AFAIAC there is a 600mm minimum clearance required to the boundary, sot he boiler is non compliant, assuming fitted after the relevant date (which I cant recall or be bovvered to check).
Normally the difficult issue is spoiling neighborly relations, but in this case there is no real issue. Try to get the LL to change the boiler. H e may be able to run a flue extension so the terminal is in an appropriate position. You may wish to point out that when he sells the house he has to declare any neighbour disputes
