Leasehold

If one elevation has two colours of external panel, can the survey treat them as the same product?

No. Two colours on one elevation are not proof of one product, one specification or one fire performance. A visual note of panels is not an EWS1 form and not a fire test. A survey of one flat does not inspect the block’s external wall system as a cladding specialist.

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?

Surveyors can record what they see: panel, colour, damage, staining, gaps. Colour is only colour. A later replacement bay, a repaint, or a different batch can share a wall with an older system. Assuming they are the same because they sit side by side overstates the inspection. The home survey standard does not turn that look into an external wall assessment. Lenders who ask for an EWS1 are asking for a different form, produced by someone instructed to do that assessment, not by the surveyor who walked one flat.

Building-safety leaseholder protections are a legal subject. GOV.UK’s guidance is the place to start, and your solicitor should match the building to that guidance rather than to a photograph. Ask the surveyor what they actually saw, and ask them not to collapse two finishes into one sentence if they could not tell them apart. There is no RICS rule that a matching window colour makes the panels the same. Do not describe the note as a fire test when you write to the agent.

What should you ask your surveyor?

Did you assume the panels match, or only record the two colours?
Are you issuing an EWS1? You should not be, on a flat survey.
What could you not see behind either colour of panel?

What are the typical next steps?

Ask for the wording to separate what was seen from what was not tested.
Send that wording to the solicitor with any building-safety questions.
Do not tell a lender the survey was an EWS1.

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.

If both colours look undamaged, is that a fire result?

No. Lack of obvious damage is a visual comment. It is not a test of the product.

Does one cracked panel rate the whole elevation?

Only if the report says so. Ask which part was rated, and do not spread one observation across both colours without the words.
