Before you get to the door of a grocery store on Southall Broadway on a weekday afternoon, you will hear three different languages. The shelves inside are filled with goods that were brought in through import networks that were established over many years, such as family contacts in Punjab, distributors in Dubai, and WhatsApp groups that run in both Urdu and English at the same time. This isn’t unofficial trade. It operates out of a shop front the size of a studio apartment and is, in its own quiet way, a sophisticated trading operation.
Bilingual small businesses in London rarely make the news. They don’t have venture capital backing. They don’t deliver TED talks. However, borough by borough, they are accomplishing something that big businesses pay hefty consulting fees to imitate: creating real trust across linguistic divides and turning that trust into profits. SMEs make up more than 99 percent of all businesses in London, and a disproportionate number of independent high street operators are bilingual and foreign-born. It’s not a footnote. That is how the street-level commercial life of the city is organized.
Walking through areas like Peckham or Tower Hamlets gives one the impression that what appears to be a local economy is actually much more interconnected. In addition to serving the local community, a Bangladeshi-owned textile supplier in Whitechapel might be sourcing from factories in Dhaka, fulfilling orders from buyers in Birmingham, and managing negotiations that, depending on who is on the phone, flow smoothly between Bengali and English. The business model does not rely on bilingualism. It is frequently the business model. It is what enables the proprietor to conduct business in markets that a monolingual rival just cannot reach as quickly or fluently.
Although it is rarely expressed that way, the economic reasoning behind this is actually quite simple. No amount of money spent on market research can fully replace a company’s ability to communicate authentically with a diaspora community in its language, with cultural literacy regarding its purchasing habits and trust signals. This may contribute to the remarkable resilience of immigrant-founded businesses in London during economic downturns. A type of customer base that doesn’t disappear the instant a less expensive option appears online is created by community loyalty, which is partially fostered by language.

The Greater London Authority has begun to monitor this more closely. Since its launch in early 2024, the Grow London Local program—which is administered by London & Partners and supported by £8.7 million in Mayoral funding—has reached over 250,000 entrepreneurs, with 88% of those recipients coming from communities that face additional challenges. When a business owner’s first language isn’t English and the support system wasn’t created with them in mind, it can be extremely difficult to navigate English-language regulatory processes, access funding applications, and comprehend tax obligations. The program’s reach indicates actual demand. It also implies that mainstream business support infrastructure has historically underutilized a large share of London’s entrepreneurial energy.
The social role these companies play is more difficult to measure, but it’s still real. A Polish delicatessen in Ealing, a Turkish bakery in Stoke Newington, and a Nigerian-owned hair salon in Peckham are all locations where a newcomer to the city can enter and temporarily feel less lost. Some of the friction associated with migration is absorbed by these businesses. Practically speaking, they are community infrastructure because they run profitably, without subsidies, and maintain the commercial viability of local streets.
It’s difficult to ignore how frequently this contribution is abstracted into GDP contribution figures for SMEs without anyone pausing to consider the real factors that drive these companies. A significant portion of the response is linguistic. Additionally, mainstream retail has continuously undervalued the willingness to serve communities. It remains to be seen if London’s institutions will become more adept at identifying and promoting that combination. However, the companies themselves aren’t holding out for praise. They are building trade corridors that most economists wouldn’t even consider mapping, answering calls in two languages, and opening early and closing late.
