I seem to have loads of beetles ( I think they are called `slaters`)

Since a 'pond slater' looks like a woodlouse, do you mean woodlice?
little grey armour plated things, about 1cm long and 1/8 inch wide?

in every
corner of the garden, under rubbish bricks etc. Are these beetles a problem ?Do
they cause damage to plants? and / or wood in houses? How do I get rid of them
( I am currently clearing rubbish etc,but I presume they will find a new
habitat in my garden)

You won't get rid of them. And there are a lot more beetles, creepy
crawlies etc that you haven't even noticed ;-)
So don't worry about them.

Most things go for soft decaying plants rather than vigorous growing
ones, and therefore perform a useful job in the garden.
