Hi I have been asked to fit a main switch / isolator by my client as they have no means of isolating the full installation by a single means. So I'm planing on fitting a Wylex isolator like the ones meter people fit but my question is what Cert should I be I fill out at the end a minor works or a full eic even though I'm not technically changing a consumer unit I'm just cutting the tails at the Henley block
Thanks
Thanks
