Hello
We had our cavity wall insulated about 2 years ago and because we had a back boiler then we had to have a vent fitted through the external wall for carbon monoxide reasons. However we have now had the boiler removed and a condenser fitted. Do we still need this vent or can it be blocked up?
Sorry if I've posted this in the wrong section.
Thanks
Phil
