Commission Earned: Top Cities by Fee Income from SSTC Sales

The research shows that, when it comes to potential commission earned, London tops the table with an estimated £14.95 million in commission generated from 1,552 sales likely to complete (85% of 1,826 SSTC listings), based on an average fee of 1.7%.

In Manchester, 576 sales could deliver around £1.87 million in fees to local agents, while Glasgow followed with an estimated £959,000 from 468 completions.

In Edinburgh, agents earned an estimated £763,000 from 263 likely completions, while Bristol rounded out the top five with £726,000 in earnings from 168 transactions.

Other notable totals included £639,000 in Birmingham, £577,000 in Leeds, £454,000 in Liverpool, and £382,000 in Sheffield. Even in cities with lower sales volumes or smaller average fees — such as Bradford, Nottingham, and Leicester - agents still took home between £180,000 and £355,000 in commission income in the last month alone.

Lost Revenue: Missed Referral Earnings from Buyer Leads

Despite these strong results, GetAgent Exchange estimates that agents may still be missing out on additional earnings by not capitalising on buyers who are also sellers - especially when those sellers own property outside the buying agent's patch.

Through GetAgent Exchange's referral model, agents can refer these out-of-area sellers and receive 50% of the referral fee when the sale completes.

London again presents the biggest opportunity, with agents potentially missing out on an extra £708 per deal by not referring these leads. In Brighton, agents could be leaving £517 unclaimed per transaction, while in Bristol it's £450.

Edinburgh and Cardiff agents are missing out on £363 and £341 respectively, while agents in Manchester and Leeds are losing out on £313 and £308 per sale. Even in lower-priced markets like Glasgow (£233), Bradford (£229), and Liverpool (£228), this still represents valuable lost revenue with every missed opportunity.

Colby Short, Co-founder and CEO of GetAgent Exchange, commented:

"Estate agents are rightly focused on securing completions and earning well-deserved commission from those deals, but there's an increasingly important secondary opportunity being overlooked.

When a buyer is also a seller, especially in another part of the country, that's a lead that could be monetised.

With GetAgent Exchange, turning that lead into revenue is simple and effective. And with hundreds of pounds per sale at stake, this is income the industry can't afford to keep ignoring."
