External insulation system and render for large bungalow - can I put monocouche over insulation?

I own a large bungalow, half of the building was timber rough cast and a brick extension was built many years ago. There was a big damp problem, we removed all the offending timber walls and replaced these with new external weatherboard/timber. The inside was insulated and plastered and looks normal! The outside however, I believe requires an insulation system to the timber part of the building and completely re-rendering however, we also enlisted the help of a very dodgy builder who cost us thousands and left us with no confidence in tradesmen...we've had quotes from £6000 - £16000 for the same job. We've been told you can't put monocouche etc over insulation because it will fall off, we've also been told that this is not true ....we can't spend another winter with weather sheets covering our home :(
