Boiler Legislations,

Hello, My neighbour has just had his central heating boiler ugraded, The boiler is sited in his utility room, as is ours, and the steam exits between the two houses, which are divided by 2 3ft paths and fence. Over the past few days with the cold weather coming in he has had it running a lot. My concerns are that it is sending a strong jet of steam directly onto my external utility wall, with my house being the next one along on a slight gradient, the steam is hitting the utility/garage wooden fascia's and it can be felt on the face when the wind is fair. Would this cause long term damage to the brickwork or wooden eaves/fascias and are they any legislations in place to determine a safe distance.

If the plume is hitting your property, there is a good chance it will leave a wet patch. This plume is slightly acidic (reason why condensate drain is made of plastic- copper cannot be used). I wonder what long term effect would be.

I suspect the 'engineer' has not followed relevant instructions. There again I do not fit these beanz cans, only repair them

Without a long spiel about regs, guidelines and 'grey areas'- if you take your neighbour to County Court for 'nuisance' you will get it moved (on the details given).

that would be my last option, funny thing is that he told me about his new spanking top of the range boiler prior to its installation and that he would have to get it moved to the back of his house as the jet plume is so strong, Thing is, the engineer ain't moved it. He is in the middle of getting a new double garage, old garage converted into office and sunroom extension built and will be getting 5 new rads fitted, this boiler has been installed to accomodate these so once installed will the plume become weaker ?

No it won't get weaker, depending on the make of boiler there may be a deflector kit available, but basically the rules on the installation of a condenser say it must not cause a nuisance across a boundary even if it is within permitted distances.
