Consumer Unit Replacement Cost: How Much Is a New Fuse Board?

Consumer unit replacement cost is one of the first things homeowners want to understand when upgrading an old fuse board.

Quick answer: how much does consumer unit replacement cost?

Consumer unit replacement cost usually starts from around £750 with JTI Electrical, but the final price can vary depending on the property, the existing installation and whether any extra electrical work is needed.

A straightforward fuse board replacement may be fairly simple, but the cost can increase if the consumer unit needs moving, if older wiring needs attention, or if extra safety upgrades are required before the new board can be installed correctly.

What Can Change the Price of a Consumer Unit Replacement?

The cost of a consumer unit replacement can vary because every property is different. Some fuse board upgrades are straightforward, while others need extra electrical work before the new consumer unit can be safely installed.

Number of circuits

The more circuits a property has, the more testing, labelling and protective devices may be needed. A larger home or property with more electrical circuits can take longer to complete than a smaller installation.

Condition of the existing wiring

Older wiring may need checking carefully before a new consumer unit is connected. If faults are found during testing, repairs may be needed before the work can be completed safely.

Location of the fuse board

If the existing fuse board is in an awkward or hard-to-access position, the work may take longer. Access, working space and cable routes can all affect the final price.

Moving the consumer unit

Moving a consumer unit to a different location usually involves extra cabling, labour and testing. This is one of the main reasons a replacement can cost more than a straightforward swap.

Earthing and bonding upgrades

Some older properties may need earthing or bonding improvements before a new consumer unit is installed. This helps make sure the electrical installation is safe and suitable.

Testing and certification

A proper consumer unit replacement includes electrical testing and certification. This is an important part of the job and helps confirm that the installation has been checked correctly.

Need a clearer idea of the cost? A basic consumer unit replacement may start from around £750 with JTI Electrical, but the final quote depends on what is already in place and whether extra work is needed. If you are unsure, contact JTI Electrical and we can talk you through what may affect the price before arranging a quote.

Before and After Consumer Unit Replacement Examples

Before and after photos can help show why consumer unit replacement costs are not always the same from one property to another. The condition of the existing setup, access to the board and the amount of tidying or remedial work needed can all affect the final quote.

Example 1: Upgraded to a new consumer unit

Exposed wiring before consumer unit replacement in Leicester
Before: exposed wiring before the new consumer unit was fitted.
New consumer unit fitted after exposed wiring upgrade in Leicester
After: new consumer unit installed with circuits organised and protected.

This type of work shows why a proper inspection is important. The final consumer unit replacement cost depends on what is already in place and whether the existing wiring needs attention before the new board can be installed safely.

Example 2: Older board replaced with a new unit

Old consumer unit before replacement in Leicester property
Before: older consumer unit setup before replacement.
New fuse board installed after consumer unit replacement in Leicester
After: modern consumer unit fitted neatly inside the existing cupboard space.

Some replacements are more straightforward than others, especially when the existing location can still be used. If the fuse board needs moving or extra wiring work is required, the cost may increase.

What Is Included in a Consumer Unit Replacement?

A consumer unit replacement is not just swapping one box for another. A safe installation includes checking, testing and certification so the new fuse board is suitable for the property.

Removing the old fuse board

The existing fuse board or consumer unit is safely disconnected and removed before the new unit is installed.

Installing the new consumer unit

A modern consumer unit is fitted to provide improved protection and a cleaner, safer setup for the electrical circuits in the property.

Circuit identification and labelling

Circuits are identified and labelled clearly so it is easier to understand which part of the property each circuit controls.

Electrical testing

Testing is carried out to check the condition of the circuits and make sure the installation is safe before the work is completed.

Certification

After the work is completed, the correct electrical certification is provided to confirm the installation has been tested.

Advice on any issues found

If any faults or safety concerns are found during testing, these can be explained clearly so you understand what needs attention.

Good to know: proper testing and certification are an important part of consumer unit replacement. This is one reason prices can vary between electricians and why the cheapest quote may not always include the same level of work.

Can You Replace a Consumer Unit Without Rewiring?

In many cases, a consumer unit can be replaced without a full rewire. However, the existing wiring must be checked first to make sure it is safe and suitable for the new fuse board.

A consumer unit replacement does not automatically mean the whole property needs rewiring. If the existing wiring is in good condition and passes the required safety checks, a new consumer unit can often be installed without replacing all the cables.

If faults are found during testing, these may need to be repaired before the new consumer unit can be connected safely. This is one of the reasons the final consumer unit replacement cost can vary from one property to another.

