Neighbour's chimney/fireplace causing me issues

As I understood it, burning wood will only produce significant amounts of carbon monoxide (CO) if insufficient oxygen is available for combustion. If there's plenty of air for the fire there won't be much if any CO. So you should definitely get a CO alarm to ensure youre not at immediate risk of being poisoned, but even if it doesn't go off, that doesnt mean there isnt a problem. The neighbour's chimney could still be leaking smoke into your house.

I would recommend, as strongly as it is possible to do, that you contact your local fire brigade and ask them to arrange for a fire safety officer to visit your property.

Apart from the fact that most people honour the advice of such a respected professional, brigades also have some legally designated powers to enforce fire safety upon your stupid neighbours.

The visit will cost you nothing and every firefighter I have known (and it's many) has said that they'd rather be called in before a disaster, not afterwards!
