Do one replaced cladding panel, together with a single bay, count as evidence on the rest of the elevation still original, or only as a note of what was visible?
Only as a note of what was visible. One replaced cladding panel in a single bay shows that this bay has a newer piece. It is not evidence that the rest of the elevation is still original, and it is not evidence that the rest matches the new panel. The other bays were not opened or sampled. A difference, or a match, at one bay stops at that bay. The survey has recorded the replacement it could see. It has not mapped the whole elevation, and it has not produced an EWS1 form for the wall.

What is the fuller explanation?
Cladding is often replaced in small areas after a leak, a dent or a local repair. The new panel can differ in colour, thickness or fixings from its neighbours, or it can be a close match. Neither reading tells you the date or the make-up of the bays you did not open. One bay is one bay. The survey can photograph it and still have no sample of the next bay along. Original, in this note, was not established. It was the thing the single panel could not prove.
Tell the solicitor one bay shows a replacement and the rest of the elevation was not sampled. Ask the managing agent why that panel was changed and whether the papers for the wall, including any EWS1 form, describe the other bays. Do not brief a lender that the elevation is original, or that it has all been renewed. The survey saw one piece. A facade specialist would be needed before anyone treats the whole wall as known.
What should you ask your surveyor?
- Which bay contained the replaced panel, and was that the only one opened?
- Did you compare the other bays, or only see them from the ground?
- Has the rest of the elevation been left unsampled?
What are the typical next steps?
- Limit the replacement note to the single bay you could see.
- Ask the agent why that one panel was changed.
- Do not describe the whole elevation as original or as renewed.
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 new panel matches the colour, is the wall all one system?
No. A colour match at one bay does not show that the rest of the elevation is the same build-up. The survey recorded one replaced panel and did not open the other bays. Matching paint or a similar sheet is not a materials test. The remainder of the wall stays unproved, and no EWS1 form came from this visit.
Does a replacement mean the old panel was dangerous?
Not from this note. A replaced panel shows that a piece was changed. It does not say why, and it does not grade the rest of the elevation. The survey saw one bay. Cause, and any wider problem, were not tested. Ask the managing agent for the paperwork on that repair rather than inventing a reason.
