Privacy Policy
Last updated: October 2026
This policy explains how Delta Flow collects, uses and protects the personal information you give us. We are the data controller for that information.
Who we are
Delta Flow, 2 North View, Rothwell, Leeds, West Yorkshire LS26 0BQ. You can reach us by email at hello@delta-flow.co.uk or by phone on 0113 850 0510.
What we collect
We only collect what we need in order to quote for and carry out work:
- Your name, email address, phone number and the address of the property concerned.
- Details of the work you are enquiring about, including anything you tell us in a message.
- Records of the work we have carried out, including certificates, warranty registrations and invoices.
- Basic technical information collected automatically when you use this website, such as your IP address, browser type and the pages you visit.
How we use it
- To respond to your enquiry and prepare a quotation.
- To carry out the work, order materials and arrange access.
- To issue certificates, invoices and receipts, and to register manufacturer warranties on equipment we install.
- To meet our legal and regulatory obligations, including gas safety and installation certification.
- To keep our records and, where you have agreed to it, to send you occasional updates.
Our lawful basis
We rely on contract where we are quoting for or carrying out work for you, legal obligation where certification or tax law requires us to keep records, legitimate interests in running and improving our business, and consent for any marketing messages. You can withdraw consent at any time.
Who we share it with
We do not sell your data. We share it only where necessary: with our accountant, with registration and certification bodies such as Gas Safe Register and MCS, with manufacturers when we register your warranty, with trusted subcontractors working on your job, with suppliers where materials are delivered to your property, and with service providers who host this website (Cloudflare) and deliver our email (Amazon Web Services). If you use our online boiler quote or heat pump estimate tools, the details you enter are processed by those tool providers to produce your quote. Where the law requires it, we may share information with public authorities.
How long we keep it
Enquiries that do not lead to work are deleted within 12 months. Records of completed work, including certificates, warranty records and invoices, are kept for at least 6 years to meet our legal and insurance obligations.
Your rights
Under UK GDPR you have the right to access the personal data we hold about you, to have it corrected or erased, to restrict or object to how we use it, and to receive it in a portable format. To exercise any of these, email us at hello@delta-flow.co.uk.
If you are unhappy with how we have handled your data you can complain to the Information Commissioner's Office at ico.org.uk or on 0303 123 1113.
