I had already decided I would get a cam for my new car, bit late now.
Not that it would have shown much apart from me not causing the accident by drifting from my own lane - He tried to exit from the roundabout from the inside lane whilst I was going straight on in the outside lane and whilst he eventually realised where I was he still scraped along the side of both drivers side doors.
I'd rather not claim as i'm getting rid of for buttons anyway but he thought I was at fault (we'll see what the insurance company says as the road markings are in my favour) and you can't trust anyone these days that I don't get a call from a solicitor in 6 months demanding something from me. So I'll be letting my insurance co know all about it.
I'll take a look
I think that Standard Size savings are more likely on doors or perhaps high end 3G, or products used by big players in the larger project market eg housing associations, rather than self-build. Might it be worth talking to someone in that market say Eurocell rather than the likes of Rationel etc.
Another option used by a couple on here have been dark coloured upvc and/or the 2G units that are now able to get to around 1.0 as a u-value.
For uPVC I think that the processes are now so tuned for volume that there may not be too much fat left to cut. The last house I did ... put te full quote on the forum somewhere ... came in at about £170 per sqm for 2G with 2 doors and a set of French windows in the quote. I think the custom turnaround was only slightly over a month.
The variations just on quotes are at least half or double, so there is much to be gained by sweating it.
Two threads very worth reading, including an amazing chart by @Visti comparing umpteen quotes for the same job.
