Stockbridge is famous for its single wide High Street and the River Test, one of England’s finest chalk streams for trout fishing. The same chalk geology that makes the Test so clear and inviting is responsible for pushing local water hardness to around 235–245 PPM. The average reading sits close to 240 PPM, which places the town at about 82% on the hardness scale.
Those numbers might sound moderate compared to other parts of Hampshire, but 240 PPM is still firmly in the hard water category. The Water Quality Association classifies anything above 120 PPM as hard. Stockbridge is double that threshold.
Measuring the Real Cost
Hard water at 240 PPM deposits approximately 240 milligrams of dissolved minerals per litre. Over the course of a year, a typical four-person household uses around 150,000 litres. That’s roughly 36 kilograms of calcium carbonate passing through your plumbing annually. Some of it ends up as scale on heating elements, inside pipes, and across surfaces.
The energy cost is measurable too. Scale on a boiler heat exchanger acts as insulation, making the system burn more gas or electricity to reach the desired temperature. Research from British Water suggests even 1.5mm of scale can increase heating costs by 12%.
Systems We Install in the SO20 Area
We fit water softeners from Kinetico, Harvey, Infinity, and TwinTec across the SO20 postcode. For a small town like Stockbridge, where many homes are period properties with character features and limited cupboard space, choosing the right unit matters. We won’t recommend a system that’s too big for your home or too small for your household.
Our free home survey covers water testing, pressure checks, space assessment, and a clear written quote. There are no hidden extras.

What Our Customers Say
“We've had fantastic service from Southern Softflow from initial enquiry through to installation and beyond. This is our first water softener (TwinTec S5) and we can't fault it (we wish we'd installed one years ago). Southern Softflow's friendly and accommodating service is what set them apart from other companies that quoted. There was no pressure to place an order, and they were very accommodating, as this softener was purchased during a renovation of the whole downstairs, including new kitchen, bathroom & plumbing throughout, so they had to coordinate with our plumber and fit in around other trades. Competitively priced. Fantastic product. Excellent service. I highly recommend Southern Softflow.”
“Fast response to our enquiry, full information provided, work booked for following week. Fitter arrived on time, pleasant, efficient, very tidy and cleaned up when work finished. Very neat pipework, showed us how to isolate soft water if required at any time, and showed us position of new stopcock. Explained how filter system worked, helped us to set up App for notifications when salt low. Stacked spare salt in garage, advised how to apply for more supplies. Presented us with a delightful gift hamper of locally sourced products. Would highly recommend Southern Softflow Ltd.”
“I have dealt with Southern Softflow for 22 years. Recently after 22 years a fault developed on the machine. The machine was taken away and repaired at a very reasonable cost. As I had moved house I had the machine installed by the kitchen company installing the kitchen and they made a poor job of the pipework needed. When Will from Southern Softflow brought the repaired machine back he rerouted the pipework and put new valves in and did a very neat and professional job. I am delighted. A very genuine and professional company ,a delight to deal with.”
“The service from start to finish was exceptional. Very skilled and knowledgeable plumbers, nothing was too much bother, brilliant receptionist, everything fitted well and explained along the way, went above and beyond - even reinstalled and adapted the cupboard around the new water softener and left us a box full of gifts and goodies! A pleasure to deal with such a great team, we highly recommend them.”
“Brilliant service. Survey done clear explanation of product from Ben. Fitting done three days later. Very helpful and tidy technician. Added a hard water tap at the last minute no problem. Would highly recommend the service and product. Thanks guys!”
“Moving home to an area with very hard water, I decided it was time to install a water softener. After research, I chose Southern Softflow, who offered exactly the reassurance and expertise I was seeking. Decision to installation took two days. Installation itself took a little over two hours, was carried out neatly, efficiently, and professionally. The new tri-flow drinking tap looks great in the kitchen, and even though I’ve used Brita filters for years, tea already tastes noticeably better after only 12 hours. Many thanks to Ben, Will, and the team, greatly appreciated. A full 10 out of 10.”
