Pioneering change in Great Britain’s water supply network.
Calisen and Advizzo are transforming how water is managed in homes and businesses across Great Britain and beyond. From smart metering to real-time insights, we help water companies reduce waste, empower customers, and optimise operations.
The UK's water challenge
Demand on the network
Climate change, population growth, and migration patterns are placing unprecedented pressure on the UK’s water supply. The South and South East are particularly at risk.
The Environment Agency warns that, without urgent action, England could face a daily water shortage of 5 billion litres by 2055 - around a third of today’s demand (The National Framework for Water Resources 2025). Ageing infrastructure and hidden leaks in homes only make the problem worse, often going undetected for years.
At Calisen, we integrate advanced data analytics with behavioural science to drive measurable outcomes. In one deployment, this approach reduced consumption by 3.5 mega-litres per day. A saving equivalent to approximately two Olympic-sized swimming pools every day. Ben Etherington

An opportunity for significant change
Transforming the water sector with smart technology
The water sector is undergoing one of its biggest transformations since privatisation. With rising customer bills, environmental challenges, and ageing infrastructure, water companies are embracing innovative solutions to secure the future.
Smart metering is at the heart of this transformation. By 2030, water companies aim to install 10.4 million smart meters across England and Wales, helping households and businesses monitor usage, detect leaks, and drive water efficiency.
Paired with Advizzo’s customer engagement platform, smart meters provide real-time, granular insights, maximising efficiency and delivering a better customer experience.
Our approach
Delivering complex programmes with confidence for over 20 years
Rolling out smart water meters at scale is complex and costly, often a first for water companies. Partnering with Calisen means:
We manage large-scale smart meter programmes with expertise and proven supply chain partnerships.
Our Funded Data as a Service (FDaaS) model spreads investment over time and transfers risk, reducing strain on budgets and minimising the impact on customer bills.
Beyond meters, our solutions boost networks with sensors and data platforms, creating smarter, more sustainable water systems.
