Returns & Refunds

Last updated: 22 July 2026

1. Made-to-Order Units

Sealed units and processed glass are manufactured to your specification and sizes. As bespoke goods made to order, they are non-returnable and non-refundable unless faulty, damaged in transit, or supplied incorrectly by us. Please check all sizes and specifications carefully before ordering.

2. Damage in Transit

Inspect every unit on delivery and note any damage on the delivery paperwork. Transit damage must be reported within 24 hours and shortages within 48 hours, with photographs where possible. Confirmed transit damage is replaced free of charge on our standard lead time.

3. Manufacturing Faults & Warranty

All sealed units carry a 5-year warranty against seal failure (condensation within the cavity) under normal installation and use. Faulty units are replaced free of charge. The warranty excludes glass breakage after delivery, incorrect installation, and site damage. See your order confirmation or our Terms and Conditions for full terms.

4. Incorrect Supply

If we supply a unit that does not match your confirmed order, we will remake and redeliver it free of charge. Please report any discrepancy within 48 hours of delivery so we can resolve it quickly.

5. Stock Accessories

Unused stock accessories in their original packaging may be returned within 14 days of delivery for a credit or refund, subject to inspection. Return carriage is the customer’s responsibility unless the item was supplied in error.

6. How to Make a Claim

Email sales@csultd.co.uk or call 020 8574 9342 with your order number, a description of the issue and photographs. We aim to acknowledge claims within one working day and resolve them as quickly as possible.
