Consumer Unit Upgrades
Replace Your Old Fuse Box with a Modern Consumer Unit
Older fuse boxes can struggle to meet the electrical demands of modern homes. If your property still has an outdated fuse board, a modern consumer upgrade can significantly improve electrical safety, reliability and compliance with the latest wiring regulations.
At LS Electrical, we provide professional consumer unit upgrades across Surrey, Hampshire and Berkshire. Whether you’re renovating your home, have recently purchased an older property or your electrical installation has been highlighted during an Electrical Installation Condition Report (EICR), our NICEIC Approved electricians can advise whether a replacement consumer unit is recommended.
What is a Consumer Unit?
A consumer unit, sometimes referred to as a fuse box or fuse board, is the main electrical distribution point within your property. It protects each electrical circuit against overloads and electrical faults while allowing power to be safely distributed throughout your home.
Modern consumer units incorporate advanced safety devices including:
- RCBO protection
- RCD protection
- Surge Protection Devices (SPDs)
- Clearly labelled individual circuits
- Improved fault protection
Compared with older fuse boxes that rely on rewireable fuses or ageing circuit breakers, modern consumer units offer significantly greater protection for your family and your property.
Signs You Need a Consumer Unit May Need Replacing
Many homeowners don’t realise their consumer unit is outdated until electrical problems begin to occur.
You may benefit from a consumer unit upgrade if:
– Your fuse box still uses rewireable fuses
– Circuits regularly trip
– You have no RCD protection
– Your property is being extended or renovated

If you’re unsure whether your existing installation is suitable, LS Electrical can carry out a professional inspection and advise on the most appropriate solution.

Frequently Asked Questions
How do I know if my consumer unit needs replacing?
If your fuse box still uses rewireable fuses, lacks RCD protection or has been identified during an Electrical Installation Condition Report (EICR) as requiring improvement, replacing it with a modern consumer unit is often recommended. A qualified electrician can inspect your installation and advise whether a consumer unit upgrade is necessary.
Is replacing a fuse box the same as replacing a consumer unit?
Yes. Many homeowners still refer to the electrical distribution board as a fuse box or fuse board. Modern installations are known as consumer units and provide significantly improved electrical protection through RCDs, RCBOs and surge protection devices.
Can I upgrade my consumer unit without rewiring my house?
In many cases, yes. A full rewire is not always required. Before installing a new consumer unit, your electrician will inspect the condition of the existing wiring to ensure it is suitable and safe to connect to the new installation.
Does a new consumer unit make my home safer?
Yes. Modern consumer units provide enhanced protection against electric shock, overloaded circuits and electrical faults. They include safety devices such as RCDs and RCBOs that disconnect power quickly if a fault is detected, helping to reduce the risk of electrical fires.
Do I need a new consumer unit before installing an EV charger?
Not always. During an EV charger survey, your electrician will assess whether your existing consumer unit has sufficient capacity and the appropriate protection. If necessary, a consumer unit upgrade may be recommended before installation.
