Access the Water Technology Product List (WTL)

Before you start

The Water Technology List (WTL) provides details of which products you can claim enhanced capital allowances (ECA) for as part of the ECA water scheme. A product must be on the WTL when you buy it for you to claim an ECA through your income tax Self Assessment or your corporation tax Self Assessment return.

You can use the WTL to search for products by technology or by manufacturer/supplier.

For general enquiries relating to the WTL, you can call the WTL Advice Line on Tel 0844 875 5885. Alternatively, you can email your questions to wtl@aeat.co.uk.
