We have concerns about the closeness of our boiler flue to the neighbours velux window. Conditions permitting and the window open the flue emissions are blown straight into the window and we are obviously concerned as to wether this could be potentially harmful to the individual sleeping in this room.
According to regulations we are under the impression that a flue cannot be within 2 metres below a velux window nor 600mm to the side of one and unfortunately if this is the case our flue is within those measurements, however the flue has been there many years and the velux window has just been put into the new extension.
Our gas safe registered fitter has noted a concern to gas safe who have basically told us that the will not pay a visit because it is not in their remit and have advised us to contact building control but because the neighbours have used a private building inspector the local council cannot get involved. The next step was to speak to the actual building inspector on the job but he was not interested in our concerns because the builder had told him it was not a problem. We even directed the guy to planning portal part j, pointed out by gas safe, to where there is a diagram of a velux window and dimensions from a flue but because it was picturing a vertical flue and not a horizontal flue like ours he was not interested. Isn’t the definition of a flue ‘an outlet producing waste gases’?
We have enlightened the neighbours with our concerns but after initially being concerned they have been reassured by their builder that their window is correct and it is our flue that is wrong, however according to regulations and plenty of measuring for reassurance our boiler has been fitted correctly.
All we want is for someone with some knowledge and authority to come and assess the situation so we can be reassured that we are not going to kill anyone because surely they have all of these rules and regulations for a reason.
 
your flue should be 300mm from the boundry line
you can add a plume management kit to direct it away from the roof window
 
The best thing to do is send the pictures to the boiler manufacturer and ask their advice. A flue terminal only has to be 300mm away from a opening/window. The plume you see which gets blown into the window is mostly water vapour and the actual flue gases will be heavily diluted by the outside air. But for your own piece of mind. Contact the manufacturer and they will tell you if it's right or not.
 
I’d give the manufacturers a call and see what their take on it is if you want full reassurance. It looks like an ideal terminal to me and just looking in one of their current manuals it states 300mm from an opening etc, only 2000mm if it’s a vertical flue.
Your situation isn’t on their plan, you could say an opening doesn’t include velux windows because they are specified further down the page, so before you start to shell out on a verticals flue, i’d certainly give the manufacturers a buzz.

Good luck




 
Thanks for all of the input. Spoken to Ideal and they verified the measurements as 2000mm below and 600mm to the side , as with the vertical flue. Was told to report to gas safe as breaching health and safety.....head and wall comes to mind.

I’m afraid it’s your problem, not theirs. Your boiler terminates over into their boundary. They can have you move it as a nuisance.
I would just get yours altered to a vertical flue. This should cost around the £500 mark, depending on access to the roof.

Is that correct?
I would have thought which ever was in place first has the right to be there (if installed st correct distances)

If it terminates over there boundary and isn’t to regs spacing yes they can inform you to move your flue
 
But it doesn’t terminate over the neighbours boundary
They built an extension with a window too close to the existing flue
 
If the boiler was there before the extention then it's not your problem. The builder should have seeked professional advice from a plumber to make sure they could build the wall and put a velux so close to the flue.
I would still advise that you send a picture to ideal as the measurements they have given you are for a vertical flue, your flue is not vertical.
If they still reply saying the flue is wrong, then I would speak to your neighbours about contacting the builder to correct your flue at his expense.

The extension is on the neighbors land so is on there boundary
 
The flue in no way terminates over their boundary it runs parallel to it so that is not an issue. Concerning Ideal, I specifically asked them if the dimensions also related to horizontal flues to which they replied it didn’t matter if it was horizontal or vertical.

So below the flue is your land eg your conservatory / upvc structure
 
Debra, it’s one of those situations where it’s so grey. Yes it probably meets regs, but as you say if wind blows combustion products into that bedroom... morally it’ll play on your mind.
 
I'd still, for how long it will take, email a picture to ideal. You can easily misunderstand someone when talking over the phone. They will also advise you of your best option to safely terminate the flue.

Out of curiosity what was patched up below the flue? It looks like the same bricks as the extention so was this done at the same time the extention was been built?
 
Did you have a party wall agreement signed before the extension was undertaken? and if so what does it say?

boiler does not terminate over their property
