Consumer Unit Upgrade in Pontypridd

An outdated consumer unit — commonly called a fuse board or fuse box — is one of the most common electrical safety hazards in Welsh homes. Older units with rewirable fuses or early-generation MCBs do not provide the level of protection that modern households require. Our electricians replace old consumer units with new, fully compliant metal-enclosure boards featuring RCD and RCBO protection on every circuit, bringing your installation into line with the current BS EN 61439 standard in a single day in most cases.

The key safety benefit of a modern consumer unit is the protection it provides against electrical shock and fire. RCDs (residual current devices) detect tiny imbalances in the electrical current — the kind caused when current passes through a person — and cut the power in milliseconds. RCBOs combine the function of an MCB and an RCD in a single device, providing individual circuit protection so that a fault on one circuit does not knock out your whole home. This is a significant step up from older boards where a single RCD protects multiple circuits.

Beyond safety, upgrading your consumer unit is often required by home insurance providers. Many insurers will not cover homes with old-style fuse boards, or will impose conditions on cover. Mortgage lenders and property surveyors also frequently flag outdated consumer units as a condition of sale or remortgage. A consumer unit upgrade is typically a straightforward, cost-effective investment that increases both the safety and the saleability of your home.

Our electricians carry out consumer unit upgrades across South Wales, with the majority of installations completed within a single working day. All work is fully tested and a Part P Building Regulations compliance certificate is issued the same day. We carry a range of consumer unit sizes and specifications to suit properties of all types, from small flats to large family homes.
