Condition ratings
The stopcock was not located. Is that a condition rating 3 for a leak?
No. A stopcock that was not located is not a condition rating 3 for a leak. Not finding the valve means the surveyor could not point to the internal shut-off. It does not mean water is escaping. There is no leak in that sentence unless the report describes one. Keep a missing valve as an access note, not as an urgent plumbing failure.

What is the fuller explanation?
A stopcock is the internal valve that shuts the incoming water. Not locating it means the surveyor looked, or could not get to the likely places, and did not find it. That is an access limit. Rating 3 is for an element that is serious, urgent, or both, and it is the cue for written quotations before legal commitment. A valve that was not found is not a leak, and it should not be written up as one. If they could not inspect it, NI is the honest mark, and NI is not rating 1 either. There is no repair currently needed to a leak that was not seen, because no leak was described.
Services are visual only and are not safety-tested. Failing to point at a stopcock does not test the rising main and does not prove it is sound. Concealed pipework is not guaranteed sound. The what to do now note advises you. It does not invoice the seller for a leak repair that the report did not find, and it does not require them to cut a floor open because a valve was shy. Ask the agent where the stopcock is, as a practical question for the day you move in. If the report separately describes damp or a drip, rate that drip, and leave the missing valve as the missing valve.
What should you ask your surveyor?
- Is the stopcock NI, rather than rating 3?
- Did you see any leak, separate from not finding the valve?
- Where did you look, and what was boxed in?
What are the typical next steps?
- Do not call a missing stopcock a leak.
- Ask the agent where the valve is, as a practical question.
- Keep any real drip on its own line in the report.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
If the stopcock is buried in a cupboard, is that rating 3?
No. A cupboard that blocked the look is access. NI fits what was not seen. It is not an urgent leak.
Does the pavement valve count as the internal stopcock?
No. The outside valve is a different fitting. Not finding the one indoors is still not a leak.
