Due to several changes to regulations and advances in protective device technology, it will sometimes be advised that you upgrade your consumer unit to comply with current regulations. This will reduce the risk of potentially dangerous faults going undetected. Occasionally there are undetected faults on these 'old' circuits which will cause the new protective devices to trip. At Amounderness Electrical we will always carry out inspection and testing prior to a consumer unit change, so these faults don't come as a surprise to both you and us. Ensuring all necessary work can be agreed beforehand leaving your installation compliant and safe.
