Sustainable Drainage Systems Limited (SDS Limited) has a responsibility to document how we will protect your personal data. This is a legal requirement of the UK GDPR under the ‘right to be informed’.

This privacy notice will outline our responsibilities to you.

This privacy notice was last updated in August 2022.

1.0 Key Terms

1.1 Whilst every effort has been made to outline our responsibilities to you in as clear, concise, and easy-to-understand manner as possible, we do need to use certain terms throughout this privacy notice.

1.2 We will now provide an easy-to-understand definition of each term:

  • Data Controller: A data controller is responsible for deciding how your personal data is processed and protecting it from harm.
  • Data Processor: In a similar way to data controllers, data processors must protect people’s personal data – but they only process it in the first place on behalf of the controller. They would not have any reason to have the data if we the data controller had not asked them to do something with it.
  • Data Protection Act (DPA 2018): The DPA 2018 sets out the data protection framework in the UK, alongside the UK GDPR. It contains three separate data protection regimes:
    • Part 2: sets out a general processing regime (the UK GDPR);
    • Part 3: sets out a separate regime for law enforcement authorities; and
    • Part 4: sets out a separate regime for the three intelligence services.
  • Data Subject: A data subject is someone who can be identified from personal data. The data could be their name, address, telephone number, or something else – but if it is about a person, then they are the data subject. They are the ‘subject’ of the data.
  • GDPR: This stands for General Data Protection Regulation (GDPR), the EU’s agreed standards for data protection that are also written into UK law through the Data Protection Act 2018 (DPA 2018). The transition period for leaving the EU ended on 31 December 2020. The GDPR has been retained in UK law as the UK GDPR and will continue to be read alongside the DPA 2018, with technical amendments to ensure it can function in UK law.
  • Individual Rights: In data protection law, data subjects have rights over their personal data. These generally allow the data subject to ask the data controller to do something or stop doing something, with their personal data. There are eight individual rights. SDS Limited, when handling people’s personal data, will comply with these rights whenever they are used, unless it is an exceptional situation.
  • Information Commissioner’s Office (ICO): The Information Commissioner’s Office (ICO) is the UK’s independent body set up to uphold information rights, covering laws including the Data Protection Act (2018), Freedom of Information, Privacy and Electronic Communications Regulations (PECR) and UK GDPR.
  • Lawful Basis: A lawful basis is the reason or legal ground SDS Limited relies on regards the lawful processing of a data subject’s personal data. There are six lawful bases: consent, contract, legal obligation, vital interests, public task, and legitimate interests. There is no single lawful basis that is better or more lawful than any of the others.
  • Personal Data: Personal data is information about who you are, where you live, what you do, and more. It is all information that identifies you as a data subject.
  • Privacy and Electronic Communications Regulations (PECR): PECR sits alongside the DPA 2018 and the UK GDPR. They give people specific privacy rights in relation to electronic communications. There are specific rules on:
    • marketing calls, emails, texts, and faxes;
    • cookies (and similar technologies);
    • keeping communication services secure; and
    • customer privacy as regards traffic and location data, itemised billing, line identification, and directory listings.
  • Processing: Processing means taking any action with a data subject’s personal data. This begins when a data controller starts making a record of information about the data subject and continues until SDS Limited no longer needs the information for the original lawful purpose.

2.0 Scope

2.1 The scope for SDS Limited is any data subject, whose personal data is processed, in line with the requirements of the DPA 2018, PECR, and UK GDPR. From time to time, we may also need to meet the requirements of additional UK privacy legislation and overseas privacy legislation, such as the EU GDPR.

2.2 We also acknowledge any additional responsibilities requested by the industry regulator in the UK, the Information Commissioner’s Office (ICO).

2.3 The DPA 2018 and UK GDPR have a material scope covering personal data that is processed either electronically or is processed as a part of a physical filing system. For example, any personal data that may be uploaded to a computer/electronic device or stored in a structured paper filing system.

2.4 SDS Limited will adhere to the seven UK GDPR data processing principles when handling personal data:

  • Lawfulness, fairness, and transparency
  • Purpose limitation
  • Data minimisation
  • Accuracy
  • Storage limitation
  • Integrity and confidentiality (security)

2.5 All associates and employees of SDS Limited who interact with data subjects are responsible for ensuring that this privacy notice is drawn to the data subject’s attention, at the earliest available opportunity.

If the international data transfer is outside the EU/EEA/UK then appropriate safeguards or derogations would be put in place, such as Data Protection Impact Assessments (DPIAs). This privacy notice would also be updated.

  • Fraud prevention agencies, money laundering agencies, and associations.

6.6 SDS Limited will share personal information with law enforcement or other authorities if required by law.

7.0 Data Minimisation

7.1 SDS Limited always ensures the personal data we are processing is:

  • Adequate – sufficient to properly fulfil our stated purpose;
  • Relevant – has a rational link to that purpose; and
  • Limited to what is necessary – we do not hold more than we need for that purpose.

