We install RCBOs and RCDs depending on the load requirement. We always make sure to use the right wires for the installation of RCBOs and RCDs. As per new government law we always replace MCBs to RCBOs as it is more safe and reliable. You can call us if you want to do any RCD testing for you home to make sure you home is safe and secure. We can also install smoke alarms in your home to make sure the home is safe and secure. We link all the smoke alrams in your home to one circuit and we can replace them every 10 years.
