horazontal flue terminating into neighbour garden

If you've got it in writing go for it dude

Dont MI's state 300mm from the boundary minimum

think its something like 1m might be wrong

 

[scorps]

The min. distance from next doors boundary is 600mm.A plume kit can not be used to get out of this situation,it is breaking the building regs,speak to gas safe,they are quite clear about this,but it,s a building regs issue not a safety issue

 

[Riley]

Have a suspicion it's going to be installed

building inspectors are normally dumb as far as the rules to pluming and flues goes, great on trench depth etc.

this is old now but relevant, http://www.a1gassafe.co.uk/pdf/TECHNICAL_BULLETIN_231.pdf and mentions a 2;5 metre separation distance to prevent plume annoyance issues. if the neighbour feels the plume is still a pain with a plume divertor, solicitors will get involved and you will get drawn into it and all the resultant hassle, it is not worth the hassle.

the builder is probably the sensible one in the picture, surely if it is a new build a bit of lateral thinking, boiler on another wall or vertical will save a great deal of pain in the long run.

Also the issue of access to inspect the flue,
