I have used it before. Andy found plenty of faults on the site then.

The lighting wiring bit seems both accurate and helpful. The stuff on
fuses is mainly OK, with the notable exception of the claim that
doorbells need a 5A fuse! (Possibly an 'escape' from the cart-fuse-CU
section?)

Their section on wall fixings is more questionable. They have the good
idea of segmenting advice according to what sort of wall you're fixing
to: but make no distinction in pictures or text once a fixing type is
deemed "suitable" for a given type of wall - mush more useful would be
"best for heavy", "pretty good all round", "just about suitable". And no
mention of just what a b*****r concrete is to actually drill into
without an SDS, nor how rare it would be in a domestic wall...

They did make changes to the site after Andy Wade wrote to them and
highlighted the faults. I seem to remember they had the cheek to ask him to
check all their wiring diagrams for them.

Indeed a picture is worth a thousand words (I used the same saying when I
first gave the link). It could change your text from

"OK. If you want to make the new connections "inside" the new fitting,
your job is basically to faithfully replicate the pattern of connections
inside the existing rose. So, label the wires of the existing cables
carefully. There are four, yes four, sets of cable cores which are being
connected together; so to replicate the existing interconnection you
need a 4-way section of "chocolate block" (terminal block) - if we're
talking doing the best job, try to find the sort which has little leaves
of spring metal clamping down the cable groups instead of just the bare
screw.

One way is for all the earths. One is for "all" the neutrals - if you've
just two cables as the moment, there's most likely just one black N to
which the existing pendant cable's blue core is connected, at one of the
outer of the three blocks in the ceiling rose. That's the one you
connect the N wire of the new fitting to, in the second way of the
choccie block. Next way is for all the permanent lives; again with just
two cables there should be just two of these, one in each cable,
currently connected to the middle one of the three long blocks in a line
across the middle of the rose, and each coloured red - though it's
possible that one's black instead, with or without a bit of red sleeving
or tape on it, if the switch wiring is done "the wrong way round". None
of the wires from your new fitting connects here. Final way is for the
"switched live" or "switch return" - should be just one core of one of
the cables, in the best case black with the bit of red tape/sleeving
mentioned above, if wired "the wrong way round" it'd be red instead, but
in either case currently connected to the other outer block of the rose
and where the brown core of the pendant flex is also connected; this way
is where you'll connect the L wire of the new fitting"

The FAQ should have something similar, or indeed better. This lighting
question is asked frequently.