Older homes, previous DIY electrical work, damaged cables or poor earthing can all lead to extra work being needed. A proper inspection helps identify these issues before the job begins.

Simple answer

Yes, you can often replace a consumer unit without a full rewire, but the wiring must be tested first. If faults are found, they may need fixing before the new board is installed.

How Long Does It Take to Replace a Consumer Unit?

A straightforward consumer unit replacement is often completed within a day, but the exact time depends on the property, the existing wiring and whether any faults are found during testing.

Typical timescale

Many consumer unit replacements can be completed in one working day, but more complex jobs may take longer if extra wiring, fault finding or remedial work is needed.

Before a new fuse board is installed, the existing circuits need to be checked. This helps make sure the installation is safe and suitable for the new consumer unit.

If the electrician finds damaged wiring, poor earthing, circuit faults or previous unsafe electrical work, these issues may need to be dealt with before the job can be completed. This can affect both the timescale and the final consumer unit replacement cost.

If the consumer unit is being moved to a new location, the work can also take longer because extra cabling and testing may be required.

How to Choose an Electrician for a Consumer Unit Replacement

Consumer unit replacement is safety-critical work, so it is worth checking a few basics before choosing an electrician.

  • Check recent Google reviews to see what other customers say about their work.
  • Use a qualified electrician who can test the installation and provide the correct certification.
  • Ask what is included so you know whether testing, labelling and certification are part of the quote.
  • Look for local experience, especially with older properties or similar fuse board replacements.
  • Compare quotes carefully and avoid choosing on price alone if the details are unclear.

Will I Need a New Consumer Unit Before Installing an EV Charger?

Not always. Many homes already have a consumer unit that’s suitable for an EV charger installation. However, if your fuse board is older, has no spare capacity, or doesn’t meet current safety standards, your electrician may recommend upgrading it before installing your charger.

A qualified electrician will inspect your existing electrical installation and advise whether a consumer unit replacement is necessary. In many cases, it can be completed at the same time as your EV charger installation, ensuring your system is safe, compliant and ready for future electrical demand.

If you’re planning to install a home charger, it’s also worth reading our guide: 5 Questions to Ask Before Hiring an EV Charger Installer in Leicester . It explains what to ask before choosing an installer, including electrical assessments, OZEV approval, certification and warranties.

Consumer Unit Replacement Cost FAQs

Here are some common questions homeowners ask when comparing consumer unit replacement costs and planning a new fuse board installation.

  • How much would an electrician charge to replace a consumer unit?

    The cost to replace a consumer unit can vary depending on the size of the property, the number of circuits and the condition of the existing wiring. With JTI Electrical, consumer unit replacement usually starts from around £750, but a proper quote is needed to confirm the final price.

  • Can you put in a new consumer unit with old wiring?

    Yes, in many cases a new consumer unit can be fitted with existing wiring, but the wiring must be tested first. If faults, damage or safety issues are found, repairs may be needed before the new consumer unit can be connected safely.

  • How long does it take an electrician to replace a consumer unit?

    A straightforward consumer unit replacement is often completed within one working day. More complex jobs can take longer if the fuse board needs moving, if faults are found during testing or if extra wiring work is required.

  • Is it illegal to replace your own consumer unit?

    Consumer unit replacement is not a DIY job. It involves electrical safety testing, certification and compliance with building regulations. For safety and legal reasons, it should be carried out by a qualified electrician.

  • Is a new consumer unit a full rewire?

    No, a new consumer unit is not the same as a full rewire. In many properties, the consumer unit can be replaced without rewiring the whole home. However, the existing wiring must be tested and any faults may need repairing before the new board is fitted.

  • Can you sell a house with an old fuse box in the UK?

    You can usually sell a house with an old fuse box, but it may raise questions during surveys or electrical checks. An older fuse board may concern buyers, especially if it lacks modern safety protection. Replacing it can make the property feel safer and more up to date.

  • What are the signs of a faulty consumer unit?

    Warning signs can include frequent tripping, buzzing sounds, burning smells, heat marks, damaged switches or an old fuse board with limited protection. If you notice any of these signs, arrange for an electrician to inspect it.

  • Can you get a new fuse box without rewiring?

    Yes, you can often get a new fuse box without a full rewire, provided the existing wiring is safe and passes the required checks. If faults are found, those issues may need to be fixed before the replacement is completed.

  • How often should a consumer unit be replaced?

    There is no fixed replacement date for every consumer unit, but older fuse boards may need upgrading if they no longer provide suitable protection or if they fail safety checks. An electrician can inspect the unit and advise whether replacement is recommended.
