Terms of use

Last updated 8 August 2026

1. Who we are

This website is operated by DemandOS Ltd, trading as WindowStandard. By using the site you accept these terms. If you do not accept them, please do not use the site.

2. What WindowStandard does

WindowStandard operates a consumer brand that generates enquiries from homeowners and passes them to vetted installation businesses. We are an introducer, not an installer. We do not manufacture, supply, survey, install, certify or guarantee any product or work.

Where you proceed with an installer, the contract for the survey, the goods and the installation is between you and that installer. They are responsible for their quotation, their workmanship, their guarantees, their certification under any competent person scheme, and their compliance with consumer law. WindowStandard is not a party to that contract and does not act as the installer's agent.

3. What we ask of installers

Businesses carrying the WindowStandard name agree to standards covering response times, free no-obligation surveys, itemised written quotations, your statutory cancellation rights, an absence of pressure selling, certification of the work, and a complaints procedure. These are contractual obligations we place on them. They do not make us responsible for the installer's performance, but we do want to know when they are not met — tell us at enquiries@windowstandard.co.uk.

4. One enquiry, one installer

We pass your enquiry to a single installation business. We do not sell the same enquiry more than once, and we do not pass it to competing firms.

5. Using the site

• You may use the site for your own personal, non-commercial purposes.
• You must not submit false, misleading or third-party details, or an enquiry you have no genuine intention of pursuing.
• You must not attempt to interfere with the site, extract data from it by automated means, or use it in any unlawful way.
• Any images you upload must be yours to share.

6. Information on this site

Descriptions, comparisons and guides are published in good faith as general information. They are not advice about your particular property, and specifications and availability vary by installer. Nothing on this site is a quotation or an offer to contract. Any figure or estimate given is illustrative and not a price.

7. The visualiser

The design visualiser is an illustrative tool. Colours and finishes shown on screen are an approximation and will not exactly match a manufactured product. It is not a specification, a survey or a quotation.

8. Intellectual property

The WindowStandard name, logo, site design and content belong to DemandOS Ltd or its licensors. You may not copy or reuse them without permission.

9. Our liability

Nothing in these terms limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot lawfully be limited. Your statutory rights as a consumer are not affected.

Subject to that, we are not liable for the acts, omissions, workmanship, quotations or guarantees of any installer, and we do not accept liability for indirect or consequential loss arising from your use of this site.

10. Links

Where we link to another website we are not responsible for its content.

11. Changes and termination

We may change these terms, in which case the updated version is posted here. We may withdraw or suspend the site at any time.

12. Law

These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction. If you live in Scotland or Northern Ireland you may bring proceedings in your own jurisdiction.

13. Complaints

Complaints about a survey, a quotation or installation work should go to the installer under their own complaints procedure. If you want us to know about it as well, email enquiries@windowstandard.co.uk — we take that seriously, because the brand is only worth what the installers behind it do.
