(Lime)scale of the problem: how softened water can help alleviate strain on household finances

2 min read

Our latest research has found that limescale could be costing households in hard water areas an extra £180 a year on heating. This is no small problem, with approximately half of UK households (a total of 13 million) currently suffer from hard water1 – use our Hard Water Index to find out how hard your water is.

Households with hard water can accumulate a staggering 1.5mm of limescale within their internal plumbing over a year, increasing average gas costs by 28 per cent2. Given that UK households spend on average £12.30 a week on fuel, limescale could be costing households in hard water areas a combined total of £2.3 billion a year3 4. Limescale deposits within heating systems can also cause blockages in pipework and boilers, reducing heating efficiency by 12% over a year5.

These findings demonstrate how limescale can cause a significant strain on, a problem exacerbated by a third national lockdown meaning people are spending more time in their own homes during the darker and colder winter months. And with wholesale energy prices predicted to rise in 2021, and the cold weather set to stay for some time yet, many households will need to be savvy to reduce their energy bills.

As well as disrupting household heating systems, limescale is a household menace when it comes to cleaning, causing difficult stains around baths and basins, sinks, toilet bowls and shower heads. It can also significantly shorten the lifespan of many expensive household products such as kettles and washing machines. Thankfully, it’s actually easier than you might think to get rid of, and you can remove limescale from appliances like your kettle in a number of different, simple-to-follow ways.

The best way to prevent limescale build-up is to prevent the hard water that causes limescale from being present in the first place. Installing a non-electric water softener is a simple and longer-lasting solution than any manual cleaning method out there. Water softeners draw out the magnesium and calcium ions which make water hard and limit the accumulation of scale and scum, preserving the efficiency of heating systems.
