Legal
Every document that governs buying from us, written to be read rather than to be survived. Each one opens with a plain-English summary and says what law it is written against.
Most legal sections are written to be defensible. We have tried to write ones that are also checkable: every clause about your data names the database table it describes, every regulatory claim names the regulation, and where we promise more than the law requires, it is marked as a promise rather than disguised as a restatement of the law.
If any of it is unclear, ask — hello@duneair.com. A term you had to email us about is a term we wrote badly, and we would rather fix it than explain it twice.
Buying from us
The contract itself, and the three parts of it people most often need to find on their own.
Terms of sale
The contract between you and us when you buy a system, a survey or AirCare: what you get, what it costs, what happens after you pay, and what we owe each other if something goes wrong.
Updated 20 August 2026Cancelling and refunds
Your 14-day right to change your mind, how to use it, what happens if you asked us to start early, and when the right ends.
Updated 20 August 2026Guarantees and warranties
The three separate promises that cover your system — your statutory rights, our workmanship guarantee, and the manufacturer warranty — and what each one actually covers.
Updated 20 August 2026AirCare plan terms
The rolling monthly service plan: what the £14 covers, when it starts, what it does not include, and how to stop it.

Your data
What we hold, what we set in your browser, and how to complain about either.
Privacy notice
What we hold about you, why we are allowed to, who else touches it, how long we keep it, and how to make us stop. Written against the actual database rather than from a template.
Updated 20 August 2026Cookie notice
The two cookies this site sets, why they are exempt from needing your consent, and what would have to change for that to stop being true.
Updated 21 August 2026Complaints
How to complain about the work or about how we handled your data, what we do when you do, and how long each step takes.

Working with us
For engineers applying to fit for us, rather than for customers.
Installer application terms

Also worth knowing
Our accessibility statement is not a legal document — no private company is required to publish one — but it is written to the same standard and belongs in the same place in your head.
