Well....two years ago it took me 1,5 year and a lot of paperwork to renew my licence. If i had known this upfront I would have finished the build within the first licence period.

Regulations change and my initial licence took me only 6 months to get it. But every situation is different. It depends on which town you are, what type of land you have. If you are in protected area it can cost you years to get a licence. But I also heard from friends it took them only a few months.

Good luck,
Mark
