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
“From the first contact through to survey visit and arranging for installation, this family-run company was excellent, with plenty of communication. The water softener had to be installed in a very restricted space with very difficult to access mains water inlet and drain. However the company plumber found a workaround, even preserving some of the middle shelf in the cupboard concerned. The installation was completed in one morning, working was clean, and the finished job is very neat.”
“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.”
“We recently had Southern Softwater visit our home to walk us through the available options, and the experience from start to finish was excellent.The initial consultation was clear, informative, and pressure-free. They took the time to understand our needs, explained the different systems in a straightforward way, and answered all of our questions patiently. It felt like they genuinely wanted to help us make the right decision rather than just make a sale.The installation process was just as impressive. The installer arrived on time, was extremely professional, and worked efficiently while keeping everything tidy. He explained how the system works, made sure everything was set up perfectly, and left the area clean once the job was complete.Overall, we’re delighted with both the service and the product. It’s rare to find a company that delivers such a smooth and professional experience from consultation through to installation. Highly recommended.”
“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!”
“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.”
“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.”
