How are you going with your walls @tmoyn?
Let us know if you need a hand with anything.
I'm still going... Scraped all the wallpaper and flakey paint off, cleaned walls with sugar soap and now finally at primer stage. Never done any serious painting before but ready to give it a go.
I'm going to use the suggested, British Paints 4L White 4 In 1 Prep Water Based Primer Sealer Undercoat and see how it goes.
You've done the hard part @tmoyn. All the best with the painting. Feel free to post anytime you need a hand with anything.
Looking forward to seeing the end results.
