Chimney repair cost (rebuild or repoint & repair flaunching)

meanmum

We are buying a house where the survey has flagged problems with the chimney. It's a Victorian redbrick semi, original slate roof, one chimney stack on the centre ridge at the gable end of the house consolidating the 4 flues (2 of which are in use) so 4 chimney pots. The bricks look wonky, definitely need repointing as a minimum, with some replacing - and the flaunching needs repair. It might be bad enough to need taking down & rebuilding. Access for scaffolding is reasonable, as it's on the gable end of the house, with approx 2m between this wall & the next house, with a low dividing boundary wall in between.
Can anyone give me an idea of roughly what sort of cost to expect to repair/rebuild this. Thanks.

I would say your going to be on the wrong side of a £1000+ VAT if its going to need re-building. then depending on how much of the materials are salvageable, more on top.

Update - builder reckons only top 6 courses need rebuilding, rest is just repointing. Any suggestions on likely cost now it's better scoped? Scaffolding will be a major cost, I realise.....

Sounds like a days work, £200 plus materials plus scaffold which could be about £300-400
