French Door Prices...

I've had 3 quotes for my 1800 x 2100 french doors which are:

£800 for Veka 68mm profile, fully fitted but no fense cert
£620 for Spectus Elite 70 profile, supply only
£490 for Eurocell 70mm profile, supply only

I'm not worried about fitting myself if I have to but I was just wondering if the prices roughly reflected the quality of the doors I would be buying?

when you say you are not worried about fitting them yourself have you had any experience of fitting them ? they can be quite challenging even to an experienced fitter, the glazing units need to be installed correctly (toe and heel packers) to avoid later problems, and once you start adjusting the doors you can make things a whole lot worse if you dont know what you are doing.
But if you are confident fit them yourself and save £300 but put £70 of it towards a building notice then you dont need fensa.
