About the School and Local Area

Queen Elizabeth Grammar School (QEGS) in Wakefield, West Yorkshire, is a leading independent school with a proud history dating back to its foundation in 1591. The school is well-regarded for academic excellence and strong community values, serving pupils across Wakefield and the wider Yorkshire region. Wakefield itself is a city with a rich industrial heritage and a reputation as a cultural hub, home to The Hepworth Gallery and surrounded by scenic Yorkshire countryside.

The school’s facilities are critical in supporting its commitment to providing first-class education and co-curricular activities. Maintaining safe, reliable, and modern infrastructure plays a key role in delivering this vision for current and future generations.
