Hi dse, ours said A class and I think B1. Don't really know what any of it means though!
I would be interested to know how much people's site works are, as we signed up in 2011 with Redink and having no building experience we were nervous of how much site works would cost, so we got them to cap it. We should get a reduction, as they based their figure on S class and C I think, and we did get them to say if it comes in lower then they would pass the saving on, but now of course I'm worried that they won't and that we would have got a better deal closer to the actual build time! There's no way of knowing if they're being honest with the price is there, so I would like to know what more recent redinkers were quoted for this estate, if you don't mind sharing. I'm happy to share our figure - it was $16k something!
