Condition ratings
Does a Level 3 of a flat inspect the block’s external wall system?
No. The Level 3 description says the surveyor does not inspect external wall systems of flats and does not carry out specialist tests on them. If they are concerned, they say further investigation is needed. That sentence is not an EWS1 form, and it is not a rating of the cladding system.
Last reviewed 24 October 2026. Written for buyers in England and Wales unless this answer says otherwise. No named surveyor has signed this page. It is general guidance, not a report on your house, and not legal advice.
What is the fuller explanation?
What the surveyor does assess, the description says, is the general condition of outside surfaces, access and communal areas where they can, and the flat itself. They are not opening cladding or checking fire barriers in the cavity of the block. GOV.UK’s building-safety guidance for leaseholders is the legal conversation. The survey is the condition conversation. A stained panel the surveyor could see is still worth reporting. It does not become a completed wall-system investigation.
Ask the surveyor what they could see of the outside from the ground and from the flat, and what they excluded. Ask your solicitor and your lender about EWS1 and leaseholder protections. Do not pay the surveyor to “add an EWS1” onto the same visit. That is not the product described in the Level 3 document.
What should you ask your surveyor?
- What did you see of the outside walls, and what did you exclude as the external wall system?
- Which further investigation do you mean, and who do you expect will do it?
- Which ratings inside the flat are unaffected by that limit?
What are the typical next steps?
- Read the services and outside-wall limitations before you rely on a short summary.
- Ask the lender whether they need an EWS1 for this block.
- Do not describe the Level 3 as a cladding survey in the purchase papers.
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.

Does this limit apply to a house?
The sentence in the description is about flats. A house survey still does not open up solid walls as standard. Ask what was visible.
If the surveyor could see cracked render, is that the external wall system?
It is a condition comment on the surface they could see. It is not the specialist wall-system inspection the description says they do not do.
