This policy explains what personal data SE Knotweed collects when you use this website or contact us, how we use it, and the rights you have over it. SE Knotweed is the Japanese knotweed trading style of SE Environmental Ltd.
SE Knotweed is the Japanese knotweed trading style of SE Environmental Ltd, a company registered in England and Wales under company number 14314763, with its registered office at 44 Potternewton Mount, Leeds, West Yorkshire, LS7 2DR. We are the data controller for the personal data described in this policy. You can reach us by email at info@seknotweed.co.uk or by phone on 0800 852 7784.
When you send an enquiry through the form on our contact page, we collect the information you give us:
If you call or email us instead, we hold the information you provide in that message. Our website host also records standard technical information, such as your IP address and browser type, in its security logs.
We use your information to reply to your enquiry, arrange a survey, prepare a quotation and provide our knotweed services. We do not sell your personal data, and we do not use it for automated decision-making.
Our lawful bases under the UK GDPR are your consent when you submit the form, our legitimate interest in responding to and managing enquiries and running our business, and taking steps at your request to enter into a contract.
We use service providers who process data on our behalf under contract. Our enquiry form is provided by LeadSimplify. Our website is hosted on Cloudflare, and email to our domain is handled through Cloudflare Email Routing. We may also share information with our professional advisers, or where we are required to by law. We never sell or rent your data to anyone.
Some of our providers may process data outside the United Kingdom. Where that happens, we rely on the safeguards recognised under UK data protection law, such as the UK International Data Transfer Agreement, the UK Addendum to the EU Standard Contractual Clauses, or a UK adequacy decision.
We keep your enquiry for as long as we need it to deal with your request and for a reasonable period afterwards. If you become a customer, we keep records for as long as we need them to provide our services and to meet our legal, accounting and guarantee obligations. We then delete or anonymise the information.
Under UK data protection law you have the right to ask us for a copy of your data, to correct it, to delete it, to restrict or object to how we use it, and to receive it in a portable form. Where we rely on your consent, you can withdraw it at any time. To exercise any of these rights, email us at info@seknotweed.co.uk. We will respond within one month.
This website does not set its own advertising or analytics cookies. The enquiry form on our contact page is provided by LeadSimplify and may set cookies needed to run the form. If we add analytics or marketing tools in future, we will update this policy and, where the law requires it, ask for your consent first.
If you are unhappy with how we have handled your personal data, please contact us first so we can put it right. You also have the right to complain to the Information Commissioner's Office, the UK data protection regulator, at ico.org.uk or on 0303 123 1113.
We may update this policy from time to time. Any change will appear on this page, and the date at the top shows when it was last revised.
