Help us understand the request
For an existing order, provide the order reference and the email address associated with it. A short explanation of the question is usually sufficient to begin a review.
For a product question, identify the model and the detail you would like clarified. If your concern relates to installation, describe the intended location and the information you need. Electrical compatibility or wiring work should be assessed using the product instructions and, where necessary, a qualified installer.
For an item that appears damaged, incomplete, incorrect, or defective, describe what you found. Clear photographs of the item, its label, and the affected area may help. If photographs are unavailable, tell us; we will explain another reasonable way to review the concern.
Our response commitment
After-sales requests are reviewed within 3 business days. Our response will explain the available next step or identify any information reasonably needed to continue.
This review period is distinct from the time required to complete a repair assessment, carrier investigation, return journey, or approved refund. Where an external process is involved, we will explain its relevance rather than treating the first response as a completed resolution.
For the service periods stated across these pages, business days mean Monday through Friday, excluding public holidays affecting the relevant service.
Keep correspondence useful and private
Please send only information relevant to your request. Do not include account passwords, unrelated identity documents, or other confidential material that is unnecessary for locating an order or understanding a product concern.
If we need further information, we will explain what is required and why. Please keep related messages in the same email conversation where possible so that the history of the request remains clear.
Written notices and returns
Company correspondence may be addressed to the business operator at the address shown at the top of this page. Physical returns require separate instructions.
Contact support before sending a product back. We will provide the appropriate destination and handling instructions for an approved return. Sending an item to an unconfirmed address can make it difficult to identify and process.
If a response has not arrived within the stated review period, check your unwanted-message folder and follow up in the original email conversation.
