Earth Bonding Upgrades in Steyning & Horsham

Many homeowners in Steyning and the surrounding Horsham district do not realise that electrical safety depends on more than just the fuse box. Protective bonding is the process of connecting the metal pipework in your home—specifically your gas and water mains—to the main earthing terminal of your electrical installation. This creates a safe path for electricity to follow if a fault develops, which stops your taps, radiators, or boiler casing from becoming live and dangerous. At Sussex Brown Sparks, we specialise in identifying missing or undersized bonding during our safety inspections across the BN44 area.

Earthing protects you from a fault inside an appliance by providing a path for the current to go into the ground. Bonding is different; it connects the metal parts that are not meant to carry electricity—like your copper water pipes or gas mains—to the earth. This makes sure that if a fault occurs, all metalwork stays at the same potential, preventing a shock if you touch two different metal surfaces at once.

Older properties often have 4mm² or 6mm² bonding cables. Modern BS 7671 standards usually require a 10mm² cable to handle the potential fault current safely. When we upgrade your fuse board or carry out an EICR in Steyning, we check these cables. If they are too small, they could overheat during a fault, so we recommend upgrading them to the thicker 10mm² standard to keep your home safe.

If your incoming mains water or gas pipes are plastic (MDPE), you might not need main protective bonding to those specific services. However, if the plastic pipes turn back into metal once they are inside your home, or if you have a metal gas supply, bonding is usually still required. We can test your installation to confirm whether your property is correctly protected.

You can often see a green and yellow wire clamped to the pipework near your water stopcock or gas meter. If you cannot see these wires, or if they look very thin, your home might be at risk. Sussex Brown Sparks provides expert fault finding and safety checks across Steyning and Woodmancote to identify these issues before they become a hazard.

To install a new 10mm² conductor from your consumer unit to your gas or water mains, we often need to run a new cable. We take great care in Steyning’s older or historic properties to route these cables discreetly, using existing voids or neat containment to minimise any impact on your decor.
