatisfactory result.
OK - every day’s a school day and having just stuck my head into the books over a coffee for a refresh, I got it wrong-ish.

BPG4 (page 16) says that “Presence of circuits that cannot be readily identified or traced” warrants an FI code. And both BPG and 7671 state that an FI = an unsatisfactory result. So that sadly is that as far as the OP here.

Where I come back to my ‘ish’ is that it’s the job of an inspector to determine whether or not something is safe for continued use. We have all seen test sheets (mostly on here) with circuit after circuit full of LIM - making them largely meaningless but passable. Yet if you can’t find the end of one circuit in an otherwise 100% spanking install, simply because the heating engineer (a theoretically skilled and competent trade) has had to hide it somewhere in an un-obvious location then you have to return a failure and an instruction to the client that they’ll have to dismantle the place brick by brick until you’ve found it??!

With the circuit you cannot de-energise you know what it does and can inspect it and often carry out an R2 and/or Zs test. It is a know quantity and can be assessed.
You make a conscious decision about whether it is acceptable not to test that circuit when agreeing the departure.

An untraced/untraceable circuit is an unknown quantity, you can't inspect it or carry out any tests.

No, no need to dismantle the place.
You use your common sense, if the installation is 100% perfect bar one missing point on a heating system you would probably give it a C3 and advise the customer to contact the heating engineer.

Also you don't return a failure, it is an unsatisfactory result, and you don't give the customer instructions on what to do, you make recommendations.

But in the OP's case it isn't an unidentified circuit, they know that the circuit feeds underfloor heating.

As far as I can see the issue they have is the lack of a local isolator, something that would attract a C3 I think. Presumably they have a thermostat or other control for the underfloor heating where they can carry out tests, otherwise if it's powered 24/7 it's almost certainly burned out and can be isolated at the DB.

The result of those reports will have been based on the engineerging judgement (or lack of) of the inspector.

Agreed limitations won't necessitate an unsatisfactory report.

Sheets filled with limitations won't necessarily mean a satisfactory result, even if no codes are recorded which might generally be expected on an unsatisfactory report.

If certain circuits can not be deenergised, and old reports indicate this has been the situation on successive inspections, then one might pay particular attention to what can be seen of them or perhaps decide it is not acceptable to deem an installation 'satisfactory' when the same chunks of it have been ignored or overlooked for decades.
 
If I had a circuit that I really couldn't identify, even after enquiring about things like sewage or water pumps, then I would disconnect it and notify the occupier, rather than marking it FI in an otherwise satisfactory installation.

You could, but that's getting into the territory of remedial action as opposed to reporting. And you would want to be certain that it's not something critical.
