Fuse Box Repairs in Blackpool

Your consumer unit (fuse box) is the nerve centre of your home's electrical system. When components fail — whether it's a blown fuse, a faulty MCB, a failed RCD or a damaged enclosure — it needs prompt attention from a qualified electrician. ESI Electrical repairs and replaces consumer unit components across Blackpool and Lancashire.

MCB & RCD Replacement in Blackpool

Individual MCBs (Miniature Circuit Breakers) and RCDs (Residual Current Devices) can fail over time, particularly in older consumer units. A failed MCB may refuse to reset after tripping, or may trip immediately when reset. A failed RCD may not trip when tested, or may trip randomly without a fault present. We replace faulty MCBs and RCDs with compatible units, restoring correct protection to your circuits.

Consumer Unit Enclosure Damage

Damaged consumer unit enclosures — cracked covers, broken doors or burnt plastic — are a fire and shock risk. Since 2016, all domestic consumer units must be housed in non-combustible (metal) enclosures. If your plastic consumer unit is damaged, we'll assess whether it can be repaired or whether a full replacement is the safer and more cost-effective option.

When Repair Becomes Replacement

Sometimes the most cost-effective solution is a full consumer unit replacement rather than repairing an old unit. If your board is over 25 years old, uses rewirable fuses, lacks RCD protection or has multiple failing components, a replacement is likely the better investment. We'll give you an honest assessment and a clear quote for both options.
