I had an emergency call out to replace a consumer unit, (used a fully 18th edition compliant board) when compiling the installation certificate your not allowed any limitations.

now i know the rest of the house does not need to conform to 18th edition standards but The house is a large house so asides from anything obviously non compliant highlighted in my testing am i expected to ensure 100% of the installation is con formative because i cant with cables being in floors wall and partitions, i also certainly wont be dropping every accessory.

Where do i stand on this?

What's an 18th compliant CU? Does that include AFDs and SPDs?

You are not required to make sure the installation in the rest of house is compliant, if you were every board swap would be a rewire for me.

You are required to ensure that all connected and energised circuits are safe. Your testing and cert will demonstrate this.

I suggest you download and read through best practice guide 1, it will help clear a lot of issues up.

100a main switch, as i am sure you are aware SPD AFD are only a required recommendation unless you can see the need for them in a domestic

you need to get readings for each circuit and ensure they are all safe to energise and safe for continued use. they don't necessarily have to comply with current regs.
 
You can’t have limitations on the board

As in you can’t ommit rcd protection for example

The remainder of the house wiring is irrelevant so long as it’s safe for continued use

If it wasn’t safe you probably wouldn’t be changing the board in the first place

Nothing,
How long have metal consumer units with a main switch been available?
How long have RCBO's been available?
I gathered that, so why call them 18th edition CUs?
