Understanding dual fee commission traps

When an open-market listing stalls, the most common reaction is to fire the underperforming high-street broker and sign a contract with a competing local firm. While this seems like standard business, the hidden fine print inside your original contract can transform a routine switch into a legal trap.

A dual fee commission trap occurs when two distinct estate agencies legally claim they are entitled to full compensation for selling the same property. This situation is not a simple split fee arrangement between companies.

Instead, the seller receives two independent commission invoices from both agencies upon completion. If your home sells for £300,000 at a standard 1.5% fee plus VAT, an unexpected dual fee demand immediately wipes out an additional £5,400 of your hard-earned equity, leaving you paying over £10,800 in total sales commission.

To enforce a double fee demand, estate agents rely on specific contractual terminology surrounding the concept of an introduction. Understanding how these terms shift depending on your contract type is critical before changing providers.

• The effective introduction clause: Under a standard Sole Agency agreement, an agent is only entitled to a fee if they introduce a buyer who goes on to exchange contracts. Legally, they must be the primary cause of the sale. However, if Agent A introduced a buyer who viewed the house but walked away, and Agent B later convinces that same buyer to make a higher offer, both agents can argue they were the effective cause of the transaction.
• The sole selling rights trap: If your original agreement contained the words Sole Selling Rights instead of Sole Agency, the legal landscape becomes highly dangerous. This clause dictates that the original firm is owed a commission if a contract is signed with anyone introduced during their active period—even if the actual sale was entirely negotiated, progressed, and closed by a completely different agency months later.
• The open-ended liability window: Property Ombudsman guidelines suggest that an agent’s right to claim a fee on an introduced buyer should expire 6 months after the contract ends. Despite this guidance, many independent firms still write open-ended or 2-year liability extensions directly into their terms, meaning old financial claims can emerge long after you assume the relationship is over.

Stepping into a dual fee scenario follows a very predictable legal trajectory. Sellers usually do not realize they have made an error until their conveyancing solicitor flags the competing financial demands right before completion.

1 | Agent A introduces an applicant but fails to secure an exchangeThe initial open-market failure and termination.

Your first agent lists the house, registers local buyers, and coordinates a series of viewings. An applicant views the property but declines to make an offer. Frustrated by the lack of progress, you wait out your tie-in clause, serve your written notice, and terminate the contract.

2 | Agent B is appointed and re-evaluates the market strategyInstructing the competing firm under fresh terms.

You sign a fresh sole agency agreement with a new company. Agent B alters the pricing strategy, launches new photography, and matches the property against their database. The original applicant sees the new listing, returns for a second viewing, and submits a successful offer.

3 | Both agencies submit full commission invoices to your solicitorThe discovery of overlapping legal liability.

As the sale nears completion, Agent A discovers that an applicant they originally registered has bought the property. They issue a full commission invoice to your conveyancing solicitor based on their initial introduction. Simultaneously, Agent B demands their full commission for negotiating and closing the deal.

To completely neutralize the risk of a double commission invoice, you must remove the possibility of overlapping introductions. Consider how switching between traditional high-street firms compares directly to exiting the open market entirely:

When you sell your house directly to a corporate cash buyer like National Property Buyers, the entire concept of an agency introduction disappears. Because we act as the sole private buyer using our own capital, there are no portal listings, no public viewings, and no middleman commission structures. You step out of the open-market framework entirely, eliminating any exposure to historical contract liabilities.

Erase the contract risk: Managing overlapping contract terms and tracking historical buyer viewings can be an administrative minefield. If you want to bypass agent transitions, eliminate double fee risks, and secure a clean, guaranteed transition on a certain timeline, a direct sale provides total security.
