    What Is a Consumer Unit?

    A consumer unit (also known as a fuse board) is the hub of your property’s electrical system. It distributes power to individual circuits and protects each one using devices such as MCBs, RCDs, or RCBOs.

    All our units comply with the 18th Edition Wiring Regulations (BS 7671), including:

    • Non-combustible metal enclosures
    • RCBO or RCD circuit protection
    • SPD surge protection where required
    • Clear circuit labelling and safety markings

    Whether you’re wiring a new build, upgrading an old fuse box, or adding capacity to a garage or extension, we’ve got a solution that works.

     

    Our Range of Domestic Consumer Units

    We stock over 280 configurations — here’s what you’ll find:

    • Main switch consumer units – clean, simple layouts
    • RCBO fuse boards – protection per circuit, no nuisance tripping
    • Garage consumer units – smaller units for outhouses or external installs
    • 18th Edition metal fuse boards – required by UK regulations
    • SPD-protected models – with built-in surge protection
    • Populated fuse boxes – pre-installed breakers, ready to go

    We also carry a full range of accessories: blanking plates, SPD modules, tail kits, and more.

    Frequently Asked Questions

    What is a consumer unit?

    A consumer unit (or fuse box) distributes electricity across your property and includes protective devices like RCBOs or RCDs to prevent faults and overloads.

    Are all consumer units metal now?

    Most domestic consumer units must be metal.
    As per BS 7671 Regulation 421.1.201, units in domestic premises must be enclosed in non-combustible material when installed indoors. Plastic units are only permitted if housed inside a fully non-combustible cabinet that meets fire resistance standards.

    Should I use RCBOs or RCDs?

    RCBOs offer individual circuit protection, meaning one fault won’t take out all your power. They are now preferred for most modern installs.

    What unit should I install in my garage?

    Use a garage consumer unit – a compact, self-contained board with RCD or RCBO, ideal for outbuildings.

    Can I install a consumer unit myself?

    No. It must be installed or certified by a qualified electrician. This work is notifiable under Part P of UK Building Regulations.

    Do I need surge protection?

    Yes — especially for homes with expensive tech or sensitive electronics. Many new installs now require SPD units by default.

    What’s the difference between Type A and Type AC RCDs?

    Type A protects against both AC and pulsating DC faults. Type AC only covers AC faults — making them less suitable for modern homes.

    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.
