It is on an internal shared wall, were looking at moving a rad on this wall as it's going to be the only open wall available, not sure if there will be any issue with an airbrick behind this rad though ??

Hi hope this is the correct section, we are in the process of redecorating an upper bedroom and looking at closing the fireplace up, i realise a closed one should be vented for air circulation but downstairs we have a gas fire in the living room and a gas open basket in the dinning room all, so, to my mind it's got ventilation, or do i still need to ventilate upstairs, many thanks
