Charges and performance

Charging arrangements

From 1 April 2018, our new connection charges have been set according to the new rules published by our economic regulator, Ofwat.

We have:

  • Set up-front fixed prices, published in our charging arrangements document.
  • Set infrastructure charges based on the incurred cost of network reinforcement rather than a notional maximum value.
  • Provided income offset between developers and other customers.

The services and charges affected include new water and wastewater connections, new water mains and sewers, infrastructure charges and income offsetting.

For further information please refer to our charging arrangements via the link below. We have also created a new calculator, which will allow you to interactively generate an initial quotation for your project.

The new calculator is available below, for any queries please contact

Our performance

Water UK has produced a set of standards which measure our performance in relation to a number of Developer Services activities.

All water and sewerage companies will be monitoring their performance, starting 1 April 2015, with the results published on a quarterly basis.

We are publishing these standards to provide information about our performance in dealing with new development proposals and implement procedures, where necessary, to improve our levels of service.

Results are published every quarter. Further details of the reporting standards can be found on the Water UK website.

For water supply, our performance for the second quarter saw a significant improvement which put us above the industry average.

However, for sewerage we saw a slight drop in performance which sees us below the industry average again for the second quarter.

We recognise that this is not where we want to be and measures are being taken to improve our performance for the third quarter.
