I have just fitted a new dual row Hager consumer unit with SPD for a client who has EV, will be getting battery and PV
Hager do a change over switch (SF263), which is NOT an isolator (you will need the isolator in the main unit as well as an isolator in the new unit for the generator supply...
I have had this recently
You need to have the heater on the 24h supply and then get the switching times for off peak from the supplier- as well as ask them if the switch times stay on GMT or change by an hour in the summer
Good luck getting this from your electricity supplier- I would also ask...
I would advise caution
The client is telling you what the job scope is- it is your job to let them know what needs to be done to make things safe and then they can decide what to do
When you go back take pictures and notes and then let them know you will send an estimate later on
You should...
Some suppliers do not charge for an isolator, maybe swap supplier to one who does not charge
There is also a scheme where the DNO will upgrade a supply for free for green stuff- and you will get a free isolator as part of the works
Yes, thats a bit naff
I think the problem is that 80% of Westminster are people who went to independent schools and these people are less in touch, in Scotland there is a left leaning government and many of them have been at the hands of dodgy landlords.
Most Scottish MSP's went to normal state...
There is not one UK building standards. Things differ across the UK
In Scotland the cladding used at Grenfel where these poor people were killed was banned in homes above 2 floors in 2006/7

The regulations prefer (and usually require) a single point of isolation. You currently have 2 consumer units with seperate isolators
The new consumer unit you have will be too small if you are adding PV etc, the max Hager do in a single row is 14 way with SPD (RCBO's), remove 4 ways if a dual...
I am in the process of quoting a new consumer unit where the client will need a larger consumer unit
She is going for a dual RCD with additional RCBO's for, I will be installing a Hager VML91620CUSPD
She is also getting PV and probably battery storage - this is the reason for the larger unit...
If you wanted to limit current in the property you could have the heavy duty appliances hard wired on to different circuits through an fused connection unit etc and have the rest of the sockets on a 10A MCB, this would allow for almost all general use and prevent things like heaters and car...
We are NOT looking to take an apprentice on, however we can give you limited work experience (depending on where you live)
There are other options- the younger apprentice route is open to any age.
You could work for a SJIB 1st year apprentice rate and progress that way, there is someone aged 50...
I was assuming the 5 cores went from the boiler (FCU) to the cyliner cupboard.
By moving the reciever for the programmer you now have s/l for CH and HW adjacent to the pump and motorised valves, the 4 cores you have will do L/N/E/SL - boiler.
The existing programmer would now be redundant
I would have the 4 cores as
L,N,E - supply to JB (install hive reciever at joint box)
4th core pump over run
The hive adjacent to the zone valves stops the need for the s/l for the CH and HW as it can now be derived from the new hive reciever (in the cylinder cupboard)
Unless I am reading it wrong there is one core short at the junction box (where the zone valves / cylinder are)
The Hive (or similar) only needs a L,N,E so the reciever can be located adjacent to the joint box. As the reciever will give you seperate switched lives for HW (on), CH (on) and even...
You could do away with the timer and install a hive reciever in the area where the zone valves are.
A 2 channel hive (or similar) would work and leave you an extra core if needed as the hive only needs a 230V supply
You would still be able to connect things to this such as remote thermostats etc.
My ex apprentice (now an excellent qualified spark) now lives in London and has his own company
Once Marconi has been I can send him a message.
I don't know if he is doing domestic work or not but I can check
Some pictures of the current aet up would help
Without taking any covers off consumer units etc can you photograph your consumer unit and meter set up and post it online?
Several would be good
Close up and from a distance
