I very carefully measured the recess behind my fireplace to ensure that the product would fit. When it arrived the measurements were perfect - so far so good. However, for some reason the electric source was via a 'kettle' lead on the side of the unit, which made absolutely sure it would not fit. I was offered a spacer (at additional cost of course) which might or might not allow the plug to be covered, I'll only find out when I have bought this - and it's not available until February 2024 anyway. This would defeat the object of having a recess anyway, and still mean the lead would have to be located outside and to the right of the fire to get to a wall socket - thus looking terrible. It was suggested that I got a mason to cut away the stone on this expensive fireplace surround...this is without a doubt a serious design fault, and now I am stuck with it. Very dissappointed.
