Is there a legal requirement to fit a water softener?

The short answer is no. But let’s get into the long, nuanced answer.

The Building Regulations 2010 Conservation of fuel and power Part L (Volume 1: Dwellings) stipulate that ‘In hard water* areas, suitable measures should be taken to treat the feed water to water heaters and the hot water circuit of combination boilers to reduce limescale accumulation.’ (section 8.8). Limescale accumulation can lead to poor energy performance, higher energy costs and an increased chance of failure in appliances and heat exchangers – leading to even bigger bills!

The simple remedy? Fit a Harvey Water Softener.

• Save up to £1,100 per year across your bills, shopping, and maintenance depending on your location in the UK.
• Stop limescale at the source and reduce your energy bills.
• Keep your appliances running and lasting longer.
• Soft on skin and hair, say goodbye to hard water irritation.

We suggest that if your water hardness is indicating levels of or over 100ppm, you could benefit from a water softener. To understand the difference it could make in your home book a demo now or if you’re unsure if your water is hard? check your water hardness here for free.

Did you know? there are also different expressions for how hardness is measured such as PPM, GPG or °Clark, read more here.

*Within the document, Hard water is defined as water which has a high mineral content and for the purposes of the approved document, hard water is water that has a total water hardness of greater than 200ppm of CaCO3.
