What is a consumer unit?
A consumer unit, often called a fuse box, is the central point that controls and distributes electricity in your home. It contains protective devices like circuit breakers or RCDs that shut off power if there’s a fault. Birmingham electricians in the Sunrise network install and upgrade consumer units to meet the latest regulations — keeping your property safe and compliant.
When should a fuse box be upgraded?
Common signs include an outdated fuse board with rewireable fuses, lack of RCD protection, buzzing noises, or regular tripping. If your property hasn’t been checked in years, or you’re carrying out a rewire or major renovation, it’s the perfect time to upgrade. Sunrise electricians across Birmingham will assess your current unit and advise if a replacement is needed.
What’s included in a consumer unit upgrade?
The process involves removing the old fuse board, fitting a new consumer unit with modern protection devices (like RCBOs), testing the circuits, and issuing certification. Birmingham electricians also check bonding and earthing arrangements. The job usually takes a few hours, depending on the size of the installation, and includes a full Electrical Installation Certificate (EIC) on completion.
What’s the difference between RCD and RCBO?
An RCD (Residual Current Device) protects against electric shock by cutting power if it detects leakage. An RCBO (Residual Current Breaker with Overcurrent) combines RCD protection with circuit breaker functionality — offering better safety and less inconvenience if a single circuit trips. Most new consumer units now use RCBOs as standard, and Birmingham electricians will recommend the best setup for your needs.
Is a fuse box upgrade a legal requirement?
There’s no blanket law requiring replacement, but your property must meet current safety standards if rented or undergoing major work. If your existing unit lacks RCD protection or is in poor condition, a replacement is strongly advised. Birmingham electricians ensure your consumer unit complies with BS 7671 wiring regulations and provide documentation for landlords, insurers, and building control where needed.
Can I upgrade my consumer unit myself?
No — this is not a DIY job. Fuse box upgrades must be carried out by a qualified, registered electrician. It’s a notifiable job under Part P of the Building Regulations and must be certified. Birmingham-based Sunrise electricians are fully accredited and able to handle the work legally, safely, and efficiently — giving you peace of mind and full paperwork.
How much does it cost to upgrade a consumer unit?
Prices vary depending on the size of the installation and your property layout, but in Birmingham, a standard domestic upgrade typically starts from a few hundred pounds. Sunrise electricians offer clear quotes and will explain exactly what’s included. It’s a worthwhile investment that improves safety, reduces future maintenance, and helps meet legal obligations for landlords or sellers.
Will I need to rewire the whole house too?
Not necessarily. If your wiring is in good condition, you can upgrade the consumer unit alone. Birmingham electricians will carry out initial tests to confirm compatibility and highlight any issues. If the wiring is outdated or unsafe, they’ll recommend a full or partial rewire — but only if necessary. Each job is tailored to your property’s actual condition.
