For millions of British families, the weeks before Diwali are the busiest of the year. Homes are cleaned and decorated, gifts are bought for relatives and colleagues, new outfits are ordered and kitchens fill with sweets and savouries. From Leicester’s Belgrave Road — home to one of the largest Diwali celebrations outside India — to Southall, Wembley, Birmingham and Manchester, high streets light up for the festival.

Yet many UK businesses still plan their autumn around Halloween and Black Friday alone. That leaves real value on the table.

When is Diwali 2026?

Diwali itself falls on Sunday 8 November 2026, within a five-day festival that begins with Dhanteras — traditionally an auspicious day to buy gold, silver and household items — and ends with Bhai Dooj. For Sikhs, the same day marks Bandi Chhor Divas. Diwali is not a UK public holiday, so many families celebrate across the surrounding evenings and the weekend.

Why does Diwali matter for UK businesses?

The UK is home to one of the largest Indian diaspora communities in the world, and Diwali is the community’s biggest celebration of the year. Spending is concentrated in a short window and across several categories at once:

• Jewellery and gold — especially around Dhanteras
• Fashion — new outfits for family events and temple visits
• Food and sweets — mithai boxes, catering and restaurant bookings
• Gifting — hampers, homeware, electronics and corporate gifts
• Home and décor — lights, diyas, rangoli and home improvement
• Travel and hospitality — family visits and celebratory dining

Increasingly, mainstream brands and supermarkets run dedicated Diwali ranges, and more British businesses send Diwali greetings to clients and staff. Recognising the festival is no longer niche; it is part of good customer and employer relations in modern Britain.

How can small businesses make the most of Diwali?

1. Plan early. Diwali shoppers buy in the two to three weeks before the festival. Stock, staffing and promotions need to be ready well before the day itself.
2. Be authentic. Customers notice tokenism. Learn the basics — greetings such as “Happy Diwali” or “Shubh Deepavali”, what people buy and why — and involve staff or partners from the community.
3. Make checkout effortless. Peak periods expose weak payment set-ups. Contactless, card-not-present and quick online checkout matter, as do clear delivery cut-off dates for gifts.
4. Think gifting, not just discounts. Curated gift boxes, corporate hampers and gift cards often outperform price cuts during festive seasons.
5. Connect Diwali to the wider season. Diwali leads naturally into Christmas trading. Customers who discover you in early November can become regulars through December.

Diwali across the Commonwealth

Diwali is a public holiday in several Commonwealth countries, including India, Singapore, Malaysia, Mauritius, Fiji, Guyana, Trinidad and Tobago, and Sri Lanka. For businesses that trade internationally, that matters: supply chains, customer service and payment volumes in these markets all shift around the festival — a useful reminder that cultural calendars are also business calendars.

Ask most people what the Commonwealth is and they will mention the Commonwealth Games or the King. Ask a business owner and the answer is often a shrug. Yet the Commonwealth covers some of the world’s fastest-growing markets — and for UK firms looking beyond Europe, it is one of the most useful maps there is.

What is the Commonwealth?

The Commonwealth of Nations is an association of equal, independent member countries that work together on shared goals such as democracy, development, trade and the rule of law. Membership is voluntary, and most — but not all — members have historic ties to Britain. Gabon and Togo, which had no such ties, joined in 2022.

King Charles III is Head of the Commonwealth. Its work is supported by the Commonwealth Secretariat, led by Secretary-General Shirley Botchwey, and leaders meet every two years at the Commonwealth Heads of Government Meeting (CHOGM). The 2026 summit, in Antigua and Barbuda, is focused on partnerships and investment.

Which countries are in the Commonwealth?

According to the Commonwealth Secretariat, the 56 members are spread across five regions:

Thirty-three members are classed as small states — usually with populations under 1.5 million — and 25 of these are small island developing states.

What is the “Commonwealth advantage” for business?

The Commonwealth has no single free trade agreement, but members share features that reduce friction: English as a common working language, similar legal and accounting systems, familiar institutions and strong diaspora links. The Commonwealth Secretariat estimates bilateral trade costs between members are on average 19% lower than between non-members; the Commonwealth Enterprise and Investment Council puts the figure at around 21%.

