Who we are

This privacy notice explains how GreenTech Ltd ("GreenTech", "we", "us") collects and processes personal data in connection with this website and our commercial pest management services. GreenTech Ltd is a company registered in England & Wales, with its registered office in London. We are a Montclair Capital operating company.

For UK GDPR purposes, GreenTech is the controller of personal data collected through this website. For data we process on a client's behalf as part of GreenTech OS — for example, employee records related to site access — we may act as a processor under a data processing agreement, with the client as controller.

What personal data we collect

We collect personal data only where it is necessary for a specific purpose:

  • Enquiry data — name, role, company, email, phone number, sector, estate scale, and the content of your enquiry, when you complete the contact form or write to us.
  • Subscription data — email address, when you subscribe to GreenTech Insights.
  • Account data — name, work email, role, and authentication metadata, where you have a GreenTech OS user account under a client contract.
  • Technical data — IP address, browser, device type, referrer, pages visited, and cookie identifiers, collected via the website and any analytics tools we use.
  • Operational data — site access logs and treatment-record metadata generated by GreenTech OS, where attributable to an individual technician or operator.

We do not knowingly collect data from children under 16. The site and the platform are intended for institutional B2B use.

Why we use it

We use personal data to:

  • Respond to enquiries and provide information about GreenTech services.
  • Deliver the GreenTech OS platform and the contracted pest management service.
  • Send GreenTech Insights to subscribers (you can unsubscribe at any time).
  • Operate, secure, and improve the website and platform.
  • Meet legal, regulatory, accounting, and reporting obligations.

We do not use personal data for automated decision-making with significant effect on you.

Our lawful basis

We rely on the following lawful bases under UK GDPR:

  • Legitimate interests for responding to B2B enquiries, providing service-related communications, and operating and securing the website. We balance these interests against your rights and freedoms.
  • Contract for delivering the GreenTech OS service to clients and authorised users.
  • Consent for the GreenTech Insights subscription and for non-essential cookies.
  • Legal obligation for compliance, tax, and statutory reporting.

Sharing and processors

We do not sell personal data. We share it with carefully selected sub-processors who help us run the service. Current sub-processors include AWS (UK-region hosting), ThingsBoard PE (platform layer), Make.com (workflow integration), Google Workspace (productivity and email), GoCardless (payment), DocuSign (contract execution), and an email-delivery provider for transactional and subscription emails.

Each sub-processor operates under a written data processing agreement with appropriate technical and organisational measures. The current list is published in our security pack and updated within 14 days of any change. You can request the current list at any time.

We may disclose personal data when required by law, by a court order, by a properly constituted regulatory authority, or where necessary to protect our rights or the rights of others.

Retention

We keep personal data only for as long as it is needed for the purpose it was collected for, or for as long as we are required to retain it by law.

  • Enquiry data — up to 24 months from last contact.
  • Subscription data — until you unsubscribe, plus 12 months.
  • Account data — for the duration of the client contract, plus 6 years for accounting and statute-of-limitations purposes.
  • Treatment-record data — held in the audit chain for the contract duration, exported to the client on termination, and deleted thereafter except for any data we are required to retain.
  • Website analytics — up to 26 months.

Your rights

You have rights under UK GDPR, including the right to:

  • Access the personal data we hold about you.
  • Rectify inaccurate or incomplete data.
  • Request erasure ("the right to be forgotten") in certain circumstances.
  • Restrict or object to processing.
  • Port your data in a structured, commonly used, machine-readable format.
  • Withdraw consent at any time, where consent is the lawful basis.

To exercise any of these rights, write to privacy@greentech.co.uk. We will respond within one calendar month.

You also have the right to complain to the Information Commissioner's Office (ICO). The ICO's address is Wycliffe House, Water Lane, Wilmslow, Cheshire, SK9 5AF. ico.org.uk
