Estimates for a small start in the UK, not guarantees.

What it is

You buy water softeners, filters, UV units and consumables such as salt and filter cartridges from manufacturers or wholesalers, then sell them locally. You visit customers to advise, quote and arrange installation, either yourself or through a plumber you work with.

Your first three steps

  1. Contact two or three UK manufacturers or wholesalers about trade accounts and reseller terms
  2. Choose a small range of products for your area, such as domestic softeners and farm water filters, and check any manufacturer training
  3. Offer free water hardness tests to neighbours, farms and local businesses to start building quotes and repeat customers
Who pays

Homeowners in hard water areas, farms and smallholdings, small food and hospitality businesses, and landlords.

How it makes money

Margin on equipment sales and installation, plus repeat orders for salt, cartridges and chemicals, and servicing visits.
