Jersey Water to raise bills from 2026

Islanders can expect to pay more for their water from 2026, with Jersey Water confirming average annual bills will rise by just under £60 – and further increases likely in the years ahead.

The utility said the higher charges were necessary to help fund a £48m investment programme designed to secure the island’s water supply and improve resilience against future shortages.

Research carried out by the company indicates Jersey could face a shortfall of 8.6 million litres a day during severe drought within the next decade if action is not taken.

From January 2026, customers will see an average £59.48 added to their yearly bills, with the company warning of an “above-average increase” again in 2027.

Jersey Water chief executive Helier Smith acknowledged the strain on households already facing high living costs but said the investment was unavoidable.“Any increase in charges is unwelcome,” he said. “But the choice is clear – we must invest now to build resilience and protect supplies for the future.”

Major projects planned

The programme includes a 50% boost to desalination capacity, upgrades to ageing sections of the mains network, and work to cut leakages.

Chief water operations officer Mark Manton said the desalination plant, last upgraded in 2015, was vital for dry spells but in need of modernisation. “It doesn’t run every day,” he explained. “We bring it online only in the dry months, but this summer showed how important it is when reservoir levels drop.”

Tackling PFAS concerns

Alongside supply projects, about £2m has been set aside over the next two years for trials to address concerns about man-made chemicals known as PFAS in drinking water. The firm said “major changes” to treatment methods may be required, including the possibility of building a new facility.

PFAS, often described as “forever chemicals”, are found in everyday items such as non-stick pans, waterproof clothing and food packaging. A government-commissioned report in August recommended setting new limits for PFAS levels in the island’s drinking water.

Jersey Water said the long-term investment plan was designed not only to expand capacity but also to “future-proof” operations against both regulatory changes and the growing risk of climate-related droughts.
