flue/boiler advice

My boiler has just been condemmed as the flue which goes into a small lightwell is no longer allowed. I need to change my boiler anyway from a regular combi to, I guess, a condensing one (from what I've read) for a 1 bedroom flat. My main concern is what to do about the flue - it will need to reach up to the roof which is 3 floors away. Is this possible and is it true that some boilers can use regular plastic piping as flues? (or it seems that I'll be paying around £40 per metre for extension pieces). Any suggestions or advice on the best boiler and flue to get would be greatly appreciated. Thanks.

Have you bought the flat? what`s a lightwell FFS whatever boiler you had must have been vented adequately without going 3 stories away, a clue would be handy, look at the top of your boiler where does the big white pipe go? Does it go straight up through the ceiling? Or out through the wall?
It currently goes straight out into lightwell which was apparently ok to do when I bought the flat and installed it there 12 years ago.

Practically speaking that probably would need scaffolding adding about £900 to the cost of the job!

Apart from the problem that Kestons have not proved very reliable, a better solution would be to discharge across your flat thus saving the scaffolding cost.

Is it possible/allowed to run a flue from the boiler inside my kitchen and along the top of my sitting room walls and out through the main external wall? (not ideal but guess could box it in but would also need planning permission for flue to exit this wall - my upstairs neighbours are currently applying for their new boiler flue). It seems all the options are quite difficult.

A Flue in a lightwell must be within 1 metre of top level to allow proper disperssion of products. so your best bet is try and find somewhere else for boiler

In spite of what Namsag says, it IS possible to box in a flue PROVIDING access panels are fitted so that all the joints can be inspected!

You done even need to box it in either!

Do you mean 1 metre above the top of the lightwell?

Thanks for boxing info as don't really fancy a flue going across sitting room that isn't boxed in if go for this option.
 
No below the top level

Agile is of course right you can leave access panels but a flue must be inspectable along its entire length not just sections

That'll mean it will be close to neighbours windows which are about 1m down from roof level so guess back to square one. Think this is going to be a very expensive nightmare.
 
No that is the most below the top it can go, but it can go above roof level which is better.
but its going to be dear and very limited choice
