Just more than half (53%) of the children who applied to start Year 7 in September 2017 were able to get their preferred choice of school, with 76% offered a place at one of their top three schools.
A total of 86% were offered one of their six preferred schools.
Councillor Sue Fennimore, Hammersmith and Fulham council’s cabinet member for social inclusion, said: “We have some of the country’s most successful and therefore most popular schools.
“This means many are over-subscribed and so higher numbers of people miss out on their top preferences.
“But we always have enough places for everyone who needs one.”
In comparison, Harrow pupils were far better placed with 73% getting into the top school, 91% in their preferred three schools and 97% at one of their six choices.
The figures released by the Pan London Admissions Board revealed across the capital around a third of children missed out on their first choice of secondary school.
Of the 88,601 applications, 68% of 11-year-olds got their first choice school, and 89% secured a place at one of their top three schools.
Rising pupil numbers in London continues to put pressure on the system to expand capacity and recruit more teachers, with a 2% increase in applications this year.
|Borough||% of pupils offered first choice school||% of pupils offered top three school choices||% of pupils offered place at one of six preferred schools|
|Kensington and Chelsea||61||84||90|
|Hammersmith & Fulham||53||76||86|
Peter John, deputy chair of London Councils and executive member with responsibility for education, said: "The number of pupils starting secondary school in London is growing, and with 94% of the capital's schools rated good or outstanding by Ofsted, it is no surprise that parents are keen to send their children to school in London.
"London boroughs are working with their local schools to meet increased demand so that pupils are offered a good quality school place.
"Despite a 2% increase in the number of applications this year, boroughs have offered 94% of children a place at one of their preferred schools, maintaining the same rate as last year.
"As well as expanding existing schools and building new ones to create additional capacity, London also needs to recruit more teachers to meet the rising demand for places while maintaining our high standards.
"It is therefore deeply worrying that the majority of London's school budgets are set to shrink in the next few years as the new national funding formula is implemented and schools face additional costs such as pensions and the introduction of the new apprenticeship levy."
In Hounslow just fewer than two-thirds (63%) of pupils got into their first choice school, with 93% offered a place at one of their six preferred schools.
The borough saw an increase of 7% in the number of secondary applications made on time by its residents this year - with 100% of pupils receiving an offer for applications made by the closing date.
Councillor Tom Bruce, cabinet member for education and children’s services at Hounslow Council, said: "The increased demand for primary places we have seen over the last eight years is now emerging in our secondary schools.
“I am delighted that we have been able to improve on last year’s figures when it comes to offering secondary places.
"We have been able to offer a school place to all Hounslow children.”
