At coppercylinder.co.uk we keep our prices low by manufacturing all orders received through our store rather than keeping stock of vented copper cylinders.

  1. Can't fault the service! 5 Star Review

    Posted by on 13th Jan 2021

    Ben could not have worked harder to sort out return and replacement of leaky tank that slipped through manufacturers QC. Delivery to remote location (both times) as expected, product exactly as ordered, communication at all stages quick and effective, local supplier couldn't match price for non-standard options. Particularly like ability to customise order to exactly suit requirements. Will be ordering again, cheers Ben!

  2. Ben is so helpful and friendly 5 Star Review

  3. Exactly as specified, prompt and a reasonable price 4 Star Review

    Posted by on 13th Feb 2016

    I had my doubts about ordering a cylinder with specific locations for the fittings by mail order but when received I found it exactly as I'd specified; it was made and delivered within three days and all done at a reasonable price.
