Hi,

My house was built in the early 1980s. It was constructed with a flue
which met the BS 1289:1975 - from my research this means the plaster
can be directly attached to the flue. The standard was revised after
my house constructed with BS 1289:1986 - which states that plaster
cannot be directly attached to the flue.

A local tradesman recently installed a gas fire into my flue. Whenever
I have the fire on for above 30 minutes, the plaster gets too warm and
starts cracking. He claims he's not responsible as the flue did not
comply with regulations. I claim that it does comply with regulations,
and he should of been aware that houses constructed between 1975 and
1986 could have these difficulties.

Please can you confirm who's correct?

Thanks,
Gareth

1) Was there no fire connected to the flue before?

2) If there was (and it seems highly likely, considering it's a flue) why
did the plaster not crack then?

3) How do you know the plaster is cracking after 30 mins?

And it's not up to the tradesman to put right your plaster, it's up to you
to get it right so that the heat doesn't crack it up, try dry lining it with
expanding foam behind the p-board for insulation.
