The Energy Company Obligation (ECO) scheme involves major energy suppliers offering financial support for implementing energy efficiency measures in residential properties. To proceed with installing a measure in your home under the ECO scheme, we require certain personal information from you, which will be shared with other organizations. Rest assured, we will only gather and utilize personal data as outlined here, ensuring compliance with legal obligations and respect for your rights.

The personal information we gather and utilize includes:

  • Your name, address, and, in certain cases, your date of birth (to verify your eligibility for the scheme and to communicate with you regarding your installation).
  • Verification of identity (collected for evidential purposes or to confirm eligibility).
  • Documentation demonstrating proof of benefits and income issued by the Department for Work and Pensions and HMRC (limited to confirming eligibility for the scheme).
  • Your phone number and email address (for necessary communication related to the purpose stated in this notice).
  • Optional: Details of your financial contribution toward the installation cost (to aid the Department for Business, Energy and Industrial Strategy in devising future schemes).


Providing Your Personal Data

We will clearly indicate if the provision of certain personal data is optional. However, in all other instances, it is imperative to provide your personal data; failure to do so will result in the inability to install a measure in your home under the ECO scheme.

Using Your Personal Data (Legal Basis and Purpose)

We will process your personal data in the following ways:

  • As required to fulfill our contractual obligations with you, such as managing and executing the contract (including installing a measure in your property).
  • As necessary to pursue our legitimate interests, including verifying your eligibility for the ECO scheme, sharing your data with third parties involved in administering, supporting, or enforcing the ECO scheme (as outlined under ‘Sharing Your Personal Data’), and collecting any financial contributions you’ve made toward the installation cost.
  • As necessary to comply with legal obligations, for instance, in cases where you exercise your rights to make requests under data protection laws.


There may be instances where we need to process special categories of data, such as information regarding your health to verify your eligibility for the scheme. In such cases, we will furnish you with separate information detailing how we will process your data and the legal basis for doing so.

Your data will be processed solely for ECO-related purposes unless you provide specific consent otherwise.

Criteria for Data Retention Periods:

  • For measures with a twenty-five year guarantee, such as wall insulation, your personal data may be retained for up to twenty-five years or as long as needed to match the guarantees’ lifetime.
