Privacy policy
How we handle your personal data when you use this website, in plain English first and then in full.
Last updated 26 June 2026.
The short version
- We only ask for what we need to answer your enquiry or book your appointment.
- We do not sell your data, and we do not run advertising trackers.
- Basic visitor counts are cookieless. Anything more detailed only happens if you opt in, and you can change your mind at any time from Cookie preferences in the footer.
- If you opt in, one of our analytics tools records a replay of your visit so we can see where the site is confusing. Form fields are masked, so what you type is not captured.
- You can ask us to show, correct, or delete your data at any time.
Who we are
Smart Energie Ltd is the data controller for the personal data described in this notice. We are registered in England and Wales (company number 14073778), with a registered office at Unit 27, Wadsworth Business Centre, Greenford, UB6 7LQ. We are registered with the Information Commissioner's Office (ICO) as a data controller.
For any question about your data, or to exercise a right below, contact us at info@smartenergie.co.uk or call 0800 999 1129.
The personal data we collect
We collect only what each part of the site needs to do its job:
- Enquiry and callback forms: your name, email address, phone number, postcode or address, and anything you choose to tell us about your home or project.
- Meeting bookings: if you book a call, your name, email and chosen time go to our booking provider so we can meet you.
- Our tools (quote, planner, payback, BUS eligibility, EPC lookup): the answers you enter. The figures are worked out in your browser. The EPC lookup sends only your postcode to the public government EPC register, never your contact details.
- Technical data: when you visit, our hosting and error-monitoring providers process limited technical information such as your IP address and browser type, to keep the site secure and working.
We do not ask for special-category data (such as health or financial account details) through this website, and we ask that you do not send it to us in free-text fields.
Why we use it, and our lawful basis
- To answer your enquiry, give you a quote, or arrange a survey or call: our legitimate interest in responding to you, and where relevant taking steps at your request before entering a contract.
- To send you marketing, only if you have opted in: your consent, which you can withdraw at any time.
- To count visits and see which pages are read, using cookieless analytics that cannot identify you: our legitimate interest in improving the site.
- To understand how people use the site in detail, including a replay of your visit: your consent, given through the cookie banner and withdrawable at any time from Cookie preferences in the footer. Nothing in this category runs until you opt in.
- To keep the site secure and diagnose faults: our legitimate interest in a safe, reliable service.
- To meet our legal, accounting and regulatory obligations: compliance with a legal obligation.
Who we share it with
We do not sell your personal data. We use a small set of carefully chosen processors to run the site and respond to you. Each only receives the data it needs for its task:
| Provider | What it does | Where | Data involved |
|---|---|---|---|
| Resend | Delivers your enquiry to our inbox | United States | Your name, email, phone and message |
| Cal.com | Runs the meeting-booking tool | United States | Only if you book: your name, email and chosen time |
| Vercel | Hosts the site and counts visits (cookieless) | United Kingdom | Page views and referrers. No cookie, no identifier, cannot single you out |
| Google Analytics | Shows which pages and channels bring enquiries. Only with your consent | United States | Cookie-based visit data, pages viewed, approximate location. Advertising and personalisation signals are switched off |
| Microsoft Clarity | Records a replay of your visit and builds heatmaps, so we can see where the site is confusing. Only with your consent | European Union (Ireland) | Mouse movement, scrolling, clicks, pages viewed. Form fields are masked, so what you type is not recorded |
| Sentry | Error monitoring so we can fix faults | United States | Technical and error data; not configured to capture your form content |
| EPC Open Data (MHCLG) | Government register for the optional EPC lookup | United Kingdom | Only your postcode, never your contact details |
| Postcodes.io (Ideal Postcodes) | Checks your postcode is valid in the quote and planner tools | United Kingdom | Your postcode only |
| Vercel | Hosts and serves the website | United States | Technical data such as IP address and request logs |
We may also disclose data where the law requires it, or to professional advisers acting for us under confidentiality.
Sending data outside the UK
Some of our providers are based outside the UK, including in the United States. Where your data is transferred outside the UK, we rely on appropriate safeguards recognised under UK data-protection law, such as the UK International Data Transfer Agreement or an adequacy decision, so your data keeps an equivalent level of protection.
How long we keep it
We keep enquiry and contact correspondence for up to 24 months after our last contact, unless you ask us to delete it sooner or we need it longer to meet a legal or contractual obligation. Where you become a customer, we keep records for as long as the law requires, including up to six years for financial and tax records. Visit recordings and heatmaps are deleted after 30 days. Consented analytics data is kept for up to 14 months. Cookieless visitor counts hold no personal information about you and are kept as aggregate totals only.
Cookies and session recording
We set no advertising cookies and never sell your data. Analytics cookies are off until you turn them on: when you first visit, a banner asks you to choose, and nothing beyond the essentials runs until you accept. Declining is one click, given the same prominence as accepting.
If you accept, two tools start. Google Analytics sets cookies so we can see which pages and search terms bring people to us, with advertising and personalisation signals switched off. Microsoft Clarity records a replay of your visit, showing mouse movement, scrolling and clicks, and combines visits into heatmaps. This helps us find pages where people get stuck.
Clarity masks form fields, so what you type into an enquiry form, including your name, address and phone number, is not captured in the recording. Recordings are deleted after 30 days.
You can change your mind at any time. Select Cookie preferences in the footer of any page to withdraw consent, which stops further collection immediately. We also count visits using a cookieless tool that sets no identifier and cannot single you out; because it holds no personal data, it runs whether or not you opt in.
If you open the meeting-booking tool, our booking provider may set cookies needed to run that tool; you only load it if you choose to.
Your rights
Under UK data-protection law you have the right to:
- Ask for a copy of the personal data we hold about you.
- Have inaccurate data corrected.
- Have your data erased, where there is no overriding reason to keep it.
- Restrict or object to how we use your data.
- Ask us to transfer your data to you or another provider.
- Withdraw consent at any time, where we relied on your consent.
To exercise any of these, email info@smartenergie.co.uk. We will respond within one month. If you are unhappy with how we have handled your data, you can complain to the Information Commissioner's Office at ico.org.uk, though we would welcome the chance to put things right first.
