Consumer Unit Upgrade: When do you need one?
Consumer Unit Upgrade: When Do You Need One?
Your consumer unit, often referred to as your fuse box, is one of the most important parts of your home's electrical installation. It distributes electricity around your property and provides protection against electrical faults.
But how do you know when your consumer unit needs upgrading?
If you live in an older property, are planning electrical work, or your existing fuse box doesn't provide modern levels of protection, it may be time to have it inspected by a qualified electrician.
At Burdock Electrical Ltd, we provide professional electrical services throughout Peterborough, Cambridgeshire and Lincolnshire. As a NAPIT registered electrical contractor, we can assess your existing installation and advise you on whether a consumer unit upgrade is appropriate for your home.
What Is a Consumer Unit?
The consumer unit is the main distribution point for your property's electrical circuits. It controls and protects circuits supplying things such as sockets, lighting, cookers, showers and other electrical equipment.
Older properties may still have fuse boxes containing rewireable fuses or cartridge fuses. Modern consumer units typically use circuit breakers and additional protective devices such as RCDs or RCBOs.
These devices are designed to disconnect a circuit when a fault is detected, helping to reduce the risk of electric shock and electrical fires.
When Should You Consider a Consumer Unit Upgrade?
There isn't a specific age at which every consumer unit automatically needs replacing. However, there are several situations where an upgrade may be recommended.
1. You Have an Old-Style Fuse Box
If your property still has an older fuse box, particularly one without RCD protection, it's worth having it inspected by a qualified electrician.
An older consumer unit isn't necessarily dangerous simply because of its age, but older installations may not provide the same level of protection as a modern system.
An electrical inspection can establish the condition of the existing installation and whether an upgrade would be beneficial.
2. You're Carrying Out Electrical Work
If you're making significant changes to your electrical installation, your existing consumer unit should be assessed.
For example, you may be:
Renovating your home
Installing a new kitchen
Building an extension
Adding new sockets or lighting
Installing an electric shower
Installing an EV charger
Adding electric heating
Carrying out a complete property refurbishment
Depending on the work involved and the condition of the existing installation, your consumer unit may need upgrading or other improvements may be required.
3. Your Consumer Unit Doesn't Have RCD Protection
RCDs, or Residual Current Devices, provide additional protection against electric shock.
They monitor the electrical current and can disconnect a circuit when they detect an imbalance that could indicate current flowing somewhere it shouldn't.
If your existing fuse box doesn't provide RCD protection, it is worth discussing your options with a qualified electrician.
4. Your Consumer Unit Is Showing Signs of Damage
Never ignore signs that your consumer unit may have an electrical fault.
Warning signs can include:
Burning or scorch marks
A burning smell
Buzzing, crackling or sparking
Excessive heat
Damaged switches or covers
Fuses repeatedly blowing
Circuit breakers repeatedly tripping
If you notice burning, overheating or other signs of an electrical fault, seek professional advice promptly.
5. You're Installing an Electric Vehicle Charger
EV chargers can place a significant demand on a property's electrical installation.
Before installing an EV charger, the existing electrical installation needs to be assessed to determine whether it is suitable.
In some properties, the consumer unit may need upgrading as part of the work. Other electrical improvements may also be necessary depending on the existing installation.
6. You're Buying or Selling a Property
If you're buying an older property in Peterborough, Cambridgeshire or Lincolnshire, an electrical inspection can give you a clearer picture of the condition of the electrical installation.
Likewise, if you're preparing your property for sale, addressing known electrical issues can help avoid unexpected problems during the conveyancing or inspection process.
An old consumer unit doesn't automatically mean the property is unsafe, but it may be worth having the installation inspected by a qualified electrician.
Does an Old Consumer Unit Have to Be Replaced?
Not necessarily.
There is a common misconception that every consumer unit over a certain age must automatically be replaced. The condition of the equipment, the type of installation and the work being carried out all need to be considered.
A qualified electrician can inspect the consumer unit and associated circuits and advise whether replacement is appropriate.
If you're having alterations or additions made to your electrical installation, different requirements may apply to the work being carried out.
What Does a Consumer Unit Upgrade Involve?
A consumer unit upgrade involves replacing the existing consumer unit with a modern unit that provides appropriate protection for the property's electrical circuits.
Before and during the installation, the electrician will need to assess and test the existing circuits. If problems are discovered, additional remedial work may be required before the new consumer unit can be safely installed.
A typical installation may involve:
Isolating the electrical supply.
Removing the existing consumer unit.
Inspecting and testing the existing circuits.
Installing the new consumer unit.
Connecting and identifying the circuits.
Testing the completed installation.
Providing the appropriate electrical certification.
The exact process will depend on the property and the condition of the existing electrical installation.
How Much Does a Consumer Unit Upgrade Cost?
There isn't a single price for every consumer unit upgrade.
The cost can depend on:
The number of circuits in your property
The type of consumer unit required
The type of circuit protection used
The condition of the existing wiring
Whether faults need to be repaired
Whether additional earthing or bonding work is required
Whether other electrical work is being carried out
At Burdock Electrical Ltd, we recommend assessing the existing installation before providing a quotation. This allows us to identify any potential issues and give you a clearer idea of the work involved.
How Long Does a Consumer Unit Upgrade Take?
A straightforward consumer unit replacement may be completed within a day, although the timescale can vary depending on the property and the condition of the electrical installation.
If testing identifies faults or other remedial work is required, additional time may be needed.
Your electrician should explain the proposed work and let you know if any issues are identified during the installation.
