What about fire alarm, emergency lighting as its 5 stories what are the council saying should be done as some HMO's require a sprinkler system?

Alarm is straight forward LD2 in communal area and grade A in rooms. It's a standard for the area, it's based on LACORS mixed system, works very well. Emergency lighting they are not specific as long as it complies with BS5266-1:2016
This is the easy bit of the project as it's clearly defined.

some of the options I would be looking at would either be a pannel board, Ryefield/bemco or bus bar chamber and individual switch fuses for the distribution...all with a single point of isolation.

I'm starting to lean towards Switch fuses, I'd discounted these as I don't like using Henley blocks at the outset, I tend to think they are an after thought, but if I go Cut-out > Henley > 2 switch fuses each supplying a CU with 25mm SWA I'm covered. I can also use 63A fuse to discriminate between main fuse. This way if I need a second supply in the future I just remove the Henley and go direct to second Switched fuse

I wouldn't use Henley blocks...I would use a bus bar chamber.

That looks much better than Henley blocks. I'm gonna call Wylex and Hager on Tuesday to see what options they have.

Much the best way....with a bit of trunking, if needed.

Have you confirmed what fuse is in the carrier or are you assuming 100A because of the carrier? I was told they dont use 100A fuses anymore.

They will probably be expensive. Proteus will be cheaper and they aren't bad...not like their DB's.

I had a new cut out installed and asked for 100A which he was happy to do. The guy I had was really helpful, also installed new 25mm tail to meter.

I'm not a fan of Proteus, I prefer Hager, Wylex and MK. But I say that not from experience, but more snobbery........

I rate MEM/Eaton for switchgear...but they wont be as cheap as Protearse, either.

Give customer the options and relative costs that go with each options. Explain pros and cons in layman terms.
