Less than 20 years after the discovery of the first examples of ionised winds in Active Galaxies, it is now largely accepted that outflowing ionised absorbers are a common and important occurrence of the central regions of AGN. These outflows are observed over a wide range of ionisation, column density and outflowing velocity, reaching up to 0.3c. While X-ray observations of AGN provided the evidence for the presence of fast outflowing winds launched from near the central massive black hole, we are just starting to build a more complete picture of winds on all scales: from hundreds of gravitational radii to pc or kpc scales. Here I will review the observational evidence for the fast outflows, their properties and their potential role for a significant feedback on the host galaxies. I will show our recent observational results obtained for the prototype of these powerful winds, PDS 456, and for a new extreme example, MCG-03-58-007. I will then summarise our recent results on the larger scale absorbers from the pc-scale ionised absorbers seen in the X-ray band to the kpc-scale molecular gas seen with ALMA.