Combined Commonwealth GDP was US$13.1 trillion in 2021, according to the Secretariat, and is projected to grow strongly through the decade — driven by large, young economies in Asia and Africa.

How can UK businesses use the Commonwealth network?

• Use bilateral trade deals. The UK has agreements with several members, including Australia, New Zealand, Canada and India.
• Follow the business forums. The Commonwealth Business Forum, held alongside CHOGM, connects firms with ministers and investors.
• Tap diaspora networks. Business councils and community organisations in the UK often have direct links into home markets.
• Join trade missions. Government and business-council delegations offer introductions that are hard to arrange alone.

Frequently asked questions

How many countries are in the Commonwealth?

There are 56 member countries in the Commonwealth: 21 in Africa, 8 in Asia, 13 in the Caribbean and Americas, 3 in Europe and 11 in the Pacific.

Is the Commonwealth a trading bloc?

No. The Commonwealth has no single free trade agreement, but shared language and legal systems lower trade costs between members, and many members have bilateral trade deals with each other.

Who leads the Commonwealth?

King Charles III is Head of the Commonwealth. The Commonwealth Secretariat is led by Secretary-General Shirley Botchwey, and heads of government meet every two years at CHOGM.

London, UK — 1 November 2026

The 28th Commonwealth Heads of Government Meeting opens today in St John’s, the capital of Antigua and Barbuda, bringing together heads of government, ministers and representatives from business, civil society and youth organisations. Antigua and Barbuda is the smallest country ever to host CHOGM, and the summit coincides with the nation’s 45th anniversary of independence on 1 November.

It is also the first CHOGM convened by Commonwealth Secretary-General Shirley Botchwey, who took office in April 2025. “The world is changing and CHOGM 2026 is our moment to shape what comes next,” she said ahead of the summit.

Why is this CHOGM focused on investment?

The theme, “Accelerating Partnerships and Investment for a Prosperous Commonwealth”, reflects a deliberate shift towards practical economic outcomes. According to the Commonwealth Secretariat, CHOGM 2026 will for the first time bring government and business leaders together specifically to unlock investment.

On 20 October the Secretariat launched the Commonwealth Investment Platform, showcasing more than 60 high-impact projects submitted by 20 Commonwealth countries that are seeking financing. The Secretary-General has made support for small states, least developed countries and other vulnerable economies a key pillar of her leadership.

Host Prime Minister Gaston Browne set the tone at the summit’s launch: “Antigua and Barbuda is proud to open our doors to the Commonwealth in 2026 — to host, to listen, and to lead with purpose.”

What happens at the Commonwealth Business Forum?

The 14th Commonwealth Business Forum runs from 2 to 4 November at the Sticky Wicket cricket ground, hosted by the Commonwealth Enterprise and Investment Council (CWEIC) with the Government of Antigua and Barbuda and the Commonwealth Secretariat. CWEIC expects more than 900 delegates, including representatives of Afreximbank, the International Monetary Fund, the World Trade Organization, Royal Bank of Canada, De La Rue and Fortescue.

CWEIC describes the Commonwealth as a market of 2.7 billion people with a combined GDP of more than US$13 trillion, and says the cost of doing business between member countries is on average 21% lower, thanks to shared language, legal systems and regulatory traditions. The forum includes a business-matching system for pre-arranged one-to-one meetings, aimed at turning high-level discussion into deals.

King Charles III, as Head of the Commonwealth, will address the summit’s opening ceremony on 3 November and is also due to attend the Business Forum. Alongside the leaders’ meetings, the programme includes Youth, Women’s and People’s Forums.

What else is on the table?

UK Prime Minister Andy Burnham is attending. Caribbean leaders are expected to raise slavery and reparatory justice, although these are not formally on the agenda. Mr Burnham has said he is open to hearing calls for a formal apology but has ruled out financial reparations, a position Caribbean leaders have rejected.
