If it is not possible to fit a meter at your business premises, we will assess how much water you are likely to use to set your charges.

These charges will be based on the type of business carried out at the premises, your standard industrial classification for VAT and the number of people working there.

If it is not possible to fit a meter at your premises, we will let you know and you will need to print and complete the following forms:

• Assessed charges review form (0.14Mb)
• VAT on commercial water service charges including form (0.09Mb)

Please send your completed forms to us at:

Thames Water
PO Box 508
Swindon
SN38 1TA

It's very important that you tell us this information so we can set up your account properly and so that you don't pay higher charges than you should do.
