Privacy Policy

Welcome to the website operated by Envair Technology Limited (company number and registration details available on request), trading as Envair Technology (together, "we", "us", or "our"). We recognise that privacy matters—particularly when you share drawings, monitoring data, or operational information about your buildings. This policy explains how we handle personal data and project information when you use our site or instruct us to deliver ventilation and indoor air-quality services.

Project data and technical records

In the course of surveys, commissioning, and indoor air-quality programmes, we routinely process confidential technical material, including but not limited to O&M manuals, trend logs, BMS exports, floor plans, and photographs of plant rooms ("Project Data"). Project Data is used solely to scope, deliver, and document the professional services you commission. Access is limited to personnel and sub-consultants who need it to perform their duties, all of whom are bound by confidentiality and data-protection obligations appropriate to UK processors.

Personally identifiable information

"Personally identifiable information" means information that identifies or can be used to identify, contact, or locate an individual—such as name, work email, telephone number, job title, and professional address. It may also include billing details where you contract directly with Envair Technology Limited.

What personally identifiable information do we collect?

We collect basic profile information from all website visitors (for example, through analytics technologies described below). When you submit an enquiry form, request a proposal, or engage us for services, we may collect your name, organisation, role, email address, telephone number, site addresses, and details of your ventilation or IAQ objectives.

How do we use personally identifiable information?

We use this information to respond to enquiries, prepare quotations, deliver contracted engineering services, issue invoices, and—where you have not opted out—send operational updates that are relevant to buildings we support. We do not use your data for unrelated marketing without a clear lawful basis and an opportunity to withdraw consent.

With whom may information be shared?

We do not sell or rent personally identifiable information or Project Data. We may share limited information with accredited subcontractors (for example, specialist laboratories or equipment vendors) strictly where required to execute your instruction. We may also share aggregated, anonymised statistics for sector benchmarking, provided no individual or identifiable site can be inferred from those statistics.

Storage, security, and retention

Personally identifiable information and Project Data are stored on access-controlled systems with encryption in transit where technically feasible. Retention periods reflect statutory, contractual, and professional indemnity requirements—typically for the duration of the engagement plus a defined archive window. While we apply commercially reasonable safeguards, no online service can guarantee absolute security.

Cookies and similar technologies

Our website may use cookies or analogous technologies to maintain session state, remember preferences, and understand how visitors navigate our content. Analytics tools may process IP addresses and device metadata in pseudonymised form. You can control cookies through your browser; disabling them may limit certain interactive features.

Your rights

Under UK data protection law you may have rights to access, rectify, erase, restrict, or object to certain processing, and to lodge a complaint with the Information Commissioner's Office. To exercise any right, or to correct inaccuracies, please contact us using the details on our contact page.

Deletion requests

Where deletion is compatible with our legal and insurance obligations, we will honour requests to remove personal data from active systems. Residual copies may persist for a limited period in encrypted backups.

Children's privacy

Our services are directed at commercial and institutional clients. We do not knowingly collect personal information from anyone under 18. If you believe a minor has submitted data to us, please notify us promptly so we can remove it.

Compliance with law

We may disclose information when required by court order, regulator, or competent law-enforcement authority, or when necessary to protect the vital interests of individuals using the buildings we advise on.

Changes to this policy

We may update this privacy policy to reflect new services, legal requirements, or security practices. Material changes will be posted on this page with an updated effective date. Where a change affects processing you have previously restricted, we will contact you where practicable.

External links

Our site may link to third-party resources. Those sites maintain their own privacy practices; we encourage you to review them before submitting personal information.
