The AffordaBid guide to bidding confidently at online property auctions.


You've found a property you like, completed your registration and received confirmation that you're approved to bid. So, what happens next?


If you're wondering how to bid at a property auction, you're in the right place. At AffordaBid, we believe buying property at auction should be straightforward, transparent and accessible. Whether you're a first-time buyer, an experienced investor or simply exploring a different way to purchase property, our online auctions allow you to bid from your computer, tablet or smartphone.

Ready. Steady. BID!

This step-by-step guide explains everything from placing your first bid and setting a maximum bid to understanding the auction countdown and what happens when bidding closes.


Step 1: Get Everything Ready Before Bidding

Before placing your first bid, it's important to make sure you've done your homework.

Ensure that you:

  • View the property and satisfy yourself about its condition and suitability.

  • Read the Legal Pack and ask your solicitor to review it.

  • Arrange your finances so you know the funds will be available when required.

  • Understand the costs, including any applicable buyer fees, Stamp Duty Land Tax, legal fees and other expenses.

  • Set your maximum budget and decide how much you're prepared to pay.


Remember: A successful bid at a traditional property auction creates a legally binding commitment to purchase. Don't bid unless you're completely satisfied that you're ready to proceed.


Step 2: Log In and Find Your Property

Visit the AffordaBid website and log in to your account.


Find the property you've registered to bid on and open its auction listing.


You'll be able to see the current bidding position, the auction countdown and the available bidding controls.


Make sure your registration has been approved for that particular property before attempting to bid.


If you haven't registered yet, take a look at our AffordaBid Bidding Registration Guide, which explains how to create an account, verify your identity and get approved to bid.


Step 3: Understand Guide Prices and Reserve Prices

Before bidding, it's worth understanding two important auction terms.


What Is a Guide Price?

The Guide Price is an indication of the property's pricing expectations and its relationship to the reserve. It may be shown as a single figure or a price range. It isn't a valuation or a prediction of the final selling price.


What Is a Reserve Price

The Reserve Price is the minimum amount the seller has authorised us to accept at auction. This figure is confidential and may change during the marketing period.

A property can only be sold through the auction when the reserve has been met and the auction concludes in accordance with the terms of sale.


Step 4: How to Bid at a Property Auction Online

Once the auction is open, you're ready to get involved. You'll see the current bid and the minimum amount required to place the next bid.


Bidding increases in predetermined increments, which are displayed on the auction page.

How to Place Your First Property Auction Bid

  1. Use the + and – controls to select your preferred bid amount.

  2. Click Place Bid.

  3. Check the amount carefully.

  4. Confirm your bid when prompted.

Your bid will then be submitted. You'll receive an on-screen indication of whether your bid has been accepted, and you can follow the bidding activity as the auction progresses.


Important: Always double-check the amount before confirming. An accepted bid is a serious financial commitment and cannot simply be withdrawn because you've changed your mind or made a careless typo.


Step 5: Understand Maximum Bids and Proxy Bidding

One of the useful features of online property auctions is the ability to place a maximum bid, sometimes called a proxy bid. This means you don't have to keep returning to your screen every time another buyer places a bid.


How Does a Maximum Bid Work?

You enter the highest amount you're prepared to pay for the property. The bidding system can then bid automatically on your behalf, up to your chosen maximum.


This helps you remain competitive without having to monitor every individual bid.

Your maximum bid amount is kept confidential from other bidders.


What Happens If Your Maximum Bid Is Below the Reserve?

If your maximum bid is below the property's reserve price, the system will place your bid at the maximum amount you've entered.


What Happens If Your Maximum Bid Meets or Exceeds the Reserve?

If your maximum bid meets or exceeds the reserve, the system will initially bid up to the reserve amount.


It will then continue bidding on your behalf if another buyer places a higher bid, up to your chosen maximum.


If another bidder has already entered the same maximum amount, the earlier maximum bid takes priority.


Property Auction Bidding Example

Imagine a property has:

  • A current bid of £90,000

  • A confidential reserve of £100,000


You enter a maximum bid of £105,000.


The system initially places your bid at £100,000 to meet the reserve. If another buyer bids £101,000, the system can automatically increase your bid to £102,000.


It will continue responding to competing bids, subject to the bidding increments, until your £105,000 maximum is reached. You might win the property for less than your maximum, depending on the other bids received.


Our advice: Decide on your maximum before bidding starts and stick to it. It's easy to get carried away when the competition heats up.


Step 6: Follow the Bidding as the Auction Progresses

As the auction progresses, you can monitor the current highest bid and the remaining time. If you're outbid, you'll receive an email notification so you can decide whether to increase your bid.


You can return to the auction page to place another bid, provided the auction is still open and your registration remains valid. Remember, there's no obligation to increase your bid simply because someone else has outbid you.


Your budget should always come first.


Step 7: Understand the Final 60 Seconds of an Online Property Auction

One of the most important things to understand when learning how to bid at a property auction is the bidding extension window.


Unlike some online marketplaces, placing a bid at the very last second doesn't give you an advantage.


How Does the Auction Bidding Extension Work?

  • If a bid is placed during the final 60 seconds, the countdown is extended to 60 seconds.

  • If another bid is placed during that extension, the countdown resets to 60 seconds again.

  • The auction only finishes when a full 60-second period passes without another bid.


This gives everyone a fair opportunity to respond to competing bids.


Should You Wait Until the Last Second to Bid?

We wouldn't recommend it.

Internet delays, connection problems or the time taken to confirm your bid could mean it isn't received before the auction closes.


There's no benefit in leaving your bid until the final few seconds.


Step 8: What Happens When the Property Auction Ends?

When bidding closes, the result depends on whether the reserve price has been met.


If You're the Highest Bidder and the Reserve Has Been Met

Congratulations! At the close of the auction, the sale becomes legally binding in accordance with the auction contract.


For our traditional unconditional auctions, this constitutes an exchange of contracts between buyer and seller. Both parties are then legally committed to completing the transaction.


If You're the Highest Bidder but the Reserve Hasn't Been Met

Being the highest bidder doesn't automatically mean you've purchased the property.

If the reserve hasn't been reached, the property remains unsold at auction.

We may contact the seller and interested parties to discuss whether a sale can be agreed afterwards.


If You've Been Outbid

You haven't purchased the property, and you're under no obligation to proceed.

Any bidder security authorisation will be released in accordance with the applicable terms. Your card provider may take several days to make the funds available again.


Step 9: You've Won the Auction – What Happens Next?

If you're the successful bidder, we'll contact you following the auction to explain the next steps. The bidder security amount will be charged to your registered card in accordance with the auction terms or you can pay via a bank transfer.


The relevant sale documentation will be issued to the parties and their solicitors, and arrangements will be made for the contractual deposit and completion.


For traditional unconditional auctions, completion is commonly required within 28 days, although the actual deadline will be stated in the property's legal documentation.


Your solicitor will guide you through the legal requirements and transfer of funds.

Remember: Winning the auction isn't the end of the process. You must be ready to complete your purchase within the contractual timescale.


The AffordaBid View: How to Bid at a Property Auction With Confidence

We believe property auctions should be straightforward, transparent and accessible.

Competitive bidding can be exciting, but the most successful buyers are those who arrive well prepared.


Understand the property, get your finances organised, read the Legal Pack and know your limit.


Our advice is simple: do your homework before the auction, so you can bid with confidence when it matters.
