If work at the Ladies Pond is completed on time, the mixed pond should be open for mixed swimming from April 5.
A spokesperson for the City of London Corporation, which manages Hampstead Heath, said: “Hampstead Heath is a cherished green space. We reinvest all income directly back into the charity to maintain and improve the array of facilities we have on the Heath.
“A modest increase — around 10p per swim — helps us cover rising costs and ensure the bathing ponds and lido remain safe, clean, and accessible for all.
“We remain committed to keeping the Heath’s swimming facilities affordable while preserving them for future generations to enjoy.”
