A little brick hiccup!

Upon checking out brick colours on the PGH website (in all my spare time!), I discovered that my chosen brick colour CHOCOLATTO has changed Basix classification from medium to dark. THe documentation that EBH gave me at tender said it was medium; my visit to PGH had it at medium and Home Options Gallery didn't pick this up. Given our Basix certificate has been issued already based on our colour selections etc, I was a little worried to say the least. No other colours in our allocated brick range remotely excited me and I had already spent much time getting the colour scheme how I wanted it.
I had a decision to make....Do I call EBH and discuss with the potential of having to re-do colours and select a brick I don't like? Do I stick my head in the sand and let them discover the change? I then had visions of the BASIX inspector (is there one?) coming at the completion of the house & asking us to demolish as it doesn't comply. I know, a little catastrophising! I decided to ring my upline Manager to have a quiet chat. Bev made my day! She checked the file & discovered that on the Basix certificate the external wall colours have not actually been specified. This basically means we are free to choose whatever colour we wish. Interesting as the Basix documentation we signed stated that our external colours were medium grade.
Phew! I can sleep well tonight & not have nightmares about the house being pulled down at the 11th hour!
