Leasehold

Can the surveyor tell you what it will cost to extend a lease that is under 80 years?

No. GOV.UK’s shared-ownership guidance says that when the remaining lease drops below 80 years it can be much more expensive to extend, and that a short lease can make selling or remortgaging harder. The premium is a valuation and a legal process. A home survey does not calculate marriage value, a premium, or your legal fees. Your solicitor orders the term from the register.

What is the fuller explanation?

Reform of leasehold law has been moving in stages. This page does not guess which bits are in force on a given day. Ask the solicitor to apply the current rules to this lease. Do not subtract a forum’s “lease extension cost” from the price because the survey mentioned the flat.

Condition still matters on a short lease. You might be buying a roof you must repair and a lease you must extend. They are separate cheques. The survey only helps with the first, and only by describing defects, not by pricing them.

What should you ask your surveyor?

  • Are you commenting on condition only?
  • Do you have the lease term? If not, please do not estimate it.
  • Which defects would a short-lease buyer still have to live with?

What are the typical next steps?

  1. Ask the solicitor for the unexpired term and for advice on extension.
  2. Use the survey for the building, whoever owns the lease.
  3. Do not invent a premium from the number 80.

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 80-year point apply in Scotland?

This GOV.UK warning is about the English and Welsh leasehold system it describes. Scotland uses different tenure. Ask a Scottish solicitor.

Is a 999-year lease “under 80” because it started long ago?

No. What matters is the term remaining. A long lease granted recently is not short. Read the register.
