Privacy Policy
Last updated: August 2026
This policy explains what information Cavity Wall Extraction UK collects when you use this website, why we collect it, and what your rights are.
Who we are
Cavity Wall Extraction UK provides cavity wall insulation extraction services across England and Wales. This website is cavitywallextractionuk.co.uk.
What we collect
When you submit the survey request form on this site, we collect:
- Your name
- Phone number
- Email address
- Postcode
- Any details you choose to add about your property or the problem
We also use cookies and similar technologies to understand how visitors use the site and to measure the performance of our advertising. Some of these only run if you accept them via the cookie banner.
How we use your information
We use the details you submit to contact you about your enquiry, arrange a survey, and provide a quote. We do not sell your information to third parties.
Cookies and advertising
With your consent, we use Google Analytics and Google Ads to understand how people find and use this site, and to measure whether our advertising is working. You can withdraw consent at any time by clearing your cookies and revisiting the site, which will show the cookie banner again.
How long we keep your data
We keep enquiry details for as long as reasonably needed to respond to your enquiry and, if you become a customer, for as long as required for the job and our legal and accounting obligations.
Your rights
Under UK data protection law, you have the right to ask what information we hold about you, request a copy of it, ask us to correct it, or ask us to delete it. To do this, contact us using the details below.
Who is responsible for your data
Cavity Wall Extraction UK is the data controller for the personal data described in this policy. You can reach us by email at cavwallextraction@gmail.com.
Our lawful basis for using your data
We rely on legitimate interests to respond to an enquiry you have sent us, because you have asked us to quote for work and it is reasonable for you to expect a reply. We rely on consent for non-essential cookies and advertising measurement, which you give or refuse through the cookie banner and can change at any time. We rely on contract where you go on to book work with us, and on legal obligation for our accounting and tax records.
How long we keep it
Enquiries that do not become jobs are deleted within 24 months. If you become a customer, we keep job and payment records for 7 years to meet HMRC requirements. Cookie consent is remembered for 180 days, after which you are asked again.
Cookies we use
| Cookie | Set by | Purpose | Expires |
|---|---|---|---|
| cwe_consent | This site | Remembers your cookie choice. Strictly necessary, set without consent. | 180 days |
| _ga, _ga_* | Google Analytics | Measures how visitors use the site. Only set if you accept. | Up to 2 years |
| _gcl_* | Google Ads | Attributes an enquiry to the ad you clicked. Only set if you accept. | Up to 90 days |
Where your data goes
Form submissions are processed by Netlify, who host this site, and delivered to us by email. Measurement and advertising data is processed by Google through Google Analytics, Google Ads and Google Tag Manager. Both are based in the United States, so accepting non-essential cookies involves a transfer of data outside the UK. These transfers rely on the UK Addendum to the EU Standard Contractual Clauses and the UK Extension to the EU-US Data Privacy Framework.
Withdrawing your consent
You can change or withdraw your cookie consent at any time using the cookie settings link, which reopens the banner. Withdrawing is as easy as giving consent and does not affect anything processed before you withdrew.
Contact us, and your right to complain
If you have any questions about this policy or how your data is handled, email cavwallextraction@gmail.com.
If you are not happy with how we have handled your data, you have the right to complain to the Information Commissioner's Office at ico.org.uk/make-a-complaint, by phone on 0303 123 1113, or at Wycliffe House, Water Lane, Wilmslow, Cheshire SK9 5AF.
