Tender and sealed bid auctions use confidential or deadline-based submission processes rather than open visible bidding. Instead of watching bids rise in real time, participants submit offers under defined rules and wait for the result to be reviewed and confirmed. This page explains how tender and sealed bid formats work, how they differ from one another, and how manual review or approval may apply before a winning bidder is confirmed.
A tender auction is a structured sale process in which interested parties submit offers by a defined deadline under stated rules, rather than competing bid-by-bid in a visible live or timed sequence.
In practice, tender is often used in procurement and property contexts. The process is structured, deadline-based, and rule-led. The seller or buyer may evaluate submissions against price alone or against a wider set of criteria, depending on the tender design.
A sealed bid auction is a sale process where each bidder submits a confidential bid, usually as a best-and-final offer, by a fixed deadline and without seeing competing bids.
Rightmove uses the phrase “sealed bids” to describe situations where multiple interested buyers are asked to submit their best and final offer by a set date and time. In many sectors, sealed bid is the submission method; tender is the broader process around it.
Not always. Sealed bid usually describes how the offer is submitted. Tender often describes the wider process, which may include eligibility rules, documentation, evaluation criteria, and post-deadline review.
The two terms are closely related and are often blurred in ordinary speech, especially in property sales. Your page should separate them cleanly so users understand when they are talking about the submission format and when they are talking about the full sale process.
A manual close means the bidding or submission deadline has passed, but the result is still pending until an auctioneer or authorised operator reviews the offers and manually approves the winning bid.
This matters because these formats often require more than a simple “highest bid wins” rule. The decision may take into account bid conditions, finance status, proof of funds, compliance checks, seller instructions, or other configured platform criteria before the result is confirmed.
They are useful when the seller or buyer wants confidentiality, a clear deadline, and controlled comparison of offers instead of open visible bidding.
This can suit property disposals, regulated processes, strategic sales, specialist procurement, or situations where the parties do not want a public bid ladder shaping behaviour in real time.
