You can be charged for building water on a contract value or metered basis. However, if work has already started on site, payment must be based on contract value.

If the existing supply is already metered, we must be notified before work commences.

Where an existing unmetered supply is used for building work or alterations to existing properties with a contract value of over £100,000 the charge is 0.17% of contract value, + VAT.

We may require evidence of contract value.

Where the contract value is less than £100,000, the property will remain on the current domestic rate of charge.
