How our trade window service works


Making a trade order

To make a trade order we will require your company or builders’ details alongside a full description of the window or door. Order acknowledgements will be provided for your review. 

Making a trade purchase 

To make a purchase, you’ll be directed to a dedicated account manager where a purchase order number or reference will be required. A contract or purchase order will be raised for your review. 

No accounts are being offered at present. All orders will require a 75% deposit at the time of ordering. 

Returns or order issues 

We do not accept returns unless the product has been supplied faulty. The windows and doors we supply will be made to bespoke specifications and sizes and will not be suitable for use elsewhere. Any faulty products or parts will be resupplied at Osborn’s own cost – refer to our T&Cs. Any faulty goods must be reported to the account manager or the main office within 24hrs of receipt. 

Which Suppliers/brands do we stock?

Any of our retail window suppliers can be supplied for your trade purposes. We only work with the best suppliers, namely John Fredericks, Roseview, Smart, Sollex and more. There is always a balance between cost and quality. Once we understand this, we will direct you to a suitable product.
