Evening all,

I don't normally get involved with new builds as I find builders can be a bit of a nightmare....

I've just been approached by a property developer who I know quite well, and wants me a produce a specification and quote for the electrical side of things.

Just want to make sure I'm up to speed on the building regs - I'll stick my head in the docs this weekend but can anyone give me an idea of what I need to include to ensure I comply with part L and F? I've done a search but want to make sure I'm running up to date......

Extractor fans in each room that has a water supply (ok, there is more to it than that, but it's close.)
'Energy efficient' light fittings (?) for 75% of luminaires. Nothing over 150w for controlled outside lights.

Nothing over 150w for controlled outside lights

That's uncontrolled isn't it Alan?

Well, depends how you look at it!
But , yes, PIR controlled have to be 150 or less.

I'm still not sure about that Alan, I thought if they were on a pir or timer you could use what you like? Surely it's uncontrolled ones they're bothered about as they could be left on indefinitely.

Dave.

I dont think so , from the IEE guide to Building Regs:
Fixed external lighting... must be either:
a, automatic controlled to switch off in daytime, and switch off when not needed (people not detected) ,and have a maximum lamp capacity of 150W
b. energy efficient (exceeding 40 lumens per circuit watt)

I was pulled up on this on my last assessment, I'd fitted a new outside light which had 2 x120W floodlight style bulbs in it. The Assessor told me I'd done wrong, but said what can you do if the stores are still selling these lights?

And was it pir controlled Alan?

It was one fitting with 2 x 120W lamps in it, so didnt comply.

But was it pir controlled?

Yes, PIR controlled.

were wiring a property that plans were sumited in 2005, do we need to wire smokes in most rooms, all lights to be fire rated, 17th edition? IT was 1st fixed years ago and we have been appointed to finish the electric works,

advice?
