Consumption data

To help customers understand their water usage we offer a range of consumption data services.

Data protection

With all the services we provide that are outlined below, you’ll need to comply with all relevant data protection legislation and codes of practice. Any data we supply is in full compliance with data protection laws and you'll need authorisation from the customer to collect data.

If you’re aware of any breach of relevant data protection legislation and codes of practice you must tell us immediately.

Providing smart meter reads

To help retailers accurately bill customers, we can provide retailers with meter reads from our digital meters in AMI mode.

You can choose from following three options

  1. a read requested on an ad-hoc basis
  2. a read provided every month
  3. a read provided every 6 months

If you'd like to submit a request for a large number of meters, please email wholesalemarketservices@thameswater.co.uk so we can discuss your requirements as we may be able to handle such requests in bulk rather than as individual requests.

Accessing digital meter data

We install digital meters for all new or replacement meter requests. If meters are located within London and in our wide area network we’re able to provide a digital meter data service. When we receive your service request form, we’ll check the location of the meter. We'll then let you know if we can provide digital data for it.

If we’re unable to provide a smart digital data service you can gather data from the digital meter by using automatic meter read (AMR) mode.

Water services intermediaries need to include evidence of customer authorisation when submitting a service request form. Please send your request to wholesalemarketservices@thameswater.co.uk.

Providing consumption data from our loggers

We can provide data from our loggers on a monthly basis or historical data for a particular time period.

Installing your own data logger

You can attach your own consumption monitoring equipment (logger) to one of our meters but you’ll need to make sure that it doesn’t affect our existing equipment in any way. If you’re uncertain, please contact us.

If you’re unable to fit your own logging equipment, we may be able to provide you with a consumption data service or, you can ask us to exchange the meter so that it can be logged. Alternatively, you may install a private sub-meter downstream of the meter.

Water service intermediaries can ask us to exchange the meter by sending their completed service request form to our Wholesale Service Desk. You’ll need to include evidence of customer authorisation when submitting a service request form.

When you have fitted a logger, please let us know so that we can update the Central Market Operating System. Please email the supply point ID, meter manufacturer, meter serial number and date of connection to wholesalemarketservices@thameswater.co.uk.

Fitting splitters for data loggers

If you’re fitting a data logger to our meter and it needs a splitter, you can ask us to install the splitter equipment for you. Depending on what’s involved, we’ll either visit your customer to fit the splitter or arrange a site survey to check what’s needed. When the splitter has been fitted, we’ll let you know that the work has been completed.
