Private single-sex girls’ schools in the United Kingdom are facing a marked decline, with projections suggesting they could disappear entirely within the next 50 years if current trends continue. This forecast is based on declining pupil numbers, shifting parental preferences toward co-educational settings, and financial pressures affecting the independent education sector.

Data spanning the past 15 years indicates a significant reduction in the number of private girls’ schools. According to recent analysis of government education figures and Independent Schools Council censuses, the number of such institutions has dropped from 186 in 2011 to 142 in 2026, a decrease of approximately 23 percent. This represents an average loss of nearly three schools per year. By contrast, all private schools have experienced a smaller overall decline during the same period, dropping from 2,415 in 2011 to 2,311 in 2026. Boys’ independent schools have also declined, though at a slower rate, falling from 117 to 86 over 15 years.

If these patterns persist, projections suggest fewer than 100 private girls’ schools will remain shortly after 2040 and that single-sex girls’ schools could be extinct by 2079. Boys’ schools may face a similar fate by the end of the century. Julie Keller, headmistress of Nottingham Girls’ High School, emphasized the continuing relevance of girls’ schools, warning that their disappearance could adversely affect future opportunities for women and girls.

Several factors are contributing to this decline. Falling enrollment numbers are a primary driver, with the overall independent school pupil population decreasing from 576,220 in 2011 to 560,255 in 2026. Smaller girls’ schools appear particularly vulnerable to these shifts, often resulting in closures or transitions to co-educational models. For instance, Dunottar School for Girls in Surrey began admitting boys in 2014, and Malvern St James in Worcestershire introduced co-education in 2025 before ultimately closing in 2026 amid financial difficulties.

The introduction of a 20 percent value-added tax (VAT) on school fees by the Labour government in January 2023 has placed additional financial stress on private schools, with over 100 schools reportedly closing since the levy’s implementation.

Changing societal attitudes also play a role. Keller noted that many parents, having themselves been educated in co-ed environments, prefer similar settings for their children. She acknowledged a persistent perception that girls’ schools are outdated, which may contribute to declining demand. However, she contended that girls’ schools remain highly relevant in an era when gender equality has yet to be fully achieved.

Despite the challenges facing single-sex private education, advocates maintain that these schools continue to provide important environments that support the academic and personal development of girls. The trajectory of girls’ schools, however, remains uncertain amid evolving educational preferences and financial constraints.
