What We Provide

BS 7671 Compliant RCBO Installation

Our qualified electricians install RCBOs that meet current 18th Edition wiring regulations. All work is certified to Building Regulations Building Regulations standards for electrical safety in domestic properties.

Consumer Unit Assessment

We check your existing consumer unit capacity and condition before recommending RCBO upgrades. Many Swindon properties have older Wylex or MEM boards that need evaluation for compatibility.

Circuit Testing and Certification

Each upgraded circuit is tested for insulation resistance, earth continuity, and RCD operation. You receive proper electrical certificates for building control and insurance purposes.

Minimal Disruption Installation

RCBO upgrades typically take 2-3 hours per circuit. We isolate individual circuits where possible to maintain power to essential areas during work.

Signs You Need RCBO Upgrades

⚠️

Frequent RCD tripping affecting whole circuits

If your main RCD trips and kills power to half your house, RCBOs would isolate just the faulty circuit. This is particularly common in Swindon's 1980s estates where shared RCDs protect multiple circuits including lighting and sockets.

⚠️

Old rewirable fuses or early MCBs

Properties in Old Town or Railway Village often have outdated consumer units with wire fuses or basic MCBs. These offer no earth leakage protection, which RCBOs provide automatically.

⚠️

Kitchen or bathroom circuits without RCD protection

Current regulations require RCD protection for all socket outlets and bathroom circuits. Many pre-2008 installations in areas like Penhill or Pinehurst lack this essential safety feature.

⚠️

Planning electrical work or extensions

Any new circuits for extensions, EV chargers, or garden buildings require RCBO protection. Upgrading existing circuits at the same time ensures consistent protection throughout your installation.

What Happens During RCBO Installation

1

Power isolation and safety checks

We isolate the main supply and test for dead circuits before starting work. All affected circuits are identified and residents notified which areas will be without power during installation.

2

Circuit identification and labelling

Each circuit is properly identified and tested for current loading. We update consumer unit labelling to show which RCBO protects which areas - essential for future maintenance or emergency isolation.

3

RCBO fitting and connection

Old MCBs or fuses are removed and replaced with appropriately rated RCBOs. Each device combines overcurrent and earth leakage protection in a single module, typically rated at 30mA for standard domestic circuits.

4

Testing and certification

Every upgraded circuit undergoes insulation resistance testing, earth loop impedance measurement, and RCD trip time testing. Results are recorded on electrical certificates complying with BS 7671 requirements.

Preparing for Your RCBO Upgrade

Clear access to your consumer unit

Ensure we can easily access your fuse box and have at least one metre of clear space around it. Many Swindon homes have consumer units in understairs cupboards that need clearing of stored items.

Identify essential equipment on affected circuits

Make note of any equipment that needs powering down safely before we start - computers, security systems, or medical equipment. Fridges and freezers can typically cope with a few hours without power.

Plan for power outages during work

Individual circuits will be off for 30-60 minutes during RCBO installation. Consider timing if you work from home or have young children who need consistent power for equipment.

Check current consumer unit capacity

Some older boards in Swindon properties may be too small for RCBO upgrades. If you have a 6-way board but need 10+ circuits protected, a full consumer unit replacement might be more cost-effective.
