"AO charge £90-00 to install! "
Really. Well I'd be happy if they managed to take it around the back and into the kitchen. Connection is less of an issue.
I've never used them (John Lewis for me), but the latest online shops survey by Which? (December 2017) places them 3rd out of 100 online shops....just behind AllBeauty.com and RicherSounds.com.
90 quid!!?
Must be more for gas. I've been looking at electric cookers...think it was 34.99 for install and remove old. Still more than Argos, but probably a better selection.
