Permanently removing the chimney pipes

pieroabcd

Hi,
I see that some of my neighbours don't have the chimney pipes anymore, so I definitely want do be in the same lucky situation.
I prefer to permanently remove them rather than closing them, because I don't want to have any source of water leaking in the house.

I'll ask a tradesman a quote and a detailed description of the work, but what does the removal entail?
How would the space be filled? Brickwork or what else?
Do I need planning permission from the Council?
Is there anything in particular that I need to make sure of?

Thanks.

Pipes or pots?

Pots.

Any work involving chimney I think is subject to Party Wall Act unless your house is detached.

It's terraced.
I think that the neighbour is willing to do the same, but I'll surely ask him

Are you going to ventilate them? Rain can find it's way inside through the brickwork, as well as from the top.

I don't really know how this kind of work should be done, that's why I asked in this forum.
So they should be ventilated? How? From the top or from the sides or from somewhere else? 
Wouldn't water leak inside?

You can get one of these for the pots. Unused flues are better being ventilated.

That would mean capping, but I want to remove the pots instead

Unless you plan on removing the chimney breasts and stack all the way, I'd suggest leaving the pots and just capping them. Caps will stop water getting in, and the next owner might want to install a stove.

Personal opinion, but a stack without a pot looks silly on a building.

If you're dead set on removing the pots, the flaunching needs knocking off, something like slates over the flue, and new flaunching on top. You could get an air brick into the brickwork.
