Mr Todd believes the Nigerian market is large enough to accommodate all the new schools without threatening existing ones. About 40% of the 200 million population is under 14. He expects the greatest impact to be felt in the UK. While Charterhouse UK typically has a long waiting list and should not be affected, less sought-after boarding schools may experience a decline in enrolment owing to the new competition in Nigeria. "Interest in our secondary school is very strong," says Mr Todd. "We already have Nigerian parents in the UK sending their children to the Charterhouse in Nigeria for September." In fact, reaching out to Nigerians in the UK has been one of their key marketing strategies. "You get this premier brand at a lower price, and every Nigerian has an aunt or uncle in Lagos" who can be a guardian, he adds. It could be that this trend extends to British universities. Nigeria's tertiary education system faces even greater challenges than its secondary sector, with many students opting to study abroad. In 2023, Nigeria ranked among the top 10 countries for UK student visas, according to UK government data. But with foreign exchange difficulties and stricter visa regulations, studying abroad is becoming increasingly challenging - and universities that rely on higher international tuition fees appear to be suffering. Earlier this month, British MP Helen Hayes, chair of the parliamentary Education Committee, acknowledged the UK's higher education sector was in trouble. "Dozens of universities are making redundancies and cuts to courses, trying to stay afloat amid uncertainty over where their money is coming from," she said when announcing a session to consider the sector's future. If enough Nigerian students can no longer go to the UK to study, British universities may find it profitable to come to them, as they have elsewhere in the world. In fact, Nigeria's premier university, the University of Ibadan, was established in 1948 as a campus of the University of London, with degrees awarded carrying the same value and prestige. Ms Uwakwe-Okoronkwo believes many Nigerian parents would appreciate this opportunity, as it would allow their children to stay in Nigeria long enough to mature before potentially moving abroad, if they choose to do so. "Many parents are worried about sending their children out of the nest too early," she says. For Ms Oyede, whose daughter will also be starting at Rugby School in Lagos come September, the timing of all this could not be better. She says the British school opening has already been an "incentive to return home". The prospect of university opportunities would be a welcome bonus.
