Make sure that you check the exempted development section of the planning regulations to ensure that you dont need planning permission. Link is as follows:
Also note that if you are commencing the works now, you are oblidged to comply with the recently released Part L, with regard to energy efficiency, link below:
You are likely to have difficulty in making sense of Part L by yourself. The main point to note is that you are now required to provide much higher insulation levels in your extension/conversion than you would have had to if you had converted the garage pre November 2011.
