The previous occupant of my house (1990s-built) installed power in the loft to run a few lights and a double socket for a TV signal booster plus external security lights.
The power source is a spur from an immersion heater switch in the airing cupboard, via a fused connection unit in the airing cupboard; there's then another FCU in the loft before the cable runs to the light switch and power socket. All cable is standard 2.5mm.
The immersion heater is run from a 16A circuit; there's nothing else connected to this circuit. The immersion heater is rarely used.

It all looks like a decent job to me, but I just want to check the wisdom/safety of taking the spur from the immersion heater circuit - is this okay, or should it be a spur from an ordinary ring circuit (which my fusebox tells me is rated at 32A)?
Also, what fuses should I put in the FCUs?

the loft should be on the LOAD side of the cupboard fcu

fuse size depends on what you are going to connect to fcu
 
Thanks breezer

Yep, just checked - loft is on the load side of the cupboard FCU.
So is it okay for the spur to come from the immersion heater switch?

I'll be running a TV signal booster and a couple of 500W external security lights wired via a junction box into a standard 3-pin plug, into the existing socket.
Plus 4x60W lightbulbs when I'm up there (don't like dark spaces!)
 
i would opt for flourescent lights, brighter and more even light

Fair enough ... but what about the fuse rating for the FCU serving 4x60W bulbs, a TV signal booster and a couple of 500W security lights?
 
yeah a 5A for the security lights

and a seperate 3A for everything else
