2. Guide Price vs. Reserve Price, 10% Exchange Deposit & 28-Day Completion

In UK auctions, the Guide Price is an indication of the seller's minimum expectation, while the Reserve Price is the legal minimum below which the auctioneer cannot sell (capped at no more than 10% above a single-figure Guide Price under ASA/RICS rules). When the hammer falls, a binding contract is formed immediately: the buyer pays a 10% deposit on the day and completes within 28 working days.

3. Inspecting the Legal Pack Before You Bid

Never bid at a UK or European property auction without reviewing the Legal Pack: check the Special Conditions of Sale for seller legal/search fee reimbursements, verify the Title Plan and Local Authority Searches, and confirm whether the property is sold with vacant possession or subject to an Assured Shorthold Tenancy (AST).

Frequently Asked Questions (FAQ)

1. What is the difference between a Guide Price and a Reserve Price in UK property auctions?

The Guide Price is a published indication of where bidding is expected to start, whereas the Reserve Price is the confidential minimum price the auctioneer is authorized to accept. By regulation, the Guide Price must not be more than 10% below the Reserve Price.

2. How much deposit is required when winning a UK property auction?

In a traditional (unconditional) UK auction, you must pay a 10% exchange deposit immediately when the hammer falls (usually subject to a £3,000–£5,000 minimum), with the remaining 90% due within 28 working days.
