Frequently Asked Questions
Simple fuse box repairs such as replacing a single MCB or RCD typically cost £80–£150. A full fuse box replacement (consumer unit upgrade) costs £400–£800 depending on the size and specification. We provide free no-obligation quotes.
In most cases, yes. We carry a wide range of MCBs, RCDs, and consumer units in our vans, so same-day fuse box repairs and many replacements are possible. Call us to check availability across South Wales.
Persistent tripping is usually caused by an overloaded circuit, a faulty appliance, an earth fault in the wiring, or a failing MCB or RCD. Our electricians will diagnose the exact cause and fix it — not just reset the breaker.
If your fuse box has rewirable fuses, lacks RCD protection, is over 20 years old, or has failed an EICR inspection, replacement is strongly recommended. Modern consumer units provide significantly better protection against electric shock and fire.
Yes. Consumer unit replacement is notifiable under Building Regulations Part P. As NAPIT approved electricians, Megalec can self-certify all fuse box replacement work and provide the required compliance documentation.
Yes. We install, repair, and maintain distribution boards and consumer units for commercial properties including offices, retail units, restaurants, and industrial premises across South Wales.
A standard domestic consumer unit replacement typically takes 4–6 hours. During this time your power will be off, but we work efficiently to minimise disruption. Larger commercial distribution board replacements may take longer.
They're the same thing — "fuse box" is the common term, while "consumer unit" is the technical name. Modern consumer units use MCBs (Miniature Circuit Breakers) and RCDs (Residual Current Devices) instead of old-style rewirable fuses.
Under the 18th Edition wiring regulations (Amendment 2), surge protection devices are now required in most new consumer unit installations. We include SPDs as standard in all new consumer unit installations to ensure full compliance.
Yes. Loose connections, overloaded circuits, and failing components in an old fuse box can cause overheating and electrical fires. If your fuse box is warm to the touch, has scorch marks, or smells of burning, call us immediately.
