Privacy Policy

Alt HAN Co is a vehicle established to allow all Great Britain (GB) energy suppliers to deliver Alternative Home Area Network (Alt HAN) technological solutions and services. Our work includes assessing for the deployment of smart metering devices and technological solutions to allow smart meters to communicate with each other, otherwise known as Alt HAN equipment. Alt HAN Co is committed to protecting your privacy and compliance with all relevant legislation, including the UK Data Protection Act 2018 (DPA), in addition to the Privacy and Electronic Communications Regulations 2003 and other applicable legislation.

This Privacy Policy covers our treatment of information that is gathered by this website and while the deployment and provision of Alt HAN services, including by our third-party partners and contractors. This Policy does not apply to information collected by third party websites, or personal data collected in the context of employment. Additionally, certain information may be collected by energy suppliers, which may be used during the Alt HAN services. In this case, we take steps to ensure such organisation provide notice to these individuals that their personal data will be processed for Alt HAN services, where they are best placed to do so.

Typically, we will collect the personal data of energy customers, and residents and landlords in premises that may be suitable to benefit from Alt HAN services, in addition to staff at our suppliers, contractors, partners and other third parties. This will include the following:

Contact & Business Details.
You may give us your Contact Details by filling in forms on our website, through an existing business relationship with your company, or through the course of research or surveys conducted in the deployment of Alt HAN services. We may use this information to contact you or during the provision of services to you. This information could also be collected through your interaction with Alt HAN Co during business, including where you provide services to Alt HAN, as is related to the installation of Alt HAN smart metering equipment in your building, or when you submit a complaint to us or make any other request.

This will include information such as:

  • Your name
  • Position and Company
  • Phone number
  • Physical address
  • Email address
  • Contact preferences (for marketing purposes)
  • Country or location

Financial Details.
Where we need to make a payment to you or your organisation, or issue an invoice, we many collect your financial details to facilitate this. Generally, this will include:

  • Bank name and sort code
  • Bank account number

Energy Data.
Where you are a resident at a building that may be suitable for the deployment of Alt HAN equipment, or otherwise fall within the remit of smart metering as an energy customer, we may process personal data specific to your smart meter, including meter serial numbers (MPANs, MPRNs, MPxNs). We may receive such data from external energy databases such as those provided by ECOES (RECCo), Xoserve and Electralink, as well as directly from your energy supplier. We may also process limited meter reads and consumption data for short durations, as incidentally collected by Alt HAN Co or your energy supplier during the testing of smart metering equipment. We process such data in line with the Smart Energy Code (SEC), which provides the basis for our business processes and use of this data.

Building Data.
Where you are a resident, tenant, owner or other occupant at a building that may be suitable for the deployment of Alt HAN equipment, or otherwise fall within the remit of smart metering as an energy customer, we may also collect and store information about your premise, including its address and postcode, from external energy databases. We use this information to conduct a market sizing analysis of the suitability of business premises for Alt HAN smart metering equipment. This will generally not be considered personal information, and will largely consist of location (e.g., GPS coordinates), building measurements and specifications.

Technical Data.
Similarly, to other websites, we may also collect information from your device and store it in log files, as you interact with our website or websites hosted by our third-party partners or cookies embedded in our website, in order to support your website experience and interactions with us. This information could include data on your IP Address, Location, device identifiers and information on links that you click on or content that you view.


Other Information.
We may also collect information relating to an activity/complaint or engagement with the member of the public. We may also collect information in relation to Health and Safety incidents that occur with respect to our sub-contractors/surveyors when conducting surveys on-site, as part of our Health and Safety duty of care. This information will be anonymised where possible.We may also process photographs/video/audio recordings of energy supplier’s employees and other attendees, as collected at Accelerated Solutions Environment (ASE) events as part of the course of our business activities. Moreover, our surveyors (sub-contractors) may also take photographs of residences in the course of surveying them for market sizing activities, which may incidentally include photographs of residents (although we take steps to check and remove photos that include images of residents).

We will only use your personal data when the law allows us to. Most commonly, we will use your personal data in the following circumstances:

This applies where you have given us consent to the processing. We do not generally collect personal data with consent, except when you have given us consent to send marketing information to you. Where you have given consent, you have the right to withdraw consent to marketing at any time by contacting us.

Legitimate Interests:
We may rely on our legitimate interests (or those of a third party) – including conducting market sizing activities and administrative support to ensure GB’s smart metering rollout, as well as maintaining communications with our business partners or defending against any potential legal claims. This will apply in the context of the deployment and testing of Alt HAN equipment, maintaining information on complaints from residents and members of the public and engaging in certain communications about Alt HAN services, where your interests and fundamental rights do not override those interests.

