Market Overview

The United Kingdom water treatment systems market is described to the business focused on the integration and utilization of equipment and machinery to purify, filter, and treat water and supply it more purely. This market encompasses a range of treatment methods such as reverse osmosis, distillation, filtration, and disinfection to ensure water quality and safety. Water treatment systems perform a vital role by purifying wastewater to help restrict the spread of contamination resources. Drinking water can be treated at a central processing plant, at houses or other distribution sites, or the source before being made available to consumers. The development of pathogen-caused waterborne infections is one of the biggest public health issues which highlighting its significant needs. Because it is less costly, underdeveloped nations usually simply employ one treatment method, like chlorination, which only eliminates some of the pollutants, including heavy metals and other variables. The UK Government announced £11.5 million in extra funding to support 180 local projects aimed at improving water quality, tree planting, habitat restoration, and flood management across England. This funding, part of the Water Environment Improvement Fund (WEIF), is expected to unlock an additional £11.5 million from various organizations, bringing the total potential investment to £23 million.

Driving Factors

The market for United Kingdom water treatment systems is flourishing due to the growing development and industrialization across the country. The desire for clean and pure water is increasing in every sector that relies on water systems and focuses on smart cities. Additionally, to efficiently treat wastewater and meet the rising demand for clean water, local regulatory bodies are introducing and enforcing contemporary water treatment systems. The market expansion for water treatment systems in India is mostly driven by the Internet of Water system. IoT is a disruptive force for water treatment utilities because, in these water-scarce times, it gives those living in isolated and remote regions a steady supply of water.

Restraining Factors

The market for water treatment systems in the UK suffers significant challenges, including accessibility problems and gaps in the infrastructure, high cost of running and maintaining water treatment plants. For small and medium-sized businesses with tight budgets, this makes it difficult for them to continuously invest in the newest and most effective water treatment technologies.

Market Segmentation

The United Kingdom water treatment systems market share is classified into technology, installation, and application.

• The RO systems segment accounted for the highest share in 2024 and is anticipated to grow at a significant CAGR during the forecast period.

The United Kingdom water treatment systems market is divided by technology into water softeners, filtration systems, disinfection systems, RO systems, distillation systems, and others. Among these, the RO systems segment accounted for the highest share in 2024 and is anticipated to grow at a significant CAGR during the forecast period. This is because they dissolved or suspended bacterial and amoebic particles in water can be eliminated using reverse osmosis and filtration with carbon and sediment. Moreover, the RO system eliminates dirt, debris, foul taste, and chlorine through the distillation system section. Besides, they only generate a limited volume of treated water, distillation units are placed as point-of-use devices at the faucet rather than being utilized to treat all of the water entering the house.

• The POE (point-of-entry) segment held a significant share in 2024 and is expected to grow at a rapid pace over the forecast period.

The United Kingdom water treatment systems market is differentiated by process into POU (point-of-use), and POE (point-of-entry). Among these, the POE (point-of-entry) segment held a significant share in 2024 and is expected to grow at a rapid pace over the forecast period. This is because the main advantages of PoE for small communities include easier implementation, simpler maintenance and operation, and speedier and less expensive installation. Further, in individual business enterprises, including lodges, hotels, restaurants, schools, and other public buildings, the PoE water treatment technology could drive the significant revenue scale.

• The commercial segment held the highest share in 2024 and is expected to grow at a significant CAGR during the forecast period.

The United Kingdom water treatment systems market is segmented by application into residential, commercial, industrial, and others. Among these, the commercial segment held the highest share in 2024 and is expected to grow at a significant CAGR during the forecast period. This is because it lowers the risk of water-borne diseases such as cryptosporidiosis and cholera, increases consumer awareness of health issues, which has a significant impact on the adoption of water treatment technology. to stop the spread of waterborne illnesses. Also, the water treatment requirements of establishments that use large volumes of high-quality water, such as malls, offices, retail stores, restaurants, hotels, manufacturing facilities, schools, and labs, propel the segment growth.
