The Horticultural Trades Association (HTA) and the British Association of Landscape Industries (BALI) are calling on the UK government to adjust the water restrictions. In a joint letter to Minister Emma Hardy, they warn that the current measures – such as South East Water’s temporary ban on water use following the heatwave – are causing unnecessary harm to businesses in the green sector. This sector, which represents 3,800 businesses, plays a crucial role in combating climate change through urban greening, flood prevention and heat resilience.

Fran Barnes (HTA): “Our sector uses just 0.15 per cent of the UK’s water, yet delivers enormous environmental and social value. Water restrictions must be proportionate and clear, so that we can create and maintain green infrastructure – such as trees, gardens and parks. As it stands, we risk undermining the very solutions for climate adaptation.”

The organisations are calling for a long-term water management strategy, developed in collaboration with the sector. They want a revised Code of Practice for Drought with better exemptions for horticulture and landscape management, and clearer communication about restrictions to prevent uncertainty for businesses.

During the heatwave in June, temperatures on London’s pavements reached 57°C – greening is essential to keep cities liveable. The sector itself can contribute to water conservation through rainwater harvesting, drought-resistant planting and efficient irrigation.
