Thank you for your simple yet helpful explanation.LadySpark wrote: ↑Mon Nov 29, 2021 5:06 am Rover some of those responses were accurate but possible a little complicated. RCBOs are better but more expensive. You don't need them. You haven't been quoted for them. The price will go up if you ask for them. Without knowing any details, I would give a very broad estimate of £500 - £1000 for a new fusebox. It isn't as simple as just googling the price on the internet because the fuse box (Consumer unit) doesn't come with the "bits inside" and you are unlikely to make the correct choices unless you know what you are doing. The quote does seem slightly high for twin RCD (which is what the quote is for), so get another couple of quotes. When you get the quotes, ask the electrician if they recommend RCBOs and to give you two quotes, one with RCBOs and one without, so that you can make a choice once you know the price and the advantage.
I forgot to mention that the RCD switch does absolutely nothing when pressed.
I have sacked the electrician off as he was due to come on Tuesday, but I've been chasing him up for 10 days to give me his electrical test report, in which he keeps making excuses.
I got another company in yesterday who has quoted £565 to replace the unit, fill them with RCBOs and provide the NICEIC certificate.
I will email them now to get a quote without RCBOs just for curiousity sakes.
