most of the height statistics are outdated. and they always group in the oldies who bring the average down.

In 2009, the average height of regularly 19-year-old Swiss conscripts was 178.2 cm. Percentiles were P5 = 168 cm, P10 = 170 cm, P25 = 174 cm, P50 = 178 cm, P75 = 182 cm, P90 = 187 cm, and P95 = 189 cm. Over the course of the 130 years between 1878–79 and 2009 the average height of 19-year-old conscripts increased by a total of 14.9 cm. The distribution shifted upwards. In 1878–79, 5.48% of conscripts were 175 cm tall or taller, but only 0.89% were 180 cm tall or taller. In 2008–09, 71.13% of the conscripts were 175 cm tall or taller, and 41.69% 180 cm tall or taller. In recent decades, this trend has slowed markedly.
It probably isn't as tall as you think. I don't have the data for UK but here's a study with the average height of conscripts in the Swiss army (first graph on page 4).
And the conclusion from https://smw.ch/article/doi/smw.2011.13238/:
So height increases have plateaued.
So if the Swiss are not shorter than Brits, and given that conscripts are selected randomly, I'd say that the official average height stats are close enough.
