4. Who we share information with
We share relevant information only where necessary for the purposes described above. Recipients may include:
Instool and OpenSolar, which we use for job administration, design, quotations and installation records.
Suppliers, delivery companies and subcontractors involved in your project.
Equipment manufacturers and warranty providers.
IWA and relevant insurers, where needed to arrange deposit protection, guarantee insurance or handle a claim.
MCS and our Certification Body, where your installation falls within the MCS scheme.
Your electricity Distribution Network Operator and relevant Building Control or competent-person scheme providers.
Providers of website hosting, email, IT, accounting and payment services.
Professional advisers, regulators or public authorities where necessary or legally required.
For MCS installations, we provide relevant customer contact and installation details to MCS for registration and certification. MCS may contact you about your installation and customer experience.
Some recipients act as independent controllers and explain their own use of information in their privacy notices. Service providers acting on our behalf must handle information under appropriate contractual arrangements.
5. How long we keep information
We keep personal information only for as long as needed for the purpose for which it was collected, including relevant legal, certification, warranty and dispute requirements.
Enquiries that do not become installations: Normally retained for 24 months from our last meaningful contact with you, unless there is a legal, regulatory or legitimate business reason to retain the information for longer.
Installation and certification records: at least six years to meet applicable MCS record requirements. For commercial contracts, the supplied MCS Customer Commitment requires retention for at least six years from the end of the last company financial year to which the records relate, or longer where the contract requires it.
Guarantee, warranty and complaint records: for as long as reasonably necessary to administer the relevant guarantee, resolve the complaint and meet applicable recordkeeping or claims requirements.
Marketing preferences: for as long as needed to respect your choices. We may retain a minimal suppression record after you opt out to avoid contacting you again.
Where we retain information for longer, we consider the applicable obligation, guarantee period or ongoing dispute. We securely delete or anonymise information when it is no longer needed.
6. Keeping your information secure
We use appropriate technical and organisational measures to protect personal information from unauthorised access, loss, misuse or disclosure.
Access is limited to people and service providers who need it for their work. We review our arrangements to help keep information secure.
7. Marketing
Sending an enquiry or requesting a quotation does not automatically subscribe you to promotional emails.
Where we seek your consent to receive marketing, the choice will be separate and optional. You can withdraw consent at any time using the unsubscribe option in our emails or by contacting evan@wrensolar.co.uk.
Withdrawing marketing consent does not prevent us from sending necessary communications about your quotation, installation, warranty or ongoing service.

Depending on the circumstances, you may have the right to:
Request access to your personal information.
Ask us to correct inaccurate or incomplete information.
Ask us to delete information.

Withdraw consent where we rely on it.
You also have the right to object to processing based on legitimate interests, on grounds relating to your circumstances. You can object to direct marketing at any time.
These rights are subject to applicable conditions and exemptions. Contact evan@wrensolar.co.uk to make a request. We may need to verify your identity before responding.
