Most circuits now require an RCD before any electrical work can be carried out and certified. HSI Electrical will check your consumer unit and if you already have protection we can add anything you like. In the event you do not have an RCD consumer unit then we can change it for you, or as an alternative we can add RCD protection to the circuit.

​Carrying out this approach ensures you are legal and safe. As an alternative we can issue you an advisory about upgrading your consumer unit at a time to suit you in the future. HSI Electrical do all types of electrical work with our most popular requests being listed on the main page.
