Asking for reduction after survey

[fourplusfour]

Had survey back on house I'm buying. Long list of category 3 concerns. I'm reviewing property at the weekend. If I decide to ask for a reduction in purchase price, should I broach the subject with vendors then or go through the estate agent?

Shouldn't it be through your solicitor? A formal offer.

Definitely not via the vendors.

Only in Scotland.

Id speak to the EA first.
