Install or replace a Fusebox in Newington

County: Central London

A fusebox (also known as a consumer unit) is the home’s electrical control centre. It houses the main switch and fuses or circuit breakers that protect your circuits. Over time, older fuseboxes—especially those still using fuses rather than modern circuit breakers—can become unsafe or unreliable. You might need to install a new fusebox if your current one is outdated, damaged, or not compliant with current UK electrical safety regulations. Replacement is often advised when carrying out major electrical work or extensions. Ensuring your fusebox is modern helps prevent electrical faults and reduces fire risk, giving you peace of mind.

⭐ Introduction

You might need to install a new fusebox if your current one is outdated, damaged, or not compliant with current UK electrical safety regulations. Replacement is often advised when carrying out major electrical work or extensions. Ensuring your fusebox is modern helps prevent electrical faults and reduces fire risk, giving you peace of mind.

🔧 What the job involves

Replacing or installing a new fusebox means removing the old unit and fitting a modern consumer unit that meets the latest standards (BS 7671 UK Wiring Regulations). The electrician will:

Turn off power at the mains to make the work safe.
Disconnect the existing fusebox carefully.
Run and connect cables for the new fusebox and any additional circuits if needed.
Install modern safety devices like Residual Current Devices (RCDs) or Miniature Circuit Breakers (MCBs).
Test the new installation thoroughly to ensure everything is safe and working correctly.
Certify the work in line with Part P Building Regulations, which requires notifying your local authority or using a registered electrician.

📝 Step-by-step from booking to completion

Initial enquiry: Contact a qualified electrician to discuss your needs and arrange a site visit.
On-site survey and quote: The electrician inspects your existing fusebox and wiring, discusses options, and provides a written quote.
Booking: Agree a date for the work, ensuring minimal disruption to your home.
Day of installation:
- The electrician arrives and switches off your electricity supply safely.
- They disconnect and remove the old fusebox.
- Install and connect the new consumer unit and circuits.
- Test and commission the system.
- Clean up the work area.
Completion paperwork: Receive your Electrical Installation Certificate or Building Regulations Compliance Certificate. Keep these documents safe for insurance or resale purposes.
Aftercare advice: The electrician may offer guidance on maintenance and what to do if any electrical issues arise.

💷 Main costs to expect

Labour: Typically the biggest cost; electrician’s time including installation and testing.
Materials/parts: New consumer unit, circuit breakers, wiring accessories.
Disposal: Safe removal and disposal of your old fusebox and any redundant parts.
Certification: Cost of electrical safety certification and notifying building control if applicable.
Extras (possible):
- Additional circuits or upgrade to your electrical wiring.
- Upgrading the earthing system or adding RCD protection to all circuits.

Example cost breakdown:

Labour: £200–400
New consumer unit: £100–250
Certification and paperwork: £50–100
Disposal of old unit: £20–40

Total typical cost might range from £400 to £800, depending on complexity.

📊 What affects the price

Access: How easy it is to reach the fusebox and the existing wiring.
Complexity: Number of circuits, presence of old wiring, condition of earthing system.
Regulations: Must meet current BS 7671 standards and Part P building regs.
Remedial works: Old or damaged wiring and connections may require repair or replacement.
Location: Costs can vary regionally across the UK.
Timeline: Urgent or off-hours work may incur higher charges.

⏱ How long does it take?

Straight swap: Replacing a fusebox with a modern equivalent in the same location usually takes between 2 to 4 hours.
Complex installations: New circuits, rewiring, or relocation of the consumer unit can extend the job by additional hours or days.
Always allow extra time for testing and certification.

🏠 Can you DIY it?

Replacing a fusebox is NOT a recommended DIY job. It involves working directly with your home’s electrical supply and must comply with strict UK safety regulations including Part P Building Regulations. Incorrect installation risks electric shock, fire, or non-compliance, which could invalidate your home insurance.

Always hire a Gas Safe registered electrician or an electrician registered with a competent person scheme to carry out this work safely and legally.

💰 Typical UK price range

Most homeowners can expect to pay between £400 and £800 including VAT (where applicable) for a typical fusebox replacement. More complex installs or additional wiring work can increase the price.

Remember, this is a rough estimate. Always get multiple quotes and confirm exactly what is included.

✅ Handy tips before you start

Prepare by informing household members of the power shutdown to avoid surprises.
Clear access around your fusebox and ensure the surrounding area is tidy.
Ask for a detailed written quote including parts, labour, and certification costs.
After installation, keep all paperwork and compliance certificates safe. These documents are important for insurance and future resale.
Schedule periodic electrical inspections, typically every 5–10 years.
Report any electrical issues such as frequent trip-outs or flickering lights to your electrician promptly.

Replacing or upgrading your fusebox is an important investment in your home’s safety and efficiency. Taking the time to plan, hire a qualified professional, and keep proper documentation will ensure the job runs smoothly and to expected standards.
