How Advanced Sash Windows handles your information, and what this website does and does not track. Last updated 13 November 2026.
Who we are
Advanced Sash Windows Ltd (trading as Sashworx), 5 St Andrews Road, Maidstone, Kent ME16 9AN. Registered in England & Wales, company number 11598336. We are the data controller for the information described on this page. Email info@sashworx.co.uk or call 01622 470019.
What we collect, and why
When you ask for a quote — your name, phone number, email address, the address of the property and anything you tell us about the windows, including photographs you send. We use it to survey the job, price it and carry out the work. The lawful basis is taking steps at your request before entering a contract, and performing that contract once you accept a quote.
When you call, email or WhatsApp us — the contents of that conversation and your contact details, so we can answer you.
When you visit this website — our host and security software record your IP address and basic request details in server logs, to keep the site running and to block attacks. The lawful basis is our legitimate interest in site security.
Cookies we use
This site sets no analytics, advertising or tracking cookies. There is no Google Analytics, no advertising pixel and no third-party tracker on these pages.
The only cookies set are strictly necessary ones: a security cookie from our firewall (Wordfence) if it needs to check your request, and WordPress session cookies if you log in to the site as an administrator. Strictly necessary cookies do not require consent.
Third-party content
Google Maps on our contact page is not loaded until you click to load it. Once you do, Google receives your IP address and may set its own cookies in your browser, under Google’s privacy policy. If you never click, nothing is sent to Google.
Google Fonts are loaded from Google servers so the site displays in the right typefaces. This passes your IP address to Google but sets no cookies.
WhatsApp links simply open WhatsApp; we receive only the message you choose to send.
How long we keep it
Quotes and enquiries that do not become jobs are kept for up to two years, in case you come back to us. Records of completed work, including invoices, are kept for six years to meet HMRC requirements. Photographs of your windows are kept as part of the job record; we only use them publicly on this website or on social media if you have given us permission.
Who we share it with
We do not sell your information and we do not share it for marketing. We share it only with our web host and email provider as part of running the business, our accountant where an invoice requires it, and anyone we are legally obliged to tell. Where we are working as a subcontractor, we share job information with the main contractor or managing agent who engaged us.
Your rights
You can ask us for a copy of the information we hold about you, ask us to correct it, ask us to delete it, or object to how we are using it. Email info@sashworx.co.uk and we will respond within one month. If you are not satisfied, you can complain to the Information Commissioner’s Office at ico.org.uk or on 0303 123 1113.
Controlling cookies yourself
You can block or delete cookies in your browser settings at any time. Because this site relies on none for its content, blocking them will not stop the site working — you may just need to click to load the map again.