Performance of a contract:
We may also process your data for the performance of a contract we have with you or your organisation (e.g., an Alt HAN Co subcontractor). This will include, for example, processing information of our subcontractors’ staff, and processing data of suppliers and other parties in relation to the installation of Alt HAN Equipment.

We may also store your personal data where we need to comply with a legal obligation. This will also include processing data for Health and Safety assessments under our Health and Safety duty of care, Health and Safety Act 1974 and RIDDOR, and where we are obliged to retain payments records pursuant to financial obligations.

To determine the appropriate retention period for personal data, we consider the amount, nature and sensitivity of the personal data, the potential risk of harm from unauthorised use or disclosure of your personal data, the purposes for which we process your personal data and whether we can achieve those purposes through other means.

The Alt HAN Inventory is a database we have developed with building and premise data, which we use to assess residences for their suitability for the deployment of Alt HAN equipment. This may also include information about residents, including Energy Data. We have several security safeguards in place around the Alt HAN Inventory, which involve i) VPN connections for remove logins, or permitting connections from certain buildings or addresses (such as our office), or ii) log-on credentials and 2 factor-authentication in a web-based version of the Inventory interface.

Third Parties:
We may also transfer your personal data to our clients and third parties, as detailed below. Some of these third-party providers may have staff outside the UK or European Economic Area (EEA), and may access personal data, subject to suitable and secure safeguards. Where these are used, we typically ensure that such systems employ appropriate access controls to limit usage only to the necessary staff. These are discussed further in the section below.

We may share your personal data with the parties set out below. This will typically include in the following circumstances:

  • Contractors and partners that we work with to carry out Alt HAN Co business processes (including the identification of residences for Alt HAN equipment), such as Capgemini, who act as an Operational Service Provider, and sub-contractors, such as Daly International

Where we use such third-party providers as listed in Section 6, we take steps to enter into agreements to ensure that such third parties have the adequate safeguards in place, which include:

Generally, where data has been transferred from Alt HAN Co to other third parties outside the UK, we will ensure that any parties who receive such data have the appropriate measures to ensure secure transfers in place. In particular, this will include our sub-contractors and business partners, whose staff may access personal data on the Alt HAN Inventory from outside the UK and may include some of our systems used for storing and sharing personal data.

Alt HAN Co will not transfer any data or allow any access to such data to such third parties until one of the following mechanisms are in place:

  • An adequacy decision from the Secretary of State or Information Commissioner’s Office (ICO)
  • UK-approved Standard Contractual Clauses or International Data Transfer Agreements
  • Binding Corporate Rules that have been put into place.

Additionally, where data transfers occur to countries outside of the UK, European Economic Area, or those without adequacy decisions, Alt HAN Co will assess the laws and practices of the third country of destination for the transfer and of any relevant contractual, technical or organisational safeguards put in place, before allowing the transfer to occur.

Under certain circumstances, you have rights under the GDPR and DPA in relation to your personal data, upon request:

  • Request access to your personal data (commonly known as a “data subject access request”). This enables you to receive a copy of the personal data we hold about you and to check that we are lawfully processing it.
  • Request correction of the personal data that we hold about you. This enables you to have any incomplete or inaccurate data we hold about you corrected, though we may need to verify the accuracy of the new data you provide to us.
  • Request erasure of your personal data. This enables you to ask us to delete or remove personal data where there is no good reason for us continuing to process it. You also have the right to ask us to delete or remove your personal data where you have successfully exercised your right to object to processing, where we may have processed your information unlawfully.
  • Request the transfer of your personal data to you or to a third party. We will provide to you, or a third party you have chosen, your personal data in a structured, commonly used, machine-readable format. This right only applies to automated information which you initially provided consent for us to use or where we used the information to perform a contract with you.
  • Object to processing of your personal data where you feel it impacts on your fundamental rights and freedoms, by contacting us to inform us of this.
  • Opt-out from marketing communications or newsletters we may send to you. You should request this by contacting us at or replying to the marketing email you received with [OPT OUT].

To exercise these rights with respect to Energy Data, please contact your energy supplier in the first instance.

You will not have to pay a fee to access your personal data (or to exercise any of the other rights). However, we may charge a reasonable fee if your request is clearly unfounded, repetitive or excessive. Alternatively, we could refuse to comply with your request in these circumstances. We may need to request specific information from you to help us confirm your identity and ensure your right to access your personal data (or to exercise any of your other rights). This is a security measure to ensure that personal data is not disclosed to any person who has no right to receive it. We may also contact you to ask you for further information in relation to your request to speed up our response.

We try to respond to all legitimate requests within one month. Occasionally it could take us longer than a month if your request is particularly complex or you have made several requests. In this case, we will notify you and keep you updated.
