If you are a business customer and wish to make a complaint about your water supplier, you must first go through the company’s formal complaints procedure.
If you are unhappy with the outcome of your water supplier’s complaints process, and you have a final decision letter from them, then you may have your complaint reviewed by the Scottish Public Services Ombudsman (SPSO). The SPSO is the final stage for complaints about public services in Scotland and their service is independent, free and confidential.
Freepost SPSO (this is all you need to write on the envelope, and you don't need to use a stamp)
