Delivery

Delivery Terms & Conditions

1. Delivery Inspection

Please ensure that all products are carefully checked at the time of delivery. Any breakages or damages must be clearly stated on the delivery note. This is essential, as all deliveries are insured against damage, and doing so allows for a swift response from our customer service team.

Important:

If you sign for a delivery without noting any damage, we reserve the right to refuse replacements or refunds for any broken items.

In case of damage:

Inspect the delivery thoroughly.
If any items are damaged, mark the delivery note as “damaged” and sign it.
If you have not signed the delivery not “damaged”, we reserve the right to refuse any replacements.
Inform us immediately of any damage.
We may request written confirmation of the issue within 48 hours of delivery.
Take digital photos of the damaged items.
These images are necessary for processing insurance claims and should be sent to us as soon as possible.

If someone else is receiving the delivery on your behalf, they must be fully informed of these conditions.

2. Delivery Company & Site Access
All deliveries are subcontracted to national pallet networks, which operate through central hubs and independent local depots across the country. As a result, Otto Tiles cannot guarantee delivery on a specific date, and cannot be held responsible for late deliveries or any delays or costs resulting from them.
At the time of your order, please inform us of any site restrictions that could affect delivery. Our delivery vehicles are typically large, and any obstructions (e.g., parked cars, narrow roads) should be cleared in advance.
You must notify us of any potential issues, including:

Parking restrictions
Congestion charges
Narrow lanes or roads
Slopes or steep driveways
Height restrictions
Weak or weight-limited bridges

You may be charged for redelivery if we are not informed of these in advance.

We strongly recommend that you do not schedule trades people for installation on the delivery day, as Otto Tiles will not be liable for any costs arising from delayed delivery.

3. Curbside Delivery

Please note that delivery drivers are not permitted to move products inside your property or site. All deliveries are curbside only and will be off-loaded at the nearest suitable point to your address, which may be the roadside.
For orders over 150 sq ft, please be aware that larger pallets and heavier loads may be involved.

Anything you can do to help facilitate a smoother drop-off closer to your property is appreciated.

You (or someone on your behalf) must be present to receive the delivery.
If no one is available, the delivery will not be off-loaded, and additional redelivery charges will apply.

Please ensure all goods are checked upon delivery and that the delivery note is signed appropriately.

We will not accept claims if the delivery note is signed “unchecked.”

4. Pallets & Crates

Your order will typically arrive on pallets or in crates, which are considered part of your delivery.
Otto Tiles is not responsible for removing pallets or crates from your site, unless specifically agreed beforehand.

All deliveries are curbside and require a scheduled appointment. Delivery does not include unpacking or bringing tiles indoors. Make sure someone is present to inspect and sign for the shipment.

Why is shipping so expensive?

Tiles are heavy and fragile. Orders are palletized and shipped via freight to minimize breakage. Each box can weigh 35–50 lbs, and we use shrink wrap and pallets for safety.

Once your order reaches the nearest service center, the freight carrier will contact you to schedule delivery. You must respond within 24 hours to avoid storage fees.
