Fuse Box Upgrades Cardiff & Pontyclun | APP Electrical Ltd

At APP Electrical Ltd, we provide professional fuse box upgrades and consumer unit replacements in Cardiff, Pontyclun and across South Wales. Your fuse box is the heart of your home’s electrical system, and if it’s old, outdated, or lacking modern protection, it could be putting your property and family at risk. Many homes in South Wales still have older fuse boards with rewirable fuses, wooden backboards, or no RCD (Residual Current Device) protection at all. These systems may still function, but they don’t meet today’s safety standards and can increase the risk of electric shocks and fire.

Upgrading your consumer unit ensures your home is compliant with the latest UK wiring regulations and provides you with peace of mind that your electrics will protect you when it matters most. A new fuse box fitted by APP Electrical Ltd comes with modern circuit breakers and RCDs that disconnect the power instantly if a fault occurs, reducing the chance of serious injury or fire. It’s one of the most important safety improvements you can make to your property and is often recommended when selling or remortgaging a house, as surveyors and insurers recognise the risks of outdated units.

Homeowners typically notice problems that indicate it’s time for a replacement. If your electrics trip regularly, your fuses blow often, or you can see scorch marks or smell burning near your consumer unit, these are clear warning signs. Even if you don’t have visible issues, the absence of RCD protection is reason enough to consider an upgrade, since modern devices are designed to react instantly to faults that old fuse boards may not catch.

The cost of a fuse box upgrade in Cardiff or Pontyclun generally falls between £400–£650, depending on the size of your property, the number of circuits, and whether any additional remedial work is required. At APP Electrical Ltd, we provide free, transparent quotations with no hidden extras. Our team will carry out a full survey of your installation, explain what’s required, and give you a fixed price so you know exactly what you are paying for. All installations include full testing and certification, and you will receive an Electrical Installation Certificate (EIC) for your records.
