Good afternoon to all!

ISO some feedback on chimney work. Getting a new roof put on the house and want to address any chimney concerns before the roof goes on.

There are two flues, one for the oil boiler and one for the fireplace. The Oil boiler flue was relined recently. The Fireplace flue was not. The fireplace is not used, and I do not intend to use it for any sort of vented combustible fuel. Maybe one day I will do unvented Gas Log.

I'm having the Chimney inspected and they are recommending a full rebuild of the chimney from the roof line up. I have attached some photos. Would like some knowledgeable feedback on whether this is overkill considering my use of the fireplace will be very limited.

TYIA!

I'll let others comment on the chimney rebuild issue (the top foot or so looks quite bad to me) - but I see your remark about "unvented gas".
Unvented is not unvented. It is vented in your room.
It adds combustion products to the air you breathe. Humidity and CO2 in the best case.

I'd not do that.
Of course the requirements for gas venting are easier to meet than for wood fire venting.
 
The chimney rebuild is more of a roof maintenance issue. If the chimney deteriorates too much it will start to leak water into the house. That and it could collapse / fall on someone although I don't think yours is at that point quite yet.

As the mortar breaks down it will absorb more rain water which after a few freeze/thaw cycles will cause further cracking of the mortar and bricks. It's a slippery slope from there.

Yea I'm aware. This would only be occasional use, not primary heat. Or maybe electric for pure ornimental aspects
Thanks
