The Government is considering measures to tackle leaking toilets as part of wider efforts to reduce water waste and improve efficiency across Britain’s homes and buildings.
According to an article in The Telegraph, published on Saturday, May 23, officials at the Department for Environment, Food and Rural Affairs have convened a “leaky loo taskforce” to examine how hundreds of litres of water a day are being lost through faulty toilet systems.
One option under consideration is action on European Union dual-flush valve toilets, which were introduced to reduce water use but have been criticised for being more prone to leaks than traditional UK syphon systems. A government source told the newspaper that there were no confirmed plans for a ban “at this stage”.
Dual-flush toilets are widely marketed as water-saving products, typically offering a lower-volume half-flush and a larger full-flush. However, concerns have grown that some valve-based systems can leak continuously into the pan when seals deteriorate, often without householders noticing.
By contrast, traditional syphon systems lift water over a bend using suction. Supporters argue this makes them inherently resistant to leaks, as the water level in the cistern does not rise above the syphon bend. However, this must be weighed against the growing popularity of concealed products installed behind walls or within furniture, which present their own challenges. The industry is investing heavily in developing more leak-resistant solutions, but bringing options to market that meet expectations on price and design will take time.
The issue is significant for water efficiency. The Consumer Council for Water has estimated there are around 3.6 million leaking toilets in Britain, with each potentially wasting up to 400 litres of water per day. Waterwise has also estimated that 8% of UK toilets are leaking.
The debate comes as the Government is under pressure to meet legally binding targets to halve leakage by 2050 and reduce per-person water consumption by 20% by 2038. The Environment Agency has also said water efficiency should be treated as a national priority.
Bathroom and plumbing manufacturers have argued that post-Brexit regulatory freedoms should be used to reconsider the rules that enabled wider adoption of valve-based systems. Mark Morris, of Thomas Dudley, told The Telegraph that Britain previously had “the best toilet systems in the world” and said a return to syphon cisterns could save significant volumes of treated drinking water.
John Pearce, chief executive of Made in Britain, also backed reform, arguing that regulation should raise standards rather than permit systems that increase leakage risk.
The issue is likely to attract further attention as household water bills rise and policymakers seek practical ways to reduce waste, protect supplies and support long-term water resilience.
