Harvey Water Softeners UK: Models, Prices and What to Expect

Every Harvey softener is built around the same idea: two resin cylinders and no electricity. While one cylinder softens your water, the other regenerates, so soft water is available 24 hours a day with no hard-water gaps. Regeneration is triggered by the amount of water you actually use, measured mechanically, rather than by a timer.

Because the softening needs no power, there are no clocks to reset after a power cut, no electricity cost and very little to manage. Harvey also designs its softeners not to need routine servicing, so in most homes the only regular job is topping up the salt. For households that use water at unpredictable times, the combination of continuous soft water and minimal upkeep is the main reason Harvey remains so popular.

• HarveyArc: Harvey's flagship domestic softener for homes with 1 to 3 bathrooms. Compact (438mm deep, 202mm wide, 487mm high), 56 litres per minute flow, 3,000 litre capacity and 1 to 10 bar working pressure. Uses shuttle metering to measure every drop, runs on Mini Curve block salt, and has been tested to over 1 million cycles. Made from 62% recycled plastic.
• Smart HarveyArc: the HarveyArc with the Wi-Fi i-Lid, which links to the myHarvey app to monitor salt levels and reorder salt, and works with Amazon Alexa.
• HVX and Big Blue: Harvey's softeners for larger, higher-demand households.
• TwinTec range (S4, Cobalt): Harvey-made twin-cylinder softeners supplied through the TwinTec distributor network. Warranty terms are set by the distributor and model, so check them with the supplier.

Harvey guide prices run from around £500 to £2,000+, depending on the model, the capacity your home needs and what the package includes, plus installation where it isn't included. Treat these as guide prices: your actual price depends on your household size, water hardness, plumbing and the options you choose, such as the smart i-Lid or a drinking water tap.

Harvey offers free consultations online or in person, finance at 0% representative APR, and a trade-in route for customers replacing an older softener of any brand. Comparing quotes from vetted installers is also a quick way to see what a Harvey would cost for your home and how it stacks up against other leading brands.

The HarveyArc comes with a 3-year manufacturer warranty covering parts and labour. Before it ends, Harvey contacts owners about extending cover by another 7 years, giving up to 10 years of protection in total.

Harvey also offers a 90-day money-back guarantee (terms apply). That's rare in the softener market and gives you three months to judge the difference for yourself.

For extra peace of mind, optional ArcCare plans add an annual inspection, clean and optimisation by a Harvey water expert, plus 20% off your annual salt supply. ArcCare is separate from, and additional to, the manufacturer warranty and your statutory rights. Harvey recommends using Harvey salt, as lower-quality salt can affect performance and warranty cover.

Because Harvey softeners are non-electric, the main running cost is salt, typically a few pounds a month for an average household. The HarveyArc uses Mini Curve block salt, which is lighter than standard blocks and shaped to make the most of the cabinet space. Solid blocks give clean brine and avoid the bridging and mushing that loose tablet salt can cause.

Salt is available in multi-packs from Harvey's online shop, and Smart HarveyArc owners can track levels and reorder through the myHarvey app. Since the softener only regenerates when you've used enough water to need it, salt and water aren't wasted on unnecessary cycles. Over time, owners also benefit from less limescale on taps, showers and appliances, lower cleaning product use and more efficient heating.

Harvey owners consistently rate the product highly for reliability and ease of living with it. The points that come up most often are quiet operation, no programming or settings to manage, soft water at any time of day, and a unit small enough to disappear into a kitchen cupboard.

Many owners have run Harvey softeners for well over a decade, and the brand's long-standing UK service network means support is available across the country. Read our Harvey water softener reviews for owner feedback in more detail.

Before you buy, check three things. First, sizing: the model should match your number of bathrooms, household size and local water hardness. Second, what's included: installation, valves, fittings, a drinking water tap and removal of any old unit. Third, cover: the warranty term, the money-back guarantee and any aftercare plan.
