New builds and warranties
A glass balustrade on a new balcony was not load-tested. What can its condition rating honestly not claim?
It cannot claim a load capacity. The glass was not load-tested, so a condition rating can only describe what was visible: the panels, the handrail and the fixings the surveyor could see without dismantling them. It cannot say the balustrade will resist a given force, and it cannot borrow a test certificate that was not in the papers on the day.

What is the fuller explanation?
New balconies often look finished while the paperwork is still in a site file. A surveyor can see chips, loose bolts, a handrail that stops short, and glass that is cracked or cloudy. Those are condition comments. They are not a load test and not a design check. The rating must stay inside what was done. If the surveyor could not lean on the glass safely, or could not see the fixing into the slab, the report should say so rather than imply the barrier has been proved. Services and structure that were not tested stay untested. A neat line of glass is not evidence of the kilograms it will hold.
Ask the solicitor whether a barrier certificate or a structural note is in the building-control pack for this plot. Ask the surveyor to word the rating so it cannot be read as a test result. If you want a load test, that is a specialist instruction with equipment and a method, not a sentence added to a home survey after the visit. Until that exists, the honest limit is visual: this is what the balustrade looked like, and no one has claimed a capacity for it in this report.
What should you ask your surveyor?
- What could you see of the fixings, and what could you not see?
- Does the rating avoid any figure for load?
- Was a test certificate in the papers you were shown, or not?
What are the typical next steps?
- Read the rating as a visual description only.
- Ask the solicitor for any barrier certificate in the building-control pack.
- Do not add a load figure the survey never measured.
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 glass looks thick, is the capacity adequate?
Thickness you guess by eye is not a test. The rating still cannot claim a load.
Does a missing certificate automatically mean the glass will fail?
No. A missing paper is a missing paper. It is not a load result either way.
