Hi my next door neighbour has had a new boiler fitted this week. The plume from the boiler is setting off my outside light. It’s blowing up against my property and it comes in my bathroom window and bedroom window when they are open. The condensate has been run down the wall in the alley for a length of 15ft into a soil pipe. There is no insulation on the condensate either through the wall or along the pipe. My questions are Can I request my neighbour to change the flue for a vertical one? If they won’t do it can I get GasSafe to come and check their installation because I don’t think it’s been done to regulation as there is no insulation on the condensate pipe. I have picture and video but can’t seem to insert them here
