Intend to buy a detached house - has gasboiler in shed/hut just next to ourside wall, access via a door to the hut (size just enough for a boiler, overall height around 1.5 m), vent/flue just just out above the roof of the boiler hut). There is about 2 m space between house wall and fence to neighbour. Am not sure if this is covered by regulations, my surveyor was not clear about this either (???!!!), any suggestions, who do I check with? Council? or is it OK in any case, tks in advance
