Two questions - I know the tax position, but do I need to notify this work under the building regulations? There has been no change of use; there has just been a repair, but this has involved the rebuilding of the fireback and hearth, use of a jackhammer, and some work which clearly does need to be done competently for safety reasons.
Second question - a timber surround for a hearth? By this I don't mean some timber on the chimney breast, but the horizontal formwork surrounding the rectangular hearth block in front of the fireplace. This has been left in place and is supposed to be the final surround. Timber sounds to me like a stupid material for this - I can't recall encountering it before anywhere else as a hearth surround - but I am not sure, and maybe it's OK? After all, looked at from the top the timber just separates the non-combustible screed from the combustible carpet and floorboard. I am assuming it is at least the regulation distance from the fireplace, which I think is 500mm?
I realise I need to have a look, but am just asking for some preliminary advice!
Thanks in advance for any help with this!
