Only non-household customers with business premises can choose their water supplier.
Use our step by step eligibility checker to see if you qualify.
The Open Water eligibility checker is an indicative tool to help customers assess their potential eligibility for switching water retailer.
Your water company is responsible for ensuring that eligibility is assessed correctly, however for more detailed information about eligibility please see Ofwat’s full eligibility guidance and supplementary guidance.
The Open Water eligibility checker is therefore not the final determination of eligibility and companies may change/assess eligibility as required under their obligations. Ofwat reserves the right to make determinations where appropriate.
