West London is home to the capital's happiest and most miserable residents, according to a new Rightmove survey.
The property website quizzed more than 17,000 people across Great Britain about how happy they are where they live.
While Richmond upon Thames was London's happiest place to live and ranked eighth nationally, it was the only west London borough to make it into the UK's top 10 happiest places.
Westminster was London's 10th happiest place and came 90th in the UK - but Richmond and Westminster were the only two west London boroughs to make the top 10 out of the 31 London boroughs considered in the survey.
But Hillingdon residents, at 27th out of 31 in London, seemed to be significantly less happy about where they live.
Bottom of the pile for the capital at number 31, and ranked 159th nationally, was the west London borough of Brent.
Kensington and Chelsea was not included in the survey because Rightmove said it was not able to collect enough data to make a valid assessment of the borough.
Councillor Muhammed Butt, leader of Brent Council, said: "Brent is a borough full of creativity, energy and potential.
"With food, fashion, music and arts from all over the world, we are one of the best places to live in London.
"96% of our schools are rated as 'good' or 'outstanding' by Ofsted; our GDP grew at 5% in 2016, twice the national average, putting us in the top five fastest growing boroughs; we delivered 30% of affordable housing in the three years to 2015-16 (above the 24% London average); and in a recent attitude survey, 84% of residents said they were satisfied with their area as a place to live.
"It’s disgraceful that Rightmove think it is OK to run down local communities by carrying out skewed surveys to generate publicity.
"That’s not a right move, more like a wrong move."
The national survey showed that southern parts of the UK were most content with seven out of the top 10 happiest places being in the south.
Rightmove’s research manager, Abiola Oni, said: "We’ve looked at the connection between each of the factors and what contributes to how happy people say they are overall, and it’s the people in an area and how someone feels about living there that makes the biggest difference.
"So the strength of community spirit, people feeling like they belong and that they can be themselves are all more important than the services and money that they have, though these do still contribute to overall happiness."
