Not too sure what more we can do though. We've replaced both external doors which used to let the breeze in, and insulated the loft. I guess we could replace all the sash windows with PVC but don't really want to do that.
I've recently had my sash windows refurbished. Some were replaced with double glazed sashes which obviously made a difference but even the single glazed ones were made considerably warmer with proper draught proofing.
Yeah, it's pretty bad.
