Website terms
Last updated 6 August 2026. These terms govern your use of this website. They are not your contract with us for supply and installation — that is a separate document you receive with your quotation.
Who we are
- DemandOS Ltd, trading as WindowStandard, registered in England and Wales
- Company number: 17351268
- Registered office: 26 North Parade, York, YO30 7AB
- VAT number: [SET, or delete this line if not VAT registered]

Our role — please read this one
WindowStandard does not manufacture, supply or install windows and doors. We run the brand and introduce you to a single vetted installation company covering your area.
Any contract for supply and installation is between you and that installer, not between you and us. They survey your property, they quote, they carry out the work, they register it under building regulations, and they provide the guarantee. Their own terms and cancellation notice apply to that contract, and they will give those to you in writing before you commit to anything.
What we are responsible for is the introduction: that the installer has been checked, that your enquiry goes to one firm rather than several, and that the information on this site is accurate. If an installer lets you down, tell us. We cannot perform their contract for them, but we can and do remove firms from the network.
Quotations
Quotations come from your installer, not from us. They are subject to survey and valid for the period stated on the quotation itself. Where a survey reveals structural work, unusual access or other conditions not apparent at the time of quoting, your installer should tell you and re-quote before any work begins, and should not carry out extra chargeable work without agreeing it with you first. If that does not happen, we want to hear about it.
Design Before You Buy
The visualisation we prepare is an artist's impression produced to help you picture the finished result. It is an illustration, not a technical drawing or a specification. Colours shown on a screen will differ from the finished product, and the visualisation does not form part of any contract between us.
Your rights when you order
Where you enter into a contract at your home or at a distance, you have a statutory right to cancel within 14 days under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. That right applies to your contract with the installer, and the full details — including how to exercise it and what happens if you ask for work to begin within the cancellation period — must be given to you in writing by them before you commit.
If you are not given a cancellation notice, say so before you sign anything.
Nothing on this website limits your statutory rights under the Consumer Rights Act 2015.
Installation and building regulations
Replacement windows and doors are notifiable under building regulations. Your installer is responsible for certifying the work and giving you the documentation on completion. Ask them at survey which scheme they register under and what paperwork you will receive.
Using this website
The content of this site is provided for general information. We take care to keep it accurate but do not warrant that it is complete or current, and you should not treat it as advice on your particular property. The guides in our Learning Centre are general in nature; planning and conservation rules vary by property and by local authority.
All content, design, images and the Design Before You Buy name are ours or licensed to us. You may view and print pages for your own use. You may not reproduce them commercially without our written permission.
Availability
We do not guarantee that the site will always be available or free from error, and we may change or withdraw any part of it without notice.
Liability
We do not exclude or limit our liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot lawfully be excluded. Subject to that, we are not liable for any loss arising from reliance on the general information published on this website, as distinct from the written quotation and contract given to you by your installer. We are not party to that contract and do not perform the installation work.
Complaints
If something goes wrong, contact us at hello@windowstandard.co.uk and we will deal with it. If the complaint concerns the work itself, raise it with your installer first, since the contract is with them — but tell us as well, because how installers handle problems determines whether they stay in the network.
Governing law
These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction.
Before this page goes live. Under the introducer model the consumer sales contract sits with the installer, which moves most of the 2013 Regulations exposure to them — but it does not remove yours. Two documents still need a solicitor: the installer agreement (vetting standards, what they must give the customer, how enquiries are handled, grounds for removal, data-sharing terms), and a short check of this page against the introducer framing. Get the installer agreement right and it is the thing that makes the network defensible.
