agreed.
Surely it entirely depends on how confident you are in the properties of
the bricks.

Exactly. Given that this is an old house with unknown bricks and assuming
that the OP doesn't want to rip off the plaster to look, the first clue
will be when the first large hole is drilled.


You've got about 50 kg horizontal force trying to pull the top ones
straight out. A single one inch number six into reasonable softwood would
do the job. But I've seen meaty frame fixings loosened in good blockwork
by variable forces. What's the telly worth! FWIW I think I would either
go for resin, or find a way of lengthening the vertical base (e.g. a
sheet of 18 mm ply).

Exactly again. I can't believe that there is a discussion over the
difference in cost of a few pounds when the equipment involved is
presumably of value high hundreds to low thousands.

Given those two scenarios, one should go for the fixing type that is most
likely to be successful and least likely to give under load. In that
respect, plug fixings and sleeve anchors are somewhat questionable if the
brick proves to be soft - they can just pull out. Equally, sleeve anchors
can split bricks when tightened and the tolerance with getting the holes
just right is not large. In addition, there is really no way to inspect
the result of drilling without cutting away the plaster.

With all of that in mind, resin fixings are the obvious choice. They are
also the most expensive, but considering the consequences of the lot
coming off of the wall, this is not something that should be bodged and
skimped.

The point I'm making is nothing to do with cost or labour involved or
anything like that. I'm just saying that my 15-year old TV bracket is rated
to carry up to and including 60Kg and it came supplied with the 6 screws and
plugs to do the job, already in the box - that's what the manufacturers of
the bracket supplied so I used them and it's worked for me.
