Non-standard construction

The mortgage valuation is silent on construction and the Level 3 names a steel frame. Which document do you send the lender about that frame?

Send the Level 3, the document that actually names the steel frame. A mortgage valuation is for the lender. It is not a structural survey, and silence on construction is not a finding that the frame is ordinary. Do not invent a lender policy from that silence. Give them the report that describes the frame, and ask what else they need. The valuation does not replace that description, and it does not become one by being the document the lender ordered.

What is the fuller explanation?

MoneyHelper explains that a mortgage valuation is for the lender. Its job is the lender's security, not a tour of construction for you. It can be short and silent on the very point a Level 3 has spelled out: steel seen here, hidden there, name uncertain or name given. Sending only the valuation leaves the frame out. Sending a retelling in your own words risks changing the surveyor's limit into a slogan. The Level 3 text, with its limits intact, is the document that names the frame. The valuation can still be whatever the lender already holds.

Do not invent a rule that every lender will refuse the steel, or that silence means they have accepted it. Policies differ and are not in the valuation paragraph that never mentioned construction. Ask the lender which report they want attached and whether they need a form answered in a set wording. You can point them to the Level 3 page that names the frame. You should not upgrade a suspicion into a system the Level 3 did not see, and you should not delete the steel to match the valuation's silence. Rating definitions in the Level 3 still describe condition. They are not a lending decision.

What should you ask your surveyor?

  • Which sentences in the Level 3 actually name or limit the steel frame?
  • Does the valuation mention construction at all, or is the silence total?
  • What wording does the lender want, as against what either report already says?

What are the typical next steps?

  1. Send the lender the Level 3 pages that name the frame.
  2. Do not rely on the valuation's silence as a construction finding.
  3. Ask the lender what they need. Do not invent their policy.

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

Is a mortgage valuation a structural survey?

No. It is for the lender. It is not a structural survey, even when a Level 3 exists beside it.

If the valuation is silent, has the lender approved the steel?

Do not assume that. Silence is not a policy. Ask them, and give them the Level 3 that names the frame.
