An American franchise company says it is aiming to recruit 3,000 to 5,000 estate agents in the UK who will work in ‘super offices’.

Keller Williams launched in this country 18 months ago.

Visiting London at the weekend, Bill Soteroff, president of KW Worldwide, said that by agent numbers, Keller Williams is now the biggest property franchisor in the world.

He said it is larger than Century 21, Re/Max and Coldwell Banker.

The reason for this, he said, is that Keller Williams has an average of 164 agents in each office – which the firm calls “market centres”.

Century 21, he claimed, averages just over ten agents per outlet, while Re/Max averages just under ten, and Coldwell Baker averages four.

The Keller Williams plan is to have a large number of agents, but a relatively few number of offices. In the States, there are 133,000 agents working out of 710 market centres.

Soteroff said: “The goal is to open each market centre with at least 40 agents committed to it.”

In the UK, where there are now three market centres – two in London and one in Leeds – that goal has clearly not been reached in all offices, with some 90 agents now working from them.

Each market centre is run by a franchisee, who recruits freelance agents who may or may no, pay a desk fee and split their earnings 70:30 with the franchisor.

The agents also pay for training, coaching and IT.

When the market centre gets into profit, each agent gets to share the profitability. Agents make money from sales and also from referrals.

In the States, where Keller Williams began before it launched its crack at worldwide domination three years ago, the average fee earned per agent is 6% – 3% paid by both seller and buyer.

Were the UK’s low fees a concern before Keller Williams decided to enter the market? Apparently not, according to Soteroff, who says that worldwide, Keller Williams is currently growing at the rate of 2,000 agents per month.

American franchise models have not always done well in the UK. However, Soteroff says that the Keller Williams business model is not particularly American, adding: “I view the entry of Keller Williams into the UK as a success.”

Yesterday Keller Williams had 71 available properties listed on Rightmove, ranging from £340,000 to £3.8m, while the firm says that altogether it has over 140 properties for sale plus some rental stock.
