Thanks. I have returned the channeling and have exchanged it for the
oval conduit. How does this affect the rating of the T&E?

It reduces it a little, but not much. Column C is the normal figure for
"clipped direct" or a cable buried directly in plaster. Using conduit
results in de-rating to the figures shown in column A. So 2.5mm T&E
drops from 27A to 23A

I looked at the URL you gave for the wiki and that's not the page I
found. I must have found a different DIY site (via google).

Thought that may be the case since our one probably answered your
question! ;-)

I read some old posts about the Aldi wall chaser. Now that people have
had time to play with them, what were your experiences?

Not tried the aldi one. I have a Sparky one, which is ok, and does a
good job of eliminating the dust. Has slightly awkward handling though.
