Not sure if it's what you're after, but I downloaded the free ideal app a couple of hours ago (I think just about all the manufacturers have apps). It lets you enter number of kitchens, bathrooms and utilities then gives you all the boiler options and asks you to select water and gas pressure to determine which one suits. It doesn’t take bedroom numbers or dims though? When you select a boiler it gives you the full spec and manual, you can register it via the app too. It also has Ideal's contact details etc so you can get in touch with support at the click of two buttons. I’m putting together a folder on my phone with all manufacturers apps so I have manuals etc close to hand for future ref.
