Introduction

Auction property completion takes place after contracts have been exchanged, typically on auction day itself. Understanding what happens between exchange and completion will help ensure the final stage of the transaction proceeds smoothly and without complications.

Auction Commercial Property Completion for Sellers

Following the exchange of contracts at auction, completion will normally take place within 20 to 28 working days, in accordance with the Common Auction Conditions published by the Royal Institution of Chartered Surveyors (RICS), unless alternative terms were agreed in the legal pack.

This relatively short completion timeframe is one of the key advantages of selling commercial property at auction compared with private treaty sales, where transactions can take several months.

Completion usually takes place through solicitors rather than requiring the physical presence of buyer and seller. Funds are transferred electronically between solicitor client accounts, and legal ownership of the property is formally transferred to the purchaser.

1. What happens between exchange and completion

Once contracts have been exchanged, both parties are legally bound to complete the transaction.

During this period:

  • The buyer arranges the balance of purchase funds
  • Solicitors complete final legal checks and documentation
  • Mortgage lenders (if applicable) prepare funds for release
  • Completion statements are issued
  • Insurance responsibilities are confirmed

From the seller’s perspective, your solicitor will prepare for completion by confirming redemption figures for any secured borrowing, calculating fees and ensuring the title can be transferred without delay.

2. Completion day process

On the agreed completion date:

  1. The buyer’s solicitor transfers the remaining purchase funds to your solicitor.
  2. Once funds are received and cleared, completion is confirmed.
  3. Legal ownership transfers to the buyer.
  4. Keys and access arrangements are released.
  5. Your solicitor transfers the net proceeds of sale to you after deducting fees and any outstanding liabilities.

Completion normally occurs between 9:30am and 5:00pm on a working day, although the precise timing depends on when funds are received.

3. Seller responsibilities before completion

Prior to completion you should:

  • Maintain adequate property insurance
  • Ensure vacant possession if required by contract
  • Provide access arrangements as agreed
  • Confirm utility readings if applicable
  • Remove fixtures not included in the sale

Failure to comply with contractual obligations could delay completion or create legal disputes

4. If the buyer fails to complete

Although rare, situations can arise where the buyer fails to complete the purchase.

If this happens, the seller may have several legal remedies, including:

  • Retaining the 10% deposit paid on auction day
  • Charging interest for late completion
  • Reselling the property
  • Claiming damages for financial loss

Your solicitor will advise on the most appropriate course of action depending on the circumstances and the contract terms.

5. Advantages of auction completion for sellers

Selling commercial property at auction offers several completion advantages:

  • Certainty of sale once contracts exchange
  • Fixed completion timetable
  • Reduced risk of gazumping or renegotiation
  • Faster access to sale proceeds
  • Transparent legal process

These factors make auction sales particularly attractive for sellers seeking speed and security.

6. Completion of tenanted commercial property

If the property is sold subject to an occupational lease:

  • Rental income and apportionments are calculated to completion date
  • Tenancy documentation transfers to the buyer
  • Deposits held under tenancy agreements are assigned

Your solicitor will manage these adjustments to ensure financial fairness between both parties.

Summary

Completion represents the final stage of the auction sale process, where ownership transfers and funds are received. Because contracts are exchanged on auction day, completion is usually straightforward and takes place within a defined timeframe. Sellers benefit from certainty and speed, although it remains important to fulfil all contractual obligations to avoid delays.

With proper legal preparation and professional advice, completion following a commercial property auction should be efficient and predictable, allowing you to finalise the sale with confidence.
