Why Upgrade a Fuse Box or Circuit Breaker?
Old fuse boxes were not designed to cope with the energy demands of modern living. If you’re relying on a system that was installed decades ago, it’s not just inefficient; it could be dangerous.
Signs You Need a Fusebox Upgrade:
- Flickering lights or frequent electrical surges.
- Fuses blowing regularly.
- Use of extension cords or multiple plug strips.
- No residual current device (RCD) for added protection.
- Buzzing or burning smells near the panel.
- Outdated rewirable fuses or wooden backboards.
Upgrading your system ensures your property is safer and more energy-efficient.

Frequently Asked Questions ?
What are the signs that I need a fuse box upgrade?
You may need a fuse box upgrade if you experience:
- Frequent fuse blowouts or tripping circuits.
- Flickering lights or power surges.
- Lack of modern safety devices like RCDs (residual current devices).
- Over-reliance on multi-plug adapters or extension leads
- Electrical burning smells near the consumer unit
- Your fuse box uses rewirable fuses instead of breakers
These signs indicate that your system might be outdated or overloaded. Consider upgrading your fuse box for improved safety and performance.
How much does a fusebox or circuit breaker upgrade cost?
One of the most common queries we receive is: “What’s the cost to upgrade the fuse box to a circuit breaker?”
The fuse box upgrade cost or circuit breaker upgrade cost depends on various factors:
- The size of your property.
- The number of circuits.
- Accessibility of your current setup.
- Whether rewiring is needed
- Type of consumer unit (standard or dual RCD, high-integrity)
Typical Costs (Estimates):
- Basic Fuse Box Upgrades: £450 – £600
- Upgrade Circuit Breaker Panels: £600 – £1,200
- Upgrade Fuse Box to Circuit Breaker (with RCDs): £700 – £1,400
- Full Rewiring (if required): Priced separately upon inspection
We always recommend an on-site inspection before providing a final quote.
What is included in a standard fusebox and circuit breaker upgrade?
Here’s what our full fusebox upgrade service includes:
- Site inspection and safety check.
- Removal of the old fuse box.
- Installation of a new consumer unit.
- Integration of MCBs and RCDs for protection.
- Full testing of all circuits.
- Certification and Part P compliance notification.
We also perform any necessary circuit breaker upgrades, rewiring, or troubleshooting.
What’s the difference between fuse boxes and circuit breakers?
1. Fuse boxes use a wire that melts and disconnects the power when overloaded. These must be replaced manually in the event of a fault.
2. Circuit breakers, on the other hand, trip off automatically and can be reset with a simple switch.
That’s why many clients opt to upgrade fuse boxes to circuit breakers.
How long does it take to complete a fusebox upgrade?
Most fuse box upgrades or circuit breaker panel upgrades are completed within 4 to 8 hours. It depends on:
- The number of circuits.
- The condition of the existing wiring.
- Accessibility of the installation area.
Larger or more complex upgrades may take longer, especially if additional repairs or rewiring is needed.
Will my power be out during the fuse box upgrade?
Yes, during the installation, your power supply will be temporarily switched off for safety. We always notify clients in advance and work efficiently to minimise downtime. You will be back up and running the same day in most cases.
Will I receive a certificate after the upgrade?
Absolutely. After completing your fusebox and circuit breaker upgrade, we will issue an Electrical Installation Certificate (EIC). This certifies that the work complies with Part P of the Building Regulations and the British Standard for Electrical Installations (BS7671).
You may need this certificate for insurance purposes, property sales, or landlord compliance.
