About Us

The Association of Independent Water Softener Experts (AIWSE) is a not-for-profit, member-led organisation committed to raising standards within the UK's water softening and treatment industry.

Who We Are

AIWSE brings together independent water treatment specialists from across the UK—many of whom have operated as competitors for years—under one shared vision: to provide consumers with high-quality, ethical, and expert-led advice and service in water softening and filtration.

Our members are family-run businesses with strong regional roots, offering professional installations, aftercare, and support for both domestic and commercial clients. All members are vetted, insured, and committed to continuous development and best practice.
