IMPORTANT NEWS – OUR CHARGES CHANGED FROM 1 APRIL 2018
The Water Act 2014 brought in changes that mean that all water companies have been required to modify the way they charge customers for Developer Services related activities from April 2018.
Ofwat, the economic regulator, has published new rules that now mean that water companies will provide more fixed charges rather than bespoke prices on request. Ofwat’s rules follow the overarching principles of:
- Stability and predictability
- Transparency and customer-focused charging
- Fairness and affordability, and
- Environmental protection.
From 2017/18 the way that we charge for Developer Services related activities has changed and if you would like to know more further details can be found on the following links:
