Leasehold

A staircasing quote is clipped to the shared-ownership lease. Why has the survey not checked that price, and why is GOV.UK's warning about an extension below 80 years a different sum?

The survey has not checked that staircasing quote, because pricing a further share is not the home survey. A figure clipped to the shared-ownership lease is someone else's paper. GOV.UK warns that extending a shared-ownership lease can be much more expensive below 80 years. That warning is about buying extra years on the lease. Staircasing is the price of a larger share. They are different sums. Neither has been calculated here, and the home survey is not a valuation of either bill.

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?

A home survey describes condition. It does not audit a valuation, a housing-association quote, or the arithmetic behind a share. The clipped page may be out of date, limited to a stated share, or silent on fees the provider adds. The surveyor has not tested those assumptions and should not be read as endorsing the number. Keep the quote in the legal pack. Do not treat a paperclip as a check that the price is right.

The lease-extension warning is a different bill from staircasing. Adding years can become much more expensive once the remaining term sits below the point GOV.UK highlights, and that cost is not the price of buying more equity. Your solicitor should keep the two figures apart and ask the provider what each quote includes. The survey has not compared them. Do not tell a lender the clipped staircasing price includes, or replaces, the cost of extending the lease.

What should you ask your surveyor?

  • Has the survey treated the clipped quote as unchecked?
  • Is the lease-extension warning a different sum from staircasing?
  • Which provider papers explain what the staircasing quote includes?

What are the typical next steps?

  1. Keep the staircasing quote as unchecked third-party paper.
  2. Ask the solicitor to separate share price from lease extension.
  3. Do not tell a lender the survey verified either sum.

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 the condition report set the value of the extra share?

No. Condition comments are not a valuation of a shared-ownership share. The survey can describe the flat. It cannot confirm the staircasing price clipped to the lease, and it has not tried. Ask the provider and your solicitor about that figure. Do not lift it out of the pack and call it a survey finding.

Can the two costs fall due at different times?

Yes. Buying a further share and extending the lease are separate transactions, and they need not happen together. GOV.UK's warning is about the extension becoming much more expensive below 80 years. That timing is not a finding that the staircasing quote is due, fair, or inclusive. The survey has not scheduled either payment.
