Hi. Thanks for that. I want to change the light switches though and don't fancy doing it on a live circuit. How can I switch off the alarm? If it is connected to the lighting circuit for its power, how does it still ring when the fuse is pulled? Is there a battery in it somewhere or is it...

Why does my burglar alarm ring when I pull the fuse out from my upstairs lighting circuit? How can I stop it doing it?

Sorry. I read it, but clearly did not digest it.

What conduit can be used to run cables outside of a safe zone? What's the best way to earth it?

By the way, do your downlighters have earth connections? As far as I can tell, mine do not. I hope that's not bad.

If an electrical appliance is run from a spur, is it better to have a fused switch or an RCD in the spur?

I'd be interested to know the answer to this one too as the downlighters in my new house (installed by previous owner) appear to have two different installations: 1) junction box to set of lights (jb - 1 - 2 - 3 - ...) 2) junction box to set of lights and then back to junction box (jb - 1 - 2...

Wonderful. Thank you.

Would they be more interested if I asked for a new boiler in a different place from the current one?

I don't mean to be rude, but does anyone have any further thoughts?

So will the loft floor gain strength (or become weaker due to the increased weight) if I run timbers (e.g. 3x2) at 90 degrees to the joists and about 2 feet apart before boarding?

Thanks for all the replies folks. Just to compare, what is a typical flow rate from a cylindr mounted on the same floor as the bath? Is it about 15-20 l/min? With combis, what is the limiting factor to its hot water provision, the temperature of the input water or the pressure in the...

Any other thoughts on how I might wire up my telly?

I don't have a digital camera at the moment (it's broken) so I can't post any pictures. What sort of further information would you require? Is there any regulation which would prevent siting a boiler in the loft or on an upper floor in a very standar (but small) 3 bed semi?

Hi. Thanks for all the replies. Just to summarise: 1) My pipework is (apparently) non barrier pipe, which (I was told by a plumber) is responsible for allowing air (oxygen) to pass into the water, thereby increasing the rate of corrosion of the system internally and causing an enhanced...

It is non-barrier pipe (so I'm told). If I get it replaced should I go for copper or barriered plastic? Which is a) quicker b) cheaper c) messier Will the new pipes be visible or hidden in the walls like the current ones? Cheers.

That's a lot of information for my small brain, but thanks. It's very helpful.

Thanks guys. Your comments are very much appreciated. I'm asking because I have a new flat screen LCD telly and want it to hang on the wall with no evidence of cables. My initial plan was to change an existing socket for a fused switch and run the TV power cable behind the plasterboard...

Thanks for the quick response. So, as I understand this link, cables can be run either horizontally or vertically to a point (but with no direction change). Cables can run from the top down or the bottom up. It doesn't mention anything about cables behind skirting boards. Does that mean...

What are the rules on burying electrical cables behind plasterboard and skirting boards? 1) Are you allowed to have cables running horizontally behind plasterboard? 2) Are you allowed to run cables at floor level behind skirting boards? 3) Are you allowed to run cables vertically from both...
