Just one-quarter of NAEA members are women, the organisation has revealed.
Taking its own database of members, the NAEA says that nationally, 25.5% of its members are women, but that in London the proportion drops to 18%.
The place with the highest percentage of female estate agents is Cardiff, with 63%.
Figures showing the gender breakdown for ARLA membership have not been released.
But to what extent the figures are a reflection of NAEA membership, or represent the industry at large, is not known in the absence of further data.
However, the president of the NAEA, Wendy Evans-Scott, said: “These figures are disappointing, but unsurprising. Anyone who works in the property industry will testify that the gender balance has only recently started to change.
“Women obviously make up a big part of our customer base and most likely women are the ultimate decision-makers when it comes to purchasing a home.
“There is a lot to be said for having a balanced agency in terms of male and female agents, and many organisations are waking up to this fact. Others still have a long way to go.
“On the plus side, the board representing the NAEA is 38% female – a figure that is well above the Government’s 25% goal for other UK businesses.
“Estate agency is a fantastic career for both men and women, requiring a range of specific skills from communication to negotiation. There is so much variety in this job and you are meeting different people each day.”
Evans-Scott, who runs a branch of Hamptons International in Epsom, Surrey, added: “It makes sense to meet the needs of our customers and have both male and female agents in a branch. This brings a balance of skills and personalities to the table and can offer different empathies within our diversity of clients.”
