Modern consumer units for safer homes
Your consumer unit — often called a fuse box — is the heart of your property's electrical installation. A modern consumer unit helps protect you, your family and your home by quickly disconnecting faulty circuits and reducing the risk of electric shock and electrical fires.
Whether your existing consumer unit is outdated, damaged or no longer meets the demands of modern living, HJ Electrical provides a safe, compliant upgrade tailored to your property.
