Can a registered/qualified electrician let another person who he claims is an electrician to do an electrical job in my property and self certify the electrical job when he was not supervising the friend/apparently an electrician the whole time but only in the morning telling him what has to be done and returning hours later when his friend has finished the electrical job? Also, he refuses to provide me any information if his friend is qualified and registered as a qualified electrician to do the job? Thank you.

RCD unit 65-80A. 28kw total equipment output (Ranger cooker 16kw, microwave 2500kw, fryer 2 X 3kw, electric griddle X 3kw etc although the range cooker will not all be switch on- so average total output could be 18-23kw Will I need a new Consumer unit with 100a or can my old unit just need it's fuse changing? will all the wiring needs replacing w/ a thicker ones. Will it need 16.0mm wire (to accomodate total output) if the wire touches wall/ceiling but contained in a trunk/pvc pipe? How much time/estimated cost for this work?

What's the difference between an RCD and a circuit breaker? Or are they the same thing?

Hi My contractor said he needed to remove some floor to run wires He pulled out the ENTIRE floor. Every single board in every room Surely this is not correct ? They now want to sell new floors to me

I am about to take delivery of an EV. I'm likely to be moving by the end of the year so spending circa £1k on a domestic charger will not deliver a return on the mileage I am likely to do. The car comes with its own "mobile charger" which is 7.4kw capable. I have a modern consumer unit with Schneider Isobar Acti9 125A. There is a first generation Rolec EV EVWP0020 charger already connected to the CU via a 32A breaker. I have a SMETS2 smart meter and they are all adjacent on the inside of the garage wall by the garage door where the car will be parked. What additional components (surge protection/breakers) might I need to install a 32A rated (blue) commando socket? What would be a reasonable estimate for this job?

Do I need an electrician & a plumber to have an electric shower fitted, or are there companies that will have both so I pay one price for the job, rather than get an electrician to do electrics then a plumber to do plumbing?

I would like to install more switches at two different doorways within the same large room. Ideally both switches could be used independently of each other without any conflict. Is it feasible for me to install the additional switch and make adjustments by myself or is this more for a professional electrician to complete? In either case, is it likely that I will need to repaint or plaster around the switches afterwards? Any advice on this project would be great!

How much on average would it cost to install an extraction hood. We have an existing hood (and electrical source) in place but no extraction vent?

This wasn't a cheap unit, so I'd like to get it looked at before thinking of a replacement. Would I call an electrician for this?

I want to completely remove an old electric bar heater from my bathroom wall for tiling and don't want to reconnect anything, is it safe to cut the wires, tape them and then push them back through the wall?
