Privacy Policy

1. Who we are

Sash Timber Windows ("we", "us", "our") is a timber window and door specialist serving homes across South West London, including Wandsworth, Clapham, Balham, Wimbledon, Putney, Fulham, Richmond and the surrounding SW postcodes. We are the data controller of the personal information you provide through this website.

If you have any questions about this policy or how we handle your data, contact us at info@sashtimberwindows.co.uk or call 020 4652 9820.

2. What information we collect

We collect personal information you give us directly when you:

• Request a quote or free survey (name, phone number, email address, postcode, property details and your message)
• Use our instant estimate or price calculator (contact details, postcode and details of the windows or doors you are enquiring about)
• Contact us by phone, email or WhatsApp

We also collect limited technical information automatically when you browse the site, such as your device type and pages visited, to keep the website working and secure. See the Cookies section below.

3. How we use your information

• To respond to your enquiry, provide estimates and arrange surveys and quotations
• To carry out and administer any work you instruct us to do
• To send you an email notification confirming your enquiry has been received
• To keep records required for guarantees, insurance and legal compliance (for example FENSA certification)
• To operate, secure and improve this website

Our lawful bases under UK GDPR are: taking steps at your request before entering into a contract, performance of a contract, our legitimate interests in running our business and website, and compliance with legal obligations. We do not sell your personal information, and we do not send marketing emails without your consent.

4. Who we share it with

We only share your information where necessary:

• With trusted service providers who host our website and deliver our email notifications, acting on our instructions
• With surveyors, fitters and suppliers involved in delivering your project
• With certification bodies such as FENSA where your installation requires registration
• Where required by law, regulation or a court order

5. How long we keep it

We keep enquiry details for up to two years so we can follow up on your project. If you become a customer, we keep records for the duration of your guarantee and for as long as required by law (typically six years for contractual and tax records). We then securely delete or anonymise your information.

6. Cookies and similar technologies

This website uses only essential browser storage needed for it to function — for example, remembering your cookie preferences and briefly carrying your estimate result between pages while you complete an enquiry. These do not track you across other websites.

If we introduce analytics or marketing cookies in the future, we will ask for your consent first via the cookie banner and update this policy.

7. Your rights

Under UK data protection law, you have the right to:

• Access a copy of the personal information we hold about you
• Ask us to correct inaccurate information
• Ask us to delete your information
• Object to or restrict how we use your information
• Data portability, where applicable
• Withdraw consent at any time, where we rely on consent

To exercise any of these rights, email info@sashtimberwindows.co.uk. You also have the right to complain to the Information Commissioner's Office (ICO) at ico.org.uk or on 0303 123 1113.

8. Security

We use appropriate technical and organisational measures to protect your personal information, including encrypted connections (HTTPS) and access controls, and we limit access to those who need it to deal with your enquiry or project.

9. Changes to this policy

We may update this policy from time to time. Any changes will be published on this page with a revised "last updated" date.
