What it is
Missing RCD protection is one of the most common EICR observations. Depending on your board, we can add RCBOs to existing circuits or recommend a consumer unit replacement. Work is tested and certified.
What's included
- Assessment of the existing board
- Installation of protective devices
- Testing and certification
Who needs it
- Installations without RCD protection on sockets or bathroom circuits
- EICRs recommending additional protection
What you'll receive
Minor Works Certificate or EIC as appropriate.
How often
Once.
What the rules say
Each point is labelled so you can tell what's law, what's a British Standard, and what's good practice or comes from your lease, licence or insurer.
- Technical standardUK (BS 7671)Awaiting professional review
RCD protection in new work
BS 7671 requires additional protection by a 30 mA RCD for most socket-outlets and for cables buried in walls in new work. On an existing installation, missing RCD protection is coded by the inspector according to the risk.

Notifiable work in homes (Part P)
In England, installing a new circuit, replacing a consumer unit, or adding to or altering circuits in a special location (near a bath, shower, pool or sauna) is notifiable. A registered competent person self-certifies the work and building control is notified within 30 days; otherwise it goes through building control.

Before your appointment
- Have your latest EICR to hand: existing faults can stop new RCDs from staying on until they're fixed.
If something's found
- Each circuit is tested before the new devices are fitted. Faults that would trip them are explained and quoted first.
- The work is certified.
What affects the price
- Number of circuits
- RCBOs versus RCDs
- Whether the consumer unit has room or needs replacing
- Faults found on existing circuits
