Reverse osmosis (RO) systems had the largest revenue share in the UK residential water purifier market in 2024, due to their high efficiency in removing contaminants such as PFAs, lead, and microplastics. With rising concerns over tap water quality, RO's capability to provide multi-stage filtration has gained consumer trust. Their widespread availability across retailers reinforces their top market position.

According to 6Wresearch, the UK Residential Water Purifier Market is projected to grow at a CAGR of 4.2% from 2025-2031F. The UK residential water purifier market saw meaningful growth underpinned by macroeconomic and policy factors. Firstly, accelerating degradation in water quality—highlighted only England’s rivers meeting good ecological standards and sewage discharges in 2020—amplified consumer concern and demand for point-of-use purification.

Looking ahead, the UK Residential Water Purifier Market is expected to experience growth driven by a shift in public awareness and institutional response. In January 2025, the UK updated its PFAS for individual substances. Additionally, respondents YouGov survey believed that chemical manufacturers should be primarily responsible for reducing PFAS levels, who placed responsibility on the government. When breaches of the Water Quality Regulations occur, the DWI may require the responsible water company to implement a legally binding action plan to restore compliance. However, this system of post-incident corrective measures reinforces public reliance on regulatory responses and company assurances, often delaying proactive risk mitigation. This underscores the need for in-home solutions such as point-of-use filtration.
