Advice for installing concrete lintel for chimney breast removal

[Salman T]

Hi, we're making our chimney hole bigger to insert a cupboard inside.
We're keeping the adjacent support walls and installing a lintel to lift the arch higher (see picture attached).


I've had to also fill in the gaps between lintel and bricks with slates (as gap was too wide). I'm told this is a sound approach. Any second opinions on this?
Please see pictures attached and comment.


Thanks.
