Pitshanger Lane faced competition from finalists Raynes Park High Street in Merton and Roman Road in Tower Hamlets.
Ealing Council leader Julian Bell who had met with traders at the start of the competition campaign to pledge the council’s support, said: “Congratulations to all the traders in Pitshanger Lane. This is a huge achievement and they should feel very proud of themselves.
“Pitshanger Lane is a great place to visit with a wonderful range of independent shops and small businesses whether you want to buy a book, meet for a coffee or you are planning to do some DIY at home. I was delighted to support the traders’ efforts in this competition and I am sure that shoppers from across London will come to see for themselves what makes Pitshanger Lane so special.”
The public were asked to vote for their favourite high street and judges also visited Pitshanger Lane last month.
Competition organisers, the Great British High Street said that traders had run a ‘truly impressive campaign to galvanise the local vote.’
They added: “Pitshanger is the deserving winner of the London category. With its great community spirit, social media campaign and a commitment to supporting local retailers, Pitshanger delighted our judges.”
