Onam—a ten-day harvest festival rooted in Kerala legend—celebrates the annual return of the legendary King Mahabali. Back home in South India, the festival is defined by lush tropical landscapes, sprawling floral carpets (pookalam), and grand boat races (Vallam Kali). Thousands of miles away, across British cities from London to Birmingham, Leicester, and Glasgow, the UK’s Keralite diaspora proves that distance does not dilute tradition; it deepens it.
While native tropical blossoms yield to marigolds sourced from local South Asian grocers and riverboat races give way to indoor tug-of-war competitions (vadamvali), the core ethos of Onam remains unchanged. It is also a unifying celebration, bringing together Keralites of different faiths—Hindus, Christians, and Muslims alike—to share a multi-course vegetarian Onasadya feast served on fresh banana leaves.
Recreating Childhood and Passing the Baton
For many British Malayalis, celebrating Onam at home is an intimate act of heritage preservation, a blend of nostalgic ritual and intergenerational storytelling.
Rashmi Prabhakar, Head of SaaS Transformation at Temenos, with more than 25 years of experience across banking, energy and fintech, is planning to celebrate Onam this year by welcoming some of her close family and friends to share the warmth, joy and tradition that make the festival so special. She will wear a white Kerala kasavu saree with a gold border to embrace Kerala's elegance and heritage.
“The highlight of our celebration will be a circular flower decoration by the entrance called a ‘Pookalam’. I will be hosting a traditional Onam Sadhya, served on banana leaves with a number of vegetarian dishes followed by sweet dishes.
“For me, Onam is about recreating my childhood via new memories and keeping our cultural traditions alive by passing these customs onto the next generation.”
From Isolation to a Shared ‘Tribe’
For Thanu Kurien, who works in the Indo-UK bilateral trade corridor and is an award-winning actor and storyteller, and has lived in the UK for over two decades, Onam is deeply connected to her memories of Kerala and her journey in Britain.
“Growing up in Kerala, Onam was one of the best holidays, the big sadhya on banana leaves, and making attapoo for school competitions. When I first moved to the UK, Onam felt lonely and I’d scroll through family photos feeling very left out. But once I found my Malayalee tribe here, everything changed. We recreate the food, the laughter and the chaos. This year we’re taking some non-Indian friends to the Malayali Association Onam Sadhya, joining hundreds for food, friendship, entertainment. Next year, I’m hoping to go outside London and catch the boat races too.”
From Community Halls to Westminster
Over the past two decades, grassroots connections have transformed Onam in the UK from private living-room dinners into major public and civic celebrations.
At Westminster, cross-party Parliament receptions in the Jubilee Room bring together MPs, diplomats and community leaders. Featuring ceremonial Nilavilakku lamp lighting, pookalam displays and banana-leaf feasts, these events reflect the Malayali diaspora’s growing presence in British healthcare, business and public life.
Across the country, regional organisations run extensive calendars to accommodate shift workers and diaspora families. In London, the Malayalee Association of the UK (MAUK), the nation’s oldest Malayali organisation, hosts its flagship Ponnonam celebration at Eastbury Community School in Barking, featuring the annual MAUK Awards and vibrant cultural stage shows.
Major events such as Dhe Maveli Londonil at Byron Hall in Harrow draw thousands with performances by visiting Keralite artists, comedy troupes and traditional Thiruvathira group dances. Outside the capital, organisations such as the Milton Keynes Malayali Association (MIKMA) use large sports venues to host full-day gatherings combining large-capacity Sadya sittings, youth showcases and competitive vadamvali tournaments.
Central London restaurants are also bringing Onam to a wider audience. At Mayfair’s Jamavar, Leelamma’s Onam Sadhya, a 21-dish feast curated by Michelin-starred chef Surender Mohan, Culinary Director and Executive Chef, will be served from 17 to 31 August. A fully vegetarian version is also available, reflecting the restaurant’s contemporary interpretation of the traditional feast.
Whether marked by a ceremonial lamp inside the Houses of Parliament or a feast shared among friends in a suburban dining room, Onam across Britain remains a powerful expression of cultural continuity, showing that home can be built wherever you land.
