    FuseBox Consumer Units

    Shop FuseBox consumer units (fuse boards) for modern UK installations, with options including RCBO consumer units, dual RCD boards, main switch boards and configurations with SPD protection. FuseBox boards are popular with electricians for straightforward installation layouts and a strong range of device and kit options.

    Choose a board based on the number of ways you need, the protection approach (RCBO vs dual RCD), and whether your spec calls for SPD protection or outdoor/IP-rated enclosures. For the best fit, use the filters and check the product datasheet for included devices, configuration details and compatibility.

    Looking for individual FuseBox protective devices instead of a complete board? Visit our FuseBox Shop to browse RCBOs, MCBs, RCDs, AFDDs, SPDs and accessories.

    Next Day Delivery

    Cut-Off Time and Order Information
    To ensure your order qualifies for next day delivery, please place your order by 3:00 PM. This is subject to all items being available on the shelf at the time of your order. For orders where the total value exceeds £150 + VAT (double our standard carriage-paid order value of £75 + VAT), we are happy to split the delivery into two shipments if some items are needed urgently and others are not immediately available. If you have any questions or need further assistance, feel free to reach out to us via WhatsApp for live support. We’re here to help!

    In Stock Delivery Policy

    Free Next-Day Delivery Over £75 + VAT:
    Orders above £75 + VAT qualify for free next-day delivery via DPD for in-stock items. While we strive for timely dispatch, we recommend placing orders early to avoid potential delays. Once dispatched, unexpected issues may arise despite the courier’s efforts.

    Orders Below £150 + VAT:
    To keep costs manageable, we dispatch your order once all items are ready, including products with longer lead times.

    Need items faster? You can pay for an additional delivery service to receive in-stock items sooner. Simply email us with your order details, and we’ll send you a payment link for the extra delivery cost.

    Orders Above £150 + VAT:
    For larger orders, we can split delivery at no extra cost. In-stock items will be sent immediately, with the remaining items dispatched once available.

    Backorder Delivery Policy

    Items with Lead Times (e.g., 1–3 Working Days):
    This means we need to source the product from our supplier before sending it to you. The estimated dispatch time is displayed on each product page.

    Out of Stock at Supplier:
    If an item is unavailable at the supplier, we will contact you promptly. You’ll have the option to choose an alternative product or request a full refund.
