Hmm, strange...I stand corrected! I swear I saw the word continuous in the guidance notes, but you are correct. The paragraph below is what the guidance notes currently say (I just looked) and according to that wording, it seems you can pick and choose which 12 months out of the 15 to include. However, I would double and triple check that you have a true 12 month period and not slightly more (even by a day or two).
Perhaps someone else can comment? I could have claimed more than I did!

Although I don't think it would put me into the next income bracket.
To the original poster: it seems you *can* use the periods of April 2006 and June 2006-April 2007. I would explain that May is missing on purpose, just to be safe. I apologize for my mistake.

I don't think the HO will accept that.

I am in my final stage of applying for the HSMP and had a question for you;
1) Can i claim from April, 2006 to April, 2007 (May, 2006 exempted), or is it necessary that we need to claim for continous 12 months.
Your help will be much appreciated.
