    AFDD Arc Fault Detection Devices for Safer Installations

    Arc Fault Detection Devices (AFDDs) help reduce the risk of electrical fires by detecting dangerous arc faults and disconnecting the circuit before heat builds up. They’re commonly selected for new builds, consumer unit upgrades and retrofit work where additional fire protection is required or strongly recommended.

     

    BS 7671 (18th Edition) Guidance: Where AFDDs Are Required or Recommended

    Under BS 7671:2018 + A2:2022, AFDD protection is required for final circuits supplying socket-outlets up to 32A in certain higher-risk settings (including Higher Risk Residential Buildings, HMOs, purpose-built student accommodation and care homes). For most other premises, AFDDs are recommended based on design and risk assessment.

     

    Choose the Right AFDD for Your Consumer Unit

    Use the filters on this page to match your spec quickly, including:

    Product type: AFDD only, AFDD + MCB, or AFDD + RCBO

    Current rating: 6A–40A, with B or C curve options

    Breaking capacity: 6kA or 10kA

    RCD protection: Type A, typically 30mA, and 1P + switched neutral formats

    Special features: including bi-directional models

    AFDD Brands Available

    Shop AFDDs from leading manufacturers including FuseBox, Hager, Live Electrical, Niglon, WCED and Garo, with options for different board types and common UK installation requirements.

     

    Fast UK Delivery & Support

    Orders over £75 + VAT qualify for free next-day delivery on in-stock items, with a 3pm cut-off (subject to availability). If you need help choosing the right AFDD for your board or circuit design, you can message the team on WhatsApp.

    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.
