Your local electricians in St Mellons
St Mellons combines estates built mostly in the 1980s and 1990s with the much older village of Old St Mellons, and a large business park full of offices and contact centres. Each brings different electrical needs, from tripping RCDs in family homes to critical power in commercial buildings.
We handle all of them. For businesses we prioritise IT, security and emergency lighting, and for homes we find the fault fast and get the power back on safely.

What to do in the first few minutes, while a qualified electrician is on the way to you.
If it is safe to reach and your hands are dry, turn off the main switch on your consumer unit. That cuts power to the whole property.
Keep away from sockets, switches or cables that are sparking, hot, buzzing or wet. Never try to fix them yourself.
If one circuit keeps tripping, unplug the appliances on it. A faulty kettle, heater or washing machine is often the cause.
If the whole street is dark it is a network fault. Call 105 to report it to the network operator. If it is only you, call us.
If you see smoke or flames, leave the property straight away and call 999. Do not go back in. Call us once everyone is safe.
Tell us what you can see, hear or smell. We will talk you through staying safe and give you an honest arrival time.

Warning signs
Switch off at the main switch if it is safe to do so, keep clear, and call us straight away. Damage like this is exactly what we are called out to fix.
