St Patrick's Day Office Catering London: 17 March Irish Celebrations

St Patrick's Day on 17 March is the feast day of Ireland's patron saint and the national day of Ireland, observed in Irish communities worldwide. In London — home to one of the largest Irish diaspora communities outside Ireland — it is one of the most widely marked cultural occasions of the year. This post covers the history of the day, the food and drink traditions associated with it, the Irish presence in London's professional life, and how a City office can mark it with a team event that reflects its genuine cultural character.

The origins of St Patrick's Day

St Patrick is the patron saint of Ireland, credited with bringing Christianity to the island in the fifth century. The historical Patrick was a Romano-British Christian missionary who, according to traditional accounts, was kidnapped from Britain as a teenager and taken to Ireland as a slave, escaped after several years, and later returned as a bishop to spread Christianity. He died around 461 AD, and 17 March is believed to be the anniversary of his death.

St Patrick's Day has been observed as a feast day in the Catholic and Anglican churches for centuries. In Ireland it developed into a national public holiday — one of the few days in the liturgical calendar when the Lenten fast was traditionally relaxed, which may explain the association with celebratory eating and drinking that developed over time.

The large-scale public celebration of St Patrick's Day outside Ireland is strongly associated with the Irish diaspora, particularly in the United States, where Irish immigration from the nineteenth century onwards created communities that maintained and amplified the occasion. The New York St Patrick's Day parade, first held in 1762 by Irish soldiers serving in the British Army, is now one of the largest parades in the world. The tradition of grand public parades spread to other cities with large Irish communities, including London, Dublin (where the parade was actually relatively modest until the late twentieth century), Sydney, and Melbourne.

Food and drink traditions associated with St Patrick's Day

The food traditions of St Patrick's Day vary considerably between Ireland, the Irish diaspora, and the broader global adoption of the occasion:

In Ireland — the traditional meal associated with St Patrick's Day is boiled bacon (cured pork collar or loin) with cabbage and potatoes; lamb stew is also associated with the occasion in some regions. The "corned beef and cabbage" dish most associated with the day in the United States is largely an Irish-American invention, developed by Irish immigrants who substituted the cheaper and more widely available corned beef for the bacon of home
Soda bread — Irish soda bread, leavened with bicarbonate of soda rather than yeast, is one of the most distinctive products of Irish baking; it is made in both white (blaa or white soda) and wholemeal (brown soda) forms
Irish stew — a simple preparation of lamb or mutton with potatoes, onion, and sometimes carrots; traditionally a dish of necessity rather than celebration, but now strongly associated with Irish cultural identity
Colcannon and champ — mashed potato dishes incorporating kale or spring onion respectively; classic Irish side dishes that feature at festive meals
Barmbrack — a yeasted fruit bread traditionally associated with Halloween in Ireland but eaten at various festive occasions

The Irish community in London

London has had a significant Irish population since at least the seventeenth century, and large-scale Irish migration to the city continued through the nineteenth and twentieth centuries. The post-war rebuilding of London, and the construction boom of the 1950s and 1960s, was substantially powered by Irish labour. Subsequent waves of migration brought Irish professionals to the city's financial, legal, healthcare, and technology sectors.

The Irish community in London is now multigenerational. Many Londoners of Irish heritage are second or third generation, with strong cultural connections to Ireland that do not depend on personal immigration. St Patrick's Day in London reflects this: it is observed by recent arrivals, long-settled families, and many non-Irish Londoners who have absorbed the occasion through proximity and friendship.

London's St Patrick's Day celebrations typically include a parade in Trafalgar Square and events across the city, usually held on the Sunday nearest to 17 March, though office celebrations can take place on the day itself if it falls on a weekday.

St Patrick's Day as a January office event

St Patrick's Day falls at a useful point in the office calendar. March is past the post-Christmas slump and before the Easter disruption, making it a natural moment for a team event. For offices with Irish colleagues — common in City banking, legal, and professional services — it is an occasion with genuine personal resonance.

Practical considerations:

St Patrick's Day 2027 falls on Wednesday 17 March — a mid-week working day, ideal for a team lunch
Warming, substantial food works for March; the occasion lends itself to hearty, satisfying dishes rather than light summer fare
A shared, communal format — large platters, shared sides — reflects the convivial spirit of the occasion better than individual boxes
Catering that meets the full range of dietary requirements (certified halal, allergen-labelled, strong vegetarian options) ensures all colleagues can participate

Frequently asked questions

Who was St Patrick and why is he associated with Ireland?

St Patrick was a fifth-century Romano-British Christian missionary credited with bringing Christianity to Ireland. According to traditional accounts, he was kidnapped as a teenager and enslaved in Ireland before escaping and later returning as a bishop. He died around 461 AD and 17 March — the anniversary of his death — is observed as his feast day. He is venerated as the patron saint of Ireland in both the Catholic and Anglican churches.

Why is corned beef associated with St Patrick's Day, particularly in America?

Corned beef and cabbage is largely an Irish-American dish rather than a traditional Irish one. In Ireland, the comparable dish is boiled bacon (cured pork) with cabbage and potatoes. Irish immigrants to the United States in the nineteenth century found pork expensive or unavailable and substituted corned beef, which was cheaper and widely sold by Jewish butchers in working-class New York neighbourhoods. The dish became a symbol of Irish-American identity and was later re-exported as a St Patrick's Day tradition.

How large is the Irish community in London?

London has one of the largest Irish diaspora communities in the world. Estimates of the number of London residents of Irish birth or heritage vary, but the community is substantial and multigenerational, concentrated particularly in areas such as Kilburn, Cricklewood, Hammersmith, and Islington, as well as being widely dispersed across the professional workforce. Large-scale Irish migration to London occurred in multiple waves from the nineteenth century through the late twentieth century.

What is soda bread and why is it associated with Irish food culture?

Irish soda bread is a quick bread leavened with bicarbonate of soda and buttermilk rather than yeast, which means it requires no proving time and can be made quickly with minimal equipment. It developed in Ireland in the nineteenth century when bicarbonate of soda became available, and became a staple of Irish rural kitchens. It is made in white and wholemeal forms and is strongly associated with Irish home baking, appearing at meals and celebrations as a matter of cultural habit.
