1st July 2026 Price Increase Notification
Dear Valued Customer
I am writing to advise you of a price increase across Dimond’s range of manufactured Roofing and Rainwater products.
Despite working closely with our suppliers, ongoing increases across our material and manufacturing costs mean we can no longer absorb these cost increases.
As a result, we are advising of a price increase effective from 1 October 2026. The following increases will apply:
Long Run Products
• Pre-painted steel long run, rainwater products and flashings: 3% - 5%
• Unpainted steel long run, rainwater products and flashings: 2% - 4%
• All steel-based roofing and rainwater accessories: 3% - 5%
Current pricing will remain for all orders dispatched prior to 30 September 2026. Existing commercial and project quotations issued prior to this notice will remain valid for 60 days from their date of issue. Any new quotes for work commencing on or after 1 October 2026 will be quoted at our new rates.
We value your business and look forward to continuing to support your projects. If you have any questions or wish to discuss upcoming projects in your pipeline, please don't hesitate to contact your Account Manager or local branch.
Kind Regards,
Damien Sauni
General Manager