The UK GDPR does not define these terms. As this is the case, SDS Limited accepts these terms may have a differing definition from one individual to the other, as the processing will depend on the specified purpose for collecting and using the personal data.

7.2 In order to assess whether we are holding the right amount of personal data, we demonstrate clearly why we need it, before engaging with the data subject.

7.3 For special category data or criminal offence data, we understand the importance of collecting and retaining only the minimum amount of information.

7.4 SDS Limited undertakes an annual data protection audit with an external certified data protection service provider, to review our processing to check that the personal data we hold is still relevant and adequate for the stated purposes, and we delete anything we no longer need.

8.0 Accuracy

8.1 SDS Limited will take all reasonable steps to ensure the personal data we hold is accurate and up to date.

8.2 SDS Limited will take reasonable steps to ensure that the personal data we hold is not incorrect. This may involve contacting you via our official communication channels, to ensure all personal data held is accurate.

8.3 SDS Limited will always record the source of where personal data came from and ensure that source is compliant with UK privacy laws, including the UK GDPR.

8.4 If we need to keep a record of a mistake, we clearly identify it as a mistake, and add this to our records of processing for audit purposes, and continuous improvement.

8.5 All SDS Limited records clearly identify any matters of opinion, and where appropriate whose opinion it is and any relevant changes to the underlying facts.

8.6 SDS Limited will comply with the individual’s right to rectification, and carefully consider any challenges to the accuracy of the personal data.

8.7 As a matter of good practice, we keep a note of any challenges to the accuracy of personal data.

9.0 Storage Limitation

9.1 SDS Limited will not keep personal data for longer than we need it.

9.2 SDS Limited will only keep personal data for the period outlined to meet the requirements of the contract, legal obligation, or legitimate interest identified. We always document our purposes for holding personal data.

9.3 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, and the applicable legal requirements.

9.4 Furthermore any retention of personal data will be carried out in compliance with legal, professional body, and regulatory obligations. These data retention periods are subject to change, due to any revisions of associated legislation, regulations, or requirements.

9.5 SDS Limited acknowledges that UK privacy legislation does not determine how long personal data needs to be kept. This is up to us as data controllers or processors to determine and document accordingly at the earliest possible opportunity. For example, in contracts or proposal documentation.

9.6 SDS Limited has a personal data retention policy and procedure in place, which documents the types of records or information we hold, what we use it for, and how long we intend to keep it.

9.7 SDS Limited periodically reviews the personal data we hold, and erases or anonymises it, when we no longer need to process it.

9.8 SDS Limited also considers any challenges to the retention of personal data. We understand that individuals have a right to erasure if we no longer need the personal data.

9.9 SDS Limited acknowledges there are exceptions to retention periods. Here we can keep personal data for longer if we are only keeping it for public interest archiving, scientific or historical research, or statistical purposes. We would always inform you if this was the case, along with our lawful basis for retention.

9.10 Any personal data held as physical documents are securely stored pre-destruction, and securely destroyed, with a Certificate of Destruction issued in line with our UK GDPR and our data retention policy.

10.0 Integrity and Confidentiality (Security)

10.1 SDS Limited undertakes an analysis of the risks presented by our processing and uses this to assess the appropriate level of security we need to put in place. We review our Business Continuity Plan (BCP) annually.

10.2 We have an information security policy and take steps to make sure the policy is implemented. For example, we undertake an annual information security review with an accredited external provider. We make sure that we regularly review our information security policies and measures and, where necessary, improve them.

10.3 SDS Limited believes in building an information governance framework by design. Where necessary, we have additional policies and ensure that controls are in place to enforce them.

10.4 SDS Limited has put in place basic technical controls such as those specified by established frameworks like Cyber Essentials.

10.6 SDS Limited understands the requirements of confidentiality, integrity, and availability for the personal data we process.

10.7 SDS Limited makes sure that we can restore access to personal data in the event of any incidents, such as by establishing an appropriate backup process.

10.9 Where appropriate, we implement measures that adhere to an approved code of conduct or certification mechanism (e.g., Cyber Essentials, ISO:27001).

10.10 We ensure that any data processor we use also implements appropriate technical and organisational measures.

10.11 SDS Limited does not use tracking cookies on our website to track user behavior and/or improve site experience. The UK GDPR and PECR interpret data collected by cookies as personal. It prohibits the collection of personal data without consent, which means a website is only allowed to collect information that the user voluntarily inputs. This includes name, email address, phone number, or any other information that the user shares with the website. The cookie consent must be freely given, specific, informed, and unambiguous. SDS Limited does not use these tracking cookies, giving the user complete control over their personal data.
