Website usage data — when you visit our websites, we may automatically collect certain technical information, including your IP address, browser type and version, operating system, pages visited, time and date of your visit, and how you arrived at our site. This data is collected through cookies and similar technologies — see Section 7 for more detail.
Communications data — when you correspond with us by email, telephone or post, we retain a record of that correspondence.
We do not collect or process any special categories of personal data (such as data about health, religion or ethnicity) in connection with our website or standard business activities. If any special category data is relevant to a specific project or engagement, we will inform you separately and obtain your explicit consent where required.
3. How we collect your personal data
We collect personal data in the following ways:
Directly from you — when you submit an enquiry through our website contact form; when you contact us by email, telephone or post; when you provide us with your details as part of a project quotation, order or contract; and when you provide us with your business card or contact information at events or meetings.
Automatically — when you visit our websites, through cookies and similar technologies that collect technical information about your visit.
From third parties — in some cases we may receive your contact details from a third party, such as a referral from a business associate or from a public directory, where we have a legitimate reason to contact you in connection with our business.
4. How and why we use your personal data
We only use your personal data where we have a lawful basis to do so under the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018. The lawful bases we rely on are as follows:
Performance of a contract — where you have engaged us to provide goods or services, we use your personal data to perform that contract, including managing the project, communicating with you, processing payments and issuing invoices and documentation.
Legitimate interests — we may use your personal data where it is in our legitimate business interests to do so and those interests are not outweighed by your rights and freedoms. Our legitimate interests include: responding to enquiries submitted through our website; maintaining business relationships with customers, suppliers and partners; managing and improving our websites and services; and keeping records of our business activities for legal and administrative purposes.
Legal obligation — we may process your personal data where we are required to do so to comply with a legal obligation, such as providing information to HMRC, responding to a court order, or complying with health and safety or other regulatory requirements.
Consent — where we rely on your consent as the basis for processing (for example, in connection with optional marketing communications or non-essential cookies), you have the right to withdraw that consent at any time. Withdrawal of consent will not affect the lawfulness of any processing carried out before the consent was withdrawn.
We do not use your personal data to carry out automated decision-making or profiling that produces legal or similarly significant effects.
5. How long we keep your personal data
We retain personal data only for as long as is necessary for the purposes for which it was collected, in accordance with our internal data retention policy. As a general guide:
Enquiry data — where an enquiry does not lead to a contract, we retain contact and enquiry data for up to 24 months, after which it is securely deleted.
Customer and project data — we retain personal data relating to customers and completed projects for a period of seven years following completion of the relevant contract, in line with standard legal and accounting requirements.
Supplier and contractor data — we retain personal data relating to suppliers and contractors for a period of seven years following the end of the relevant working relationship.
Website usage data — anonymised website analytics data may be retained for longer periods for statistical analysis. Personal data collected via cookies is retained in accordance with the timescales set out in our cookie settings.
Where we are subject to a legal obligation to retain data for a specific period, we will comply with that obligation. At the end of the relevant retention period, personal data is securely deleted or anonymised.
6. Who we share your personal data with
We do not sell your personal data to third parties. We may share your personal data with the following categories of recipients, where necessary:
Service providers and data processors — we use third-party service providers to support our business operations, including IT and hosting providers, accounting and invoicing software, and website analytics providers. These providers process personal data on our behalf and are bound by data processing agreements that require them to keep your data secure and to use it only for the purposes we specify.
Professional advisers — we may share personal data with our solicitors, accountants, insurers and other professional advisers where necessary in connection with the services they provide to us.
Regulatory and legal authorities — we may disclose personal data to regulators, government bodies or law enforcement agencies where we are required to do so by law or where disclosure is necessary to protect our legal rights or those of a third party.
Business transfers — if SDE Group or any of its divisions is acquired, merged or restructured, your personal data may be transferred to the relevant successor entity as part of that transaction.
We require all third parties who receive your personal data to respect its security and to treat it in accordance with applicable data protection law.

Analytics cookies — these allow us to count visits and understand how visitors move around our websites, helping us to improve the user experience. We use analytics tools such as Google Analytics for this purpose. The information collected is aggregated and anonymous. We will only set analytics cookies with your consent.

8. International data transfers
We store and process personal data primarily within the United Kingdom. Where we use third-party service providers that transfer personal data outside the UK, we ensure that appropriate safeguards are in place in accordance with the UK GDPR and any applicable UK international data transfer agreements or adequacy decisions recognised by the UK government. We do not transfer personal data internationally without ensuring that a lawful transfer mechanism applies.
9. Your rights
Under UK data protection law, you have the following rights in relation to your personal data:
Right of access — you have the right to request a copy of the personal data we hold about you and information about how we use it. This is known as a Subject Access Request (SAR). We will respond within one month of receiving a valid request, though in complex cases we may extend this by a further two months, in which case we will notify you.
Right to rectification — you have the right to request that we correct any inaccurate or incomplete personal data we hold about you.
Right to erasure — you have the right to request that we delete your personal data in certain circumstances, for example where it is no longer necessary for the purpose for which it was collected, or where you withdraw consent and we have no other lawful basis for processing.
Right to restrict processing — you have the right to ask us to restrict how we use your personal data in certain circumstances, for example while we verify the accuracy of data you have disputed.
Right to data portability — where we process your personal data on the basis of your consent or in performance of a contract, and the processing is carried out by automated means, you have the right to receive your personal data in a structured, commonly used and machine-readable format.
Right to object — you have the right to object to processing of your personal data where we rely on legitimate interests as the lawful basis, and where you believe your interests, rights or freedoms override ours. You also have an absolute right to object to your personal data being used for direct marketing purposes.
Rights relating to automated decision-making — you have the right not to be subject to a decision based solely on automated processing that produces legal or similarly significant effects. As noted in Section 4, we do not carry out such processing.
To exercise any of these rights, please contact us at info@sde-group.co.uk or in writing to our registered address. We may need to verify your identity before processing your request. We will not charge a fee for handling your request unless it is manifestly unfounded or excessive.
