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?

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.

Thank you andy i will check this guide
Am I glad I am out of the loop on this industry
 
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

It's got a big 18 sticker over the 17th one Pete.
So what is the difference?

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?

If they have an spd I guess we could start calling them 18th Ed compliant ...?
 
So sparkys can charge customers more than the charged whoever recommended them. Because the board they are fitting is up to 18th edition . it makes customers feel good knowing they have bought the latest kit .

There's your answer Pete.

I would say mainly marketing, but some have made changes. For instance Hager's consumer units marked up "18th" now come with 100A RCDs as standard instead of 63A and 80A options, the RCDs are type A not type AC, and some include SPDs.

You need to be able to operate the fuse board in the event a horse crashes through the house and attempts to chew on it.
So it needs to be horse proof... can’t believe you didn’t know that
 
18th is metal, not plastic
