Forms and certificates
For water users who have not yet installed a meter
Water users who install a new or replacement meter need to:
- ensure the meter is pattern approved (except for open channel works). Water users wishing to install an open channel meter must have the design certified by a duly qualified person
- have the meter installed and validated by a duly qualified person, and fitted with a data logger, tamper-evident seals, and (if required) connected, via telemetry, to the government’s data acquisition service, and
- submit the completed validation certificate (below). Water users with an open channel meter also need to submit the completed design certificate (below).
Name | What is it used for? | Who fills it out? | Who submits it and when? |
---|---|---|---|
Validation certificate | To demonstrate the meter has been validated |
A duly qualified person
Note: the duly qualified person must give the certificate to the water user within 7 days of carrying out the validation |
Water users within 28 days of receiving the certificate
Note: validation by a duly qualified person must be done every 5 years (or every 12 months for open channels), and whenever maintenance affects the metrology of the meter. A new validation certificate needs to be submitted each time this occurs |
Design certificate for open channel metering equipment | To demonstrate the design of an open channel meter is compliant |
A duly qualified person
Note: the duly qualified person must give the certificate to the water user within 7 days of carrying out the design certification | Water users — within 28 days of receiving the certificate |
For water users who already have a pattern approved meter installed before 1 April 2019
This section applies to pattern approved meters installed before 1 April 2019. See below for non-pattern approved meters.
Water users who wish to keep an existing pattern approved meter need to:
- have the meter validated by a duly qualified person, and fitted with a data logger, tamper-evident seals, and (if required) connected, via telemetry, to the government's data acquisition service, and
- submit the completed report (below) and validation certificate (below).
Name | What is it used for? | Who fills it out? | Who submits it and when? |

Report to rely on transitional arrangements to keep existing metering equipment |
For water users who want to keep meters that were installed before 1 April 2019
The report must include supporting documentation — such as a certificate of accuracy — to demonstrate that the meter is compliant | Water users | Water users —upload before roll-out date |
Validation certificate | To demonstrate the meter has been validated |
A duly qualified person

For water users who already have a non-pattern approved meter installed before 1 April 2019
This section applies to non-pattern approved meters installed before 1 April 2019. See above for pattern approved meters.
Water users who wish to keep an existing non-pattern approved meter need to:
- have the meter fitted with a data logger, tamper-evident seals, and (if required) connected, via telemetry, to the government's data acquisition service, and
- submit the completed report (below) plus either:
- completed validation certificate (below) and a manufacturer’s certificate of accuracy, or
- completed certificate (below) from a duly qualified person confirming the meter is accurate to within +/-5%.
We are also developing a guidance note to help water users and duly qualified persons understand what needs to be done to keep a non-pattern approved meter.
