A Complete Guide for Bishop’s Stortford Homeowners.
Modern homes use more electricity than ever before — from smart technology and electric vehicles to increasingly powerful home appliances. Yet behind all this convenience lies a crucial layer of protection that many homeowners in Bishop’s Stortford overlook: RCDs and RCBOs. Understanding what these devices are — and why they matter — is key to keeping your home, your family, and your future safe.
This guide explains everything you need to know about RCD and RCBO protection, why it’s essential, and how to make sure your Bishop’s Stortford home is properly safeguarded.
What Is an RCD?
An RCD (Residual Current Device) is a life-saving safety device. It constantly monitors the electric current flowing through a circuit and instantly cuts the power if it detects any imbalance.
RCDs protect against:
- Electric shocks from live wires or faulty appliances
- Electrical fires caused by leakage currents
- Damage to property and equipment from earth faults
When a fault is detected, an RCD can disconnect power in as little as 30 milliseconds — fast enough to prevent serious injury or death.
What Is an RCBO?
An RCBO (Residual Current Breaker with Overcurrent) combines two critical safety functions into one device:
- RCD protection: Against earth leakage and electric shocks
- Overcurrent protection: Against overloads and short circuits (what MCBs traditionally handled)
An RCBO provides individual protection for each circuit. This means that if a fault occurs on one circuit (e.g., a kitchen socket), it doesn’t affect the rest of the house. Modern consumer units in Bishop’s Stortford homes increasingly use full RCBO setups for maximum safety and convenience.
Why RCD and RCBO Protection Is So Important
Without proper protection, even a minor electrical fault can cause catastrophic damage. Here’s why every Bishop’s Stortford home needs RCDs and RCBOs:
1. Life-Saving Shock Protection
RCDs dramatically reduce the risk of fatal electric shocks. This is especially vital in high-risk areas like kitchens, bathrooms, and gardens.
2. Fire Prevention
Electrical faults are one of the leading causes of house fires in the UK. RCBOs cut power instantly when overloads or faults are detected, helping prevent overheating and fires.
3. Compliance with Modern Standards
The latest UK Wiring Regulations (BS7671) require RCD protection on most circuits. Without it, your home could fail inspections or put you at risk with insurers.
4. Increased Reliability
Using RCBOs means that faults on one circuit don’t bring down the entire system. If one circuit trips, others remain live, making everyday life much more convenient.
How to Check if Your Home in Bishop’s Stortford Has Proper RCD and RCBO Protection
Take a look inside your consumer unit (fuse board):
- Do you see a "Test" button? That’s a sign of RCD or RCBO protection.
- Is each circuit individually protected and clearly labelled?
- Does the fuse board look modern, clean, and professionally installed?
If your board has old-style fuse wire, or if you can't see clear RCD/RCBO protection, it’s time to consider an upgrade. At JJB Electrical, we offer free visual inspections across Bishop’s Stortford to assess your current setup.
Risks of Not Having RCD and RCBO Protection
Without RCDs and RCBOs, homes in Bishop’s Stortford are exposed to serious risks:
- Electric shocks: Especially dangerous for children, pets, and the elderly
- Electrical fires: Caused by unnoticed earth faults or overloading
- Invalid insurance claims: Insurers increasingly expect modern protection
- Higher property sale difficulties: Buyers now expect certified, safe electrics
It’s not just about regulations — it’s about protecting everything that matters.
Upgrading Your Consumer Unit: What’s Involved?
Upgrading to a modern consumer unit with RCD and RCBO protection is a straightforward process. Here’s how we handle it at JJB Electrical:
- Step 1: Home Survey. We assess your current wiring, circuits, and electrical needs.
- Step 2: Quotation and Planning. You receive a clear, detailed quotation with no hidden extras.
- Step 3: Installation. Your old consumer unit is safely removed, and the new one installed and fully tested.
- Step 4: Full Testing and Certification. Every circuit is tested to BS7671 standards, and you’ll receive an Electrical Installation Certificate (EIC) and Building Control notification.
The work typically takes around one day, with minimal disruption to your home.
FAQs About RCDs and RCBOs
Q: Can I just add RCD protection to my existing board?
A: Sometimes, yes — but often it’s safer and more effective to replace the entire unit to meet modern standards properly.
Q: Do RCDs ever fail?
A: Rarely, but like any device, they should be tested regularly. Press the test button quarterly to check functionality.
Q: Is a full RCBO setup better than split RCDs?
A: Yes. Full RCBO systems provide better fault isolation and minimise disruption if a fault occurs.
Q: How much does a consumer unit upgrade cost in Bishop’s Stortford?
A: Typically between £750 to £1,200, depending on your property size, number of circuits, and specific protection needed.
