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 £100 + 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 £200 + VAT (double our standard carriage-paid order value of £100 + 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 £100 + VAT:
Orders above £100 + 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 £200 + 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 £200 + 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.

Supplier Lead Time & Availability

This item may be sourced from our supplier before dispatch.
The lead time shown is an estimate only and is based on the usual supplier timeframe. It is subject to supplier availability and is not a guaranteed delivery date.
We do not have a live supplier stock feed, so supplier stock can change without notice.
Delivery timers and courier estimates apply once the item is available for dispatch.
If the item is unavailable, we will contact you with the available options, including waiting for stock, choosing an alternative product, cancellation, or a refund for the unavailable item.
This does not affect your statutory rights.
