Families could soon face higher water bills under new proposals backed by Labour, with critics branding the plans a “bathtime tax” that targets traditional family homes. Water companies are seeking to introduce a new charging system that would see households using the most water pay the highest rates. And ministers under a Labour government have said they are open to the idea.

The plans would particularly affect homes with gardens, swimming pools, or more people living under one roof, such as families with young children. The move comes as firms look to introduce what they call “progressive” pricing. The system, also known as rising block tariffs, would increase the rate charged per litre the more water a household uses.

It would also mean higher bills during the summer, as some companies are pushing for seasonal pricing.

This would see water cost more in warmer months, when families typically use more for gardening, paddling pools, or additional showers and baths.

The proposals would require widespread installation of smart meters to track water usage in real-time.

The Government estimates that only around 12% of homes in England currently have such meters installed, though around 60 percent have traditional meters.

According to The Telegraph, Labour ministers have indicated support for trialling the new tariffs.

Water firms argue the model would cut down on consumption and could reduce bills for most people.

However, concerns have been raised that the changes would unfairly impact families and those with larger homes.

The Conservative Party has hit out at the plans, warning they could see parents punished simply for using water for everyday needs like bathtime or garden maintenance.

A Tory insider told The Telegraph the plans were “punitive” and accused Labour of waging “war on family homes”.

The changes are being considered as parts of the country face increased pressure on water supplies.

England recently recorded one of its driest starts to spring in almost 70 years, and the Environment Agency has declared a drought in the North West.
