A new UK survey has found a clear gap between public awareness and behaviour when it comes to household cleaning products. While most Britons believe bleach may pose risks to health or the environment, it remains widely used in homes across the country.
The research, commissioned by eco cleaning brand Delphis Eco and conducted among 1,000 UK adults, shows that 88% of respondents continue to use bleach. This is despite a widespread perception that the product can be harmful.
Bleach is not banned in the UK or the EU and continues to play a role as a disinfectant in domestic and commercial settings. Its use is regulated due to its hazardous properties, with guidance in place to reduce risks associated with handling and exposure.
Health concerns linked to bleach are well documented. It can irritate the skin, eyes and lungs, and may worsen respiratory conditions such as asthma. There are also safety risks when bleach is mixed with other cleaning products, as this can release toxic chlorine gas.
Environmental impacts are also part of the debate. When discharged into wastewater systems, bleach can harm aquatic life and disrupt beneficial bacteria. It may also form chlorinated compounds when it reacts with organic matter, raising further concerns about its long term effects on water systems.
Despite this, the survey points to what has been described as a “behaviour gap” between awareness and action. While many consumers recognise potential risks, this has not yet translated into a widespread shift away from traditional cleaning products.
At the same time, attitudes appear to be changing. Six in ten respondents said bleach should be used less frequently, indicating an increasing level of caution among consumers.
The findings also suggest a strong willingness to consider alternatives. Around 85% of those surveyed said they would switch to eco-friendly cleaning products if they believed these options performed as effectively as bleach.
This points to performance perception as a key barrier to change. While awareness of environmental and health issues is rising, confidence in alternative products remains a deciding factor for many households.
Generational differences are also evident in the data. Younger consumers show higher levels of concern about the impacts of bleach, with 45% of those aged 25 to 39 describing it as very harmful. This compares with 23% among those aged over 60.
These differences may reflect broader shifts in attitudes towards sustainability and product transparency. Younger demographics are often more engaged with environmental issues, which is influencing purchasing decisions across a range of sectors, including household cleaning.
Mark Jankovich, CEO of Delphis Eco, said: “This research shows a clear disconnect. The opportunity is now to turn awareness into action.
“Advances in modern cleaning formulations mean it’s now entirely possible to achieve high standards of hygiene and effectiveness without relying on harsh, toxic chemicals. Take our own products which are as good – if not better – than any bleach-based cleaning product yet without the harmful ingredients.
“The world is moving on from old households brands that do not look after the environment or invest in fresh innovation. And the industry needs to help consumers make that transition with confidence – by demonstrating that they don’t have to compromise on performance to make more sustainable choices.”
The survey results come at a time when regulatory scrutiny and consumer expectations around chemicals and environmental impact are increasing. Across Europe, legislation such as REACH places strict controls on hazardous substances, while broader policy frameworks are encouraging reduced environmental harm from everyday products.
Within this context, the cleaning products sector is undergoing gradual change. Manufacturers are investing in new formulations designed to meet hygiene standards while reducing toxicity and environmental impact. However, adoption at household level depends on consumer trust as much as product availability.
The UK market remains highly competitive, with established brands continuing to dominate shelf space. This can limit visibility for newer alternatives, particularly those positioned around environmental benefits rather than familiarity or price.
The findings suggest that awareness alone is not enough to drive behaviour change. While concerns about bleach are widespread, practical considerations such as perceived effectiveness and product recognition continue to influence decisions.
At the same time, the data indicates that the conditions for change are in place. With a large proportion of consumers open to switching, shifts in communication, product performance, and accessibility may play a key role in shaping future habits.
As awareness continues to grow, the balance between hygiene, safety and environmental impact is likely to remain a central issue for both consumers and manufacturers. The survey points to a market in transition, where longstanding habits are being reassessed but not yet replaced.
